Interapy, treatment of posttraumatic stress through the Internet: a controlled trial

Efficacy of digital mental health interventions for PTSD symptoms: A systematic review of meta-analyses

BACKGROUND

The present systematic review aimed to synthesize the results of meta-analyses which examine the effects of digital mental health interventions (DMHIs) on post-traumatic stress disorder (PTSD) symptoms, and investigate whether intervention characteristics (i.e., technique, timeframe, and therapeutic guidance) and methodological characteristics including outcome measures and sample inclusion criteria (age, gender, socioeconomic status, country, comorbidity) moderate the efficacy of digital interventions.

METHODS

A systematic search of various sources (ECSCOhost PsycInfo, PubMed, Web of Science, Scopus, EBSCOhost ERIC, Google Scholar, ProQuest Dissertations & Theses) including five peer-reviewed journals was conducted to identify relevant meta-analyses up to December 2023, and 11 meta-analyses were included in the final review.

RESULTS

Overall, our review elucidates that DMHIs are appropriate for alleviating PTSD symptoms in adults, with more consistent evidence supporting the efficacy of cognitive behavioral therapy (CBT)-based, compared to non-CBT-based, interventions when compared to control conditions. However, we found inconclusive evidence that the efficacy of DMHIs varied according to intervention timeframe, therapeutic guidance, or sample characteristics.

LIMITATIONS

A relatively limited number of different populations was sampled across meta-analyses. Further, while our review focused on PTSD symptoms to indicate the efficacy of digital interventions, other indices of effectiveness were not examined.

CONCLUSION

Our findings indicate the clinical utility of DMHIs for managing PTSD symptoms particularly when CBT-based intervention techniques are employed.

The change of working alliance and the association to treatment outcome in an internet-based therapy after pregnancy loss

BACKGROUND

Working alliance is a prominent non-specific factor for treatment outcomes in face-to-face and internet-based interventions. The association between working alliance and therapy outcome appears to be time- and disorder-specific, but less is known about the change of working alliance during the intervention and the impact of working alliance in grief-specific interventions. The present study examines the association between the change of working alliance and treatment outcomes in an internet-based intervention for parents who experienced pregnancy loss.

METHODS

228 participants received a grief intervention based on cognitive behavioral therapy with asynchronous text-based therapist feedback. Prolonged grief and related symptoms of traumatic stress, depression, anxiety, and general psychopathology were assessed with validated instruments before and after the intervention. The change of working alliance was assessed using the short version of the Working Alliance Inventory at mid-treatment (session 4) and the end of the treatment (session 10).

RESULTS

Data for N = 146 persons was analyzed. Working alliance in total and all subscales increased significantly from sessions 4 to 10. This change in working alliance correlated significantly with a reduction in prolonged grief. Changes in subscales of working alliance also correlated with symptoms of depression and general psychopathology. Regression analysis showed that a change in working alliance predicted a reduction in prolonged grief but did not predict improvements in other grief-related symptoms.

CONCLUSION

The results examine the change of working alliance during an internet-based intervention and the association with treatment outcome. A small impact of change in working alliance on treatment outcome of prolonged grief was confirmed, but not on related symptoms. Further research is needed to assess moderators of the alliance-outcome association to improve internet-based interventions.

The efficacy of internet-delivered cognitive-behavioral therapy for posttraumatic stress disorder according to the mean age of patients: a systematic review and meta-analysis

Internet-delivered cognitive-behavioral therapy (I-CBT) is effective in treating post-traumatic stress disorder (PTSD) symptoms, offering enhanced accessibility and cost-effectiveness. However, it's important to note that these technologies may not be suitable for all age groups. Therefore, we conducted a systematic review and meta-analysis to determine if the effectiveness of I-CBT in treating PTSD varies based on the patients' mean age. We conducted a systematic review of the literature, focusing on randomized controlled trials (RCTs) in the ISI Web of Science, PubMed/MEDLINE, and PsycINFO databases. Following this, we performed a meta-analysis and evaluated the risk of bias using the Cochrane risk of bias quality assessment tool. In this study, we examined patient-related factors (civil or military status, age, and gender), clinical characteristics (baseline PTSD severity and type of trauma), and treatment characteristics (type of intervention, synchronous or asynchronous delivery, and the number of sessions) as independent variables. The dependent variable was the reduction in mean PTSD symptoms. Five RCTs out of 1,552 screened studies were included in this review, all of which showed some level of concern regarding potential bias. Our meta-analysis indicates that I-CBT is equally effective regardless of patients' mean age. Since all RCTs included only provide the mean age of the patients, further randomized controlled trials should address the effectiveness of I-CBT among different age groups.

Impact of COVID‐19 social distancing measures on routine mental health care provision and treatment outcome for common mental disorders in the Netherlands

Objective

The uptake of digital interventions in mental health care (MHC) has been slow, as many therapists and patients believe that in‐person contact is essential for establishing a good working relationship and good outcomes in treatment. The public health policies regarding social distancing during the coronavirus disease‐2019 (COVID‐19) pandemic forced an abrupt transformation of MHC provisions for outpatients: Since mid‐March 2020, nearly all in‐person contact was replaced with videoconferencing. The COVID‐19 crisis offered a unique opportunity to investigate whether MHC with videoconferencing yields inferior results as compared to in‐person interventions.

Method

In a large urban MHC facility in the Netherlands, measurement‐based care is routine practice. Outcome data are regularly collected to support shared decision making and monitor patient progress. For this study, pretest and post‐test data were used to compare outcomes for three cohorts: treatments performed prior to, partially during and entirely during the COVID‐19 lockdown. Outcomes were compared in two large data sets: Basic MHC (N = 1392) and Specialized MHC (N = 1040).

Results

Therapeutic outcomes appeared robust for COVID‐19 conditions across the three cohorts: No differences in outcomes were found between treatments that were conducted during lockdown compared to in‐person treatments prior to COVID‐19, or treatments which started in‐person, but needed to be continued by means of videoconferencing.

Discussion

Videoconferencing care during the COVID‐19 pandemic had similar outcomes compared to traditional in‐person care. These real‐world results corroborate findings of previous randomized controlled studies and meta‐analyses in which videoconferencing and in‐person care has been directly compared in terms of clinical effectiveness.

Sleep management in posttraumatic stress disorder: a systematic review and meta-analysis

OBJECTIVE

Post-traumatic stress disorder (PTSD) can lead to many negative secondary outcomes for patients, including sleep disturbances. The objective of this meta-analysis is (1) to evaluate the effect of interventions for adults with PTSD on sleep outcomes, PTSD outcomes, and adverse events, and (2) to evaluate the differential effectiveness of interventions aiming to improve sleep compared to those that do not.

METHODS

Nine databases were searched for relevant randomized controlled trials (RCTs) in PTSD from January 1980 to October 2019. Two independent reviewers screened 7176 records, assessed 2139 full-text articles, and included 89 studies in 155 publications for this review. Sleep, PTSD, and adverse event outcomes were abstracted and meta-analyses were performed using the Hartung-Knapp-Sidik-Jonkman method for random effects.

RESULTS

Interventions improved sleep outcomes (standardized mean difference [SMD] -0.56; confidence interval [CI] -0.75 to -0.37; 49 RCTs) and PTSD symptoms (SMD -0.48; CI -0.67 to -0.29; 44 RCTs) across studies. Adverse events were not related to interventions overall (RR 1.17; CI 0.91 to 1.49; 15 RCTs). Interventions targeting sleep improved sleep outcomes more than interventions that did not target sleep (p = 0.03). Improvement in PTSD symptoms did not differ between intervention types.

CONCLUSIONS

Interventions for patients with PTSD significantly improve sleep outcomes, especially interventions that specifically target sleep. Treatments for adults with PTSD directed towards sleep improvement may benefit patients who suffer from both ailments.

Anger and predictors of drop-out from PTSD treatment of veterans and first responders

BACKGROUND

Drop-out is an important barrier in treating post-traumatic stress disorder (PTSD) with consequences that negatively impact clients, clinicians and mental health services as a whole. Anger is a common experience in people with PTSD and is more prevalent in military veterans. To date, no research has examined if anger may predict drop-out in military veterans or first responders.

AIMS

The present study aimed to determine the variables that predict drop-out among individuals receiving residential treatment for PTSD.

METHOD

Ninety-five military veterans and first responders completed pre-treatment measures of PTSD symptom severity, depression, anxiety, anger, and demographic variables. Logistic regression analyses were used to determine if these variables predicted drop-out from treatment or patterns of attendance.

RESULTS

Female gender was predictive of drop-out. However, when analysed by occupation female gender was predictive of drop-out among first responders and younger age was predictive of drop-out in military participants. Anger, depression, anxiety and PTSD symptom severity were not predictive of drop-out in any of the analyses. No variables were found to predict attendance patterns (consistent or inconsistent) or early versus late drop-out from the programme.

CONCLUSION

These results suggest that although anger is a relevant issue for treating PTSD, other factors may be more pertinent to drop-out, particularly in this sample. In contrast with other findings, female gender was predictive of drop-out in this study. This may indicate that in this sample, there are unique characteristics and possible interacting variables that warrant exploration in future research.

Initial outcomes of couple HOPES: A guided online couple intervention for PTSD and relationship enhancement

Couple HOPES (Helping Overcome PTSD and Enhance Satisfaction) is a guided, online couple intervention adapted from Cognitive-Behavioral Conjoint Therapy for posttraumatic stress disorder (PTSD). It was created to overcome a range of barriers to accessing evidence-based treatments for PTSD and the intimate relationship problems associated with it. This manuscript describes initial outcomes of the intervention in a series of 10 couples. Participants were military, veteran and first responders with probable PTSD and their intimate partners. Couples completed the program and measurements of PTSD, relationship satisfaction, and secondary outcomes at pre-, mid-, and post-intervention. Mean satisfaction for the program was high and it was completed by seven of ten couples. Participants with PTSD evidenced significant and large pre- to post-intervention effect size improvements in PTSD symptoms (g = 0.80) and perceived health (g = 1.13). They also exhibited non-significant but medium effect size pre- to post-intervention improvements in quality of life (g = 0.62), and depression (g = 0.53), and small effect size pre- to post-intervention improvements in argumentativeness (g = 0.43), anger (g = 0.31), and anxiety (g = 0.31). Partners reported significant and moderate pre- to post-intervention effect size improvements in relationship satisfaction (g = 0.68), and medium but not significant effect size improvements in accommodation of PTSD (g = 0.56). Results provide initial support for the feasibility, acceptability, and efficacy of Couple HOPES for improving PTSD and relationship satisfaction. However, more testing in larger samples, including with randomized controlled designs, is needed.

Internet-based cognitive and behavioural therapies for post-traumatic stress disorder (PTSD) in adults

BACKGROUND

Therapist-delivered trauma-focused psychological therapies are effective for post-traumatic stress disorder (PTSD) and have become the accepted first-line treatments. Despite the established evidence-base for these therapies, they are not always widely available or accessible. Many barriers limit treatment uptake, such as the number of qualified therapists available to deliver the interventions; cost; and compliance issues, such as time off work, childcare, and transportation, associated with the need to attend weekly appointments. Delivering Internet-based cognitive and behavioural therapy (I-C/BT) is an effective and acceptable alternative to therapist-delivered treatments for anxiety and depression.

OBJECTIVES

To assess the effects of I-C/BT for PTSD in adults.

SEARCH METHODS

We searched MEDLINE, Embase, PsycINFO and the Cochrane Central Register of Controlled Trials to June 2020. We also searched online clinical trial registries and reference lists of included studies and contacted the authors of included studies and other researchers in the field to identify additional and ongoing studies.

SELECTION CRITERIA

We searched for RCTs of I-C/BT compared to face-to-face or Internet-based psychological treatment, psychoeducation, wait list, or care as usual. We included studies of adults (aged over 16 years), in which at least 70% of the participants met the diagnostic criteria for PTSD, according to the Diagnostic and Statistical Manual (DSM) or the International Classification of Diseases (ICD).

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed abstracts, extracted data, and entered data into Review Manager 5. The primary outcomes were severity of PTSD symptoms and dropouts. Secondary outcomes included diagnosis of PTSD after treatment, severity of depressive and anxiety symptoms, cost-effectiveness, adverse events, treatment acceptability, and quality of life. We analysed categorical outcomes as risk ratios (RRs), and continuous outcomes as mean differences (MD) or standardised mean differences (SMDs), with 95% confidence intervals (CI). We pooled data using a fixed-effect meta-analysis, except where heterogeneity was present, in which case we used a random-effects model. We independently assessed the included studies for risk of bias and we evaluated the certainty of available evidence using the GRADE approach; we discussed any conflicts with at least one other review author, with the aim of reaching a unanimous decision.

MAIN RESULTS

We included 13 studies with 808 participants. Ten studies compared I-C/BT delivered with therapist guidance to a wait list control. Two studies compared guided I-C/BT with I-non-C/BT. One study compared guided I-C/BT with face-to-face non-C/BT. There was substantial heterogeneity among the included studies. I-C/BT compared with face-to-face non-CBT Very low-certainty evidence based on one small study suggested face-to-face non-CBT may be more effective than I-C/BT at reducing PTSD symptoms post-treatment (MD 10.90, 95% CI 6.57 to 15.23; studies = 1, participants = 40). There may be no evidence of a difference in dropout rates between treatments (RR 2.49, 95% CI 0.91 to 6.77; studies = 1, participants = 40; very low-certainty evidence). The study did not measure diagnosis of PTSD, severity of depressive or anxiety symptoms, cost-effectiveness, or adverse events. I-C/BT compared with wait list Very low-certainty evidence showed that, compared with wait list, I-C/BT may be associated with a clinically important reduction in PTSD post-treatment (SMD -0.61, 95% CI -0.93 to -0.29; studies = 10, participants = 608). There may be no evidence of a difference in dropout rates between the I-C/BT and wait list groups (RR 1.25, 95% CI 0.97 to 1.60; studies = 9, participants = 634; low-certainty evidence). I-C/BT may be no more effective than wait list at reducing the risk of a diagnosis of PTSD after treatment (RR 0.53, 95% CI 0.28 to 1.00; studies = 1, participants = 62; very low-certainty evidence). I-C/BT may be associated with a clinically important reduction in symptoms of depression post-treatment (SMD -0.51, 95% CI -0.97 to -0.06; studies = 7, participants = 473; very low-certainty evidence). Very low-certainty evidence also suggested that I-C/BT may be associated with a clinically important reduction in symptoms of anxiety post-treatment (SMD -0.61, 95% CI -0.89 to -0.33; studies = 5, participants = 345). There were no data regarding cost-effectiveness. Data regarding adverse events were uncertain, as only one study reported an absence of adverse events. I-C/BT compared with I-non-C/BT There may be no evidence of a difference in PTSD symptoms post-treatment between the I-C/BT and I-non-C/BT groups (SMD -0.08, 95% CI -0.52 to 0.35; studies = 2, participants = 82; very low-certainty evidence). There may be no evidence of a difference between dropout rates from the I-C/BT and I-non-C/BT groups (RR 2.14, 95% CI 0.97 to 4.73; studies = 2, participants = 132; I² = 0%; very low-certainty evidence). Two studies found no evidence of a difference in post-treatment depressive symptoms between the I-C/BT and I-non-C/BT groups (SMD -0.12, 95% CI -0.78 to 0.54; studies = 2, participants = 84; very low-certainty evidence). Two studies found no evidence of a difference in post-treatment symptoms of anxiety between the I-C/BT and I-non-C/BT groups (SMD 0.08, 95% CI -0.78 to 0.95; studies = 2, participants = 74; very low-certainty evidence). There were no data regarding cost-effectiveness. Data regarding adverse effects were uncertain, as it was not discernible whether adverse effects reported were attributable to the intervention.

AUTHORS' CONCLUSIONS

While the review found some beneficial effects of I-C/BT for PTSD, the certainty of the evidence was very low due to the small number of included trials. This review update found many planned and ongoing studies, which is encouraging since further work is required to establish non-inferiority to current first-line interventions, explore mechanisms of change, establish optimal levels of guidance, explore cost-effectiveness, measure adverse events, and determine predictors of efficacy and dropout.

Developing a theoretically grounded, digital, ecological momentary intervention for parental bereavement care using the ORBIT model-Phase 1

Current models of bereavement care do not address all of bereaved parents' unique needs. Diverse challenges limit parents' ability to access certain bereavement services. A web-based intervention prototype for bereaved parents was developed. Using convenience and snowball techniques, 14 participants (pediatric providers, software developers, and bereaved parents) were enrolled in a descriptive, cross-sectional feasibility and usability study. While the intervention was generally considered acceptable, three themes were identified to enhance its usability and acceptability: timing; delivery; and revisions. Further intervention development is needed to improve both short- and long-term physical and psychological outcomes for bereaved parents.

Psychotherapists' perception of their clinical skills and in-session feelings in live therapy versus online therapy during the COVID-19 pandemic: a pilot study

During the coronavirus disease 2019 (COVID-19) pandemic, many psychotherapists who were used to seeing their patients in face-toface setting adapted to providing therapies online. In the present pilot study, we investigated therapist current experiences of online therapy compared to live therapy. Twenty-nine therapists completed Clinical Skills, Difficulties in Practice, and in-sessions feelings of Flow, Boredom and Anxiety of the Trainee Current Progress Report, giving a score for each item in two different conditions: Live Therapy and Online Therapy. Compared to Live Therapy, in Online Therapy therapists reported significantly less Clinical Skills, whereas Difficulties in Practice did not differ in the considered conditions. With regard to in-sessions feeling, therapists reported significantly lower scores of Boring and higher scores of Flow in Live Therapy compared to Online Therapy, whereas Anxiety did not differed in the considered conditions.

Comparative efficacy and acceptability of expressive writing treatments compared with psychotherapy, other writing treatments, and waiting list control for adult trauma survivors: a systematic review and network meta-analysis

BACKGROUND

Expressive writing about a traumatic event is promising in treating posttraumatic stress disorder (PTSD) symptoms in adult trauma survivors. To date, the comparative efficacy and acceptability of this approach is uncertain. Therefore, we aimed to examine the comparative efficacy and acceptability of expressive writing treatments.

METHODS

We included 44 RCTs with 7724 participants contributing 54 direct comparisons between expressive writing (EW), enhanced writing (i.e. including additional therapist contact or individualized writing assignments; EW+), PTSD psychotherapies (PT), neutral writing (NW), and waiting-list control (WL).

RESULTS

EW, EW+, PT, and NW were statistically significantly more efficacious than WL at the longest available follow-up, with SMDs (95% CI) of -0.78 (-1.10 to -0.46) for PT, -0.81 (-1.02 to -0.61) for EW+ , -0.43 (-0.65 to -0.21) for EW, and -0.37 (-0.61 to -0.14) for NW. We found small to moderate differences between the active treatments. At baseline mean PTSD severity was significantly lower in EW+ compared with WL. We found considerable heterogeneity and inconsistency and we found elevated risk of bias in at least one of the bias dimensions in all studies. When EW+-WL comparisons were excluded from the analyses EW+ was no longer superior compared with EW.

CONCLUSIONS

The summarized evidence confirms that writing treatments may contribute to improving PTSD symptoms in medium to long-term. Methodological issues in the available evidence hamper definite conclusions regarding the comparative efficacy and acceptability of writing treatments. Adequately sized comparative randomized controlled trials preferably including all four active treatment approaches, reporting long-term data, and including researchers with balanced preferences are needed.

PTSD Coach Online-Arabic: A Randomized Controlled Pilot Trial to Examine Feasibility, Acceptability, and Preliminary Effectiveness

The Egyptian Revolution of 2011 resulted in high-level exposure to sociopolitical violence, placing a large burden on the mental health care system that cannot be effectively met given the small number of available providers in Egypt. We conducted a nonblinded, randomized controlled pilot trial of an online, self-directed tool for managing posttraumatic stress symptoms (PTSS). The study aimed to evaluate the feasibility, acceptability, and preliminary effectiveness of the PTSD Coach Online-Arabic. Trauma-exposed Egyptian adults with clinically significant PTSS (N = 87; intervention group: n = 41) completed assessments at baseline, weekly over the treatment period, posttest, and 3-month follow-up. Of participants who completed weekly surveys, 88.9% used the program; 22.0% of participants reported regular, weekly use. Most tools received good likeability and perceived benefit scores, but lower perceived benefit scores on three tools suggest that some content may require additional adaptation. Intent-to-treat analyses using multilevel modeling with multiple imputation to account for missing data were conducted. Effect sizes for PTSS were below the cutoff for small effects at posttest, d = -0.14, but demonstrated a small positive effect at 3-months, d = -0.25. There was a small positive effect of treatment on anxiety at posttest, d = -0.37, and a medium effect at 3-month follow-up, d = -0.49. Treatment effects for depressed mood were below the cutoff for small effects at posttest and 3-months, ds = -0.14 and -0.18. These findings suggest that the PTSD Coach Online-Arabic may be a promising supplemental resource for support in this setting.

Exposure-Based Writing Therapies for Subthreshold and Clinical Posttraumatic Stress Disorder: A Systematic Review and Meta-Analysis

We undertook a systematic review to assess the efficacy of exposure-based writing therapies (WTs) for trauma-exposed adults with subthreshold or clinical levels of posttraumatic stress disorder. Four databases (PsycINFO, Medline, Wiley Online, PILOTS) were searched for randomized controlled trials (RCTs) of exposure-based WTs. A total of 13 RCTs that reported on results from 17 WT versus control comparisons were included. The primary outcomes were posttraumatic stress symptom severity at posttreatment and/or clinical response. An overall unclear or high risk of bias was identified in 84.6% of studies. In comparison to both waitlist k = 3, Hedges' g = -0.97, 95% CI [-1.20, -0.73], and placebo writing conditions, k = 9, Hedges' g = -0.48, 95% CI [-0.87, -0.08], WTs were more beneficial to participants. There was no evidence of a difference between WTs that were longer in duration compared to other psychotherapy, k = 2; pooled OR = 1.42; 95% CI [0.83, 2.43]. These findings indicate that exposure-based WTs are effective when compared to waitlist and placebo writing control conditions. The evidence needs to be considered in the context of the modest number of studies conducted to date, the high methodological heterogeneity between the studies, and the high or unclear risk of bias across many studies. Further research is needed to increase the evidence base regarding the efficacy of WTs for posttraumatic stress. Future research should also measure the mediators and predictors of outcomes to further develop protocols and understand which variants of WTs work for different populations or individuals.

Lessons learned in adapting an online intervention program for posttraumatic stress for use in Egypt

Cultural adaptation of evidence-based treatments is a pressing priority for global health, and previous research has informed recommendations for guiding the process of translation and adaptation. As research in the domain of cultural adaptation and evaluation of evidence-based treatments progresses, it is critical that researchers communicate key lessons learned, so that models of adaptation can be continuously refined and reconsidered. The work described in this article aimed to translate and culturally adapt an online intervention to address symptoms of posttraumatic stress-the PTSD Coach Online-for use with young adults in Egypt. The cultural adaptation framework proposed by Bernal and colleagues (1995) was used, and focus groups and interviews with members of the target population, mental health professionals, and service users were conducted. The authors encountered a number of challenges in treatment adaptation that generated important insights for future work. Specifically, this case study highlights the importance of translation teams with diverse backgrounds and experiences, the critical nature of iterative feedback throughout the adaptation process, and the importance of a long time-horizon for optimal adaptation.

Efficacy of an Internet-based cognitive-behavioural grief therapy for people bereaved by suicide: a randomized controlled trial

Background: The loss of a loved one due to suicide can be a traumatic event associated with prolonged grief and psychological distress. Objective: This study examined the efficacy of an Internet-based cognitive-behavioural grief therapy (ICBGT) specifically for people bereaved by suicide. Methods: In a randomized controlled trial, 58 participants with prolonged grief disorder (PGD) symptoms who had lost a close person to suicide were randomly allocated either to the intervention group (IG) or waitlist-control group (WCG). The 5-week intervention comprised ten writing assignments in three phases: self-confrontation, cognitive restructuring, and social sharing. Symptoms of PGD, common grief reactions after suicide, depression, and general psychopathology were assessed at pre-, post-test and follow-up. Results: Between-group effect sizes were large for the improvement of PGD symptoms in treatment completers (d_ppc2 = 1.03) and the intent-to-treat analysis (d_ppc2 = 0.97). Common grief reactions after suicide and depressive symptoms also decreased in the IG compared to the WCG (moderate to large effects). The results are stable over time. Only for general psychopathology, there was no significant time by group interaction effect found. Conclusions: The ICBGT represents an effective treatment approach for people suffering from PGD symptoms after bereavement by suicide. Considering the effect sizes, the small treatment dose, duration, and the stability of the results, the ICBGT constitutes an appropriate alternative to face-to-face grief interventions.

Digital Interventions for PTSD Symptoms in the General Population: a Review

There has been a significant development of digital interventions for the treatment of Post-Traumatic Symptom Disorder (PTSD) over the past two decades. However, the majority of research has examined their clinical efficacy for military service members and veteran populations whereas community-based trauma survivors have received significantly less attention. Their effectiveness for this population, therefore, remains unclear. The aim of this review was to evaluate the effectiveness of digitally delivered psychological therapies to alleviate PTSD symptomatology in the general population. Findings showed that digitally delivered Cognitive Behavioural Therapy (iCBT) produced more consistently significant improvements in PTSD symptoms, compared to interapy, expressive writing, psychoeducation, mindfulness, cognitive tasks and psychosocial interventions. iCBT - associated improvements were also independent of the focus (i.e. trauma vs. non-trauma) of the intervention, the provision of therapeutic support (e.g. guided vs. unguided), type of feedback (e.g. automated vs. individualised) or the number of sessions provided. Nevertheless, the number of included studies for subgroup analyses was relatively low. Digital interventions have an enormous potential to improve accessibility, efficiency, clinical effectiveness and personalisation of mental health interventions. Future research is needed to investigate further the use of a wider range of therapeutic approaches across different clinical and subclinical groups and settings and test the impact of these interventions (or components) against a wider range of comparison conditions (e.g. face to face CBT) with optimal power.

E-health applications in the field of traumatic stress

E-health offers great potential in the field of traumatic stress to deliver training, assessment, prevention, and treatment of adverse outcomes after trauma worldwide. In order to encourage research on E-health applications in the field of traumatic stress, this current special issue of the European Journal of Psychotraumatology presents a series of papers divided into three emergent topics: I) development of digital interventions, II) the use of digital interventions to foster self-management and deliver therapy, and III) digital methods to improve prediction, assessment, and monitoring of post-trauma outcomes. These studies show acceptance of the tools by various end-user groups and improvements of current research and clinical practices, but also areas for improvement regarding the development process and making even better use of technological capabilities of E-Health. We propose three general themes to accelerate the quality of e-Health interventions and studies in this area in the coming years: optimizing user engagement and adherence, conducting more (innovative) research, and increasing implementation and dissemination activities. This issue appears in the midst of the COVID-19 pandemic. It is exactly at times like these that we need effective online interventions and we see an enormous increase in the use of e-Health. We hope this issue will contribute to help those affected and to serve the community worldwide.

Interventions for adults with a history of complex traumatic events: the INCiTE mixed-methods systematic review

BACKGROUND

People with a history of complex traumatic events typically experience trauma and stressor disorders and additional mental comorbidities. It is not known if existing evidence-based treatments are effective and acceptable for this group of people.

OBJECTIVE

To identify candidate psychological and non-pharmacological treatments for future research.

DESIGN

Mixed-methods systematic review.

PARTICIPANTS

Adults aged ≥ 18 years with a history of complex traumatic events.

INTERVENTIONS

Psychological interventions versus control or active control; pharmacological interventions versus placebo.

MAIN OUTCOME MEASURES

Post-traumatic stress disorder symptoms, common mental health problems and attrition.

DATA SOURCES

Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1937 onwards); Cochrane Central Register of Controlled Trials (CENTRAL) (from inception); EMBASE (1974 to 2017 week 16); International Pharmaceutical Abstracts (1970 onwards); MEDLINE and MEDLINE Epub Ahead of Print and In-Process & Other Non-Indexed Citations (1946 to present); Published International Literature on Traumatic Stress (PILOTS) (1987 onwards); PsycINFO (1806 to April week 2 2017); and Science Citation Index (1900 onwards). Searches were conducted between April and August 2017.

REVIEW METHODS

Eligible studies were singly screened and disagreements were resolved at consensus meetings. The risk of bias was assessed using the Cochrane risk-of-bias tool and a bespoke version of a quality appraisal checklist used by the National Institute for Health and Care Excellence. A meta-analysis was conducted across all populations for each intervention category and for population subgroups. Moderators of effectiveness were assessed using metaregression and a component network meta-analysis. A qualitative synthesis was undertaken to summarise the acceptability of interventions with the relevance of findings assessed by the GRADE-CERQual checklist.

RESULTS

One hundred and four randomised controlled trials and nine non-randomised controlled trials were included. For the qualitative acceptability review, 4324 records were identified and nine studies were included. The population subgroups were veterans, childhood sexual abuse victims, war affected, refugees and domestic violence victims. Psychological interventions were superior to the control post treatment for reducing post-traumatic stress disorder symptoms (standardised mean difference -0.90, 95% confidence interval -1.14 to -0.66; number of trials = 39) and also for associated symptoms of depression, but not anxiety. Trauma-focused therapies were the most effective interventions across all populations for post-traumatic stress disorder and depression. Multicomponent and trauma-focused interventions were effective for negative self-concept. Phase-based approaches were also superior to the control for post-traumatic stress disorder and depression and showed the most benefit for managing emotional dysregulation and interpersonal problems. Only antipsychotic medication was effective for reducing post-traumatic stress disorder symptoms; medications were not effective for mental comorbidities. Eight qualitative studies were included. Interventions were more acceptable if service users could identify benefits and if they were delivered in ways that accommodated their personal and social needs.

LIMITATIONS

Assessments about long-term effectiveness of interventions were not possible. Studies that included outcomes related to comorbid psychiatric states, such as borderline personality disorder, and populations from prisons and humanitarian crises were under-represented.

CONCLUSIONS

Evidence-based psychological interventions are effective and acceptable post treatment for reducing post-traumatic stress disorder symptoms and depression and anxiety in people with complex trauma. These interventions were less effective in veterans and had less of an impact on symptoms associated with complex post-traumatic stress disorder.

FUTURE WORK

Definitive trials of phase-based versus non-phase-based interventions with long-term follow-up for post-traumatic stress disorder and associated mental comorbidities.

STUDY REGISTRATION

This study is registered as PROSPERO CRD42017055523.

Digitally Delivered Psychological Interventions for Anxiety Disorders: a Comprehensive Review

Digital interventions for anxiety disorders have been well-researched over the past two decades. However, reviews to date have focused on internet-based cognitive behavioural therapy (iCBT), whereas other psychological interventions have received less attention. The aim of this review was therefore to evaluate the effectiveness of digitally delivered psychological therapies (CBT, Attention Bias Modification, Exposure Therapy, Applied Relaxation, Bibliotherapy, Psychodynamic Therapy, Mindfulness, Behavioural Stress Management, Counselling) compared with control conditions and/or other psychological interventions for anxiety disorders (Social Anxiety Disorder (SAD), Health Anxiety, Obsessive-Compulsive Disorder (OCD), Post-traumatic Stress Disorder (PTSD), Specific Phobias, Panic Disorder (PD), Generalised Anxiety Disorder (GAD)]. 68 randomised controlled trials (RCTs) were reviewed. SAD was the anxiety disorder for which the most RCTs were conducted. Overall, findings support the effectiveness of iCBT for SAD; for the remaining interventions, although some RCTs indicated significant improvement (within groups) at post-treatment and/or follow up, between group findings were less consistent and overall, methodological differences across trials failed to provide strong supporting evidence. Finally, the level of therapist contact or expertise did not appear to affect much treatment effectiveness. Additional large, methodologically rigorous trials are needed to investigate further whether different digitally delivered psychological interventions are equally effective for anxiety disorders. Moreover, further studies are pertinent in order to examine the maintenance of therapy gains after the end of treatments and understand how these work [(e.g. the influence of therapist factors, user engagement and/or satisfaction, potential access barriers and treatments with diverse population groups (e.g. BME groups)].

A Meta-Analysis of Expressive Writing on Posttraumatic Stress, Posttraumatic Growth, and Quality of Life

Expressive writing is beneficial for promoting both positive psychological and physical health outcomes. Unfortunately, inhibiting emotions is related to impairments in psychological and physical health. James Pennebaker and others have used expressive writing as an experimental manipulation to gauge its efficacy in treating a wide variety of physical and psychological outcomes. While many studies have been conducted that examine the efficacy of expressive writing across such outcomes, a considerable amount of these studies tend to neglect necessary considerations, such as different levels of symptomatology, power, and meaningfulness of respective effect sizes. Six previous meta-analyses have been conducted that examine expressive writing’s effect on psychological outcomes. However, these studies focus on the experimental versus control group effect size. Thus, our meta-analysis sought to examine the efficacy of an expressive writing task on only the experimental conditions in studies measuring posttraumatic stress, posttraumatic growth, and quality of life using random effects models. Results indicated a small overall effect size for posttraumatic stress and negligible to small effect sizes for posttraumatic growth and quality of life. However, those studies requiring a diagnosis of posttraumatic stress disorder (PTSD) exhibited a medium to large effect size. Implications for future research design and interpretation of published research are discussed.

Internet-based cognitive and behavioural therapies for post-traumatic stress disorder (PTSD) in adults

BACKGROUND

Therapist-delivered trauma-focused psychological therapies are an effective treatment for post-traumatic stress disorder (PTSD). These have become the accepted first-line treatments for the disorder. Despite the established evidence-base for these therapies, they are not always widely available or accessible. Many barriers limit treatment uptake, such as the limited number of qualified therapists to deliver the interventions, cost, and compliance issues, such as time off work, childcare, and transportation, associated with the need to attend weekly appointments. Delivering cognitive behavioural therapy (CBT) on the Internet is an effective and acceptable alternative to therapist-delivered treatments for anxiety and depression. However, fewer Internet-based therapies have been developed and evaluated for PTSD, and uncertainty surrounds the efficacy of Internet-based cognitive and behavioural therapy (I-C/BT) for PTSD.

OBJECTIVES

To assess the effects of I-C/BT for PTSD in adults.

SEARCH METHODS

We searched the Cochrane Common Mental Disorders Group's Specialised Register (CCMDCTR) to June 2016 and identified four studies meeting the inclusion criteria. The CCMDCTR includes relevant randomised controlled trials (RCT) from MEDLINE, Embase, and PsycINFO. We also searched online clinical trial registries and reference lists of included studies, and contacted researchers in the field to identify additional and ongoing studies. We ran an update search on 1 March 2018, and identified four additional completed studies, which we added to the analyses along with two that were previously awaiting classification.

SELECTION CRITERIA

We searched for RCTs of I-C/BT compared to face-to-face or Internet-based psychological treatment, psychoeducation, wait list or care as usual. We included studies of adults (aged over 16 years or over), in which at least 70% of the participants met the diagnostic criteria for PTSD, according to the Diagnostic and Statistical Manual (DSM) or the International Classification of Diseases (ICD).

DATA COLLECTION AND ANALYSIS

We entered data into Review Manager 5 software. We analysed categorical outcomes as risk ratios (RRs), and continuous outcomes as mean differences (MD) or standardised mean differences (SMDs), with 95% confidence intervals (CI). We pooled data with a fixed-effect meta-analysis, except where heterogeneity was present, in which case we used a random-effects model. Two review authors independently assessed the included studies for risk of bias; any conflicts were discussed with a third author, with the aim of reaching a unanimous decision.

MAIN RESULTS

We included 10 studies with 720 participants in the review. Eight of the studies compared I-C/BT delivered with therapist guidance to a wait list control. Two studies compared guided I-C/BT with I-non-C/BT. There was considerable heterogeneity among the included studies.Very low-quality evidence showed that, compared with wait list, I-C/BT may be associated with a clinically important reduction in PTSD post-treatment (SMD -0.60, 95% CI -0.97 to -0.24; studies = 8, participants = 560). However, there was no evidence of a difference in PTSD symptoms when follow-up was less than six months (SMD -0.43, 95% CI -1.41 to 0.56; studies = 3, participants = 146). There may be little or no difference in dropout rates between the I-C/BT and wait list groups (RR 1.39, 95% CI 1.03 to 1.88; studies = 8, participants = 585; low-quality evidence). I-C/BT was no more effective than wait list at reducing the risk of a diagnosis of PTSD after treatment (RR 0.53, 95% CI 0.28 to 1.00; studies = 1, participants = 62; very low-quality evidence). I-C/BT may be associated with a clinically important reduction in symptoms of depression both post-treatment (SMD -0.61, 95% CI -1.17 to -0.05; studies = 5, participants = 425; very low-quality evidence). Very low-quality evidence also suggested that I-C/BT may be associated with a clinically important reduction in symptoms of anxiety post-treatment (SMD -0.67, 95% CI -0.98 to -0.36; studies = 4, participants = 305), and at follow-up less than six months (MD -12.59, 95% CI -20.74 to -4.44; studies = 1, participants = 42; very low-quality evidence). The effects of I-C/BT on quality of life were uncertain (SMD 0.60, 95% CI 0.08 to 1.12; studies = 2, participants = 221; very low-quality evidence).Two studies found no difference in PTSD symptoms between the I-C/BT and I-non-C/BT groups when measured post-treatment (SMD -0.08, 95% CI -0.52 to 0.35; studies = 2, participants = 82; very low-quality evidence), or when follow-up was less than six months (SMD 0.08, 95% CI -0.41 to 0.57; studies = 2, participants = 65; very low-quality evidence). However, those who received I-C/BT reported their PTSD symptoms were better at six- to 12-month follow-up (MD -8.83, 95% CI -17.32 to -0.34; studies = 1, participants = 18; very low-quality evidence). Two studies found no difference in depressive symptoms between the I-C/BT and I-non-C/BT groups when measured post-treatment (SMD -0.12, 95% CI -0.78 to 0.54; studies = 2, participants = 84; very low-quality evidence) or when follow-up was less than six months (SMD 0.20, 95% CI -0.31 to 0.71; studies = 2, participants = 61; very low-quality evidence). However, those who received I-C/BT reported their depressive symptoms were better at six- to 12-month follow-up (MD -8.34, 95% CI -15.83 to -0.85; studies = 1, participants = 18; very low-quality evidence). Two studies found no difference in symptoms of anxiety between the I-C/BT and I-non-C/BT groups when measured post-treatment (SMD 0.08, 95% CI -0.78 to 0.95; studies = 2, participants = 74; very low-quality evidence) or when follow-up was less than six months (SMD -0.16, 95% CI -0.67 to 0.35; studies = 2, participants = 60; very low-quality evidence). However, those who received I-C/BT reported their symptoms of anxiety were better at six- to 12-month follow-up (MD -8.05, 95% CI -15.20 to -0.90; studies = 1, participants = 18; very low-quality evidence).None of the included studies reported on cost-effectiveness or adverse events.

AUTHORS' CONCLUSIONS

While the review found some beneficial effects of I-C/BT for PTSD, the quality of the evidence was very low due to the small number of included trials. Further work is required to: establish non-inferiority to current first-line interventions, explore mechanisms of change, establish optimal levels of guidance, explore cost-effectiveness, measure adverse events, and determine predictors of efficacy and dropout.

[Quality criteria of internet-based cognitive-behavioral interventions for children and adolescents and their parents - A systematic review]

Quality criteria of internet-based cognitive-behavioral interventions for children and adolescents and their parents - A systematic review Abstract. Introduction: This study provides an overview of existing internet-based evidence-based cognitive behavioral interventions (iCBT) for children/adolescents and their parents. The studies were evaluated based on preliminary defined quality criteria regarding their usability in the healthcare system. Methods: The review was performed according to PRISMA guidelines and evaluated the scientific literature concerning to iCBT. We conducted a comprehensive literature search of PubMed, PsychINFO, PsychARTICLES, PsychNDEX and Science Direct using relevant keywords. Studies were rated according to 10 previously predefined quality measures. Results: A total of 4,479 articles were screened, 62 of which were selected for further analysis. Thereof, 24 international iCBT programs with 50 randomized controlled trials (RCTs) were evaluated and met the quality criteria (M = 7.25, SD = 1.07). Further 13 publications showed preliminary efficacy for another 11 international iCBT programs and met the quality criteria (M = 7.45, SD = .82). There was no significant difference between programs evaluated within and without RCTs t(33) = -.56, p = .58. Conclusions: Our results indicate that multiple international iCBT programs exist. Because in Germany the waiting time for psychotherapeutic or psychiatric treatment is still about five months, iCBT programs have the potential to reduce this gap.

Interventions for common mental health problems among university and college students: A systematic review and meta-analysis of randomized controlled trials

Common mental health problems (CMHPs), such as depression, anxiety disorder, obsessive-compulsive disorder (OCD), and post-traumatic stress disorder (PTSD) are internalizing disorders with high comorbidity. University and college students are under many stressors and transitional events, and students fall within the age range when CMHPs are at their developmental peak. Compared to the expanded effort to explore and treat CMHPs, there has been no a meta-analysis that comprehensively reviewed the interventions for CMHPs and examined the effects of interventions for CMHPs in college students. The objective of this review is to conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) examining interventions for CMHPs among university and college students and to estimate their post-intervention effect size (ES), as well as follow-up ES, for depression, anxiety disorder, OCD and PTSD separately. Meta-analytic procedures were conducted in accordance with PRISMA guidelines. We reviewed 7768 abstracts from which 331 full-text articles were reviewed and 51 RCTs were included in the analysis. We found moderate effect sizes for both depression (Hedges' g = -0.60) and anxiety disorder (Hedges' g = -0.48). There was no evidence that existing interventions for OCD or PTSD were effective in this population. For interventions with high number of papers, we performed subgroup analysis and found that cognitive behavioral therapy (CBT) and mindfulness-based interventions were effective for both depression and generalized anxiety disorder (GAD), and attention/perception modification was effective for GAD; other interventions (i.e. art, exercise and peer support) had the highest ES for both depression and GAD among university and college students.

Posttraumatic stress disorder and positive memories: Clinical considerations

Encoding and retrieval difficulties, and avoidance of both traumatic and positive memories, are associated with posttraumatic stress disorder (PTSD) symptoms. However, most PTSD research and clinical work has solely examined the role of traumatic memories in the maintenance/resolution of PTSD symptoms. This review provides a comprehensive discussion of the literature on positive memories and PTSD. First, we review theories and evidence on the relations between trauma, PTSD, and memory processes (particularly positive memories). Next, we propose a conceptual model that integrates evidence from experimental and positive/memory-based intervention research and highlights hypothesized mechanisms underlying the potential effectiveness of targeting positive memories in PTSD interventions. Specifically, we discuss how targeting positive memories could (1) increase positive affect and reduce negative affect, (2) correct negative cognitions, (3) increase specificity of retrieving autobiographical memories, and (4) be effectively integrated/sequenced with and enhance the effects of trauma-focused interventions. Lastly, we suggest clinical research avenues for investigating the relations between positive memories and PTSD, to possibly alter the current PTSD intervention paradigm focused only on traumatic memories. Overall, our proposed model drawing from experimental and intervention research, and outlining potential effects of targeting positive memories to reduce PTSD severity, needs further empirical investigation.

Internet interventions: Past, present and future

Internet interventions have been around now for about 20 years. While the field still suffers from a scattered terminology a large number of programs and studies exist. In the present paper I present an overview of my experiences of studying internet-supported cognitive-behaviour therapy (ICBT), but also mention other approaches including the use of smartphones. The paper covers the history of ICBT, short-term effects in controlled trials for a range of conditions, long-term effects, comparisons against face-to-face therapy, effectiveness studies, prediction studies, how the treatment is perceived, critique, and finally future directions. I conclude that we have now reached a stage in which we have numerous evidence-based treatments and procedures, and increasingly internet interventions including ICBT are disseminated.

Working alliance with an avatar: How far can we go with internet interventions?

OBJECTIVE

To examine the working alliance between users and an avatar and users' treatment expectations in an unguided Internet intervention for the treatment of insomnia.

METHODS

The sample included participants from the treatment condition (N = 29) of a randomised controlled trial. The task and goal subscales of the Working Alliance Inventory Short Revised (WAI-SR) were applied in week three. Five items of the Bern Post-Session Report and one question about the extent to which users had missed a human therapist were administered after each session. Treatment expectations were measured with the Credibility Expectancy Questionnaire (CEQ), and the Insomnia Severity Index (ISI) was used as the primary outcome measure.

RESULTS

The mean scores for the WAI-SR task and goal subscales were relatively high (M = 3.24, SD = 0.79; M = 3.16, SD = 0.91, respectively). The mean score of the five Bern Post-Session Report items remained stable over time, but some users increasingly indicated that they missed a real therapist over the course of the intervention, with a strong linear effect (t(87) = 3.16, p < 0.01). ISI chance score was predicted by the mean score of the Bern Post-Session Report (b = -0.3.83, t(21.80) = -2.97, p < 0.01), missing a human therapist (b = -0.0.13, t(20.47) = -2.72, p = 0.01) and the CEQ (b = 0.18, t(19.03) = -2.69, p = 0.01), but not by WAI-SR task and goal subscales.

CONCLUSIONS

Results indicate that users established a working alliance with the avatar. The affective bond remained stable over time, but towards the end of the intervention some users indicated that they missed having a human therapist. Affective bond and missing a real therapist predicted symptom change.

Internet-based grief therapy for bereaved individuals after loss due to Haematological cancer: study protocol of a randomized controlled trial

BACKGROUND

Approximately 10% of the individuals experiencing the death of a loved one develop prolonged grief disorder (PGD) after bereavement. Family members of haematological cancer patients might be particularly burdened since their loss experience is preceded by a very strenuous time of disease and aggressive treatment. However, support needs of relatives of cancer patients often remain unmet, also after the death of the patient. Therapeutic possibilities are enhanced by providing easily available and accessible Internet-based therapies. This study will adapt and evaluate an Internet-based grief therapy for bereaved individuals after the loss of a significant other due to haematological cancer.

METHODS

The efficacy of the Internet-based grief therapy is evaluated in a randomized controlled trial with a wait-list control group. Inclusion criteria are bereavement due to hematological cancer and meeting the diagnostic criteria for PGD. Exclusion criteria are severe depression, suicidality, dissociative tendency, psychosis, posttraumatic stress disorder, substance use disorder, and current psychotherapeutic or psychopharmacological treatment. The main outcome is PGD severity. Secondary outcomes are depression, anxiety, somatization, posttraumatic stress, quality of life, sleep quality, and posttraumatic growth. Data is collected pre- and posttreatment. Follow-up assessments will be conducted 3, 6, and 12 months after completion of the intervention. The Internet-based grief therapy is assumed to have at least moderate effects regarding PGD and other bereavement-related mental health outcomes. Predictors and moderators of the treatment outcome and PGD will be determined.

DISCUSSION

Individuals bereaved due to haematological cancer are at high risk for psychological distress. Tailored treatment for this particularly burdened target group is missing. Our study results will contribute to a closing of this healthcare gap.

A Meta-Analysis of the Impact of Universal and Indicated Preventive Technology-Delivered Interventions for Higher Education Students

The uses of technology-delivered mental health treatment options, such as interventions delivered via computer, smart phone, or other communication or information devices, as opposed to primarily face-to-face interventions, are proliferating. However, the literature is unclear about their effectiveness as preventive interventions for higher education students, a population for whom technology-delivered interventions (TDIs) might be particularly fitting and beneficial. This meta-analytic review examines technological mental health prevention programs targeting higher education students either without any presenting problems (universal prevention) or with mild to moderate subclinical problems (indicated prevention). A systematic literature search identified 22 universal and 26 indicated controlled interventions, both published and unpublished, involving 4763 college, graduate, or professional students. As hypothesized, the overall mean effect sizes (ESs) for both universal (0.19) and indicated interventions (0.37) were statistically significant and differed significantly from each other favoring indicated interventions. Skill-training interventions, both universal (0.21) and indicated (0.31), were significant, whereas non-skill-training interventions were only significant among indicated (0.25) programs. For indicated interventions, better outcomes were obtained in those cases in which participants had access to support during the course of the intervention, either in person or through technology (e.g., email, online contact). The positive findings for both universal and indicated prevention are qualified by limitations of the current literature. To improve experimental rigor, future research should provide detailed information on the level of achieved implementation, describe participant characteristics and intervention content, explore the impact of potential moderators and mechanisms of success, collect post-intervention and follow-up data regardless of intervention completion, and use analysis strategies that allow for inclusion of cases with partially missing data.

Effect of Patient-Therapist Gender Match on Psychotherapy Retention Among United States Veterans with Posttraumatic Stress Disorder

Extant literature suggests that patient-therapist gender matching may be associated with psychotherapy retention. We examined this relationship in a national cohort of Veterans (n = 506,471) initiating psychotherapy for posttraumatic stress disorder (PTSD) using multivariate logistic regression models. Overall, women were retained in psychotherapy at higher rates than men. When patient and therapist factors as well as practice patterns are considered, gender match between female patients with PTSD and female therapists was not a positive predictor of psychotherapy retention. Contrary to our expectations, gender match between male patients with PTSD and male therapist was a negative predictor of psychotherapy retention.

Young People, Adult Worries: Randomized Controlled Trial and Feasibility Study of the Internet-Based Self-Support Method "Feel the ViBe" for Adolescents and Young Adults Exposed to Family Violence

BACKGROUND

Adolescents and young adults (AYAs) are of special interest in a group of children exposed to family violence (FV). Past-year prevalence of exposure to FV is known to be highest in AYAs and has severe consequences. Peer support is an effective approach to behavior change and the Internet is considered suitable as a mode of delivery.

OBJECTIVE

The study aimed to evaluate both effectiveness and feasibility of a randomized controlled trial (RCT) and feasibility study of the Internet-based self-support method "Feel the ViBe" (FtV) using mixed-methods approach to fully understand the strengths and weaknesses of a new intervention.

METHODS

AYAs aged 12-25 years and exposed to FV were randomized in an intervention group (access to FtV + usual care) and a control group (minimally enhanced usual care) after they self-registered themselves. From June 2012 to July 2014, participants completed the Impact of Event Scale (IES) and Depression (DEP) and Anxiety (ANX) subscales of the Symptom CheckList-90-R (SCL-90) every 6 weeks. The Web Evaluation Questionnaire was completed after 12 weeks. Quantitative usage data were collected using Google analytics and content management system (CMS) logs and data files. A univariate analysis of variance (UNIANOVA) and mixed model analysis (intention-to-treat [ITT], complete case) were used to compare groups. Pre-post t tests were used to find within-group effects. Feasibility measures structurally address the findings. The CONsolidated Standards Of Reporting Trials of Electronic and Mobile HEalth Applications and onLine TeleHealth (CONSORT-EHEALTH) checklist was closely followed.

RESULTS

In total, 31 out of 46 participants in the intervention group and 26 out of 47 participants in the control group started FtV. Seventeen participants (intervention: n=8, control: n=9) completed all questionnaires. Mixed model analysis showed significant differences between groups on the SCL-90 DEP (P=.04) and ANX (P=.049) subscales between 6 and 12 weeks after participation started. UNIANOVA showed no significant differences. Pre-post paired sample t tests showed significant improvements after 12 weeks for the SCL-90 DEP (P=.03) and ANX (P=.046) subscales. Reported mean Web-based time per week was 2.83 with a session time of 36 min. FtV was rated a mean 7.47 (1-10 Likert scale) with a helpfulness score of 3.16 (1-5 Likert scale). All participants felt safe. Two-thirds of the intervention participants started regular health care.

CONCLUSIONS

No changes on the IES were found. SCL-90 DEP and ANX showed promising results; however, the calculated sample size was not reached (n=18). FtV functions best as a first step for adolescents and young adults in an early stage of change. FtV can be easily implemented without extensive resources and fits best in the field of public health care or national governmental care.

A Systematic Review and Meta-Analysis of e-Mental Health Interventions to Treat Symptoms of Posttraumatic Stress

BACKGROUND

Posttraumatic stress disorder (PTSD) is a stress disorder characterized by unwanted intrusive re-experiencing of an acutely distressing, often life-threatening, event, combined with symptoms of hyperarousal, avoidance, as well as negative thoughts and feelings. Evidence-based psychological interventions have been developed to treat these symptoms and reduce distress, the majority of which were designed to be delivered face-to-face with trained therapists. However, new developments in the use of technology to supplement and extend health care have led to the creation of e-Mental Health interventions.

OBJECTIVE

Our aim was to assess the scope and efficacy of e-Mental Health interventions to treat symptoms of PTSD.

METHODS

The following databases were systematically searched to identify randomized controlled trials of e-Mental Health interventions to treat symptoms of PTSD as measured by standardized and validated scales: the Cochrane Library, MEDLINE, EMBASE, and PsycINFO (in March 2015 and repeated in November 2016).

RESULTS

A total of 39 studies were found during the systematic review, and 33 (N=3832) were eligible for meta-analysis. The results of the primary meta-analysis revealed a significant improvement in PTSD symptoms, in favor of the active intervention group (standardized mean difference=-0.35, 95% confidence interval -0.45 to -0.25, P<.001, I2=81%). Several sensitivity and subgroup analyses were performed suggesting that improvements in PTSD symptoms remained in favor of the active intervention group independent of the comparison condition, the type of cognitive behavioral therapy-based intervention, and the level of guidance provided.

CONCLUSIONS

This review demonstrates an emerging evidence base supporting e-Mental Health to treat symptoms of PTSD.

EPA guidance on eMental health interventions in the treatment of posttraumatic stress disorder (PTSD)

The aim of this EPA guidance was to develop recommendations on eMental health interventions in the treatment of posttraumatic stress disorder (PTSD). A systematic literature search was performed and 40 articles were retrieved and assessed with regard to study characteristics, applied technologies, therapeutic approaches, diagnostic ascertainment, efficacy, sustainability of clinical effects, practicability and acceptance, attrition rates, safety, clinician-supported vs. non-supported interventions and active vs. waiting-list controls. The reviewed studies showed a great heterogeneity concerning study type, study samples, interventions and outcome measures. Based on these findings, five graded recommendations dealing with symptom reduction, acceptability, type of administration, clinician support, self-efficacy and coping were developed.

Does therapeutic writing help people with long-term conditions? Systematic review, realist synthesis and economic considerations

BACKGROUND

Writing therapy to improve physical or mental health can take many forms. The most researched model of therapeutic writing (TW) is unfacilitated, individual expressive writing (written emotional disclosure). Facilitated writing activities are less widely researched.

DATA SOURCES

Databases, including MEDLINE, EMBASE, PsycINFO, Linguistics and Language Behaviour Abstracts, Allied and Complementary Medicine Database and Cumulative Index to Nursing and Allied Health Literature, were searched from inception to March 2013 (updated January 2015).

REVIEW METHODS

Four TW practitioners provided expert advice. Study procedures were conducted by one reviewer and checked by a second. Randomised controlled trials (RCTs) and non-randomised comparative studies were included. Quality was appraised using the Cochrane risk-of-bias tool. Unfacilitated and facilitated TW studies were analysed separately under International Classification of Diseases, Tenth Revision chapter headings. Meta-analyses were performed where possible using RevMan version 5.2.6 (RevMan 2012, The Cochrane Collaboration, The Nordic Cochrane Centre, Copenhagen, Denmark). Costs were estimated from a UK NHS perspective and three cost-consequence case studies were prepared. Realist synthesis followed Realist and Meta-narrative Evidence Synthesis: Evolving Standards guidelines.

OBJECTIVES

To review the clinical effectiveness and cost-effectiveness of TW for people with long-term conditions (LTCs) compared with no writing, or other controls, reporting any relevant clinical outcomes. To conduct a realist synthesis to understand how TW might work, and for whom.

RESULTS

From 14,658 unique citations, 284 full-text papers were reviewed and 64 studies (59 RCTs) were included in the final effectiveness reviews. Five studies examined facilitated TW; these were extremely heterogeneous with unclear or high risk of bias but suggested that facilitated TW interventions may be beneficial in individual LTCs. Unfacilitated expressive writing was examined in 59 studies of variable or unreported quality. Overall, there was very little or no evidence of any benefit reported in the following conditions (number of studies): human immunodeficiency virus (six); breast cancer (eight); gynaecological and genitourinary cancers (five); mental health (five); asthma (four); psoriasis (three); and chronic pain (four). In inflammatory arthropathies (six) there was a reduction in disease severity [n = 191, standardised mean difference (SMD) -0.61, 95% confidence interval (CI) -0.96 to -0.26] in the short term on meta-analysis of four studies. For all other LTCs there were either no data, or sparse data with no or inconsistent, evidence of benefit. Meta-analyses conducted across all of the LTCs provided no evidence that unfacilitated emotional writing had any effect on depression at short- (n = 1563, SMD -0.06, 95% CI -0.29 to 0.17, substantial heterogeneity) or long-term (n = 778, SMD -0.04 95% CI -0.18 to 0.10, little heterogeneity) follow-up, or on anxiety, physiological or biomarker-based outcomes. One study reported costs, no studies reported cost-effectiveness and 12 studies reported resource use; and meta-analysis suggested reduced medication use but no impact on health centre visits. Estimated costs of intervention were low, but there was insufficient evidence to judge cost-effectiveness. Realist synthesis findings suggested that facilitated TW is a complex intervention and group interaction contributes to the perception of benefit. It was unclear from the available data who might benefit most from facilitated TW.

LIMITATION

Difficulties with developing realist synthesis programme theory meant that mechanisms operating during TW remain obscure.

CONCLUSIONS

Overall, there is little evidence to support the therapeutic effectiveness or cost-effectiveness of unfacilitated expressive writing interventions in people with LTCs. Further research focused on facilitated TW in people with LTCs could be informative.

Internet-delivered cognitive therapy for PTSD: a development pilot series

BACKGROUND

Randomised controlled trials have established that face-to-face cognitive therapy for posttraumatic stress disorder (CT-PTSD) based on Ehlers and Clark's cognitive model of PTSD is highly effective and feasible with low rates of dropout. Access to evidence-based psychological treatments for PTSD is insufficient. Several studies have shown that therapist-assisted treatment delivery over the Internet is a promising way of improving access to cognitive behavioural therapy interventions.

OBJECTIVE

To develop an Internet version of CT-PTSD that significantly reduces therapist contact time without compromising treatment integrity or retention rates.

METHODS

We describe the development of an Internet version of CT-PTSD. It implements all the key procedures of face-to-face CT-PTSD, including techniques that focus on the trauma memory, such as memory updating, stimulus discrimination and revisiting the trauma site, as well as restructuring individually relevant appraisals relating to overgeneralisation of danger, guilt, shame or anger, behavioural experiments and planning activities to reclaim quality of life. A cohort of 10 patients meeting DSM-IV criteria for PTSD worked through the programme, with remote guidance from a therapist, and they were assessed at pre- and post-treatment on PTSD outcome, mood, work and social adjustment and process measures.

RESULTS

No patients dropped out. Therapists facilitated the treatment with 192 min of contact time per patient, plus 57 min for reviewing the patient's progress and messages. Internet-delivered CT-PTSD was associated with very large improvements on all outcome and process measures, with 80% of patients achieving clinically significant change and remission from PTSD.

CONCLUSIONS

Internet-delivered cognitive therapy for PTSD (iCT-PTSD) appears to be an acceptable and efficacious treatment. Therapist time was reduced to less than 25% of time in face-to-face CT-PTSD. Randomised controlled trials are required to evaluate systematically the acceptability and efficacy of iCT-PTSD.

EFFECTIVENESS OF INTERNET-DELIVERED COGNITIVE BEHAVIORAL THERAPY FOR POSTTRAUMATIC STRESS DISORDER: A SYSTEMATIC REVIEW AND META-ANALYSIS

BACKGROUND

Internet-delivered cognitive behavioral therapy (iCBT) is a relatively novel treatment method that may improve the accessibility of mental health care for individuals with posttraumatic stress disorder (PTSD). The aim of this meta-analysis was to evaluate the effectiveness of iCBT compared to inactive (waitlist control and treatment-as-usual (TAU)) and active other interventions in reducing PTSD symptoms.

METHODS

A meta-analysis of 12 randomized controlled trials (14 comparisons) and 1,306 participants was conducted.

RESULTS

The pooled effect size of the 11 comparisons (10 studies, 1,139 participants) that compared iCBT to waitlist and TAU control was moderate (g = 0.71, 95% CI [0.49-0.93], P < .001), and showed moderate heterogeneity. The pooled effect size of the three studies (three comparisons) comparing iCBT to other interventions was small (g = 0.28, 95% CI [-0.00 to 0.56], P = .05), with low heterogeneity.

CONCLUSION

The findings of this systematic review and meta-analysis show that iCBT is an effective treatment for individuals with PTSD and comorbid depressive symptoms. However, further research is needed for effective dissemination of iCBT in clinical practice.

[Personalized Internet-based treatment services for posttraumatic stress disorder]

Among the most important innovations within the psychotherapeutic care system are the new opportunities in the field of e-mental health. During the past decade, Internet-based and other e-mental health approaches for the treatment of post-traumatic stress disorder and related stress-associated symptoms have been developed in great variety. Solely Internet-based self-help programs are the lowest-threshold approaches in a stepped-care system. By contrast, individualized online psychotherapy and virtual reality programs are at the opposite pole of the spectrum. Approaches in the field of m(obile)-mental health complement these new developments in psychotherapy. The existing evidence supports the clinical efficacy of all the described approaches, although not all have been tested rigorously analog to phase III studies in psychopharmacology. Nonetheless, e-mental health approaches will shape our field more and more in the future.

Online Counseling

This article reviews the online-counseling literature with an emphasis on current applications and considerations for future research. It focuses on primary themes of counseling psychology including the history of process-outcome research and multiculturalism. It explores current gaps in the literature from a counseling psychology framework, including the field’s focus on normal and developmental challenges and tasks, client strength and resilience, education and career development, prevention and wellness, and multiculturalism. In general, current evidence indicates that online counseling may be a viable service option for some clients, especially those who are typically isolated; however, questions remain regarding the effectiveness and appropriateness of online counseling.

Does Early Psychological Intervention Promote Recovery From Posttraumatic Stress?

In the wake of the terrorist attacks at the World Trade Center, more than 9,000 counselors went to New York City to offer aid to rescue workers, families, and direct victims of the violence of September 11, 2001. These mental health professionals assumed that many New Yorkers were at high risk for developing posttraumatic stress disorder (PTSD), and they hoped that their interventions would mitigate psychological distress and prevent the emergence of this syndrome. Typically developing in response to horrific, life-threatening events, such as combat, rape, and earthquakes, PTSD is characterized by reexperiencing symptoms (e.g., intrusive recollections of the trauma, nightmares), emotional numbing and avoidance of reminders of the trauma, and hyperarousal (e.g., exaggerated startle, difficulty sleeping). People vary widely in their vulnerability for developing PTSD in the wake of trauma. For example, higher cognitive ability and strong social support buffer people against PTSD, whereas a family or personal history of emotional disorder heightens risk, as does negative appraisal of one's stress reactions (e.g., as a sign of personal weakness) and dissociation during the trauma (e.g., feeling unreal or experiencing time slowing down). However, the vast majority of trauma survivors recover from initial posttrauma reactions without professional help. Accordingly, the efficacy of interventions designed to mitigate acute distress and prevent long-term psychopathology, such as PTSD, needs to be evaluated against the effects of natural recovery. The need for controlled evaluations of early interventions has only recently been widely acknowledged.

Psychological debriefing—the most widely used method—has undergone increasing empirical scrutiny, and the results have been disappointing. Although the majority of debriefed survivors describe the experience as helpful, there is no convincing evidence that debriefing reduces the incidence of PTSD, and some controlled studies suggest that it may impede natural recovery from trauma. Most studies show that individuals who receive debriefing fare no better than those who do not receive debriefing. Methodological limitations have complicated interpretation of the data, and an intense controversy has developed regarding how best to help people in the immediate wake of trauma.

Recent published recommendations suggest that individuals providing crisis intervention in the immediate aftermath of the event should carefully assess trauma survivors' needs and offer support as necessary, without forcing survivors to disclose their personal thoughts and feelings about the event. Providing information about the trauma and its consequences is also important. However, research evaluating the efficacy of such “psychological first aid” is needed.

Some researchers have developed early interventions to treat individuals who are already showing marked stress symptoms, and have tested methods of identifying those at risk for chronic PTSD. The single most important indicator of subsequent risk for chronic PTSD appears to be the severity or number of posttrauma symptoms from about 1 to 2 weeks after the event onward (provided that the event is over and that there is no ongoing threat).

Cognitive-behavioral treatments differ from crisis intervention (e.g., debriefing) in that they are delivered weeks or months after the trauma, and therefore constitute a form of psychotherapy, not immediate emotional first aid. Several controlled trials suggest that certain cognitive-behavioral therapy methods may reduce the incidence of PTSD among people exposed to traumatic events. These methods are more effective than either supportive counseling or no intervention.

In this monograph, we review risk factors for PTSD, research on psychological debriefing, recent recommendations for crisis intervention and the identification of individuals at risk of chronic PTSD, and research on early interventions based on cognitive-behavioral therapy. We close by placing the controversy regarding early aid for trauma survivors in its social, political, and economic context.

Therapist-supported Internet cognitive behavioural therapy for anxiety disorders in adults

BACKGROUND

Cognitive behavioural therapy (CBT) is an evidence-based treatment for anxiety disorders. Many people have difficulty accessing treatment, due to a variety of obstacles. Researchers have therefore explored the possibility of using the Internet to deliver CBT; it is important to ensure the decision to promote such treatment is grounded in high quality evidence.

OBJECTIVES

To assess the effects of therapist-supported Internet CBT (ICBT) on remission of anxiety disorder diagnosis and reduction of anxiety symptoms in adults as compared to waiting list control, unguided CBT, or face-to-face CBT. Effects of treatment on quality of life and patient satisfaction with the intervention were also assessed.

SEARCH METHODS

We searched the Cochrane Depression, Anxiety and Neurosis Review Group Specialised Register (CCDANCTR) to 16 March 2015. The CCDANCTR includes relevant randomised controlled trials from MEDLINE, EMBASE, PsycINFO and CENTRAL. We also searched online clinical trial registries and reference lists of included studies. We contacted authors to locate additional trials.

SELECTION CRITERIA

Each identified study was independently assessed for inclusion by two authors. To be included, studies had to be randomised controlled trials of therapist-supported ICBT compared to a waiting list, attention, information, or online discussion group; unguided CBT (that is, self-help); or face-to-face CBT. We included studies that treated adults with an anxiety disorder (panic disorder, agoraphobia, social phobia, post-traumatic stress disorder, acute stress disorder, generalized anxiety disorder, obsessive compulsive disorder, and specific phobia) defined according to the Diagnostic and Statistical Manual of Mental Disorders III, III-R, IV, IV-TR or the International Classification of Disesases 9 or 10.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed the risk of bias of included studies and judged overall study quality. We used data from intention-to-treat analyses wherever possible. We assessed treatment effect for the dichotomous outcome of clinically important improvement in anxiety using a risk ratio (RR) with 95% confidence interval (CI). For disorder-specific and general anxiety symptom measures and quality of life we assessed continuous scores using standardized mean differences (SMD). We examined statistical heterogeneity using the I(2) statistic.

MAIN RESULTS

We screened 1736 citations and selected 38 studies (3214 participants) for inclusion. The studies examined social phobia (11 trials), panic disorder with or without agoraphobia (8 trials), generalized anxiety disorder (5 trials), post-traumatic stress disorder (2 trials), obsessive compulsive disorder (2 trials), and specific phobia (2 trials). Eight remaining studies included a range of anxiety disorder diagnoses. Studies were conducted in Sweden (18 trials), Australia (14 trials), Switzerland (3 trials), the Netherlands (2 trials), and the USA (1 trial) and investigated a variety of ICBT protocols. Three primary comparisons were identified, therapist-supported ICBT versus waiting list control, therapist-supported versus unguided ICBT, and therapist-supported ICBT versus face-to-face CBT.Low quality evidence from 11 studies (866 participants) contributed to a pooled risk ratio (RR) of 3.75 (95% CI 2.51 to 5.60; I(2) = 50%) for clinically important improvement in anxiety at post-treatment, favouring therapist-supported ICBT over a waiting list, attention, information, or online discussion group only. The SMD for disorder-specific symptoms at post-treatment (28 studies, 2147 participants; SMD -1.06, 95% CI -1.29 to -0.82; I(2) = 83%) and general anxiety symptoms at post-treatment (19 studies, 1496 participants; SMD -0.75, 95% CI -0.98 to -0.52; I(2) = 78%) favoured therapist-supported ICBT; the quality of the evidence for both outcomes was low.One study compared unguided CBT to therapist-supported ICBT for clinically important improvement in anxiety at post-treatment, showing no difference in outcome between treatments (54 participants; very low quality evidence). At post-treatment there were no clear differences between unguided CBT and therapist-supported ICBT for disorder-specific anxiety symptoms (5 studies, 312 participants; SMD -0.22, 95% CI -0.56 to 0.13; I(2) = 58%; very low quality evidence) or general anxiety symptoms (2 studies, 138 participants; SMD 0.28, 95% CI -2.21 to 2.78; I(2) = 0%; very low quality evidence).Compared to face-to-face CBT, therapist-supported ICBT showed no significant differences in clinically important improvement in anxiety at post-treatment (4 studies, 365 participants; RR 1.09, 95% CI 0.89 to 1.34; I(2) = 0%; low quality evidence). There were also no clear differences between face-to-face and therapist supported ICBT for disorder-specific anxiety symptoms at post-treatment (7 studies, 450 participants; SMD 0.06, 95% CI -0.25 to 0.37; I(2) = 60%; low quality evidence) or general anxiety symptoms at post-treatment (5 studies, 317 participants; SMD 0.17, 95% CI -0.35 to 0.69; I(2) = 78%; low quality evidence).Overall, risk of bias in included studies was low or unclear for most domains. However, due to the nature of psychosocial intervention trials, blinding of participants and personnel, and outcome assessment tended to have a high risk of bias. Heterogeneity across a number of the meta-analyses was substantial, some was explained by type of anxiety disorder or may be meta-analytic measurement artefact due to combining many assessment measures. Adverse events were rarely reported.

AUTHORS' CONCLUSIONS

Therapist-supported ICBT appears to be an efficacious treatment for anxiety in adults. The evidence comparing therapist-supported ICBT to waiting list, attention, information, or online discussion group only control was low to moderate quality, the evidence comparing therapist-supported ICBT to unguided ICBT was very low quality, and comparisons of therapist-supported ICBT to face-to-face CBT were low quality. Further research is needed to better define and measure any potential harms resulting from treatment. These findings suggest that therapist-supported ICBT is more efficacious than a waiting list, attention, information, or online discussion group only control, and that there may not be a significant difference in outcome between unguided CBT and therapist-supported ICBT; however, this latter finding must be interpreted with caution due to imprecision. The evidence suggests that therapist-supported ICBT may not be significantly different from face-to-face CBT in reducing anxiety. Future research should explore heterogeneity among studies which is reducing the quality of the evidence body, involve equivalence trials comparing ICBT and face-to-face CBT, examine the importance of the role of the therapist in ICBT, and include effectiveness trials of ICBT in real-world settings. A timely update to this review is needed given the fast pace of this area of research.

Mobile mental health interventions following war and disaster

Mobile technologies offer potentially critical ways of delivering mental health support to those experiencing war, ethnic conflict, and human-caused and natural disasters. Research on Internet interventions suggests that effective mobile mental health technologies can be developed, and there are early indications that they will be acceptable to war and disaster survivors, and prove capable of greatly increasing the reach of mental health services. Promising mhealth interventions include video teleconferencing, text messaging, and smartphone-based applications. In addition, a variety of social media platforms has been used during and immediately after disasters to increase agility in responding, and strengthen community and individual resilience. Globally, PTSD Coach has been downloaded over 243,000 times in 96 countries, and together with large-scale use of social media for communication during disasters, suggests the potential for reach of app technology. In addition to enabling improved self-management of post-trauma problems, mobile phone interventions can also enhance delivery of face-to-face care by mental health providers and increase the effectiveness of peer helpers and mutual aid organizations. More research is needed to establish the efficacy of mhealth interventions for those affected by war and disaster. Research should also focus on the identification of active elements and core processes of change, determination of effective ways of increasing adoption and engagement, and explore ways of combining the various capabilities of mobile technologies to maximize their impact.

Internet-based interventions for posttraumatic stress: A meta-analysis of randomized controlled trials

Posttraumatic stress disorder (PTSD) is a prevalent and highly distressing affliction, but access to trauma-focused psychotherapy is limited. Internet-based interventions (IBIs) could improve the delivery of and access to specialized mental health care. Currently, no meta-analytical evidence is available on IBIs for PTSD. We conducted a meta-analysis of 20 randomized controlled studies, including 21 comparisons, in order to summarize the current state of efficacy for the treatment of PTSD and to identify moderator variables. Studies tested internet-based cognitive behavioral therapy (CBT) and expressive writing (EW) against active or passive comparison conditions, including subclinical and clinical samples. Results show that at post-assessment CBT-IBIs are significantly more efficacious than passive controls, resulting in medium to large effects on the PTSD sum and all sub-symptom scores (0.66<g<0.83), but both EW and CBT are not superior to active controls. EW differed from controls only at follow-up in reducing intrusions and hyperarousal, but based on merely two studies. Subgroup analyses reveal that for CBT none of the program components such as provision of therapeutic support, reminders, or number of sessions serves as a moderator. Overall, results for CBT-IBIs are promising, but the number of includable studies for subgroup analyses was low, limiting statistical power. Future research is necessary to systematically investigate the impact of treatment components and test against active controls with optimal power.

Challenges and Successes in Dissemination of Evidence-Based Treatments for Posttraumatic Stress: Lessons Learned From Prolonged Exposure Therapy for PTSD

Posttraumatic stress disorder (PTSD) poses monumental public health challenges because of its contribution to mental health, physical health, and both interpersonal and social problems. Recent military engagements in Iraq and Afghanistan and the multitude of resulting cases of PTSD have highlighted the public health significance of these conditions. There are now psychological treatments that can effectively treat most individuals with PTSD, including active duty military personnel, veterans, and civilians. We begin by reviewing the effectiveness of these treatments, with a focus on prolonged exposure (PE), a cognitive-behavioral therapy (CBT) for PTSD. Many studies conducted in independent research labs have demonstrated that PE is highly efficacious in treating PTSD across a wide range of trauma types, survivor characteristics, and cultures. Furthermore, therapists without prior CBT experience can readily learn and implement the treatment successfully. Despite the existence of highly effective treatments like PE, the majority of individuals with PTSD receive treatments of unknown efficacy. Thus, it is crucial to identify the barriers and challenges that must be addressed in order to promote the widespread dissemination of effective treatments for PTSD. In this review, we first discuss some of the major challenges, such as a professional culture that often is antagonistic to evidence-based treatments (EBTs), a lack of clinician training in EBTs, limited effectiveness of commonly used dissemination techniques, and the significant cost associated with effective dissemination models. Next, we review local, national, and international efforts to disseminate PE and similar treatments and illustrate the challenges and successes involved in promoting the adoption of EBTs in mental health systems. We then consider ways in which the barriers discussed earlier can be overcome, as well as the difficulties involved in effecting sustained organizational change in mental health systems. We also present examples of efforts to disseminate PE in developing countries and the attendant challenges when mental health systems are severely underdeveloped. Finally, we present future directions for the dissemination of EBTs for PTSD, including the use of newer technologies such as web-based therapy and telemedicine. We conclude by discussing the need for concerted action among multiple interacting systems in order to overcome existing barriers to dissemination and promote widespread access to effective treatment for PTSD. These systems include graduate training programs, government agencies, health insurers, professional organizations, healthcare delivery systems, clinical researchers, and public education systems like the media. Each of these entities can play a major role in reducing the personal suffering and public health burden associated with posttraumatic stress.

Web-based psychotherapy for posttraumatic stress disorder in war-traumatized Arab patients: randomized controlled trial

Background

In recent years, armed conflicts in the Middle East have resulted in high rates of exposure to traumatic events. Despite the increasing demand of mental health care provision, ongoing violence limits conventional approaches of mental health care provision. Internet-based interventions for posttraumatic stress disorder (PTSD) have proved feasible and effective in Western countries, but their applicability and efficacy in war and conflict regions remains unknown.

Objective

This study investigated the efficacy of a cognitive behavioral Internet-based intervention for war-traumatized Arab patients, with focus on Iraq.

Methods

A total of 159 individuals with PTSD participated in a parallel group randomized trial. Participants were randomly allocated by a computer-generated sequence to a treatment group (n=79) or a waiting list control group (n=80). The treatment group received 2 weekly 45-minute cognitive behavioral interventions via Internet over a 5-week period (10 sessions in total). The primary outcome was recovery from posttraumatic stress symptoms.

Results

Posttraumatic stress symptoms were significantly reduced from baseline to posttreatment (intention-to-treat analysis) in the treatment group relative to the control group (F_1,157=44.29, P<.001, d=0.92). Treatment effects were sustained at 3-month follow-up. Completer analysis indicated that 29 of 47 patients (62%) in the treatment group had recovered from posttraumatic stress symptoms at posttreatment (reliable change and Posttraumatic Stress Diagnostic Scale score <20) versus 1 patient (2%) in the control group (OR 74.19, 95% CI 9.93-585.8, P<.001) indicating that the chance of recovering was 74.19 times higher in the treatment than in the control group.

Conclusions

The results indicate, even in unstable and insecure settings with ongoing exposure to human rights violations through war and dictatorships, people with posttraumatic stress symptoms benefit from a cognitive behavioral treatment provided entirely through the Internet. This method of delivery could improve patients’ access to humanitarian aid in the form of e-mental health services.

Researchers have therefore explored the possibility of using the Internet to deliver CBT; it is important to ensure the decision to promote such treatment is grounded in high quality evidence.

OBJECTIVES

To assess the effects of therapist-supported Internet CBT on remission of anxiety disorder diagnosis and reduction of anxiety symptoms in adults as compared to waiting list control, unguided CBT, or face-to-face CBT. Effects of treatment on quality of life and patient satisfaction with the intervention were also assessed.

SEARCH METHODS

We searched the Cochrane Depression, Anxiety and Neurosis Review Group Specialized Register (CCDANCTR) to 12 April 2013. The CCDANCTR includes relevant randomised controlled trials from EMBASE (1974 -), MEDLINE (1950 -) and PsycINFO (1967 -). We also searched online clinical trial registries and reference lists of included studies. We contacted authors to locate further trials. An update of an initial search (April 2013), conducted in September 2014, identified seven new completed studies, seven previously ongoing studies now completed, and four new ongoing studies. This is a fast-moving area; we plan to update this review shortly, incorporating these new studies.

SELECTION CRITERIA

Each identified study was independently assessed for inclusion by two authors. To be included, studies had to be randomised controlled trials of therapist-supported ICBT compared to a waiting list, attention, information, or online discussion group; unguided CBT (that is, self-help); or face-to-face CBT. We included studies that treated adults with an anxiety disorder (panic disorder, agoraphobia, social phobia, post-traumatic stress disorder, acute stress disorder, generalized anxiety disorder, obsessive compulsive disorder, and specific phobia) defined according to the Diagnostic and Statistical Manual of Mental Disorders III, III-R, IV, IV-TR or the International Classification of Disesases 9 or 10.

For disorder-specific and general anxiety symptom measures and quality of life we assessed continuous scores using standardized mean differences (SMD). We examined statistical heterogeneity using the I(2) statistic.

MAIN RESULTS

We screened 1000 citations and selected 30 studies (2181 participants) for inclusion. The studies examined social phobia (11 trials), panic disorder with or without agoraphobia (8 trials), generalized anxiety disorder (4 trials), post-traumatic stress disorder (1 trial), and specific phobia (1 trial). Five remaining studies included a range of anxiety disorder diagnoses. Studies were conducted in Sweden (15 trials), Australia (12 trials), Switzerland (2 trials), and the Netherlands (1 trial) and investigated a variety of ICBT protocols. Three primary comparisons were identified, experimental versus waiting list control, experimental versus unguided ICBT, and experimental versus face-to-face CBT.Moderate quality evidence from 9 studies (644 participants) contributed to a pooled RR of 4.18 (95% CI 2.42 to 7.22) for clinically important improvement in anxiety at post-treatment, favouring therapist-supported ICBT over a waiting list, attention, information, or online discussion group only. Similarly, the SMD for disorder-specific symptoms at post-treatment (22 studies, 1573 participants; SMD -1.12, 95% CI -1.39 to -0.85) and general anxiety symptoms at post-treatment (14 studies, 1004 participants; SMD -0.79, 95% CI -1.10 to -0.48) favoured therapist-supported ICBT. The quality of the evidence for both outcomes was low.One study compared unguided CBT to therapist-supported ICBT for clinically important improvement in anxiety at post-treatment, showing no difference in outcome between treatments (54 participants; very low quality evidence). At post-treatment there were no clear differences between unguided CBT and therapist-supported ICBT for disorder-specific anxiety symptoms (4 studies, 253 participants; SMD -0.24, 95% CI -0.69 to 0.21; low quality evidence) or general anxiety symptoms (two studies, 138 participants; SMD 0.28, 95% CI -2.21 to 2.78; low quality evidence).Compared to face-to-face CBT, therapist-supported ICBT showed no significant differences in clinically important improvement in anxiety at post-treatment (4 studies, 365 participants; RR 1.09, 95% CI 0.89 to 1.34; moderate quality evidence). There were also no clear differences between face-to-face and therapist supported ICBT for disorder-specific anxiety symptoms at post-treatment (6 studies, 424 participants; SMD 0.09, 95% CI -0.26 to 0.43; low quality evidence) or general anxiety symptoms at post-treatment (5 studies, 317 participants; SMD 0.17, 95% CI -0.35 to 0.69; low quality evidence).Overall, risk of bias in included studies was low or unclear for most domains. However, due to the nature of psychosocial intervention trials, blinding of participants and personnel, and outcome assessment tended to have a high risk of bias. Heterogeneity across a number of the meta-analyses was substantial, some was explained by type of anxiety disorder or may be meta-analytic measurement artefact due to combining many assessment measures. Adverse events were rarely reported.

AUTHORS' CONCLUSIONS

Therapist-supported ICBT appears to be an efficacious treatment for anxiety in adults. The evidence comparing therapist-supported ICBT to waiting list, attention, information, or online discussion group only control was low to moderate quality, the evidence comparing therapist-supported ICBT to unguided ICBT was low to very low quality, and comparisons of therapist-supported ICBT to face-to-face CBT was low to moderate quality.

The evidence suggests that therapist-supported ICBT may not be significantly different from face-to-face CBT in reducing anxiety. Future research should involve equivalence trials comparing ICBT and face-to-face CBT, examine the importance of the role of the therapist in ICBT, and include effectiveness trials of ICBT in real-world settings. A timely update to this review is needed given the fast pace of this area of research.

Efficacy of an internet-based cognitive-behavioral intervention for long-term survivors of pediatric cancer: a pilot study

PURPOSE

Long-term survivors of pediatric cancer have an increased risk of post-traumatic stress symptoms (PTSS) and dysfunctional anxiety. However, there is a lack of evidence-based psychotherapy tailored to the needs of this target group. In this single-arm pilot study, an Internet-based psychological intervention ("Onco-STEP") for adolescent and young adult survivors was developed, and its efficacy in reducing PTSS and anxiety was evaluated.

METHODS

Former patients of pediatric cancer older than 15 years manifesting clinically relevant PTSS or anxiety were eligible. The cognitive-behavioral treatment consists of ten writing sessions and comprises two modules: the first aiming to reprocess the traumatic cancer-related experiences and the second aiming to build coping strategies with current cancer-related fears. Treatment was delivered via written messages on a secure Internet platform. Outcomes were assessed by the Post-traumatic Stress Diagnostic Scale, the Hospital Anxiety and Depression Scale, and the Fear of Progression/Relapse Questionnaire.

RESULTS

A total of 20 participants completed the intervention (mean age 27.3 ± 4.8 years at study; 13.8 ± 4.7 years since diagnosis; 70 % female). PTSS, anxiety, and fear of progression/relapse significantly declined at the end of the intervention, with pre-post effect sizes of 0.63, 0.74, and 0.48. In addition, we found a significant decrease in symptoms of depression. Except for the improvement in depression, all effects were sustained 3 months after the end of treatment.

CONCLUSIONS

The results show that the intervention is efficacious in reducing symptoms of post-traumatic stress and anxiety. Onco-STEP is a promising new way to treat young adult long-term survivors of pediatric cancer with late psychological effects. Future efforts need to focus on investigating specific evidence of the intervention in a randomized controlled trial.

Internet-based cognitive bias modification of interpretations in patients with anxiety disorders: a randomised controlled trial

BACKGROUND AND OBJECTIVES

Previous research suggests that negative interpretation biases stimulate anxiety. As patients with an anxiety disorder tend to interpret ambiguous information negatively, it was hypothesised that training more positive interpretations reduces negative interpretation biases and emotional problems.

METHODS

In a randomised, double-blind placebo-controlled trial, patients with different anxiety disorders were trained online over eight days to either generate positive interpretations of ambiguous social scenarios (n = 18) or to generate 50% positive and 50% negative interpretations in the placebo control condition (n = 18) (Study 1).

RESULTS

Positively trained patients made more positive interpretations and less negative ones than control patients. This training was followed by a decrease in anxiety, depression, and general psychological distress, but this effect was also observed in the control group. To get a better understanding of these unexpected results, we tested a 100% neutral placebo control group (Study 2, n = 19); now the scenarios described neutral, non-emotional situations and no valenced interpretations were generated. The results from this neutral group were comparable to the effects from the other control group.

LIMITATIONS

An advantage, but potentially also a disadvantage of the study is that CBM-I training was performed online with less control over the procedures and setting. In addition, the scenarios were not matched to the specific concerns of each patient and the training sessions were performed in close proximity to one another.

CONCLUSIONS

Compared to both control conditions, CBM-I had superior effects on interpretations, but not on emotions. The current findings showed the boundary conditions for CBM-I.
