Internet-delivered psychological treatments: from innovation to implementation

Internet interventions, and in particular Internet-delivered cognitive behaviour therapy (ICBT), have existed for at least 20 years. Here we review the treatment approach and the evidence base, arguing that ICBT can be viewed as a vehicle for innovation. ICBT has been developed and tested for several psychiatric and somatic conditions, and direct comparative studies suggest that therapist-guided ICBT is more effective than a waiting list for anxiety disorders and depression, and tends to be as effective as face-to-face CBT. Studies on the possible harmful effects of ICBT are also reviewed: a significant minority of people do experience negative effects, although rates of deterioration appear similar to those reported for face-to-face treatments and lower than for control conditions. We further review studies on change mechanisms and conclude that few, if any, consistent moderators and mediators of change have been identified. A recent trend to focus on knowledge acquisition is considered, and a discussion on the possibilities and hurdles of implementing ICBT is presented. The latter includes findings suggesting that attitudes toward ICBT may not be as positive as when using modern information technology as an adjunct to face-to-face therapy (i.e., blended treatment). Finally, we discuss future directions, including the role played by technology and machine learning, blended treatment, adaptation of treatment for minorities and non-Western settings, other therapeutic approaches than ICBT (including Internet-delivered psychodynamic and interpersonal psychotherapy as well as acceptance and commitment therapy), emerging regulations, and the importance of reporting failed trials.

Long-term outcome of therapist-guided internet-based cognitive behavioural therapy for body dysmorphic disorder (BDD-NET): a naturalistic 2-year follow-up after a randomised controlled trial

OBJECTIVES

Most patients with body dysmorphic disorder (BDD) do not receive evidence-based treatment. A randomised controlled trial (RCT) has found that a therapist-guided internet-based cognitive-behavioural therapy (CBT) programme for BDD (BDD-NET) can be delivered safely via the internet with significant improvements in BDD symptom severity in the short term. The purpose of this study was to evaluate if the therapeutic gains of BDD-NET are maintained 2 years after treatment.

SETTING

Academic medical centre.

PARTICIPANTS

A naturalistic 2-year follow-up study of the 88 self-referred adult outpatients with a diagnosis of BDD that had received BDD-NET within the context of the RCT.

PRIMARY AND SECONDARY OUTCOMES

The primary outcome was the BDD-Yale-Brown Obsessive-Compulsive Scale (YBOCS). Responder status was defined as a ≥30% reduction in symptoms. Remission was defined as no longer meeting Diagnostic and Statistical Manual of Mental Disorders 5th edition criteria for BDD. Secondary outcomes included measures of depression, global functioning and quality of life.

RESULTS

The efficacy of BDD-NET was sustained long- term, with further improvements observed on the BDD-YBOCS during the follow-up period. At follow-up, 69% (95% CI 57% to 80%) were classified as responders and 56% (95% CI 43% to 69%) were in remission. Gains on depressive symptoms and global functioning were also sustained but not quality of life. A majority of participants reported that the main reason for seeking help for their BDD was the possibility to access the treatment from home.

CONCLUSION

BDD-NET is an effective treatment for BDD, and the patients' gains are maintained in the long term. BDD-NET has the potential to increase access to CBT and may lower the threshold for BDD sufferers to seek help in the first place.

[Cognitive Behavioral Therapy for Bulimia Nervosa]

Cognitive Behavioral Therapy for Bulimia Nervosa Abstract. Abstract:: Cognitive behavioural therapy for eating disorders is an evidence-based effective method for the treatment of bulimia nervosa. It is based on a multifactorial and behavioal disorder model in which causes, triggering and maintaining conditions are considered and summarized in a behavioral analysis. Symptom-oriented standard procedures are used in the therapy process. Skills such as emotion regulation, interpersonal competence and cognitive techniques are taught. The low self-esteem and body dissatisfaction are of particular importance. Finally, personal goals are worked on with the patient, taking into account individual needs.

Practitioner Review: School refusal: developments in conceptualisation and treatment since 2000

BACKGROUND

A generation has passed since the literature on the conceptualisation, assessment and treatment of school refusal was reviewed in this journal (Elliott, ). In the light of considerable gaps in the literature, identified at that time, and growing international interest, the current paper sought to identify progress subsequently made this century.

METHODS

We open with discussion of continuing conceptual uncertainty as to whether school refusal should incorporate both truancy and absenteeism marked by anxiety and distress. We then consider progress in treatment, and conclude by examining prognosis and subsequent adult functioning. In selecting intervention studies for review, our primary focus has been upon RCTS, systematic reviews and meta-analyses.

RESULTS

The literature review indicates that, since the turn of the century, there has been little substantial advance in knowledge that can guide practitioners. Many of the issues raised in the 1999 paper, in particular, conceptual confusion over this heterogeneous condition, a dearth of rigorous RCT designs, limited knowledge of underlying mechanisms and uncertainty as to the long-term effects of specific forms of intervention, are little clearer than before.

CONCLUSIONS

While several sound publications are available to guide intervention for school refusal, there is a continuing need for rigorous studies that can provide evidence to support individualised and tailored responses to an incapacitating problem with many causes and manifestations. While a multisystemic response to intervention approach is considered attractive, the practicalities of operating this across disparate professional borders are likely to present a long-term challenge.

Effectiveness of cognitive-behavioural therapy: a protocol for an overview of systematic reviews and meta-analyses

INTRODUCTION

Cognitive-behavioural therapy (CBT) is a psychological therapy that has been used to improve patient well-being across multiple mental and physical health problems. Its effectiveness has been examined in thousands of randomised control trials that have been synthesised into hundreds of systematic reviews. The aim of this overview is to map, synthesise and assess the reliability of evidence generated from these systematic reviews of the effectiveness of CBT across all health conditions, patient groups and settings.

METHODS AND ANALYSIS

We will run our search strategy, to identify systematic reviews of CBT, within the Database of Abstracts of Reviews of Effects, the Cochrane Library of Systematic Reviews, MEDLINE, Embase, PsycInfo, CINAHL, Child Development and Adolescent Studies, and OpenGrey between January 1992 and 25 April 2018. Independent reviewers will sift, perform data extraction in duplicate and assess the quality of the reviews using the Assessing the Methodological Quality of Systematic Reviews (V.2) tool. The outcomes of interest include: health-related quality of life, depression, anxiety, psychosis and physical/physiological outcomes prioritised in the individual reviews. The evidence will be mapped and synthesised where appropriate by health problem, patient subgroups, intervention type, context and outcome.

ETHICS AND DISSEMINATION

Ethical approval is not required as this is an overview of published systematic reviews. We plan to publish results in peer-reviewed journals and present at international and national academic, clinical and patient conferences.

[Irritable bowel syndrome: comorbid psychiatric disorders and psychological treatment options]

Irritable bowel syndrome is a chronic functional gastrointestinal disorder with a prevalence of 7-21%. It has a negative impact on health-related quality of life and work productivity and it is associated with increased psychological distress and mental comorbidity, like major depression disorder and generalised anxiety disorder. Due to biopsychosocial factors and the brain-gut axis playing a key role in the aetiology of the disease, the use of psychological treatments has great importance in the therapy of irritable bowel syndrome. These interventions focus on central mechanisms, like visceral sensitivity, pain amplification, hypervigilance and gastrointestinal symptom-specific anxiety. They significantly reduce damaging illness-related cognitions, the use of maladaptive coping strategies, catastrophic appraisals of bodily sensations and chronic muscle tension. The utilization of these treatments is associated with clinically significant symptom improvement and positive mental health outcomes. This review study focuses on the psychiatric comorbidity of irritable bowel syndrome and the use of evidence-based psychological therapies in the treatment of the disease. Using ScienceDirect and PubMed databases, almost 60 studies have been selected. A high number of studies investigate the efficacy of cognitive behaviour therapy and hypnotherapy with meta-analyses included. There is also growing evidence on the beneficial impacts of mindfulness-based stress reduction. Future research will need to concentrate on studying the utility of mind-body therapies such as relaxation techniques in the treatment of irritable bowel syndrome with meta-analyses on the effects of mindfulness-based interventions.

Optimal treatment for obsessive compulsive disorder: a randomized controlled feasibility study of the clinical-effectiveness and cost-effectiveness of cognitive-behavioural therapy, selective serotonin reuptake inhibitors and their combination in the management of obsessive compulsive disorder

Established treatments for obsessive compulsive disorder (OCD) include cognitive behaviour therapy (CBT) and selective serotonin reuptake inhibitor (SSRI) medication. Combined treatment may outperform monotherapy, but few studies have investigated this. A total of 49 community-based adults with OCD were randomly assigned to CBT, SSRI, or SSRI+CBT. Sertraline (50-200 mg/day) was given as the SSRI for 52 weeks. A 16-h-manualized individual CBT was delivered over 8 weeks with four follow-up sessions. Assessors were 'blinded' to treatment allocation. A preliminary health economic evaluation was conducted. At week 16, combined treatment (n=13) was associated with the largest improvement, sertraline (n=7) the next largest and CBT (n=9) the smallest on the observed case analysis. The effect size (Cohen's d) comparing the improvement in Yale Brown Obsessive Compulsive Scale on CBT versus combined treatment was -0.39 and versus sertraline was -0.27. Between 16 and 52 weeks, the greatest clinical improvement was seen with sertraline, but participant discontinuation prevented reliable analysis. Compared with sertraline, the mean costs were higher for CBT and for combined treatment. The mean Quality Adjusted Life Year scores for sertraline were 0.1823 (95% confidence interval: 0.0447-0.3199) greater than for CBT and 0.1135 (95% confidence interval: -0.0290-0.2560), greater than for combined treatment. Combined treatment appeared the most clinically effective option, especially over CBT, but the advantages over SSRI monotherapy were not sustained beyond 16 weeks. SSRI monotherapy was the most cost-effective. A definitive study can and should be conducted.

Manualised Cognitive Behaviour Therapy for Anorexia Nervosa: Use of Treatment Modules in the ANTOP Study

Standardised treatment manuals facilitate therapy planning and enhance comparability for research purposes. Within the Anorexia Nervosa Treatment of Out Patients (ANTOP) study, the largest multisite outpatient intervention trial in anorexia nervosa (AN) to date, manualised enhanced cognitive-behavioural therapy (CBT-E) was offered as one treatment modality. The manual consisted of 9 modules, of which Motivation, Nutrition, Formulation and Relapse Prevention were compulsory. Homework worksheets were provided, to ensure the transfer of therapeutic improvements to daily life. This study investigated the use of modules and worksheets in order to explore practice styles of trained therapists in the treatment of AN. This secondary analysis was based on log-sheets (n = 2604) CBT-E therapists completed after each session. Frequencies of modules and worksheets used across all sessions were calculated. Relationships, such as that between use of module and duration of illness, were examined. The most commonly used module was Motivation. In patients with longer illness duration, the module Self Esteem seemed to be particularly important. The worksheet Scales, balancing the pros and cons of AN, was prioritised by therapists. The results underline the importance of motivational work in the treatment of AN, including validating the ambivalence experienced by most AN patients. With increasing duration of illness, resource-oriented elements, such as self esteem stabilisation, should be of focus.

Do interpersonal fears mediate the association between childhood maltreatment and interpersonal skills deficits? A matched cross-sectional analysis

Objective: Childhood maltreatment, interpersonal fear and a specific kind of interpersonal skills deficit (preoperational thinking) have all been associated with persistent depressive disorder (PDD). We hypothesize that interpersonal fears mediate the association between childhood maltreatment and preoperational thinking.Method: A total of 108 matched participants have been examined cross-sectionally (31 healthy controls, 30 patients with episodic depression and 47 patients with PDD) with the following instruments: the Childhood Trauma Questionnaire (CTQ-SF), a measure of interpersonal fear (CBASP Interpersonal Questionnaire) and the Lübeck Questionnaire of Preoperational Thinking.Results: Patients with PDD reported significantly more childhood maltreatment than patients with episodic depression (d = 0.65) and healthy controls (d = 1.29). They also had more interpersonal fears (d = 0.71 and d = 2.11 respectively) and higher levels of preoperational thinking (d = 0.90 and d = 2.78 respectively). The association between childhood maltreatment and preoperational thinking was mediated through interpersonal fears.Conclusions: Our findings might have important implications for psychotherapy of PDD because they demonstrate how specific problems in social interactions can be associated with interpersonal fears that arise secondary to childhood maltreatment.

Cognitive behaviour therapy for distress in people with inflammatory bowel disease: A benchmarking study

OBJECTIVE

Anxiety and depression are common in inflammatory bowel disease (IBD) and have been linked to clinical recurrence. Previous randomized controlled trials (RCT's) have found no evidence that psychological interventions enhance outcomes for people with IBD but have recruited patients without distress. This study investigates the clinical benefits of a nonrandomized uncontrolled study of clinic based cognitive behaviour therapy (CBT) for people with IBD who had moderate-severe levels of anxiety or low mood and compares the results with a previous RCT of CBT in this population.

METHOD

Assessments were completed at baseline and end of treatment and included measures of low mood, generalized anxiety, quality of life (QOL), and symptomatic disease activity. The patient health questionnaire and generalized anxiety disorder 7 measures were the primary outcomes. Results in the form of a standardized effect size of treatment were compared with a previous RCT to consider if CBT had greater benefits for those with distress.

RESULTS

Thirty patients were deemed appropriate for CBT, and 28 accepted treatment. The results from this clinic based CBT intervention suggest statistically significant reductions in symptoms of anxiety (<0.001), low mood (<0.001), and disease activity (p < 0.01) and increases in QOL (p < 0.001). The uncontrolled effect sizes were large and superior to those found in published RCTs.

CONCLUSION

This nonrandomized uncontrolled trial of a clinic-based CBT intervention suggests that CBT may have benefits for those with moderate-severe disturbances to mood and that effect sizes can be improved by targeting those with distress. RCTs are required to establish efficacy.

Comparing Alliance in Two Cognitive-Behavioural Therapies for Adolescents With ADHD Using a Randomized Controlled Trial

Alliance is defined as the client-therapist bond and their ability to collaborate on therapeutic activities. Treatment for adolescents with ADHD is rarely studied in terms of alliance. In this study, two cognitive-behavioral treatments (CBT; one structured treatment aimed at planning skills and one less-structured solution-focused treatment, both delivered in the style of Motivational Interviewing) were compared with regard to alliance and alliance-outcome association. The influence of therapist competence on this alliance-outcome association was also evaluated. The alliance between 69 adolescents diagnosed with ADHD and their therapists was measured early in treatment, using the Therapy Process Observational Coding System for Child Psychotherapy-Alliance scale. Observer-rated therapist competence was measured using the Motivational Interviewing Treatment Integrity scale (version 3.1.1.). Outcome variables were the adolescents' reduction in planning problems and ADHD symptoms. The alliance, and, more specifically, collaboration on therapeutic activities, was significantly higher for the more structured CBT (p = .04; moderate effect size). Alliance was not related to outcome in the more structured CBT, while the alliance was positively related to the reduction in planning problems in the less structured CBT. Finally, alliance was a significant mediator between therapist competence and treatment outcome for the less-structured CBT. The clarity and structure of CBT may help facilitate alliance formation for adolescents with ADHD who often have difficulty implementing structure themselves. Therapists may need to invest more in alliance formation in less structured CBT as the alliance affects outcome. Moreover, enhancing therapist competence in less structured CBT may help improve outcomes in less structured CBT, as therapist competence may impact outcome through alliance.

First-line therapy for post-traumatic stress disorder: A systematic review of cognitive behavioural therapy and psychodynamic approaches

BACKGROUND

Despite evidence supporting cognitive behavioural therapy (CBT)-based interventions as the most effective approach for treating post-traumatic stress disorder (PTSD) in randomised control trials, alternative treatment interventions are often used in clinical practice. Psychodynamic (PDT)-based interventions are one example of such preferred approaches, this is despite comparatively limited available evidence supporting their effectiveness for treating PTSD.

AIMS

Existing research exploring effective therapeutic interventions for PTSD includes trauma-focused CBT involving exposure techniques. The present review sought to establish the treatment efficacy of CBT and PDT approaches and considers the potential impact of selecting PDT-based techniques over CBT-based techniques for the treatment of PTSD.

RESULTS

The evidence reviewed provided examples supporting PDT-based therapy as an effective treatment for PTSD, but confirmed CBT as more effective in the treatment of this particular disorder. Comparable dropout rates were reported for both treatment approaches, suggesting that relative dropout rate should not be a pivotal factor in the selection of a PDT approach over CBT for treatment of PTSD.

CONCLUSION/IMPLICATIONS

The need to routinely observe evidence-based recommendations for effective treatment of PTSD is highlighted and factors undermining practitioner engagement with CBT-based interventions for the treatment of PTSD are identified.

Patient predictors of response to cognitive behaviour therapy and schema therapy for depression

OBJECTIVE

Few studies have examined differential predictors of response to psychotherapy for depression. Greater understanding about the factors associated with therapeutic response may better enable therapists to optimise response by targeting therapy for the individual. The aim of the current exploratory study was to examine patient characteristics associated with response to cognitive behaviour therapy and schema therapy for depression.

METHODS

Participants were 100 outpatients in a clinical trial randomised to either cognitive behaviour therapy or schema therapy. Potential predictors of response examined included demographic, clinical, functioning, cognitive, personality and neuropsychological variables.

RESULTS

Individuals with chronic depression and increased levels of pre-treatment negative automatic thoughts had a poorer response to both cognitive behaviour therapy and schema therapy. A treatment type interaction was found for verbal learning and memory. Lower levels of verbal learning and memory impairment markedly impacted on response to schema therapy. This was not the case for cognitive behaviour therapy, which was more impacted if verbal learning and memory was in the moderate range.

CONCLUSION

Study findings are consistent with the Capitalisation Model suggesting that therapy that focuses on the person's strengths is more likely to contribute to a better outcome. Limitations were that participants were outpatients in a randomised controlled trial and may not be representative of other depressed samples. Examination of a variety of potential predictors was exploratory and requires replication.

Impact of confrontations by therapists on impairment and utilization of the therapeutic alliance

OBJECTIVE

Striking the balance between creating challenge through confrontation (drawing attention to discrepancies) to encourage change and offering support through the therapeutic relationship to ensure safety for patients represents a central issue for psychotherapists. The aim of the present study was to assess immediate effects of confrontations by therapists on the therapeutic alliance.

METHOD

We rated video recordings of 77 therapies to measure incidences of alliance ruptures/resolution attempts as well as confrontations by therapists. Change in the therapeutic alliance and therapy outcome were measured through questionnaires filled out by patients.

RESULTS

Confrontations were significantly associated with ruptures/resolution attempts on the micro level. Changes in the therapeutic alliance moderated the association between confrontations and alliance ruptures on the macro level: The bigger the fraction of a session containing confrontations, the larger the fraction containing ruptures, given a prior positive change in the therapeutic alliance. Therapists' use of confrontation during a resolution attempt was associated with significantly better therapy outcomes than no use of confrontation during or no resolution attempt.

CONCLUSIONS

Confrontations by therapists may temporarily impair the therapeutic alliance, but might also lead to better therapy outcomes when used to make an alliance rupture explicit as part of a resolution attempt. Clinical or methodological significance: This study provides quantitative explorations of therapists' fears and hopes regarding the use of confrontations (defined as focus on a discrepancy by the therapist). Results point to associations between confrontations and alliance ruptures, especially in the context of a secure alliance. Furthermore, resolution attempts might profit from initial confrontations regarding the relevant alliance rupture.

Treating anxiety and depression in young adults: A randomised controlled trial comparing clinician-guided versus self-guided Internet-delivered cognitive behavioural therapy

BACKGROUND

Internet-delivered cognitive behaviour therapy may increase access by young adults to evidence-based treatments for anxiety and depression.

OBJECTIVE

The aim of this study was to compare the efficacy of an Internet-delivered cognitive behaviour therapy intervention designed for adults aged 18-24 years, when delivered in clinician-guided versus self-guided formats.

DESIGN

The intervention, the Mood Mechanic Course, is a transdiagnostic treatment that simultaneously targets symptoms of anxiety and depression using cognitive and behavioural skills. The brief intervention comprised four lessons, delivered over 5 weeks. Following a brief telephone interview, young adults ( n = 191) with symptoms of anxiety and depression were randomly allocated to either (1) clinician-guided treatment ( n = 96) or (2) self-guided treatment ( n = 95).

RESULTS

At post treatment, large reductions (average improvement; clinician guided vs self-guided) were observed in symptoms of anxiety (44% vs 35%) and depression (40% vs 31%) in both groups. Significant improvements were also observed in general psychological distress (33% vs 29%), satisfaction with life (18% vs 15%) and disability (36% vs 29%). No marked or consistent differences in clinical outcomes emerged between conditions at post-treatment, at 3-month or 12-month follow-up. Satisfaction was high with both treatment formats, but slightly higher for clinician-guided treatment.

CONCLUSION

These results indicate the potential of carefully developed Internet-delivered cognitive behaviour therapy interventions for young adults with anxiety and depression provided in either self or therapist-guided format. Further large-scale research is required to determine the short- and long-term advantages and disadvantages of different models of support.

Potential mediators of improvement in painful chemotherapy-induced peripheral neuropathy via a web-based cognitive behavioural intervention

PURPOSE

Preliminary evidence suggests that a self-guided cognitive and behaviourally-based pain management intervention (PROSPECT) is effective for chronic painful chemotherapy-induced peripheral neuropathy (CIPN), but its mechanism of action is unknown. The purpose of this secondary analysis was to explore if changes in anxiety, depression, sleep-related impairment, or fatigue mediated improvements in worst pain following PROSPECT in individuals with chronic painful CIPN.

METHODS

Sixty participants were randomized to receive self-guided cognitive behavioural pain management (access for eight weeks) or treatment as usual. A seven-day worst CIPN pain diary and the PROMIS measures of anxiety, depression, fatigue, and sleep-related impairment were administered pre/posttest (eight-weeks). Causal mediation analysis was used to quantify mediators of worst pain improvement.

RESULTS

None of the hypothesized mediators had a statistically significant effect on worst pain (n=38).

IMPLICATIONS

Further research is needed to identify potential mediators of pain intensity that can be targeted by specific cognitive behavioural strategies to improve painful CIPN severity.

Weight suppression as a predictor variable in the treatment of eating disorders: A systematic review

WHAT IS KNOWN ON THE SUBJECT?: Weight suppression (WS) has been suggested to predict outcome following psychological treatment for an eating disorder (ED). Some findings are contradictory and have not been considered systematically. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: The review suggests that weight gain at post-treatment is reliably predicted by pretreatment WS, but findings regarding other outcomes (e.g., treatment dropout) are less consistent. Approximate effect sizes for observed relationships are identified, alongside support for biobehavioural theories of metabolic adaptation to weight loss. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Degree of WS at pretreatment is associated with weight gain and is important for clinicians to consider before offering treatment to patients with EDs. Patients high in WS might benefit from further support (e.g., psychoeducation) prior to beginning treatment. ABSTRACT: Introduction Weight suppression (WS-the difference between highest body weight and current body weight) has been proposed as a predictor of treatment outcome within eating disorders (EDs), although this hypothesis has not been consistently supported. Aim/Question Review the association between pretreatment WS and outcome following psychological treatment for EDs. Method A comprehensive electronic database search for published and unpublished literature from 1979 to 2017. Reference lists were also inspected. Eligibility criteria were determined according to relevant guidelines and a quality appraisal was conducted. Results Twelve studies met inclusion criteria (one was subsequently excluded based on insufficient data). Greater WS was generally associated with weight gain at post-treatment although not with other treatment outcomes. Discussion The existing evidence, with data from 1,566 participants, is summarized according to three main post-treatment outcomes: weight change; treatment completion; and symptom abstinence. Patients with disordered eating and greater WS may need to gain more weight than others during treatment to achieve good outcomes. Recommendations for future studies are provided. Implications for practice Evidence-based treatments for EDs may benefit from considering WS when planning treatment, such as further psychoeducation on weight changes. Societal interventions regarding promotion of healthy eating may also draw on these findings.

A comparison between the clinical significance and growth mixture modelling early change methods at predicting negative outcomes

Objective: Routine outcome monitoring benefits treatment by identifying potential no change and deterioration. The present study compared two methods of identifying early change and their ability to predict negative outcomes on self-report symptom and wellbeing measures. Method: 1467 voluntary day patients participated in a 10-day group Cognitive Behaviour Therapy (CBT) program and completed the symptom and wellbeing measures daily. Early change, as defined by (a) the clinical significance method and (b) longitudinal modelling, was compared on each measure. Results: Early change, as defined by the simpler clinical significance method, was superior at predicting negative outcomes than longitudinal modelling. The longitudinal modelling method failed to detect a group of deteriorated patients, and agreement between the early change methods and the final unchanged outcome was higher for the clinical significance method. Conclusions: Therapists could use the clinical significance early change method during treatment to alert them of patients at risk for negative outcomes, which in turn could allow therapists to prevent those negative outcomes from occurring.

Development of a cognitive behavioural therapy-based guided self-help intervention for adults with intellectual disability

BACKGROUND

Despite strong evidence for cognitive behaviour therapy (CBT) in treating mental health, its use, thus far, has been limited for people with intellectual disabilities. This study describes a CBT-based guided self-help (CBT-GSH) manual for individuals with intellectual disability, and focus groups explore the views of clinicians, therapists, support staff and managers.

MATERIAL AND METHODS

Using a qualitative methodology, an expert team adapted the manual. Focus groups provided feedback, followed by thematic content analysis for modifications.

RESULTS

Participants supported using the manual, with varying views about the delivery. Quality of relationships and competence of the administrator determined the best person to deliver the treatment. Heterogeneity in the intellectual disability population was a challenge to delivering manual-based interventions. Participants made suggestions about language and organization.

CONCLUSIONS

Amendments were made to the manual in line with expert feedback. An evaluation is warranted to test for feasibility, delivery, acceptability and efficacy.

Prediction of outcome in internet-delivered cognitive behaviour therapy for paediatric obsessive-compulsive disorder: A machine learning approach

BACKGROUND

There are no consistent predictors of treatment outcome in paediatric obsessive-compulsive disorder (OCD). One reason for this might be the use of suboptimal statistical methodology. Machine learning is an approach to efficiently analyse complex data. Machine learning has been widely used within other fields, but has rarely been tested in the prediction of paediatric mental health treatment outcomes.

OBJECTIVE

To test four different machine learning methods in the prediction of treatment response in a sample of paediatric OCD patients who had received Internet-delivered cognitive behaviour therapy (ICBT).

METHODS

Participants were 61 adolescents (12-17 years) who enrolled in a randomized controlled trial and received ICBT. All clinical baseline variables were used to predict strictly defined treatment response status three months after ICBT. Four machine learning algorithms were implemented. For comparison, we also employed a traditional logistic regression approach.

RESULTS

Multivariate logistic regression could not detect any significant predictors. In contrast, all four machine learning algorithms performed well in the prediction of treatment response, with 75 to 83% accuracy.

CONCLUSIONS

The results suggest that machine learning algorithms can successfully be applied to predict paediatric OCD treatment outcome. Validation studies and studies in other disorders are warranted.

Symptom fluctuations, self-esteem, and cohesion during group cognitive behaviour therapy for early psychosis

Group cohesion has been linked to positive changes in self-esteem and in symptoms during group psychotherapy in people with psychosis. These changes may be linked to changes in symptoms as fluctuations in self-esteem have been linked to symptom fluctuations.

OBJECTIVE

We aimed to determine the relationship between these three factors - group cohesion, self-esteem, and symptoms - during group cognitive behaviour therapy for psychosis (GCBTp). We hypothesized that group cohesion would precede changes in symptoms and self-esteem and that improvements in self-esteem would precede improvements in symptoms.

DESIGN

This is an uncontrolled longitudinal study recruiting from a convenience sample within two early psychosis clinics.

METHODS

Sixty-six individuals from first episode of psychosis treatment programmes participated in this study and received 24 sessions of a validated GCBTp protocol. Participants answered a brief questionnaire at the end of each session, measuring their group cohesion, self-esteem, and perception of their symptoms as worse, same, or better than usual.

RESULTS

Orthogonal polynomial contrasts for time effects were estimated with a mixed model for repeated measures with a random cluster effect and revealed a quartic trend regarding changes in symptoms over the 24 sessions. Self-esteem, symptoms, and group cohesion were strongly linked during a given session. Also, self-esteem changes predicted changes in symptoms up to two sessions later, and symptoms changes predicted self-esteem changes at the next session. Group cohesion preceded improvements in both self-esteem and symptoms; self-esteem also predicted improvements in group cohesion.

CONCLUSION

These results suggest that self-esteem and symptoms influence each other during therapy, with improvements in one leading to improvements in the other. Group cohesion also appears to be an essential prerequisite to positive changes in self-esteem and symptoms during GCBTp.

PRACTITIONER POINTS

This study emphasizes the interrelation between self-esteem improvements and symptom improvements, with improvements in one leading to improvements in the other, during group CBT for psychosis. Group cohesion, in this study, is a predictor of self-esteem and symptom improvements, suggesting that a special attention should be given to developing a strong alliance and group cohesion early on during CBT for psychosis.

The relationship between the therapeutic alliance and clinical outcomes in cognitive behaviour therapy for adults with depression: A meta-analytic review

Research consistently provides evidence for the relationship between the therapeutic alliance (TA) and outcome across various therapies and presenting problems. Depression is considered the leading cause of disability worldwide, and there is substantial evidence for the efficacy for Cognitive Behaviour Therapy (CBT) in its treatment. At present, there is lack of clarity specifically about the relationship between the TA and outcome in CBT for depression. The present review is the first meta-analytic review to explore this relationship and also considering moderators. Within a random-effects model, an overall mean effect size of r = 0.26 (95% CI [.19-.32]) was found, indicating that the TA was moderately related to outcome in CBT for depression. The mean TA-outcome correlation is consistent with existing meta-analysis that looked across a broad range of presenting problems and psychological therapies. A secondary exploratory analysis of moderators suggested the TA-outcome relationship varied according to the TA rater, where the relationship was weaker for therapist raters compared with clients and observer raters. Additionally, the results indicated that the TA-outcome relationship marginally increased over the course of CBT treatment. The results of the meta-analysis are discussed in reference to the wider body of research, methodological limitations, clinical implications, and future directions for research.

Psychosocial interventions for technological addictions

Increase in the use of technology has led to an increase in various kinds of technological addictions. A range of psychological and behavioural theories has been proposed to explain technology addictions. These include learning theories, reward-deficiency hypothesis, impulsivity, cognitive-behavioural models and social skills deficiency theories. While no particular form of psychological intervention has been suggested as being the golden standard for its treatment, the most frequently investigated approaches have been cognitive behavioural therapy (CBT) and motivational enhancement therapy. Given the need for the use of technology in daily living, controlled use has taken precedence over complete abstinence as the goal of treatment for technology addictions. Therapeutic techniques suggested for internet addiction include practicing the opposite, using external stoppers, setting goals, selective abstinence from certain applications, using cues, making personal inventories, joining support groups and family therapy interventions.

Do Acute Benefits of Interpersonal Psychotherapy for Posttraumatic Stress Disorder Endure?

OBJECTIVE

The Psychotherapies for Chronic PTSD randomised trial found that three 14-week psychotherapies acutely benefitted patients with chronic posttraumatic stress disorder (PTSD). Previous research has reported sustained follow-up benefits for prolonged exposure (PE) and relaxation therapy (RT), but few comparable data exist for interpersonal psychotherapy (IPT). We describe 3-month follow-up for acute responders to all 3 treatments.

METHOD

Acute responders, defined a priori as ≥30% improved from baseline, were reevaluated after 3-month no-treatment follow-up by independent evaluators using the Clinician-Administered PTSD Scale (CAPS).

RESULTS

Fifty of 110 initial study entrants met acute responder status at week 14. Forty-three (86%) responders entered follow-up: 23 remitters (CAPS ≤20) and 20 responders. At week 26, 27 had achieved remission status, 10 remained responders, and 6 had relapsed. Of week 14 remitters, 8 of 9 PE, all 8 IPT, and 4 of 6 RT patients remained remitted. Relapse rates were 7% (1/9) for PE, 10% (2/20) for IPT, and 33% (3/9) for RT. At week 26, PE showed greater improvement on CAPS than RT ( P = 0.048) and a trend for superiority over IPT ( P = 0.098), with no significant difference between IPT and RT. Depressive symptoms remained low during follow-up.

CONCLUSIONS

These are the first systematic data on follow-up responder status and persistence of acute treatment benefits in patients receiving individual IPT for chronic PTSD. Patients generally maintained gains across treatments, fluctuating most in RT. Study limitations include small sample size and brief follow-up interval. PTSD research should employ response and remission criteria.

Dialectical behaviour therapy for posttraumatic stress disorder related to childhood sexual abuse: a pilot study in an outpatient treatment setting

Background: Dialectical behaviour therapy for posttraumatic stress disorder (DBT-PTSD), which is tailored to treat adults with PTSD and co-occurring emotion regulation difficulties, has already demonstrated its efficacy, acceptance and safety in an inpatient treatment setting. It combines elements of DBT with trauma-focused cognitive behavioural interventions. Objective: To investigate the feasibility, acceptance and safety of DBT-PTSD in an outpatient treatment setting by therapists who were novice to the treatment, we treated 21 female patients suffering from PTSD following childhood sexual abuse (CSA) plus difficulties in emotion regulation in an uncontrolled clinical trial. Method: The Clinician Administered PTSD Symptom Scale (CAPS), the Davidson Trauma Scale (DTS), the Borderline Section of the International Personality Disorder Examination (IPDE) and the Borderline Symptom List (BSL-23) were used as primary outcomes. For secondary outcomes, depression and dissociation were assessed. Assessments were administered at pretreatment, post-treatment and six-week follow-up. Results: Improvement was significant for PTSD as well as for borderline personality symptomatology, with large pretreatment to follow-up effect sizes for completers based on the CAPS (Cohens d = 1.30), DTS (d = 1.50), IPDE (d = 1.60) and BSL-23 (d = 1.20). Conclusion: The outcome suggests that outpatient DBT-PTSD can safely be used to reduce PTSD symptoms and comorbid psychopathology in adults who have experienced CSA.
