Long-term efficacy of brief psychological treatments for common mental disorders in Myanmar refugees in Malaysia: 12-month follow-up of a randomized, active-controlled trial of integrative adapt therapy v. cognitive behavioral therapy

BACKGROUND

Long-term efficacy of brief psychotherapies for refugees in low-resource settings is insufficiently understood. Integrative adapt therapy (IAT) is a scalable treatment addressing refugee-specific psychosocial challenges.

METHODS

We report 12-month post-treatment data from a single-blind, active-controlled trial (October 2017-August 2019) where 327 Myanmar refugees in Malaysia were assigned to either six sessions of IAT (n = 164) or cognitive behavioral treatment (CBT) (n = 163). Primary outcomes were posttraumatic stress disorder (PTSD), depression, anxiety, and persistent complex bereavement disorder (PCBD) symptom scores at treatment end and 12-month post-treatment. Secondary outcome was functional impairment.

RESULTS

282 (86.2%) participants were retained at 12-month follow-up. For both groups, large treatment effects for common mental disorders (CMD) symptoms were maintained at 12-month post-treatment compared to baseline (d = 0.75-1.13). Although participants in IAT had greater symptom reductions and larger effect sizes than CBT participants for all CMDs at treatment end, there were no significant differences between treatment arms at 12-month post-treatment for PTSD [mean difference: -0.9, 95% CI (-2.5 to 0.6), p = 0.25], depression [mean difference: 0.1, 95% CI (-0.6 to 0.7), p = 0.89), anxiety [mean difference: -0.4, 95% CI (-1.4 to 0.6), p = 0.46], and PCBD [mean difference: -0.6, 95% CI (-3.1 to 1.9), p = 0.65]. CBT participants showed greater improvement in functioning than IAT participants at 12-month post-treatment [mean difference: -2.5, 95% CI (-4.7 to -0.3], p = 0.03]. No adverse effects were recorded for either therapy.

CONCLUSIONS

Both IAT and CBT showed sustained treatment gains for CMD symptoms amongst refugees over the 12-month period.

Cognitive Processing Therapy Versus Medication for the Treatment of Comorbid Substance Use Disorder and Post-Traumatic Stress Disorder in Egyptian patients (Randomized Clinical Trial)

"Earlier research has established that posttraumatic stress disorder (PTSD) and substance use disorder (SUD) frequently coexist. Aims: Cognitive Processing Therapy was compared to Sertraline and a placebo in an RCT for treating patients with comorbid SUD and PTSD. Methods: 150 patients with SUD and PTSD were interviewed by clinicians and asked to fill out the Clinician-Administered PTSD Scale (CAPS-5), Posttraumatic Stress Disorder Checklist (PCL-5), Beck Depression Inventory (BDI-II), Timeline Follow Back Interview (TLFB), and Brief Addiction Monitor (BAM). Patients were randomly assigned to the following conditions: CPT (n=50), Sertraline (n=50), or Placebo (n=50). Pretreatment, posttreatment, six and, twelve-month follow-up assessments were conducted. Results: When compared to the sertraline group, CPT resulted in much higher reductions in CAPS scores at posttreatment assessment (d=0.93, p < .000). When compared to the control group, CPT considerably reduced PTSD symptoms (the effect size, d=1.9, p < .000). Sertraline resulted in many significant decreases in CAPS when compared to control groups (the effect size , d=1.11, p<.000). At posttreatment, SUD and depression severity were significantly reduced in both CPT and Sertraline groups. After six and twelve months of follow-up, these differences persisted. Conclusion: Comparatively to the control group, CPT and Sertraline significantly decreased PTSD, SUD, and depression."

Psychological Interventions for Survivors of Intimate Partner Violence in Humanitarian Settings: An Overview of the Evidence and Implementation Considerations

This paper provides an analytical overview of different types of psychological interventions that have demonstrated efficacy in low-income and/or humanitarian settings and points to special considerations that may be needed if used with women who have been subjected to gender-based violence (GBV). This paper reviews diverse therapeutic modalities and contrasts them across several domains, including their conventional use and principles; their documented use and efficacy in humanitarian settings; any special considerations or modifications necessary for GBV-affected clients; and any additional resources or implementation concerns when working in low-income contexts. By examining the evidence base of multiple interventions, we hope to provide clinicians and GBV-prevention advocates with an overview of tools/approaches to provide survivor-centered, trauma-informed responses to GBV survivors. This analysis responds to the growing recognition that gender-based violence, in particular intimate partner violence and sexual violence, is strongly associated with mental health problems, including anxiety, depression, and post-traumatic stress. This is likely to be exacerbated in humanitarian contexts, where people often experience multiple and intersecting traumatic experiences. The need for mental health services in these settings is increasingly recognized, and a growing number of psychological interventions have been shown to be effective when delivered by lay providers and in humanitarian settings.

Primary-level worker interventions for the care of people living with mental disorders and distress in low- and middle-income countries

BACKGROUND

Community-based primary-level workers (PWs) are an important strategy for addressing gaps in mental health service delivery in low- and middle-income countries.  OBJECTIVES: To evaluate the effectiveness of PW-led treatments for persons with mental health symptoms in LMICs, compared to usual care.  SEARCH METHODS: MEDLINE, Embase, CENTRAL, ClinicalTrials.gov, ICTRP, reference lists (to 20 June 2019).   SELECTION CRITERIA: Randomised trials of PW-led or collaborative-care interventions treating people with mental health symptoms or their carers in LMICs.  PWs included: primary health professionals (PHPs), lay health workers (LHWs), community non-health professionals (CPs).  DATA COLLECTION AND ANALYSIS: Seven conditions were identified apriori and analysed by disorder and PW examining recovery, prevalence, symptom change, quality-of-life (QOL), functioning, service use (SU), and adverse events (AEs).  Risk ratios (RRs) were used for dichotomous outcomes; mean difference (MDs), standardised mean differences (SMDs), or mean change differences (MCDs) for continuous outcomes.  For SMDs, 0.20 to 0.49 represented small, 0.50 to 0.79 moderate, and ≥0.80 large clinical effects.  Analysis timepoints: T1 (<1 month), T2 (1-6 months), T3 ( >6 months) post-intervention.  MAIN RESULTS: Description of studies 95 trials (72 new since 2013) from 30 LMICs (25 trials from 13 LICs).  Risk of bias Most common: detection bias, attrition bias (efficacy), insufficient protection against contamination.  Intervention effects *Unless indicated, comparisons were usual care at T2.  "Probably", "may", or "uncertain" indicates "moderate", "low," or "very low" certainty evidence.   Adults with common mental disorders (CMDs) LHW-led interventions a. may increase recovery (2 trials, 308 participants; RR 1.29, 95%CI 1.06 to 1.56); b. may reduce prevalence (2 trials, 479 participants; RR 0.42, 95%CI 0.18 to 0.96); c. may reduce symptoms (4 trials, 798 participants; SMD -0.59, 95%CI -1.01 to -0.16); d. may improve QOL (1 trial, 521 participants; SMD 0.51, 95%CI 0.34 to 0.69); e. may slightly reduce functional impairment (3 trials, 1399 participants; SMD -0.47, 95%CI -0.8 to -0.15); f. may reduce AEs (risk of suicide ideation/attempts); g. may have uncertain effects on SU.

AUTHORS' CONCLUSIONS

PW-led interventions show promising benefits in improving outcomes for CMDs, PND, PTS, harmful alcohol/substance use, and dementia carers in LMICs.

The effectiveness of adapted psychological interventions for people from ethnic minority groups: A systematic review and conceptual typology

This review assessed the efficacy of adapted psychological interventions for Black and minority ethnic (BME) groups. A conceptual typology was developed based on adaptations reported in the literature, drawing on the common factors model, competence frameworks and distinctions between types of cultural adaptations. These distinctions were used to explore the efficacy of different adaptations in improving symptoms of a range of mental health problems for minority groups. Bibliographic searches of MEDLINE, Embase, PsycINFO, HMIC, ASSIA, CENTRAL, CDSR and CINAHL spanned the period from 1965 to December 2020. Adaptations to interventions were categorised: i) treatment specific: therapist-related, ii) treatment-specific: content-related and iii) organisation-specific. Meta-analyses of RCTs found a significant effect on symptom reduction when adapted interventions were compared to non-adapted active treatments (K = 30, Hedge's g = -0.43 [95% CI: -0.61, -0.25], p < .001). Studies often incorporated multiple adaptations, limiting the exploration of the comparative effectiveness of different adaptation types, although inclusion of organisation-specific adaptations may be associated with greater benefits. Future research, practitioner training and treatment and service development pertaining to adapted care for minority groups may benefit from adopting the conceptual typology described.

Feasibility and acceptability of brief individual interpersonal psychotherapy among university students with mental distress in Ethiopia

Background

The prevalence of mental distress among university students in low- and middle-income countries (LMICs) is increasing; however, the majority do not receive evidence-based psychological intervention. This calls for the provision of culturally adapted psychological therapy in higher education institutions in LMICs. The aim of this pilot study is to evaluate the feasibility and acceptability of Interpersonal Psychotherapy adapted for Ethiopia (IPT-E) among Wolaita Sodo University students and to assess the preliminary outcomes of IPT-E in reducing symptoms of mental distress and in improving functioning.

Methods

We used a quasi-experimental single-group pre-post-test study design. As indicators of feasibility of IPT-E, we used consent, treatment completion and attrition. We used Client Satisfaction Questionnaire and semi-structured interview to measure the acceptability of the intervention, self-reporting IPT-E checklist to assess treatment adherence and World Health Organization Disability Assessment and Self-Reporting Questionnaire-20 tools to assess functional impairment and mental distress, respectively. We used percentage, frequency, mean and standard deviation to summarize the demographic variables, feasibility and acceptability of IPT-E. We analyzed changes from pre- to post-tests of mental distress and functioning results using paired t-test and Wilcoxon signed-rank tests. Independent sample t-test and one way-ANOVA used to assess the difference in mean score of in demographic variables at baseline and eight weeks. The qualitative data was analyzed with the support of open code 4.02.

Results

IPT-E was feasible (consent rate = 100%; completion rate = 92.31%; attrition rate = 7.69%; mean score of the sessions = 8 and mode of the session = 8). The total mean score of treatment satisfaction was 27.83 (SD = 4.47). After the delivery of IPT-E, symptoms of mental distress were decreased, functioning was improved and therapist adherence to the treatment model was 100% (i.e. treatment delivered according to the IPT-E guideline).

Conclusion

IPT-E was feasible and acceptable to treat university students with mental distress in low-income country setting. The preliminary results also suggest promising viability of IPT-E in higher education institutions of low-income country setting for students with symptoms of anxiety and depression.

Lay-delivered talk therapies for adults affected by humanitarian crises in low- and middle-income countries

BACKGROUND

Published by the World Health Organization (WHO) and United Nations High Commissioner for Refugees (UNHCR) in 2015, the mental health Gap Action Programme Humanitarian Intervention Guide (mhGAP-HIG) recommends brief versions of structured psychological interventions for people experiencing symptoms of common mental disorders (CMDs). mhGAP-HIG acknowledges a growing body of evidence suggesting these interventions can be delivered by lay workers to people affected by humanitarian crises in low- and middle-income countries (LMICs). However, there has not yet been a systematic review and synthesis of this evidence. This paper reports the results of a systematic review of qualitative, quantitative, and mixed-methods studies assessing the implementation and/or effectiveness of talk therapies for CMDs when provided by lay workers in LMICs to adults who have survived or are currently living in humanitarian situations.

METHODS

Seven electronic databases were searched: MEDLINE, Embase, PsycINFO, PsycEXTRA, Global Health, Cochrane Library, and ClinicalTrials.gov . We also hand-searched the contents pages of three academic journals, reference lists of 30 systematic reviews, and online resource directories of two mental health networks. A preliminary list of included studies was circulated to topical experts for review, and all included studies were backward and forward searched. All titles, abstracts, and full-texts were independently double-screened. Quality appraisal and data extraction were carried out by a single reviewer and checked by a second reviewer, using standardised tools. Any disagreements were discussed and referred to a third reviewer as needed.

RESULTS

We identified 23 unique studies and carried out a narrative synthesis of patient and implementation outcome data. Every evaluation of the effectiveness of lay-delivered talk therapies for adults affected by humanitarian crises in LMICs showed some treatment effect for at least one CMD, and often multiple CMDs. Implementation research generally found these interventions to be acceptable, appropriate and feasible to implement, with good fidelity to manualised therapies.

CONCLUSION

Although results are promising, particularly for individually-delivered talk therapies based on cognitive behavioural therapy techniques, there is a high degree of heterogeneity in this literature. We make several recommendations on how to improve the quality and generalisability of research on this topic, to facilitate further evidence synthesis.

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.

Psychological and pharmacological interventions for posttraumatic stress disorder and comorbid mental health problems following complex traumatic events: Systematic review and component network meta-analysis

BACKGROUND

Complex traumatic events associated with armed conflict, forcible displacement, childhood sexual abuse, and domestic violence are increasingly prevalent. People exposed to complex traumatic events are at risk of not only posttraumatic stress disorder (PTSD) but also other mental health comorbidities. Whereas evidence-based psychological and pharmacological treatments are effective for single-event PTSD, it is not known if people who have experienced complex traumatic events can benefit and tolerate these commonly available treatments. Furthermore, it is not known which components of psychological interventions are most effective for managing PTSD in this population. We performed a systematic review and component network meta-analysis to assess the effectiveness of psychological and pharmacological interventions for managing mental health problems in people exposed to complex traumatic events.

METHODS AND FINDINGS

We searched CINAHL, Cochrane Central Register of Controlled Trials, EMBASE, International Pharmaceutical Abstracts, MEDLINE, Published International Literature on Traumatic Stress, PsycINFO, and Science Citation Index for randomised controlled trials (RCTs) and non-RCTs of psychological and pharmacological treatments for PTSD symptoms in people exposed to complex traumatic events, published up to 25 October 2019. We adopted a nondiagnostic approach and included studies of adults who have experienced complex trauma. Complex-trauma subgroups included veterans; childhood sexual abuse; war-affected; refugees; and domestic violence. The primary outcome was reduction in PTSD symptoms. Secondary outcomes were depressive and anxiety symptoms, quality of life, sleep quality, and positive and negative affect. We included 116 studies, of which 50 were conducted in hospital settings, 24 were delivered in community settings, seven were delivered in military clinics for veterans or active military personnel, five were conducted in refugee camps, four used remote delivery via web-based or telephone platforms, four were conducted in specialist trauma clinics, two were delivered in home settings, and two were delivered in primary care clinics; clinical setting was not reported in 17 studies. Ninety-four RCTs, for a total of 6,158 participants, were included in meta-analyses across the primary and secondary outcomes; 18 RCTs for a total of 933 participants were included in the component network meta-analysis. The mean age of participants in the included RCTs was 42.6 ± 9.3 years, and 42% were male. Nine non-RCTs were included. The mean age of participants in the non-RCTs was 40.6 ± 9.4 years, and 47% were male. The average length of follow-up across all included studies at posttreatment for the primary outcome was 11.5 weeks. The pairwise meta-analysis showed that psychological interventions reduce PTSD symptoms more than inactive control (k = 46; n = 3,389; standardised mean difference [SMD] = -0.82, 95% confidence interval [CI] -1.02 to -0.63) and active control (k-9; n = 662; SMD = -0.35, 95% CI -0.56 to -0.14) at posttreatment and also compared with inactive control at 6-month follow-up (k = 10; n = 738; SMD = -0.45, 95% CI -0.82 to -0.08). Psychological interventions reduced depressive symptoms (k = 31; n = 2,075; SMD = -0.87, 95% CI -1.11 to -0.63; I2 = 82.7%, p = 0.000) and anxiety (k = 15; n = 1,395; SMD = -1.03, 95% CI -1.44 to -0.61; p = 0.000) at posttreatment compared with inactive control. Sleep quality was significantly improved at posttreatment by psychological interventions compared with inactive control (k = 3; n = 111; SMD = -1.00, 95% CI -1.49 to -0.51; p = 0.245). There were no significant differences between psychological interventions and inactive control group at posttreatment for quality of life (k = 6; n = 401; SMD = 0.33, 95% CI -0.01 to 0.66; p = 0.021). Antipsychotic medicine (k = 5; n = 364; SMD = -0.45; -0.85 to -0.05; p = 0.085) and prazosin (k = 3; n = 110; SMD = -0.52; -1.03 to -0.02; p = 0.182) were effective in reducing PTSD symptoms. Phase-based psychological interventions that included skills-based strategies along with trauma-focused strategies were the most promising interventions for emotional dysregulation and interpersonal problems. Compared with pharmacological interventions, we observed that psychological interventions were associated with greater reductions in PTSD and depression symptoms and improved sleep quality. Sensitivity analysis showed that psychological interventions were acceptable with lower dropout, even in studies rated at low risk of attrition bias. Trauma-focused psychological interventions were superior to non-trauma-focused interventions across trauma subgroups for PTSD symptoms, but effects among veterans and war-affected populations were significantly reduced. The network meta-analysis showed that multicomponent interventions that included cognitive restructuring and imaginal exposure were the most effective for reducing PTSD symptoms (k = 17; n = 1,077; mean difference = -37.95, 95% CI -60.84 to -15.16). Our use of a non-diagnostic inclusion strategy may have overlooked certain complex-trauma populations with severe and enduring mental health comorbidities. Additionally, the relative contribution of skills-based intervention components was not feasibly evaluated in the network meta-analysis.

CONCLUSIONS

In this systematic review and meta-analysis, we observed that trauma-focused psychological interventions are effective for managing mental health problems and comorbidities in people exposed to complex trauma. Multicomponent interventions, which can include phase-based approaches, were the most effective treatment package for managing PTSD in complex trauma. Establishing optimal ways to deliver multicomponent psychological interventions for people exposed to complex traumatic events is a research and clinical priority.

Migrant Women-experiences from the Mediterranean Region

Introduction:

The phenomenon of migration is characterized and influenced by a number of different variables; and the different stages of journey are related to different levels and types of psychological distress. Women, in particular, are exposed to further specific risks during migration.

Aim:

To determine the factors that affect the psychological health of migrant women during the different stages of the migration journey.

Methods:

We provide a narrative review of the literature around the experiences of women during migration process, with a geographical focus on women migrating to the Mediterranean area.

Results:

Little data is currently available on the burden of mental health disorders for female migrants. Most studies about the mental health status of migrants were not gender-disaggregated or focused specifically on migrant women’s experiences of violence. Sexual and Gender-Based Violence (SGBV) was found to be a common risk factor faced by all the women who leave their native country to migrate to other countries.

Conclusion:

Despite the importance of the issue and the gender-specific variables related to the experience of migrant women, few studies have looked specifically at psychological variables and mental health status in the female migrant population. It is crucial that future studies are conducted around female migration, violence towards women, and women’s mental health, in order to provide an evidence-base for promoting adequate policies and prevention/treatment programs for women.

Understanding Supporting and Hindering Factors in Community-Based Psychotherapy for Refugees: A Realist-Informed Systematic Review

Culture, tradition, structural violence, and mental health-related stigma play a major role in global mental health for refugees. Our aim was to understand what factors determine the success or failure of community-based psychotherapy for trauma-affected refugees and discuss implications for primary health care programs. Using a systematic realist-informed approach, we searched five databases from 2000 to 2018. Two reviewers independently selected RCTs for inclusion, and we contacted authors to obtain therapy training manuals. Fifteen articles and 11 training manuals met our inclusion criteria. Factors that improved symptoms of depression, anxiety, and PTSD included providing culturally adapted care in a migrant-sensitive setting, giving a role to other clinical staff (task-shifting), and intervention intensity. Precarious asylum status, constraining program monitoring requirements, and diverse socio-cultural and gender needs within a setting may reduce the effectiveness of the program. Primary care programs may enable community based mental health care and may reduce mental health-related stigma for refugees and other migrants. More research is needed on the cultural constructs of distress, programs delivered in primary care, and the role of cultural and language interpretation services in mental health care.

Interpersonal Psychotherapy: A Scoping Review and Historical Perspective (1974-2017)

BACKGROUND

Interpersonal Psychotherapy (IPT) is an affect- and relationally focused, time-limited treatment supported by research spanning >4 decades. IPT focuses on stressful interpersonal experiences of loss, life changes, disputes, and social isolation. It emphasizes the role of relationships in recovery. This scoping review describes, within a historical perspective, IPT's evolution as an evidence-supported treatment of psychiatric disorders.

METHODS

English-language publications (n = 1119) identified via EMBASE, MEDLINE, PsycINFO, and Web of Science databases (1974-2017), augmented with manual reference searches, were coded for clinical focus, population demographics, format, setting, publication type, and research type. Quantitative and qualitative analyses identified IPT publications' characteristics and trends over four epochs of psychotherapy research.

RESULTS

IPT literature primarily focused on depression (n = 772 articles; 69%), eating disorders (n = 135; 12%), anxiety disorders (n = 68; 6%), and bipolar disorder (n = 44; 4%), with rising publication rates and numbers of well-conducted randomized, controlled trials over time, justifying inclusion in consensus treatment guidelines. Research trends shifted from efficacy trials to effectiveness studies and population-based dissemination initiatives. Process research examined correlates of improvement and efficacy moderators. Innovations included global initiatives, prevention trials, and digital, web-based training and treatment.

CONCLUSION

Sparked by clinical innovations and scientific advances, IPT has evolved as an effective treatment of psychiatric disorders across the lifespan for diverse patients, including underserved clinical populations. Future research to elucidate mechanisms of change, improve access, and adapt to changing frameworks of psychopathology and treatment planning is needed. IPT addresses the universal centrality of relationships to mental health, which is as relevant today as it was over 40 years ago.

Psychological interventions for posttraumatic stress disorder and depression in refugees: A meta-analysis of randomized controlled trials

Millions of refugees around the globe suffer from posttraumatic stress disorder (PTSD) and/or depression. We conducted a meta-analysis of randomized controlled trials (RCTs) to determine the efficacy of psychological interventions for PTSD and/or depression in refugees. The meta-analysis was registered on the PROSPERO database (CRD42017071384). A search using the Medline, PsycINFO, and PILOTS databases was conducted in January 2019, resulting in 17 RCTs, of which 14 were conducted with adult refugees (1,108 participants) and 3 with young refugees (<18 years; 151 participants). Further inclusion criteria were at least 10 participants completing an active psychological intervention for PTSD, depression, or both and less than 50% of participants receiving concurrent psychotropic drugs. Random effects models showed that active interventions for adult PTSD yielded a medium to large aggregated effect size (g = 0.77; 95% confidence interval [CI] [0.26, 1.28]) at posttreatment when compared with passive and active control conditions. Active interventions for adult depression also produced large controlled effect sizes at posttreatment (g = 0.82; 95% CI [0.24, 1.40]). The effects appeared to persist over the average follow-up period of 6 months. The findings suggest that psychological interventions can effectively reduce symptoms of both PTSD and depression in adult refugees. However, the considerable heterogeneity between studies indicates that the efficacy may vary significantly. Future studies should aim to explore the substantial heterogeneity in effect sizes between studies with adult refugees. Additionally, more trials with young refugees suffering from PTSD or depression are needed to determine treatment efficacy for this population.

Efficacy of interpersonal psychotherapy for post-traumatic stress disorder: A systematic review and meta-analysis

BACKGROUND

Evidence for the efficacy of treatments for post-traumatic stress disorder (PTSD) is urgently required. This systematic review and meta-analysis examines the efficacy of interpersonal psychotherapy (IPT) in reducing the symptoms of PTSD.

METHODS

Five databases were searched from inception until November 2018 to identify randomized controlled trials (RCTs) that assessed the efficacy of IPT in patients with PTSD symptoms. The reference lists of included studies were also hand searched. A random effects model was used to estimate changes in a clinician-administered PTSD scale, or self-reported symptoms.

RESULTS

Of 509 screened abstracts, ten clinical trials (11 study arms) involving 755 patients with PTSD symptoms were included. Nine studies (10 study arms) were included in the meta-analysis. The overall standardized mean difference was -0.44 (CI: -0.69, -0.19), p = 0.0005. This represents a change in the clinically administrated PTSD Scale (CAPS) of approximately 12 points. IPT was not superior to other active controls, such as medication and non-IPT psychotherapies, but was significantly superior to passive controls, such as waiting list and educational pamphlets.

LIMITATIONS

Most studies modified the IPT protocol and did not comprehensively assess clinician fidelity to the protocol. The included studies generally had small sample sizes and were of limited quality.

CONCLUSIONS

IPT may be an effective treatment for PTSD, but clinical trials with larger sample sizes and improved methodology are required to confirm effects.

Mental health and psychosocial support programmes for adults in humanitarian emergencies: a systematic review and meta-analysis in low and middle-income countries

Background

Humanitarian emergencies are a major global health challenge with the potential to have a profound impact on people’s mental and psychological health. Effective interventions in humanitarian settings are needed to support the mental health and psychosocial needs of affected populations. To fill this gap, this systematic review synthesises evidence on the effectiveness of a wide range of mental health and psychosocial support (MHPSS) programmes delivered to adults affected by humanitarian emergencies in low and middle-income countries (LMICs).

Methods

A comprehensive search of 12 electronic databases, key websites and citation checking was undertaken in 2015 and updated in May 2018. We included controlled trials published in English from 1980. We extracted data and assessed risk of bias prior to performing a meta-analysis using random effects models. When meta-analysis was not used, we narratively described individual trial effect sizes using forest plots.

Results

Thirty-five studies were included. Overall, MHPSS programmes show benefits in improved functioning and reducing post-traumatic stress disorder. There are also indications from a limited pool of evidence that cognitive–behavioural therapy and narrative exposure therapy may improve mental health conditions. Other psychotherapy modalities also showed a positive trend in favour of MHPSS programmes for improving several mental health outcomes.

Conclusion

In addition to MHPSS programme for improving mental health outcomes in adults affected by humanitarian emergencies in LMICs, there is also a need to generate robust evidence to identify potential impact on broader social dimensions. Doing so could aid the future development of MHPSS programmes and ensure their effective implementation across different humanitarian contexts in LMICs. Future research on MHPSS programmes which focus on basic services and security, community and family programmes, their cost-effectiveness and mechanisms of impact could also strengthen the MHPSS evidence base to better inform policy and practice decision-making in humanitarian settings.

Efficacy and acceptability of psychosocial interventions in asylum seekers and refugees: systematic review and meta-analysis

AimsIn the past few years, there has been an unprecedented increase in the number of forcibly displaced migrants worldwide, of which a substantial proportion is refugees and asylum seekers. Refugees and asylum seekers may experience high levels of psychological distress, and show high rates of mental health conditions. It is therefore timely and particularly relevant to assess whether current evidence supports the provision of psychosocial interventions for this population. We conducted a systematic review and meta-analysis of randomised controlled trials (RCTs) assessing the efficacy and acceptability of psychosocial interventions compared with control conditions (treatment as usual/no treatment, waiting list, psychological placebo) aimed at reducing mental health problems in distressed refugees and asylum seekers.

METHODS

We used Cochrane procedures for conducting a systematic review and meta-analysis of RCTs. We searched for published and unpublished RCTs assessing the efficacy and acceptability of psychosocial interventions in adults and children asylum seekers and refugees with psychological distress. Post-traumatic stress disorder (PTSD), depressive and anxiety symptoms at post-intervention were the primary outcomes. Secondary outcomes include: PTSD, depressive and anxiety symptoms at follow-up, functioning, quality of life and dropouts due to any reason.

RESULTS

We included 26 studies with 1959 participants. Meta-analysis of RCTs revealed that psychosocial interventions have a clinically significant beneficial effect on PTSD (standardised mean difference [SMD] = -0.71; 95% confidence interval [CI] -1.01 to -0.41; I2 = 83%; 95% CI 78-88; 20 studies, 1370 participants; moderate quality evidence), depression (SMD = -1.02; 95% CI -1.52 to -0.51; I2 = 89%; 95% CI 82-93; 12 studies, 844 participants; moderate quality evidence) and anxiety outcomes (SMD = -1.05; 95% CI -1.55 to -0.56; I2 = 87%; 95% CI 79-92; 11 studies, 815 participants; moderate quality evidence). This beneficial effect was maintained at 1 month or longer follow-up, which is extremely important for populations exposed to ongoing post-migration stressors. For the other secondary outcomes, we identified a non-significant trend in favour of psychosocial interventions. Most evidence supported interventions based on cognitive behavioural therapies with a trauma-focused component. Limitations of this review include the limited number of studies collected, with a relatively low total number of participants, and the limited available data for positive outcomes like functioning and quality of life.

CONCLUSIONS

Considering the epidemiological relevance of psychological distress and mental health conditions in refugees and asylum seekers, and in view of the existing data on the effectiveness of psychosocial interventions, these interventions should be routinely made available as part of the health care of distressed refugees and asylum seekers. Evidence-based guidelines and implementation packages should be developed accordingly.

Beyond PTSD and Fear-Based Conditioning: Anger-Related Responses Following Experiences of Forced Migration-A Systematic Review

Introduction: Experiences of forced migration include traumas that are interpersonal in nature, as well as ongoing emotional responses, stress, and frustration in post-migration setti ngs. Open questions exist, regarding anger/anger-like responses following experiences of persecution and ongoing stress. The aim of this study was to explore the adaptive and maladaptive underlying mechanisms of anger/anger-like responses, cultural, linguistic, and social contingencies, and possible interventions for problematic anger behavior. Method: We searched two databases (PsycINFO and PILOTS) with the following search terms: (refugee OR "asylum seek*" OR IDP OR "internal* displac*" OR "forced migra*" OR "involuntary migra*") AND anger. Findings: This search yielded 34 studies that were included in the final review. Although, anger is a moral, adaptive, and prosocial response, dysfunctional anger/anger-like responses arise from PTSD, "moral injury," complicated grief, and independent forms of anger behavior. Cultural, linguistic, and social issues also emerged from the search. Finally, considerations for treatment and intervention are discussed. Discussion: Anger responses following experiences of forced migration may require assessment beyond PTSD models currently framed by DSM and ICD. A very promising framework is the Adaptation and Development after Persecution and Trauma (ADAPT) model. Implications: Further longitudinal and epidemiological research will be necessary to continue testing the ADAPT model and to begin the process of assessing its cross-cultural coherence in other refugee populations (e.g., see Hinton et al., 2003). As anger behavior is also a societal issue, avenues for reconciliation, expression of grievances, employment, civic participation, and integration are needed.

Psychological therapies for the treatment of mental disorders in low- and middle-income countries affected by humanitarian crises

BACKGROUND

People living in humanitarian settings in low- and middle-income countries (LMICs) are exposed to a constellation of stressors that make them vulnerable to developing mental disorders. Mental disorders with a higher prevalence in these settings include post-traumatic stress disorder (PTSD) and major depressive, anxiety, somatoform (e.g. medically unexplained physical symptoms (MUPS)), and related disorders. A range of psychological therapies are used to manage symptoms of mental disorders in this population.

OBJECTIVES

To compare the effectiveness and acceptability of psychological therapies versus control conditions (wait list, treatment as usual, attention placebo, psychological placebo, or no treatment) aimed at treating people with mental disorders (PTSD and major depressive, anxiety, somatoform, and related disorders) living in LMICs affected by humanitarian crises.

SEARCH METHODS

We searched the Cochrane Common Mental Disorders Controlled Trials Register (CCMDCTR), the Cochrane Central Register of Controlled Trials (Wiley), MEDLINE (OVID), Embase (OVID), and PsycINFO (OVID), with results incorporated from searches to 3 February 2016. We also searched the World Health Organization (WHO) trials portal (ICTRP) and ClinicalTrials.gov to identify any unpublished or ongoing studies. We checked the reference lists of relevant studies and reviews.

SELECTION CRITERIA

All randomised controlled trials (RCTs) comparing psychological therapies versus control conditions (including no treatment, usual care, wait list, attention placebo, and psychological placebo) to treat adults and children with mental disorders living in LMICs affected by humanitarian crises.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane procedures for collecting data and evaluating risk of bias. We calculated standardised mean differences for continuous outcomes and risk ratios for dichotomous data, using a random-effects model. We analysed data at endpoint (zero to four weeks after therapy); at medium term (one to four months after therapy); and at long term (six months or longer). GRADE (Grades of Recommendation, Assessment, Development, and Evaluation) was used to assess the quality of evidence for post-traumatic stress disorder (PTSD), depression, anxiety and withdrawal outcomes.

MAIN RESULTS

We included 36 studies (33 RCTs) with a total of 3523 participants. Included studies were conducted in sub-Saharan Africa, the Middle East and North Africa, and Asia. Studies were implemented in response to armed conflicts; disasters triggered by natural hazards; and other types of humanitarian crises. Together, the 33 RCTs compared eight psychological treatments against a control comparator.Four studies included children and adolescents between 5 and 18 years of age. Three studies included mixed populations (two studies included participants between 12 and 25 years of age, and one study included participants between 16 and 65 years of age). Remaining studies included adult populations (18 years of age or older).Included trials compared a psychological therapy versus a control intervention (wait list in most studies; no treatment; treatment as usual). Psychological therapies were categorised mainly as cognitive-behavioural therapy (CBT) in 23 comparisons (including seven comparisons focused on narrative exposure therapy (NET), two focused on common elements treatment approach (CETA), and one focused on brief behavioural activation treatment (BA)); eye movement desensitisation and reprocessing (EMDR) in two comparisons; interpersonal psychotherapy (IPT) in three comparisons; thought field therapy (TFT) in three comparisons; and trauma or general supportive counselling in two comparisons. Although interventions were described under these categories, several psychotherapeutic elements were common to a range of therapies (i.e. psychoeducation, coping skills).In adults, psychological therapies may substantially reduce endpoint PTSD symptoms compared to control conditions (standardised mean difference (SMD) -1.07, 95% confidence interval (CI) -1.34 to -0.79; 1272 participants; 16 studies; low-quality evidence). The effect is smaller at one to four months (SMD -0.49, 95% CI -0.68 to -0.31; 1660 participants; 18 studies) and at six months (SMD -0.37, 95% CI -0.61 to -0.14; 400 participants; five studies). Psychological therapies may also substantially reduce endpoint depression symptoms compared to control conditions (SMD -0.86, 95% CI -1.06 to -0.67; 1254 participants; 14 studies; low-quality evidence). Similar to PTSD symptoms, follow-up data at one to four months showed a smaller effect on depression (SMD -0.42, 95% CI -0.63 to -0.21; 1386 participants; 16 studies). Psychological therapies may moderately reduce anxiety at endpoint (SMD -0.74, 95% CI -0.98 to -0.49; 694 participants; five studies; low-quality evidence) and at one to four months' follow-up after treatment (SMD -0.53, 95% CI -0.66 to -0.39; 969 participants; seven studies). Dropout rates are probably similar between study conditions (19.5% with control versus 19.1% with psychological therapy (RR 0.98 95% CI 0.82 to 1.16; 2930 participants; 23 studies, moderate quality evidence)).In children and adolescents, we found very low quality evidence for lower endpoint PTSD symptoms scores in psychotherapy conditions (CBT) compared to control conditions, although the confidence interval is wide (SMD -1.56, 95% CI -3.13 to 0.01; 130 participants; three studies;). No RCTs provided data on major depression or anxiety in children. The effect on withdrawal was uncertain (RR 1.87 95% CI 0.47 to 7.47; 138 participants; 3 studies, low quality evidence).We did not identify any studies that evaluated psychological treatments on (symptoms of) somatoform disorders or MUPS in LMIC humanitarian settings.

AUTHORS' CONCLUSIONS

There is low quality evidence that psychological therapies have large or moderate effects in reducing PTSD, depressive, and anxiety symptoms in adults living in humanitarian settings in LMICs. By one to four month and six month follow-up assessments treatment effects were smaller. Fewer trials were focused on children and adolescents and they provide very low quality evidence of a beneficial effect of psychological therapies in reducing PTSD symptoms at endpoint. Confidence in these findings is influenced by the risk of bias in the studies and by substantial levels of heterogeneity. More research evidence is needed, particularly for children and adolescents over longer periods of follow-up.

A Logic-Based Psychotherapy Approach to Treating Patients Which Focuses on Faultless Logical Functioning: A Case Study Method

Many clinical patients present to mental health clinics with depressive symptoms, anxiety, psychosomatic complaints, and sleeping problems. These symptoms which originated may originate from marital problems, conflictual interpersonal relationships, problems in securing work, and housing issues, among many others. These issues might interfere which underlie the difficulties that with the ability of the patients face in maintaining faultless logical reasoning (FLR) and faultless logical functioning (FLF). FLR implies to assess correctly premises, rules, and conclusions. And FLF implies assessing not only FLR, but also the circumstances, life experience, personality, events that validate a conclusion. Almost always, the symptomatology is accompanied by intense emotional changes. Clinical experience shows that a logic-based psychotherapy (LBP) approach is not practiced, and that therapists’ resort to psychopharmacotherapy or other types of psychotherapeutic approaches that are not focused on logical reasoning and, especially, logical functioning. Because of this, patients do not learn to overcome their reasoning and functioning errors. The aim of this work was to investigate how LBP works to improve the patients’ ability to think and function in a faultless logical way. This work describes the case studies of three patients. For this purpose we described the treatment of three patients. With this psychotherapeutic approach, patients gain knowledge that can then be applied not only to the issues that led them to the consultation, but also to other problems they have experienced, thus creating a learning experience and helping to prevent such patients from becoming involved in similar problematic situations. This highlights that LBP is a way of treating symptoms that interfere on some level with daily functioning. This psychotherapeutic approach is relevant for improving patients’ quality of life, and it fills a gap in the literature by describing original case analyses.

Meta-analysis of interventions for posttraumatic stress disorder and depression in adult survivors of mass violence in low- and middle-income countries

BACKGROUND

Most survivors of mass violence live in low- and middle-income countries (LMICs). We conducted a meta-analysis of randomized controlled psychotherapy trials for adult posttraumatic stress disorder (PTSD) and/or depression in LMICs.

METHODS

We included 18 clinical trials (3,058 participants), in which 25 and 18 treatment arms measured symptoms of PTSD and depression, respectively.

RESULTS

Active treatments for PTSD yielded a large aggregated pre-post effect size (g = 1.29; 95% CI = [0.99; 1.59]) and a small to medium effect size at posttreatment when compared to control conditions (g = 0.39; 95% CI = [0.24; 0.55]). Effect sizes were similar for pretreatment versus follow-up (g = 1.75; 95% CI = [1.17; 2.32]) and in comparison to waitlist at follow-up (g = 0.93; 95% CI = [0.56; 1.31]). Active treatments for depression produced large pre-post (g = 1.28; 95% CI = [0.96; 1.61]) and controlled effect sizes (posttreatment, comparison to control conditions, g = 0.86; 95% CI = [0.54; 1.18]).

CONCLUSIONS

Our findings suggest that psychological interventions can effectively reduce symptoms of PTSD and depression in LMICs. Future research needs to focus on cost-effective interventions that are likely to be disseminated to the large numbers of war survivors in LMICs.

A systematic review of psychosocial interventions for adult refugees and asylum seekers

Background: Europe is in the midst of the largest refugee migration since the Second World War; there is an urgent need to provide an updated systematic review of the current best evidence for managing mental distress in refugee populations.Aims: The aim of this review is to provide an exhaustive summary of the current literature on psychosocial interventions, both trauma- and non-trauma-focused, for refugee populations experiencing post-traumatic stress disorder (PTSD), depressive or anxiety symptoms. To produce recommendations for future research and current clinical practice.Method: Searches were conducted in PubMed, PsychINFO (Hosted by Ovid), PILOTS and Social Services Abstracts; 5305 articles were screened and 40 were included.Results: This review found medium to high quality evidence supporting the use of narrative exposure therapy (NET). A lack of culturally adapted treatments was apparent and there was less evidence to support standard cognitive behavioural therapy (CBT), Eye Movement Desensitisation and Reprocessing (EMDR) and multidisciplinary treatments.Conclusion: NET produced positive outcomes in refugees from a diverse range of backgrounds and trauma types. There is a general dearth of research in all intervention types: further research should include more "real-world" multidisciplinary interventions that better model clinical practice. Recommendations for evaluating local need, and creating a culturally sensitive workforce are discussed.

A Meta-Analysis of Cultural Adaptations of Psychological Interventions

Forehand and Kotchick (1996) issued a wake-up call to the field to develop culturally responsive interventions. Since that time, 11 meta-analyses on culturally adapted interventions have been conducted. To reconcile the differences of the previous meta- analyses, a new meta-analysis was conducted that included 13,998 participants, 95% of whom were non-European American, in 78 studies evaluating culturally adapted interventions with psychopathology outcomes. Using a random effects multilevel regression model, the overall effect size (g = 0.67, p < .001) favored the effectiveness of culturally adapted interventions over other conditions (no intervention, other interventions). There was a medium effect size favoring the effectiveness of culturally adapted interventions over unadapted versions of the same intervention (g = .52). The overall effect size was moderated by whether the study involved treatment (g = .76) vs. prevention (g = .25, p = .03) and whether the study involved specific measures of mood or anxiety symptoms (g = .76) vs. general measures of psychopathology (g = .48, p = .02). Culturally adapted interventions had 4.68 times greater odds than other conditions to produce remission from psychopathology (p < .001) in 16 studies that reported remission. There were greater effects in no intervention control designs (marginal odds ratio = 9.80) than in manualized intervention (marginal odds ratio = 3.47, p = .03) or another active, nonmanualized intervention (marginal odds ratio = 3.38, p = .04) comparison designs in remission studies. Research has yet to adequately investigate whether culturally adapted or unadapted interventions impact culture-specific psychopathology. These findings indicate a continuing need for rigor in the conceptualization and measurement of culture- specific psychopathology and in developing culturally responsive interventions.
