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

Typology of modifications to peer support work for adults with mental health problems: systematic review

BACKGROUND

Peer support work roles are being implemented internationally, and increasingly in lower-resource settings. However, there is no framework to inform what types of modifications are needed to address local contextual and cultural aspects.

AIMS

To conduct a systematic review identifying a typology of modifications to peer support work for adults with mental health problems.

METHOD

We systematically reviewed the peer support literature following PRISMA guidelines for systematic reviews (registered on PROSPERO (International Prospective Register of Systematic Reviews) on 24 July 2018: CRD42018094832). All study designs were eligible and studies were selected according to the stated eligibility criteria and analysed with standardised critical appraisal tools. A narrative synthesis was conducted to identify types of, and rationales for modifications.

RESULTS

A total of 15 300 unique studies were identified, from which 39 studies were included with only one from a low-resource setting. Six types of modifications were identified: role expectations; initial training; type of contact; role extension; workplace support for peer support workers; and recruitment. Five rationales for modifications were identified: to provide best possible peer support; to best meet service user needs; to meet organisational needs, to maximise role clarity; and to address socioeconomic issues.

CONCLUSIONS

Peer support work is modified in both pre-planned and unplanned ways when implemented. Considering each identified modification as a candidate change will lead to a more systematic consideration of whether and how to modify peer support in different settings. Future evaluative research of modifiable versus non-modifiable components of peer support work is needed to understand the modifications needed for implementation among different mental health systems and cultural settings.

Lay-therapist-delivered, low-intensity, psychosocial intervention for refugees and asylum seekers (PROSPER): protocol for a pilot randomised controlled trial

Background

Asylum seekers and refugees (AS&Rs) experience impaired mental health and wellbeing, related to stresses in their country of origin, experiences in transit and reception on arrival, including significant barriers to accessing mainstream services. Their contact with health care is often crisis-driven and mediated through non-governmental organisations (NGOs).

Problem Management Plus (PM+) is a psychosocial intervention recommended by the World Health Organisation to address distress experienced by adults affected by humanitarian crises. We are investigating its application for the first time in a high-income country.

Methods

In a pilot randomised controlled trial (RCT), PM+ will be delivered to AS&Rs in contact with NGOs in Liverpool City Region, UK by lay therapists who have lived experience of forced migration. Following systematic review and stakeholder engagement, PM+ has been adapted to the local context, and lay therapists have been trained in its delivery.

We will assess the feasibility of conducting a three-arm RCT of five 90-min sessions of PM+, delivered individually or in groups by lay therapists to AS&Rs experiencing emotional distress and functional impairment, compared with each other and with usual support offered by local NGOs. Distress and impairment at baseline will be measured by the Hospital Anxiety and Depression Scale (HADS) and the WHO Disability Assessment Schedule (WHO-DAS). We aim to recruit 105 participants, 35 per arm.

Primary health outcomes are anxiety and depressive symptoms at 3 months, measured by HADS. Secondary outcomes include subjective wellbeing, functional status, progress on identified problems, presence of post-traumatic stress disorder and depressive disorder and service usage. Longer-term impact will be assessed at 6 months post baseline, on the same parameters.

We will assess the feasibility of conducting a full RCT in relation to the following elements: recruitment and retention of lay therapists and study participants; fidelity of delivery of PM+; and suitability of the study measures, including any linguistic or cultural barriers.

Discussion

We will use these findings to specify the parameters for a full RCT to test the effectiveness and cost-effectiveness of PM+ in reducing emotional distress and health inequalities, and improving functional ability and wellbeing, amongst asylum seekers and refugees.

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.

An Integrative Adapt Therapy for common mental health symptoms and adaptive stress amongst Rohingya, Chin, and Kachin refugees living in Malaysia: A randomized controlled trial

BACKGROUND

This randomised controlled trial (RCT) aims to compare 6-week posttreatment outcomes of an Integrative Adapt Therapy (IAT) to a Cognitive Behavioural Therapy (CBT) on common mental health symptoms and adaptive capacity amongst refugees from Myanmar. IAT is grounded on psychotherapeutic elements specific to the refugee experience.

METHODS AND FINDINGS

We conducted a single-blind RCT (October 2017 -May 2019) with Chin (39.3%), Kachin (15.7%), and Rohingya (45%) refugees living in Kuala Lumpur, Malaysia. The trial included 170 participants receiving six 45-minute weekly sessions of IAT (97.6% retention, 4 lost to follow-up) and 161 receiving a multicomponent CBT also involving six 45-minute weekly sessions (96.8% retention, 5 lost to follow-up). Participants (mean age: 30.8 years, SD = 9.6) had experienced and/or witnessed an average 10.1 types (SD = 5.9, range = 1-27) of traumatic events. We applied a single-blind design in which independent assessors of pre- and posttreatment indices were masked in relation to participants' treatment allocation status. Primary outcomes were symptom scores of Post Traumatic Stress Disorder (PTSD), Complex PTSD (CPTSD), Major Depressive Disorder (MDD), the 5 scales of the Adaptive Stress Index (ASI), and a measure of resilience (the Connor-Davidson Resilience Scale [CDRS]). Compared to CBT, an intention-to-treat analysis (n = 331) at 6-week posttreatment follow-up demonstrated greater reductions in the IAT arm for all common mental disorder (CMD) symptoms and ASI domains except for ASI-3 (injustice), as well as increases in the resilience scores. Adjusted average treatment effects assessing the differences in posttreatment scores between IAT and CBT (with baseline scores as covariates) were -0.08 (95% CI: -0.14 to -0.02, p = 0.012) for PTSD, -0.07 (95% CI: -0.14 to -0.01) for CPTSD, -0.07 for MDD (95% CI: -0.13 to -0.01, p = 0.025), 0.16 for CDRS (95% CI: 0.06-0.026, p ≤ 0.001), -0.12 (95% CI: -0.20 to -0.03, p ≤ 0.001) for ASI-1 (safety/security), -0.10 for ASI-2 (traumatic losses; 95% CI: -0.18 to -0.02, p = 0.02), -0.03 for ASI-3 (injustice; (95% CI: -0.11 to 0.06, p = 0.513), -0.12 for ASI-4 (role/identity disruptions; 95% CI: -0.21 to -0.04, p ≤ 0.001), and -0.18 for ASI-5 (existential meaning; 95% CI: -0.19 to -0.05, p ≤ 0.001). Compared to CBT, the IAT group had larger effect sizes for all indices (except for resilience) including PTSD (IAT, d = 0.93 versus CBT, d = 0.87), CPTSD (d = 1.27 versus d = 1.02), MDD (d = 1.4 versus d = 1.11), ASI-1 (d = 1.1 versus d = 0.85), ASI-2 (d = 0.81 versus d = 0.66), ASI-3 (d = 0.49 versus d = 0.42), ASI-4 (d = 0.86 versus d = 0.67), and ASI-5 (d = 0.72 versus d = 0.53). No adverse events were recorded for either therapy. Limitations include a possible allegiance effect (the authors inadvertently conveying disproportionate enthusiasm for IAT in training and supervision), cross-over effects (counsellors applying elements of one therapy in delivering the other), and the brief period of follow-up.

CONCLUSIONS

Compared to CBT, IAT showed superiority in improving mental health symptoms and adaptative stress from baseline to 6-week posttreatment. The differences in scores between IAT and CBT were modest and future studies conducted by independent research teams need to confirm the findings.

Efficacy of psychosocial interventions for mental health outcomes in low-income and middle-income countries: an umbrella review

BACKGROUND

Mental health conditions are leading causes of disability worldwide. Psychosocial interventions for these conditions might have a key role in their treatment, although applicability of findings to poor-resource settings might be a challenge. We aimed to evaluate the strength and credibility of evidence generated in low-income and middle-income countries (LMICs) on the efficacy of psychosocial interventions for various mental health outcomes.

METHODS

We did an umbrella review of meta-analyses of randomised studies done in LMICs. Literature searches were done in Medline, Embase, PsychINFO, CINAHL, Cochrane Library, and Epistemonikos from Jan 1, 2010, until May 31, 2019. Systematic reviews of randomised studies investigating the efficacy of psychosocial interventions for mental health conditions in LMICs were included. Systematic reviews of promotion, prevention, and protection interventions were excluded, because the focus was on treatment interventions only. Information on first author, year of publication, outcomes, number of included studies, and reported summary meta-analytic estimates was extracted from included meta-analyses. Summary effects were recalculated using a common metric and random-effects models. We assessed between-study heterogeneity, predictive intervals, publication bias, small-study effects, and whether the results of the observed positive studies were more than expected by chance. On the basis of these calculations, strength of associations was assessed using quantitative umbrella review criteria, and credibility of evidence using the GRADE approach. This study is registered with PROSPERO, number CRD42019135711.

FINDINGS

123 primary studies from ten systematic reviews were included. The evidence on the efficacy of psychosocial interventions in adults with depression in humanitarian settings (standardised mean difference 0·87, 95% CI 0·67-1·07; highly suggestive association, GRADE: moderate) and in adults with common mental disorders (0·49, 0·36-0·62; highly suggestive association, GRADE: moderate) was supported by the most robust evidence. Highly suggestive strength of association was found for psychosocial interventions in adults with schizophrenia for functional outcomes, in adults with depression, and in adults with post-traumatic stress disorder in humanitarian settings. In children in humanitarian settings, and in children with disruptive behaviour, psychosocial interventions were supported by suggestive evidence of efficacy.

INTERPRETATION

A relatively large amount of evidence suggests the benefit of psychosocial interventions on various mental health outcomes in LMICs. However, strength of associations and credibility of evidence were quite variable, depending on the target mental health condition, type of population and setting, and outcome of interest. This varied evidence should be considered in the development of clinical, policy, and implementation programmes in LMICs and should prompt further studies to improve the strength and credibility of the evidence base.

A brief transdiagnostic psychological intervention for Afghan asylum seekers and refugees in Austria: a randomized controlled trial

BACKGROUND

Asylum seekers and refugees are at great risk for developing mental disorders. Afghan refugees are a particularly vulnerable group with a low average education and mental health literacy level. Traumatic experiences and hardship before and during migration are predictive of mental health problems. However, post-migration living difficulties (PMLDs) also account for a large proportion of mental distress in such populations, which, critically, are not sufficiently considered in treatment protocols and research investigations. Indeed, the evidence base for the treatment of refugees and asylum seekers is sparse and limited mainly to trauma-specific treatments, where refugees may likely suffer from other mental health problems such as depression or anxiety.

METHODS/DESIGN

This trial is the first evaluation of a short-term, transdiagnostic treatment protocol for treatment-seeking Afghan refugees which addresses mental health problems and PMLDs while using an adapted version of the Problem Management Plus (PM+) protocol. Here, we will investigate the efficacy of an intervention manual with a prospective, single-center, randomized, assessor-blind, two-group trial among refugees who are on a waiting list for professional mental health treatment. Furthermore, we will investigate participants' subjective experiences with the intervention manual via in-depth interviews. One hundred twenty people will be assessed and randomly allocated to either the intervention arm or a treatment-as-usual arm. Clinical psychologists will conduct the treatment, and the sessions will take place with a Dari interpreter. The protocol consists of six 90-min sessions. The primary endpoint is the general symptom distress measure, assessed with the General Health Questionnaire 28 (GHQ-28). Secondary endpoints are the Post-Migration Living Difficulties Checklist (PMLDC), the International Trauma Questionnaire (ITQ), the World Health Organization Quality of Life Questionnaire (WHOQOL-BREF), the Psychological Outcome Profile (PSYCHLOPS), service and health care use (assessed with several items), and the Immigrant Integration Index (IPL-12).

DISCUSSION

This trial may provide substantial evidence for a brief transdiagnostic psychological intervention. Here, we intend to contribute to the treatment of mental health problems among Afghan refugees. The assessment of subjective experience with this treatment manual, as well as the evaluation of its clinical applicability, may optimize treatment acceptance and outcomes across a wide range of mental health problems among refugees.

Trauma-Informed Care and Cultural Humility in the Mental Health Care of People From Minoritized Communities

The prevalence and impact of trauma constitute a public health crisis that is complicated by the cultural heterogeneity of contemporary society and a higher rate of trauma among individuals from minoritized communities. A trauma-informed care approach can facilitate improved treatment of those who have experienced trauma, and trauma-informed care is increasingly viewed as potentially beneficial for all patients. This article outlines general principles of trauma-informed care and ways to enact it. Because the situations in which trauma arises, the ways in which it is conceptualized, and how patients respond to it are influenced by both culture and individual factors, a cultural humility approach is also described and recommended. Psychiatrists can navigate the complex terrain of cultures and social backgrounds in the clinical encounter and can promote healing when treating patients who have experienced trauma by adopting a trauma-informed care approach and an attitude of cultural humility.

A decennial review of psychotraumatology: what did we learn and where are we going?

On 6 December 2019 we start the 10th year of the European Journal of Psychotraumatogy (EJPT), a full Open Access journal on psychotrauma. This editorial is part of a special issue/collection celebrating the 10 years anniversary of the journal where we will acknowledge some of our most impactful articles of the past decade (also discussed below and marked with * in the reference list). In this editorial the editors present a decennial review of the field addressing a range of topics that are core to both the journal and to psychotraumatology as a discipline. These include neurobiological developments (genomics, neuroimaging and neuroendocrine research), forms of trauma exposure and impact across the lifespan, mass trauma and early interventions, work-related trauma, trauma in refugee populations, and the potential consequences of trauma such as PTSD or Complex PTSD, but also resilience. We address innovations in psychological, medication (enhanced) and technology-assisted treatments, mediators and moderators like social support and finally how new research methods help us to gain insights in symptom structures or to better predict symptom development or treatment success. We aimed to answer three questions 1. Where did we stand in 2010? 2. What did we learn in the past 10 years? 3. What are our knowledge gaps? We conclude with a number of recommendations concerning top priorities for the future direction of the field of psychotraumatology and correspondingly the journal.

Theoretical background, first stage development and adaptation of a novel Integrative Adapt Therapy (IAT) for refugees

AIMS

Refugees are confronted with the task of adapting to the long-term erosion of psychosocial systems and institutions that in stable societies support psychological well-being and mental health. We provide an overview of the theoretical principles and practical steps taken to develop a novel psychotherapeutic approach, Integrative Adapt Therapy (IAT), which aims to assist refugees to adapt to these changes. This paper offers the background informing ongoing trials of IAT amongst refugees from Myanmar.

METHODS

A systematic process was followed in formulating the therapy and devising a treatment manual consistent with the principles of the Adaptation and Development After Persecution and Trauma (ADAPT) model. The process of development and refinement was based on qualitative research amongst 70 refugees (ten from West Papua and 60 Rohingya from Myanmar). The therapeutic process was then piloted by trained interventionists amongst a purposively selected sample of 20 Rohingya refugees in Malaysia.

RESULTS

The final formulation of IAT represented an integration of the principles of the ADAPT model and evidence-based techniques of modern therapies in the field, including a transdiagnostic approach and the selective use of cognitive behavioural treatment elements such as problem-solving and emotional regulation techniques. The steps outlined in refining the manual are outlined in relation to work amongst West Papuan refugees, and the process of cultural and contextual modifications described during early piloting with Rohingya refugees in Malaysia.

CONCLUSIONS

IAT integrates universal principles of the ADAPT model with the particularities of the culture, history of conflict and living context of each refugee community; this synthesis of knowledge forms the basis for participants gaining insights into their personal patterns of psychosocial adaptation to the refugee experience. Participants then apply evidence-based techniques to improve their capacity to adapt to the serial psychosocial changes they have encountered in their lives as refugees. The overarching goal of IAT is to provide refugees with a coherent framework that assists in making sense of their experiences and their emotional and interpersonal reactions to the challenges they confront within the family and community context. As such, the principles of a general model (ADAPT) are used as a springboard for making concrete, manageable and meaningful life changes at the individual level, a potentially novel approach for psychosocial interventions in the field.

Feasibility, acceptability and preliminary outcomes of a mindfulness-based relapse prevention program in a naturalistic setting among treatment-seeking patients with alcohol use disorder: a prospective observational study

OBJECTIVES

Cultural differences between the USA and France led us to examine the feasibility, acceptability and preliminary efficacy data on craving, quality of life and psychological flexibility of the add-on Mindfulness-Based Relapse Prevention (MBRP) programme in alcohol use disorder (AUD) in France.

DESIGN

We conducted a prospective observational study with a 6-month follow-up.

SETTING

The study was performed in a naturalistic setting with adult outpatients from an addiction department.

PARTICIPANTS

We included all patients with a current AUD who participated in the MBRP programme (n=52). There was no non-inclusion criterion.

INTERVENTIONS

The intervention was an 8-week MBRP programme, combining elements of traditional relapse prevention cognitive behavioural therapy and mindfulness meditation training. This was an eight-session closed-group programme.

PRIMARY AND SECONDARY OUTCOME MEASURES

Primary outcomes were the number of attended treatment sessions, home practice frequency and dropout rate. Secondary outcomes were changes in craving, quality of life, psychological flexibility, drinking outcomes, depression, anxiety and mindfulness levels.

RESULTS

The average number of completed sessions was 6.6 (SD: 1.9). Most participants introduced mindfulness meditation into their everyday lives: 69% and 49% of included patients maintained formal practice at 3 and 6 months, respectively, and 80% and 64% maintained informal practice at 3 and 6 months, respectively. Most participants used mindfulness techniques to face high-risk situations (56% at 6 months). Participants reported a significant reduction in craving, days of alcohol use, depression and anxiety and an increase in mindfulness and psychological flexibility at 6 months.

CONCLUSIONS

The MBRP programme showed good acceptability and feasibility. MBRP seemed to improve craving, mindfulness and psychological flexibility. Comparative studies are needed to evaluate the programme's efficacy in AUD.

Effectiveness and cost-effectiveness of Self-Help Plus (SH+) for preventing mental disorders in refugees and asylum seekers in Europe and Turkey: study protocols for two randomised controlled trials

INTRODUCTION

This article describes two randomised controlled trials that will evaluate the effectiveness and cost-effectiveness of Self-Help Plus (SH+), a group self-help intervention developed by the WHO to reduce distress. In these trials SH+ is being tested as a preventative intervention to lower the incidence of mental disorders in asylum seekers and refugees with psychological distress resettled in Europe and Turkey.

METHODS AND ANALYSIS

Two prospective, multicentre, randomised, rater-blinded, parallel-group studies will follow participants over a period of 12 months. One trial will be conducted in Europe and one in Turkey. In each trial, 600 asylum seekers and refugees screening positive on the General Health Questionnaire (≥3), but without a formal diagnosis of any mental disorders according to the Mini International Neuropsychiatric Interview, will be randomly allocated to SH+or to enhanced treatment-as-usual. The primary outcome will be a lower incidence of mental disorders at 6 month follow-up. Secondary outcomes will include the evaluation of psychological symptoms, functioning, well-being, treatment acceptability and indicators of intervention cost-effectiveness.

ETHICS AND DISSEMINATION

The two trials received ethical clearance from the local Ethics Committees of the participating sites (seven sites), as well as from the WHO Ethics Committee. All participants will provide informed consent before screening and before study inclusion (a two-step procedure). The results of the trials will be disseminated in agreement with a dissemination plan that includes publication(s) in peer-reviewed journals and presentations at relevant national and international conferences and meetings.
