Prevention and promotion effects of Self Help Plus: secondary analysis of cluster randomised controlled trial data among South Sudanese refugee women in Uganda.

INTRODUCTION: Evidence-based and scalable prevention and promotion focused mental health and psychosocial support interventions are needed for conflict-affected populations in humanitarian settings. This study retrospectively assessed whether participation in Self Help Plus (SH+) versus enhanced usual care (EUC) resulted in reduced incidence of probable mental disorder and increased positive mental health and well-being post-intervention among South Sudanese refugee women in Uganda. METHODS: This study used secondary data from treatment-oriented pilot (n=50) and fully-powered cluster randomised controlled trials (cRCT)s (n=694) of SH+ versus EUC. Data from baseline and post-intervention assessments were combined. A composite latent indicator for mental health problems was generated using mental health and well-being measures included in both cRCTs. In order to assess incidence, a binary variable approximating probable mental disorder was created to exclude those with probable mental disorder from the analysis sample and as the primary prevention outcome. The promotive effects of SH+ relative to EUC were examined in the same sample by assessing subjective well-being and psychological flexibility scale scores. RESULTS: A single factor for mental health problems was identified with all factor loadings >0.30 and acceptable internal consistency (α=0.70). We excluded 161 women who met criteria for probable mental disorder at baseline. Among those with at least moderate psychological distress but without probable mental disorder at baseline and with follow-up data (n=538), the incidence of probable mental disorder at post-intervention was lower among those who participated in SH+ relative to EUC (Risk ratio =0.16, 95% CI: 0.05 to 0.53). Participation in SH+ versus EUC was also associated with increased subjective well-being (ß=2.62, 95% CI: 1.63 to 3.60) and psychological flexibility (ß=4.55, 95% CI: 2.92 to 6.18) at post-intervention assessment. CONCLUSIONS: These results support the use and further testing of SH+ as a selective and indicated prevention and promotion focused psychosocial intervention in humanitarian settings. TRIAL REGISTRATION NUMBER: ISRCTN50148022.

Self-Help Plus for refugees and asylum seekers: an individual participant data meta-analysis.

QUESTION: Refugees and asylum seekers are at high risk of mental disorders due to various stressors before, during and after forceful displacement. The WHO Self-Help Plus (SH+) intervention was developed to manage psychological distress and a broad range of mental health symptoms in vulnerable populations. This study aimed to examine the effects and moderators of SH+ compared with Enhanced Care as Usual (ECAU) in reducing depressive symptoms among refugees and asylum seekers. STUDY SELECTION AND ANALYSIS: Three randomised trials were identified with 1795 individual participant data (IPD). We performed an IPD meta-analysis to estimate the effects of SH+, primarily on depressive symptoms and second on post-traumatic stress, well-being, self-identified problems and functioning. Effects were also estimated at 5-6 months postrandomisation (midterm). FINDINGS: There was no evidence of a difference between SH+ and ECAU+ in reducing depressive symptoms at postintervention. However, SH+ had significantly larger effects among participants who were not employed (ß=1.60, 95% CI 0.20 to 3.00) and had lower mental well-being levels (ß=0.02, 95% CI 0.001 to 0.05). At midterm, SH+ was significantly more effective than ECAU in improving depressive symptoms (ß=-1.13, 95% CI -1.99 to -0.26), self-identified problems (ß=-1.56, 95% CI -2.54 to -0.59) and well-being (ß=6.22, 95% CI 1.60 to 10.90). CONCLUSIONS: Although SH+ did not differ significantly from ECAU in reducing symptoms of depression at postintervention, it did present benefits for particularly vulnerable participants (ie, unemployed and with lower mental well-being levels), and benefits were also evident at midterm follow-up. These results are promising for the use of SH+ in the management of depressive symptoms and improvement of well-being and self-identified problems among refugees and asylum seekers.

Psychological flexibility in South Sudanese female refugees in Uganda as a mechanism for change within a guided self-help intervention.

OBJECTIVE: To examine the role of psychological flexibility as a potential mediator in the relationship between involvement in a guided self-help intervention, Self-Help Plus, and psychological distress in a sample of South Sudanese refugee women living in northern Uganda. METHOD: We conducted secondary analysis of data from a cluster randomized controlled trial conducted in 2018. We used multilevel mediation modeling to explore the relationship of psychological flexibility, as measured by the Acceptance and Action Questionnaire (AAQ-II), as a mediating factor in the relationship between Self-Help Plus involvement and general psychological distress as measured by the Kessler Psychological Distress Scale-6 (K6). RESULTS: We found strong multilevel mediation of decreased K6 scores in the treatment group by AAQ-II scores (multilevel b = -3.28). A more pronounced mediation effect was discovered immediately post intervention (b = -1.09) compared to 3-month follow-up (b = -0.84). This is in line with the current literature that demonstrates the role of psychological flexibility as a primary mechanism of change in ACT-based interventions. CONCLUSIONS: Psychological flexibility is a contributing component in the theory of change for this ACT-based intervention. Identifying the core components of interventions allows for more effective adaptation and implementation of relevant services, especially in low-resource contexts.

Trajectories of psychosocial symptoms and wellbeing in asylum seekers and refugees exposed to traumatic events and resettled in Western Europe, Turkey, and Uganda.

Background: Longitudinal studies examining mental health trajectories in refugees and asylum seekers are scarce. Objectives: To investigate trajectories of psychological symptoms and wellbeing in refugees and asylum seekers, and identify factors associated with these trajectories. Method: 912 asylum seekers and refugees from the control arm of three trials in Europe (n = 229), Turkey (n = 320), and Uganda (n = 363) were included. We described trajectories of psychological symptoms and wellbeing, and used trauma exposure, age, marital status, education, and individual trial as predictors. Then, we assessed the bidirectional interactions between wellbeing and psychological symptoms, and the effect of each predictor on each outcome controlling for baseline values. Results: Symptom improvement was identified in all trials, and for wellbeing in 64.7% of participants in Europe and Turkey, versus 31.5% in Uganda. In Europe and Turkey domestic violence predicted increased symptoms at post-intervention (ß = 1.36, 95% CI 0.17-2.56), whilst murder of family members at 6-month follow-up (ß = 1.23, 95% CI 0.27-2.19). Lower wellbeing was predicted by murder of family member (ß = -1.69, 95% CI -3.06 to -0.32), having been kidnapped (ß = -1.67, 95% CI -3.19 to -0.15), close to death (ß = -1.38, 95% CI -2.70 to -0.06), and being in the host country ≥2 years (ß = -1.60, 95% CI -3.05 to -0.14). In Uganda at post-intervention, having been kidnapped predicted increased symptoms (ß = 2.11, 95% CI 0.58-3.65), and lack of shelter (ß = -2.51, 95% CI -4.44 to -0.58) and domestic violence predicted lower wellbeing (ß = -1.36, 95% CI -2.67 to -0.05). Conclusion: Many participants adapt to adversity, but contextual factors play a critical role in determining mental health trajectories.

Antecedentes: Estudios longitudinales que examinan las trayectorias de la salud mental en los refugiados y solicitantes de asilo son escasos.Objetivos: Investigar las trayectorias de los síntomas psicológicos y el bienestar en refugiados y solicitantes de asilo, e identificar factores asociados a estas trayectorias.Métodos: Se incluyeron 912 solicitantes de asilos y refugiados del brazo control de tres ensayos clínicos en Europa (n = 229), Turquía (n = 320) y Uganda (n = 363). Describimos las trayectorias psicológicas de los síntomas y el bienestar, y utilizamos la exposición traumática, la edad, el estado marital, la educación y el juicio individual como predictores. Después, evaluamos las interacciones bidireccionales entre el bienestar y los síntomas psicológicos, y el efecto de cada uno de los predictores en cada resultado controlando por los valores iniciales.Resultados: Se identificó una mejoría en los síntomas en todos los ensayos, y del bienestar en el 64.7% de los participantes en Europa y Turquía, versus el 31.5% en Uganda. En Europa y en Turquía, la violencia doméstica predijo el incremento de síntomas de después de la intervención (ß = 1.36, 95% CI 0.17 a 2.56), mientras que el homicidio de algún miembro familiar a los 6 meses de seguimiento (ß = 1.23, 95% CI 0.27 a 2.19). Un menor bienestar fue predicho por el homicidio de algún miembro de la familia (ß = −1.69, 95% CI −3.06 a −0.32), haber sido secuestrado (ß = −1.67, 95% CI −3.19 a −0.15), haber estado próximo a la muerte (ß = −1.38, 95% CI −2.70 a −0.06), y estar en el país de acogida ≥2 años (ß = −1.60, 95% CI −3.05 a −0.14). En Uganda, después de la intervención, haber sido secuestrado predijo un aumento de los síntomas (ß =2.11, 95% CI 0.58 a 3.65), y la falta de refugio (ß = −2.51, 95% CI −4.44 a −0.58) y la violencia doméstica predijo un menor bienestar (ß = −1.36, 95% CI −2.67 a −0.05).Conclusión: Muchos participantes se adaptan a la adversidad, pero los factores contextuales juegan un papel crítico en determinar las trayectorias de la salud mental.

SH+ 360: novel model for scaling up a mental health and psychosocial support programme in humanitarian settings.

We explore multi-sectoral integration as a model for scaling up evidence-based mental health and psychosocial support interventions in humanitarian settings. We introduce Self Help Plus 360, designed to support humanitarian partners across different sectors to integrate a psychosocial intervention into their programming and more holistically address population needs.

Self-help plus for refugees and asylum seekers; study protocol for a series of individual participant data meta-analyses.

Background: Refugees and asylum seekers face various stressors due to displacement and are especially vulnerable to common mental disorders. To effectively manage psychological distress in this population, innovative interventions are required. The World Health Organization (WHO) Self-Help Plus (SH+) intervention has shown promising outcomes in reducing symptoms of common mental disorders among refugees and asylum seekers. However, individual participant differences in response to SH+ remain largely unknown. The Individual Participant Data (IPD) meta-analysis synthesizes raw datasets of trials to provide cutting-edge evidence of outcomes that cannot be examined by conventional meta-analytic approaches. Objectives: This protocol outlines the methods of a series of IPD meta-analyses aimed at examining the effects and potential moderators of SH+ in (a) reducing depressive symptoms at post-intervention and (b) preventing the six-month cumulative incidence of mental disorders in refugees and asylum seekers. Method: RCTs on SH+ have been identified through WHO and all authors have agreed to share the datasets of the trials. The primary outcomes of the IPD meta-analyses are (a) reduction in depressive symptoms at post-intervention, and (b) prevention of six-month cumulative incidence of mental disorders. Secondary outcomes include post-traumatic stress disorder symptoms, well-being, functioning, quality of life, and twelve-month cumulative incidence of mental disorders. One-stage IPD meta-analyses will be performed using mixed-effects linear/logistic regression. Missing data will be handled by multiple imputation. Conclusions: These results will enrich current knowledge about the response to SH+ and will facilitate its targeted dissemination. The results of these IPD meta-analyses will be published in peer-reviewed journals.

Entre los resultados secundarios de incluyó síntomas de trastorno de estrés postraumático, bienestar, funcionamiento, calidad de vida e incidencia acumulada de trastornos de salud mental durante 12 meses. Se realizaran meta-análisis de IPD de una etapa usando regresión linear/logística de efectos mixtos. Los datos faltantes se manejaran mediante imputación múltiple.Conclusiones: Estos resultados enriquecerán el conocimiento actual sobre la respuesta a SH+ y facilitarán su diseminación en su público objetivo. Los resultados de estos meta-análisis de IPD serán publicados en revistas revisadas por pares.

Improving mental health and psychosocial wellbeing in humanitarian settings: reflections on research funded through R2HC.

Major knowledge gaps remain concerning the most effective ways to address mental health and psychosocial needs of populations affected by humanitarian crises. The Research for Health in Humanitarian Crisis (R2HC) program aims to strengthen humanitarian health practice and policy through research. As a significant portion of R2HC's research has focused on mental health and psychosocial support interventions, the program has been interested in strengthening a community of practice in this field. Following a meeting between grantees, we set out to provide an overview of the R2HC portfolio, and draw lessons learned. In this paper, we discuss the mental health and psychosocial support-focused research projects funded by R2HC; review the implications of initial findings from this research portfolio; and highlight four remaining knowledge gaps in this field. Between 2014 and 2019, R2HC funded 18 academic-practitioner partnerships focused on mental health and psychosocial support, comprising 38% of the overall portfolio (18 of 48 projects) at a value of approximately 7.2 million GBP. All projects have focused on evaluating the impact of interventions. In line with consensus-based recommendations to consider a wide range of mental health and psychosocial needs in humanitarian settings, research projects have evaluated diverse interventions. Findings so far have both challenged and confirmed widely-held assumptions about the effectiveness of mental health and psychosocial interventions in humanitarian settings. They point to the importance of building effective, sustained, and diverse partnerships between scholars, humanitarian practitioners, and funders, to ensure long-term program improvements and appropriate evidence-informed decision making. Further research needs to fill knowledge gaps regarding how to: scale-up interventions that have been found to be effective (e.g., questions related to integration across sectors, adaptation of interventions across different contexts, and optimal care systems); address neglected mental health conditions and populations (e.g., elderly, people with disabilities, sexual minorities, people with severe, pre-existing mental disorders); build on available local resources and supports (e.g., how to build on traditional, religious healing and community-wide social support practices); and ensure equity, quality, fidelity, and sustainability for interventions in real-world contexts (e.g., answering questions about how interventions from controlled studies can be transferred to more representative humanitarian contexts).

Guided self-help to reduce psychological distress in South Sudanese female refugees in Uganda: a cluster randomised trial.

BACKGROUND: Innovative solutions are required to provide mental health support at scale in low-resource humanitarian contexts. We aimed to assess the effectiveness of a facilitator-guided, group-based, self-help intervention (Self-Help Plus) to reduce psychological distress in female refugees. METHODS: We did a cluster randomised trial in rural refugee settlements in northern Uganda. Participants were female South Sudanese refugees with at least moderate levels of psychological distress (cutoff ≥5 on the Kessler 6). The intervention comprised access to usual care and five 2-h audio-recorded stress-management workshops (20-30 refugees) led by briefly trained lay facilitators, accompanied by an illustrated self-help book. Villages were randomly assigned to either intervention (Self-Help Plus or enhanced usual care) on a 1:1 basis. Within 14 villages, randomly selected households were approached. Screening of women in households continued until 20-30 eligible participants were identified per site. The primary outcome was individual psychological distress, assessed using the Kessler 6 symptom checklist 1 week before, 1 week after, and 3 months after intervention, in the intention-to-treat population. All outcomes were measured at the individual (rather than cluster) level. Secondary outcomes included personally identified problems, post-traumatic stress, depression symptoms, feelings of anger, social interactions with other ethnic groups, functional impairment, and subjective wellbeing. Assessors were masked to allocation. This trial was prospectively registered at ISRCTN, number 50148022. FINDINGS: Of 694 eligible participants (331 Self-Help Plus, 363 enhanced usual care), 613 (88%) completed all assessments. Compared with controls, we found stronger improvements for Self-Help Plus on psychological distress 3 months post intervention (ß -1·20, 95% CI -2·33 to -0·08; p=0·04; d -0·26). We also found larger improvements for Self-Help Plus 3 months post-intervention for five of eight secondary outcomes (effect size range -0·30 to -0·36). Refugees with different trauma exposure, length of time in settlements, and initial psychological distress benefited similarly. With regard to safety considerations, the independent data safety management board responded to six adverse events, and none were evaluated to be concerns in response to the intervention. INTERPRETATION: Self-Help Plus is an innovative, facilitator-guided, group-based self-help intervention that can be rapidly deployed to large numbers of participants, and resulted in meaningful reductions in psychological distress at 3 months among South Sudanese female refugees.
