New directions in the mental health care of migrants, including refugees-A randomized controlled trial investigating the efficacy of value-based counselling

Brief CBT-based psychological interventions to improve mental health outcomes in refugee populations: a systematic review and meta-analysis

Background: Refugees, asylum seekers, and internally displaced people experience a high burden of mental health problems owing to their experiencing traumas and stressful events.Objective: To summarise the available evidence and analyse the efficacy of brief psychological interventions (< 3 months) on improving mental health outcomes, including depression, anxiety, and post-traumatic stress disorder (PTSD)-related symptoms in refugees.Method: We searched Medline, EMBASE, PsycINFO, CINAHL, and Global Index Medicus from inception to 19 December 2023. We included controlled studies using any cognitive behavioural therapy (CBT) or CBT-based therapies delivered over a short time (< 3 months), which reported mental health outcomes pre-and post-intervention. We conducted meta-analyses using random effects to derive pooled summary statistics. The quality of the evidence was assessed with the Cochrane Risk of Bias (RoB2) and ROBINS-I tools. This study is registered on the Open Science Framework, DOI 10.17605/OSF.IO/9CXU4.Results: 34 eligible studies across 37 publications were retrieved for analysis, and 33 studies with 4479 participants were included in the meta-analysis. There was an overall improvement in immediate mental health outcomes for all three domains, with analysis of 13 studies on anxiety outcomes (SMD -1.12, 95% CI -1.72 to -0.52), 20 studies on depression (SMD -1.04, 95% CI -1.97 to -0.11), and 24 studies on PTSD (SMD -0.82, 95% CI -1.20 to -0.45). At 3 to 6-month follow-up, however, analysis of mental health outcomes shows no significant change from baseline, with a SMD of 0.24 (95% CI -0.94 to 1.42) across 4 studies, -0.73 (95% CI -2.14 to 0.68) across 9 studies, and 0.29 (95% CI -0.94 to 1.53) across 12 studies for anxiety, depression, and PTSD respectively.Conclusion: Low-quality evidence shows brief psychological interventions have a positive immediate effect on refugees and internally displaced people's mental well-being. However, these effects do not persist in the short-term follow up. Heterogeneity was high, even among subgroups, impacting our findings' generalisability.

Psychological Interventions for PTSD, Depression, and Anxiety in Child, Adolescent and Adult Forced Migrants: A Systematic Review and Frequentist and Bayesian Meta-Analyses

OBJECTIVE

The number of forced migrants has been rising for years. Many forced migrants suffer from post-traumatic stress disorder (PTSD), depression, and/or anxiety and need treatment. Here, we evaluate the effectiveness of psychological interventions (CBT, EMDR, expressive/art, mindfulness, mixed elements, NET and psychoeducation) in reducing symptoms of PTSD, depression, and anxiety in forced migrants.

DESIGN AND DATA SOURCES

Systematic searches in PubMed and Web of Science and searches of preprint servers and grey literature were performed (final search date: 1 September 2023). Random-effects frequentist and Bayesian meta-analyses were used for data synthesis.

RESULTS

We included 84 studies on treatment effects in adults (pooled N = 6302) and 32 on children and adolescents (pooled N = 1097). Our data show a reduction in symptoms of PTSD, depression and anxiety symptoms in both adults and child/adolescent forced migrants. Pooled pre- to post-treatment effects (effect size Cohen's d) ranged from -1.03 to -0.26 for PTSD, from -0.91 to -0.11 for depression and from -0.91 to -0.60 for anxiety, without there being differences in outcome per study design (i.e., RCT comparison vs. non-RCT comparison vs. single arm treatment study). Treatment effects remained evident over follow-up, and not a single type of treatment stood out as being superior to other treatment types. Structural differences in populations (e.g., regarding country of origin) over studies, however, could have hampered the validity of the comparisons between study characteristics such as treatment type.

CONCLUSION

Our findings support the effectiveness of psychological treatment in adult and child/adolescent forced migrants.

Depression and loneliness among Sub-Saharan immigrants living in the greater Paris area: results from the MAKASI empowerment stepped wedge cluster randomised controlled trial

PURPOSE

The MAKASI intervention aimed to empower Sub-Saharan African immigrants living in precarious situations in the Paris metropolitan area. Because there are factors specifically related to immigration that may increase the risk for common mental disorders, the present study aimed to examine participants' levels of depression and loneliness and analyze the effect of the intervention on depression and loneliness.

METHODS

The MAKASI study was designed as a stepped wedge cluster randomized trial. Study participants were recruited through an outreach program led by a nongovernmental organization and randomly assigned to two clusters, with an intervention delay of 3 months between them. Participants were assessed for 6 months after inclusion and the effect of the intervention on depression and loneliness was assessed using generalized linear mixed models. The study was conducted from 2018 to 2021 and took in consideration whether being interviewed during one of the Covid-19 confinement had an effect on the results.

RESULTS

Between 2018 and 2021 a total of 821 subjects participated in the Makasi study. High levels of depression and loneliness were found in the study population. We found no effect of the intervention on depression [95% CI 0.77 to 2.40]. Similarly, no effect of the intervention was found on loneliness [95% CI 0.87 to 2.54].

CONCLUSIONS

The intervention tested did not appear to improve the level of depression and loneliness among participants. However, the high prevalence of mental and emotional problems in the study population suggests a public health crisis among immigrants in the greater Paris area.

Afghan mental health and psychosocial well-being: thematic review of four decades of research and interventions

BACKGROUND

Four decades of war, political upheaval, economic deprivation and forced displacement have profoundly affected both in-country and refugee Afghan populations.

AIMS

We reviewed literature on mental health and psychosocial well-being, to assess the current evidence and describe mental healthcare systems, including government programmes and community-based interventions.

METHOD

In 2022, we conducted a systematic search in Google Scholar, PTSDpubs, PubMed and PsycINFO, and a hand search of grey literature (N = 214 papers). We identified the main factors driving the epidemiology of mental health problems, culturally salient understandings of psychological distress, coping strategies and help-seeking behaviours, and interventions for mental health and psychosocial support.

RESULTS

Mental health problems and psychological distress show higher risks for women, ethnic minorities, people with disabilities and youth. Issues of suicidality and drug use are emerging problems that are understudied. Afghans use specific vocabulary to convey psychological distress, drawing on culturally relevant concepts of body-mind relationships. Coping strategies are largely embedded in one's faith and family. Over the past two decades, concerted efforts were made to integrate mental health into the nation's healthcare system, train cadres of psychosocial counsellors, and develop community-based psychosocial initiatives with the help of non-governmental organisations. A small but growing body of research is emerging around psychological interventions adapted to Afghan contexts and culture.

CONCLUSIONS

We make four recommendations to promote health equity and sustainable systems of care. Interventions must build cultural relevance, invest in community-based psychosocial support and evidence-based psychological interventions, maintain core mental health services at logical points of access and foster integrated systems of care.

Exploring trajectories of depressive symptoms in North Korean defectors: A latent class mixed analysis

BACKGROUND

North Korean defectors (NKDs) are known to be vulnerable to depression due to the influence of various psychosocial factors during their settlement process. Therefore, this study aimed to explore different trajectories of depressive symptoms in NKDs and identify predictors of the worsening of depressive symptoms. In particular, the focus was on whether posttraumatic stress disorder (PTSD) functions as a significant predictor.

METHODS

Participants consisted of 300 NKDs who settled in South Korea within 3 years of entering in the country. Five waves of longitudinal data collected from 2016 to 2019 were used. In this study, the North Korean Composite International Diagnostic Interview (NK-CIDI), a diagnostic interview tool, was conducted at baseline and depressive symptoms were measured at each wave. Trajectory identification was based on latent class mixed modeling. Logistic regression was used to extract the significant factors predicting a high/increasing depressive symptom trajectory.

RESULTS

Two trajectories of depressive symptoms were identified: "low/stable symptom" (76.7% of participants) and "high/increasing symptom" (23.3% of participants). Predictors of the high/increasing symptom group were being female and a low use of mental health services. Generalized anxiety disorder, social phobia, and alcohol dependence acted as significant predictors. Although PTSD was not a significant predictor, self-reported PTSD symptom scores were high in the high/increasing symptom group.

CONCLUSIONS

Identifying the trajectories of depressive symptoms in NKDs helps identify the risk factors of clinically vulnerable groups. In the process of establishing government-level interventions, it may be helpful to create a therapeutic environment. In addition, when evaluating initial psychiatric problems, it is important to primarily consider NKDs' anxiety levels and alcohol problems. There should also be an appropriate consideration of PTSD symptoms.
