Background: In asylum seekers and refugees, the frequency of mental disorders, such as depression, anxiety and post-traumatic stress disorder, is higher than the general population, but there is a lack of data on risk factors for the development of mental disorders in this population., Aim: This study investigated the risk factors for mental disorder development in a large group of asylum seekers and refugees resettled in high- and middle-income settings., Methods: Participant-level data from two randomized prevention studies involving asylum seekers and refugees resettled in Western European countries and in Turkey were pooled. The two studies randomized participants with psychological distress, but without a diagnosis of mental disorder, to the Self-Help Plus psychological intervention or enhanced care as usual. At baseline, exposure to potentially traumatic events was measured using the Harvard Trauma Questionnaire-part I, while psychological distress and depressive symptoms were assessed with the General Health Questionnaire and the Patient Health Questionnaire. After 3 and 6 months of follow-up, the proportion of participants who developed a mental disorder was calculated using the Mini International Neuropsychiatric Interview., Results: A total of 1,101 participants were included in the analysis. At 3- and 6-month follow-up the observed frequency of mental disorders was 13.51% (115/851) and 24.30% (207/852), respectively, while the frequency estimates after missing data imputation were 13.95% and 23.78%, respectively. After controlling for confounders, logistic regression analysis showed that participants with a lower education level ( p  = .034), a shorter duration of journey ( p  = .057) and arriving from countries with war-related contexts ( p  = .017), were more at risk of developing mental disorders. Psychological distress ( p  = .004), depression ( p  = .001) and exposure to potentially traumatic events ( p  = .020) were predictors of mental disorder development., Conclusions: This study identified several risk factors for the development of mental disorders in asylum seekers and refugees, some of which may be the target of risk reduction policies. The identification of asylum seekers and refugees at increased risk of mental disorders should guide the implementation of focused preventative psychological interventions.

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., Competing Interests: No potential conflict of interest was reported by the author(s)., (© 2022 The Author(s).

Importance: The cost-effectiveness of the Self-Help Plus (SH+) program, a group-based, guided, self-help psychological intervention developed by the World Health Organization for people affected by adversity, is unclear., Objective: To investigate the cost-utility of providing the SH+ intervention combined with enhanced usual care vs enhanced usual care alone for Syrian refugees or asylum seekers hosted in Turkey., Design, Setting, and Participants: This economic evaluation was performed as a prespecified part of an assessor-blinded randomized clinical trial conducted between October 1, 2018, and November 30, 2019, with 6-month follow-up. A total of 627 adults with psychological distress but no diagnosed psychiatric disorder were randomly assigned to the intervention group or the enhanced usual care group., Interventions: The SH+ program was a 5-session (2 hours each), group-based, stress management course in which participants learned self-help skills for managing stress by listening to audio sessions. The SH+ sessions were facilitated by briefly trained, nonspecialist individuals, and an illustrated book was provided to group members. Th intervention group received the SH+ intervention plus enhanced usual care; the control group received only enhanced usual care from the local health care system. Enhanced usual care included access to free health care services provided by primary and secondary institutions plus details on nongovernmental organizations and freely available mental health services, social services, and community networks for people under temporary protection of Turkey and refugees., Main Outcomes and Measures: The primary outcome measure was incremental cost per quality-adjusted life-year (QALY) gained from the perspective of the Turkish health care system. An intention-to-treat analysis was used including all participants who were randomized and for whom baseline data on costs and QALYs were available. Data were analyzed September 30, 2020, to July 30, 2021., Results: Of 627 participants (mean [SD] age, 31.3 [9.0] years; 393 [62.9%] women), 313 were included in the analysis for the SH+ group and 314 in the analysis for the enhanced usual care group. An incremental cost-utility ratio estimate of T£6068 ($1147) per QALY gained was found when the SH+ intervention was provided to groups of 10 Syrian refugees. At a willingness to pay per QALY gained of T£14 831 ($2802), the SH+ intervention had a 97.5% chance of being cost-effective compared with enhanced usual care alone., Conclusions and Relevance: This economic evaluation suggests that implementation of the SH+ intervention compared with enhanced usual care alone for adult Syrian refugees or asylum seekers hosted in Turkey is cost-effective from the perspective of the Turkish health care system when both international and country-specific willingness-to-pay thresholds were applied.

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., Trials Registration Numbers: NCT03571347, NCT03587896., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.
