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

Abstract

IntroductionThis 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 analysisTwo 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 disseminationThe 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 numbersNCT03571347,NCT03587896.

Reducing psychological distress and depression in humanitarian emergencies: An essential role for nonspecialists

“…Jordans and colleagues’ study contributes compelling evidence on the effectiveness of a nonspecialist-delivered psychological intervention in a humanitarian setting, adding to prior research on the PM+ program in Pakistan [ 16 ] and Kenya [ 17 ], as well as studies of similar brief psychological interventions in refugees and asylum seekers in Uganda [ 18 ], Western Europe, and Turkey [ 19 , 20 ]. With nonspecialist-delivered psychological interventions showing promising outcomes across diverse settings, contexts, and cultures, our attention must now focus on sustaining quality delivery of these programs while scaling up access to reach the millions of people facing psychological distress and mental health consequences due to humanitarian emergencies globally.…”

A network meta-analysis of psychosocial interventions for refugees and asylum seekers with PTSD

“…84 Based on these considerations, a new generation of studies have recently been designed to demonstrate the effectiveness of culturally adapted psychosocial interventions delivered by non-specialist trained facilitators, or lay counsellors, sharing the same cultural background of the target refugee population. [85][86][87][88][89] An added value of employing trained non-specialist facilitators includes lower healthcare costs, which may be particularly relevant in low-resource settings. 90 91 Finally, future studies should additionally investigate the efficacy, feasibility and sustainability of psychosocial interventions delivered through the use of synchronous and asynchronous online communication devices.…”

Promotion, prevention and treatment interventions for mental health in low- and middle-income countries through a task-shifting approach

“…These interventions to prevent mental disorders may be delivered at individual or group level, in a variety of settings (antenatal and postnatal visits, home visits, community settings, schools, etc.). These interventions include psychosocial support for persons with subclinical levels of mental disorders (Purgato et al ., 2019 a ), such as mentoring programmes aimed at children with behavioural problems; psychological first aid for people with heightened levels of psychological distress after exposure to severe stressors, loss or bereavement (Tol et al ., 2015). This includes facilitator-guided self-help group interventions, as for example the WHO Self-Help Plus (Epping-Jordan et al ., 2016; Purgato et al ., 2019 a ).…”
