Rationale: The ongoing COVID-19 pandemic has a major and potentially long-lasting effect on mental health and wellbeing across populations worldwide. Vulnerable groups, such as asylum seekers, refugees and migrants, are disproportionally affected by the COVID-19 pandemic. There is a high need for psychosocial interventions that can target the most prevalent mental health problems as a result of the COVID-19 pandemic, addressing the needs of many people in a way that maximizes the use of resources. The World Health Organization (WHO) has developed two scalable, low-intensity psychological interventions: Doing What Matters in times of stress (DWM; a self-help intervention) and Problem Management Plus (PM+; a face-to-face intervention). DWM and PM+ can be delivered by paraprofessionals, are applicable to a variety of mental health problems (depression, anxiety and PTSD), and can be adapted to different populations, cultures and languages. Both DWM and PM+ have been proven to be effective on their own. In this study, DWM and PM+ will be combined into a stepped-care intervention. This study is part of the larger EU H2020-RESPOND project, which aims to improve the preparedness of the European mental health care system in the face of future pandemics.~Objective: The main objective is to evaluate the implementation and (cost-)effectiveness of the culturally and contextually adapted DWM/PM+ stepped-care programs amongst asylum seekers, refugees, and/or migrants living in Italy during the COVID-19 pandemic in terms of mental health outcomes, resilience, wellbeing, health inequalities, and costs to health systems. The main hypothesis is that the stepped-care DWM/PM+ intervention together with psychological first aid (PFA) in addition to care-as-usual (CAU) will be more effective in decreasing psychological distress and symptoms of mental health problems than PFA and CAU alone. We aim to conduct a randomized controlled trial (RCT) to assess the (cost-)effectiveness of the stepped-care DWM/PM+ intervention, and to identify (a) barriers and facilitators to treatment engagement and adherence and (b) opportunities for scaling up the implementation of the DWM/PM+ intervention within the existing health care system in Italy.~Study design: pragmatic implementation trial with a single-blinded, randomized, parallel-group design. The final phase of the trial will consist of a qualitative process evaluation with individual interviews and focus group discussions (FGDs).~The qualitative phase will include some participants in the randomized trial who completed DWM (n=2/4;), who completed PM+ (n=2/4), who dropped-out during DWM (n=2/4), and who dropped-out during PM+ (n=2/4); (b) local stakeholders (n=10/15) (c) facilitators of the DWM and PM+ intervention (both helpers and trainers/supervisors).~Study population: Adult asylum seekers, refugees or migrants with self-reported elevated psychological distress (K10 >15.9) (n=212).~Intervention: All participants (in both the treatment and the comparison group) will receive Psychological First Aid (PFA) and CAU. In addition to PFA and CAU, the treatment group will receive the stepped-care intervention (DWM with or without PM+). The stepped-care intervention consists of DWM (step 1), and conditionally PM+ (step 2) if participants still meet criteria for psychological distress (K10 >15.9) 2 weeks after having received DWM.~DWM, i.e. a self-help book with pre-recorded audios, has been adapted as an online intervention (phase 1). PM+ consists of five sessions and will be delivered by trained peer-support helpers in person or via teleconferencing in individual or group format. In addition to PFA, the comparison group will receive CAU which ranges from community care to specialized psychological treatments, according to the needs and clinical characteristics of participants.~Main study parameters/endpoints: Screening for inclusion and exclusion criteria will be interviewer-administered, inperson or through (video) calls. For all participants, online assessments will take place at baseline, at 2 weeks after having received DWM, at 1 week and at 2 months after having received PM+. The primary outcome will be the decrease in symptoms of anxiety and depression from baseline to two-month follow-up, measured through the sum score of the Patient Health Questionnaire (PHQ-9) and General Anxiety Disorder-7 (GAD-7), i.e. the PHQ-Anxiety and Depression Score (PHQ-ADS). We expect to detect a Cohen's d effect size of 0.3 in the DWM/PM+ group at 2 months post-treatment. Additional health outcomes include level of anxiety (GAD-7) and depression (PHQ-9), symptoms of posttraumatic stress disorder (PCL-5), resilience (Mainz Inventory of Microstressors, MIMIS), quality of life (5-level EQ-5D version, EQ-5D-5L), and cost of care (Client Service Receipt Inventory, CSRI). Additional study parameters will include demographic data, COVID-19 related (exposure) variables, treatment fidelity, satisfaction and acceptability of the intervention program, and implementation indicators (such as reach, dose, resource use, intervention-related costs). Through FGDs and interviews at the end of the trial, the feasibility of scaling-up the implementation on the stepped-care DWM/PM+ intervention within asylum seekers, refugees, and migrants in Italy.
This randomized controlled trial will evaluate the implementation and (cost-)effectiveness of the culturally and contextually adapted Doing What Matters in times of stress (DWM) and Problem Management Plus (PM+) stepped-care programs amongst asylum seekers, refugees, and/or migrants living in Italy. Outcomes include mental health, resilience, wellbeing, health inequalities, and costs to health systems.
