Efficacy of a World Health Organization-Guided Self-Help Intervention for Reducing Psychological Distress in Afghan Refugees: Randomized Controlled Trial
AI Summary
Facilitator-guided DWM significantly reduced psychological distress versus control at posttreatment and 1-month follow-up (Cohen d 0.56 and 0.45).
DWM produced greater improvements in PTSD symptoms, well-being, social functioning, functional impairment, and personally identified problems.
Individually supported self-help DWM is feasible, scalable, and effective for improving mental health among urban refugees in transit settings.

ABSTRACT
BACKGROUND: Common mental health disorders are highly prevalent among refugees. There is an urgent need to address the mental health burden in this population.
OBJECTIVE: This study tested the efficacy of an individually supported self-help stress-management intervention developed by the World Health Organization-Doing What Matters in Times of Stress (DWM)-in reducing psychological distress and improving functioning among refugees in Indonesia, a major transit country in the Asia-Pacific region.
METHODS: A single-blind randomized controlled trial with 303 Farsi-speaking refugees was conducted between June 2024 and June 2025. Participants with moderate to high psychological distress (Kessler Psychological Distress Scale [K10] score≥20) were randomly allocated to the facilitator-guided individual DWM condition (n=202) or a repeated assessment control condition (n=101). The primary outcome was psychological distress (K10 score) at the posttreatment assessment. Secondary outcomes were posttraumatic stress disorder symptoms, functional impairment, social functioning, and personally identified problems.
RESULTS: Intent-to-treat analysis indicated that participants in the DWM condition showed greater reductions in K10 scores than those in the repeated assessment control condition (posttreatment: β=-.563, SE=0.124; P<.001; Cohen d=0.56; 1-month follow-up: β=-.447, SE=0.140; P=.002; Cohen d=0.45). Similarly, those participants in the DWM condition reported greater improvements in posttraumatic stress disorder symptoms, well-being, social functioning, functional impairment, and personally identified psychological problems. No serious adverse events were reported.
CONCLUSIONS: The findings provide the first evidence for the effectiveness of DWM in reducing psychological distress and improving overall functioning among urban refugees living in a transit setting. Individually supported self-help interventions such as DWM mayoffer an effective, feasible, and scalable approach to improving mental health for refugees.
