Részletes leírás
Social service workers are chronically exposed to traumatic content and occupational stress, placing them at elevated risk for psychological distress and secondary traumatic stress. A universal-prevention approach is adopted: no individual stress threshold is required for inclusion, as the occupational context itself serves as a high-risk filter.
Randomization is performed at the institution (cluster) level rather than the individual level to prevent contamination, accommodate the group format of the intervention, and reflect logistical realities of the institutions. Two clusters are allocated to the intervention arm and two to the control arm (1:1), stratified by service type. The allocation list is generated by a researcher independent of the field team, and assignment is revealed only after baseline (T0) assessment is complete. The trial is single-blind: participants and facilitators cannot be blinded, but outcome assessment is self-report via online forms (structural assessor masking) and the data analyst is blinded to group allocation (groups coded A/B until analysis is complete).
The SH+ intervention is a low-intensity, guided self-help program based on Acceptance and Commitment Therapy, delivered by trained non-specialist facilitators in a group format across five weekly sessions of approximately two hours each. It uses a pre-recorded audio course complemented by the illustrated self-help book "Doing What Matters in Times of Stress"; participants receive the book and weekly audio exercises for between-session practice. The ECAU control comprises continued access to existing institutional support and routine services plus a comprehensive psychoeducational information pack (stress-coping strategies, recognition of stress symptoms, and pathways to mental health and psychosocial support services in Istanbul). After the 3-month follow-up (T2), control-arm participants are offered the opportunity to attend SH+ sessions.
Assessments are collected at baseline (T0, pre-randomization), post-intervention (T1), and 3-month follow-up (T2) via self-report online forms. Feasibility progression thresholds are pre-specified: recruitment rate ≥70%, session attendance ≥70% (attending at least 3 of 5 sessions), and follow-up completion ≥75%. Preliminary effectiveness is analyzed using design-effect-adjusted methods or linear mixed models accounting for clustering; effect sizes (Cohen's d) with 95% confidence intervals are reported. The intraclass correlation coefficient (ICC) for the primary clinical outcome (PSS-10) is estimated to inform sample-size planning for a future full-scale cluster RCT.
