Psychosocial Preparedness for Disasters: A Scoping Review of International Models and Public Health Priorities

To map international models of psychosocial preparedness for disasters and identify recurrent public mental health priorities for policy, service readiness, and implementation.

Following PRISMA extension for scoping reviews (PRISMA-ScR) and Joanna Briggs Institute guidance, we searched PubMed (2015-2025) using two complementary strategies and mapped 35 included studies. Eight model families emerged, including community resilience and governance; non-specialist support and psychological first aid (PFA); integrated mental health and psychosocial support (MHPSS) across the disaster cycle; implementation and scale-up models; organizational and health-system preparedness; digital continuity models; monitoring and evaluation frameworks; and behavioral emergency response models. Across model families, preparedness was concentrated mainly on community and non-specialist levels, and emphasized trust, community capacity, task-sharing, workforce readiness, and continuity of care. The mapped literature supports psychosocial preparedness as a layered public health function rather than a post-event specialist intervention. Core priorities include pre-event governance, community engagement, supervised non-specialist delivery with referral pathways, workforce protection, digital continuity with clinical safeguards, and minimum monitoring standards. Future work should prioritize implementation-focused research and outcome evaluation across diverse disaster settings.
