Mental Health Crises in Post-Conflict Regions: Interdisciplinary Approaches to Trauma Healing

Abstract

Post-conflict regions face a dual burden of rebuilding social infrastructures while addressing widespread mental health crises driven by trauma, displacement, and chronic stressors. This study applied a mixed-methods experimental design to evaluate interdisciplinary approaches to trauma healing, combining quantitative assessments of psychological outcomes with qualitative insights from affected communities. Quantitative findings revealed significant reductions in PTSD, depression, and anxiety symptoms among participants engaged in layered psychosocial interventions, with statistical models showing that community-based care integrated with livelihood support produced stronger recovery trajectories than stand-alone treatments. Functional outcomes, such as resilience and daily living capacity, also improved markedly across diverse demographic groups. Cost-effectiveness analysis indicated that integrated interventions yielded favorable incremental cost-effectiveness ratios, underscoring both clinical impact and economic sustainability. Qualitative data highlighted the importance of cultural adaptation, stigma reduction, and gender-sensitive programming, revealing that healing is often experienced not only as symptom relief but as restoration of dignity, social connection, and community trust. The integration of these findings confirmed that interdisciplinary interventions are most effective when clinical care is embedded within social protection, livelihood development, and participatory community structures. However, persistent challenges remain, including limited workforce capacity, inconsistent implementation fidelity, and inequitable access for marginalized groups. Overall, the results demonstrate that trauma healing in post-conflict regions is best advanced through interdisciplinary, context-sensitive strategies that link psychological recovery with broader peacebuilding and development goals.
