Mental Health Interventions for Displaced Populations

Displaced populations face heightened exposure to traumatic events, disrupted social networks and precarious living conditions that collectively increase the risk of mental health disorders. Interventions have evolved from singular, diagnosis-driven therapies towards integrated programmes that combine psychological, social and community components. Task-shifting strategies have become central to delivering care in contexts with few mental health specialists, enabling trained lay counsellors to provide evidence-based psychosocial support. Group-based interventions, peer support networks and culturally adapted cognitive behavioural therapies have demonstrated feasibility and acceptability across diverse settings. Emerging transdiagnostic models allow a single treatment protocol to address multiple co-occurring disorders, reducing the need for separate treatments for depression, anxiety or post-traumatic stress disorder. Digital platforms and mobile applications are increasingly being harnessed to overcome geographic and logistical barriers, while stepped-care approaches ensure that individuals receive the intensity of intervention appropriate to their level of need. Collaboration between humanitarian agencies, local health systems and affected communities underpins scalable and sustainable delivery, emphasising capacity building, monitoring and evaluation, and the integration of mental health into primary care and multisectoral programmes.
