Integration of psychological interventions in multi-sectoral humanitarian programmes: a systematic review.

Background: Every year, millions of people are affected by humanitarian crises. With a growing population of people affected, the need for coordination and integration of services aiming to improve the effectiveness of mental health and psychosocial support also grows. In this study, we examine how psychological interventions in humanitarian settings globally have been implemented through integration into programming outside of formal healthcare delivery through multisectoral integration.
