This document describes the essential interventions in mental health and psychosocial support (MHPSS) that should be developed on an intersectoral basis in countries and communities. Its frame of reference is the Inter-Agency Standing Committee (IASC) intervention pyramid for MHPSS services. The pyramid shows different levels of support, ranging from social considerations, safety, and basic needs, to the provision of specialized services for the management of more severe conditions, as well as the probable volume of demand at each established level.
