Exposure to adversity, particularly in early childhood, can lead to lifelong struggles with learning and adverse physical and mental health. Mental health promotion and prevention, care services and psychosocial approaches can play an important role in mitigating these adversities and improving a range of developmental outcomes for children – including learning, relational and social skills, and health and nutrition. This study explores effective mental health and psychosocial support (MHPSS) programming integrated within education in emergencies (EiE).
