REPSSI is a non-profit organisation working to lesson the social and psychosocial (emotional) impact of poverty, conflict, HIV and AIDS among children and youth across 13 Eastern and Southern African countries. The event is a mental health and substance use disorders training to identify other mental disorders and infectious diseases that frequently occur alongside substance use disorders. The MHPSS that attend this training will learn how to screen for mental health and substance use disorders and interpret the results of screening tools in order to improve HIV treatment outcomes through detection and intervention of co-occurring alcohol and other drug use among children and youth.
