The Mental Health and Anti-Addiction Services Administration (MHAASA) of Puerto Rico proposes a 55-year PR Youth Suicide Prevention Project (PR-YSP) to expand capacity of youth-serving systems (education, juvenile justice, and child welfare) to identify, appropriately intervene and refer a total of 675 at risk youth, 10-24 years, and offer Evidence Based (ASIST, CBT for adolescent suicidality and ROS) early mental health interventions in its San Juan clinic.
