The purpose of the Suicide Prevention Assistance Act is to enhance mental health support by establishing a grant program aimed at providing self-harm and suicide prevention services in primary care settings. The goal is to improve early detection and intervention for individuals at risk of self-harm or suicide. Key provisions of the Act include the establishment of a grant program managed by the Secretary of Health and Human Services. Primary care offices can apply for these grants to hire clinical social workers who will conduct screenings for self-harm and suicide among patients.
