The purpose of this project at RTI International is to support an evaluation of three discretionary grant programs for the Substance Abuse and Mental Health Services Administration (SAMHSA) – the State Adolescent Treatment Enhancement and Dissemination grants (SAT-ED), the State Adolescent and Transitional Aged Youth Treatment Enhancement and Dissemination grants (SYT), and the Services Grant Program for Residential Treatment for Pregnant and Postpartum Women (PPW) programs. Key objectives are to: (1) perform separate cross-site evaluations for SAT-ED and SYT, which are newer Center for Substance Abuse programs and have never been evaluated, (2) provide a report on pregnant/post-partum women in each of the 3 programs; (3) provide ad hoc reports for the three programs; and (4) provide analysis for examining the feasibility, utility, and sustainability of future adolescent and PPW cohorts.
