PROTOTYPES, Centers for Innovation in Health, Mental Health and Social Services, propose a specialized, intensive residential treatment program for pregnant and postpartum women (PPW). This project will allow PROTOTYPES to expand the availability of comprehensive, integrated, high quality residential substance abuse treatment services for low-income women, age 18 and over, who are pregnant and postpartum, and for their minor children, ages 0-17 years, and family members, who have limited access to quality health services. The project will be implemented in Los Angeles County, California. PROTOTYPES propose to use this new funding to serve 40 new PPW women and their children and family members per year. The expansion and value added with the PPW funding is that the program will be able to expand services to all the children of the women and to the women's extended families. Treatment will take place in the newly constructed, state-of-the-art, 11,000 sq. ft. building on the Women's Center campus, with an entire residential wing to be devoted to this new Intensive Residential program. This will allow the women to bond with one another easily as they enter treatment and later to gradually increase their integration into the larger therapeutic community on the campus. Goals of the project are to: (1) Decrease the use and abuse of prescription, alcohol, tobacco, illicit, and other harmful drugs; (2) Increase safe and healthy pregnancies, improve birth outcomes, and reduce related effects of maternal drug abuse on infants and children; (3) Improve the mental health and physical health of the women and children; (4) Improve family functioning, economic stability, and quality of life; and (5) Decrease involvement in and exposure to crime, violence, sexual and physical abuse, and child abuse and neglect. Project evaluation will be carried out by The Measurement Group (TMG). The project will use evidence-based practices and a specialized child skill-building intervention.
