Building on past efforts and on the experience of programs serving comparable populations, the program seeks to provide comprehensive services, including case management, residential and intensive outpatient treatment, perinatal care, and foster care services. The provision of services to program clients is implemented in a "women- sensitive" manner. The program is forging collaborative and coordinated service linkages to meet the many needs of California's ethnically and culturally diverse population of women and children. Part of the program is an evaluation component to measure changes in interagency collaboration and coordination in providing services to chemically dependent pregnant and parenting women and their children, to compare service delivery systems among pilot project sites and describe changes in service levels, and to determine program performance with the population served. A review of the literature on perinatal chemical dependency and a reivew of previous program efforts in the perinatal substance abuse field are presented. The impact of perinatal substance abuse and comprehensive approaches to such abuse are examined. 93 references
