By providing in-depth descriptions of the 23 promising programs available from the Program Archive on Sexuality, Health and Adolescence (PASHA), the "PASHA Program Sourcebook" offers practitioners a detailed look at "what works" to prevent pregnancy and sexually transmitted diseases/human immunodeficiency virus and acquired immune deficiency syndrome (STD/HIV/AIDS) among teens. The introductory chapter outlines the problem of teen pregnancy in the United States and discusses different approaches to address it. The remainder of the book describes each program in detail--presenting the program's theoretical framework, target population, the schedule and overview of activities comprising the intervention, and implementation guidelines. A description of the original program evaluation is also presented. By describing the programs in such depth, it is hoped the book will serve as a practical resources for those interested in learning about and developing promising prevention programs. (SLD)
