This report summarizes the relevant research that connects homelessness, alcohol and other drug abuse, and employment and job training services. It draws on the National Institute on Alcohol Abuse and Alcoholism and the Department of Labor demonstration projects as well as other programs to provide examples of various innovative programs across the country that have made progress in meeting the considerable challenge of serving the comprehensive employment needs of homeless persons who have alcohol and other drug problems. Chapter 1 discusses employment experiences of homeless persons with alcohol and other drug problems, including the scope of the problem, epidemiological perspectives, and ethnographic perspectives. Chapter 2 examines the connection between treatment and work, including recovery and vocational services, developments in combining treatment and vocational services, and work issues across the recovery continuum. Chapter 3 provides brief descriptions of 15 innovative programs in 5 U.S. cities that offer vocational training and other employment services especially suitable to the needs of individuals with alcohol and other drug problems. Chapter 4 discusses future directions for program development. Appendix A presents a glossary of key terms. Appendix B describes the protocol for site visit to programs. A five-page list of references is included. (ABL)
