This article describes a research demonstration project currently underway in Los Angeles county. The study is a randomized evaluation of treatment strategies for homeless persons with serious mental and substance use disorders. This paper describes the study population, the treatment philosophy underlying the programs being studied, the design of the two treatment programs, and implementation experiences occurring during the first year of project operations. The existing residential program staff was able to adapt to treating a different client population. Considerable challenges were encountered in implementing the new nonresidential program. Implementation of the randomized design and longitudinal follow-up has been successful.
