Cocaine and other substance abuse has been found to be a contributing or primary cause of homelessness in urban men. This project evaluated the effectiveness of the Grant Street Partnership (GSP), a shelter-based treatment program for homeless, cocaine-abusing men, consisting of 90 days of residential treatment and 6 months of aftercare. We tested the hypothesis that the 182 men randomized to the GSP group, as compared to the 112 men randomized to a “usual services” group, would show significantly greater improvement over time in the areas of drug use and residential and economic stability. An 80% response rate was achieved overall for the five follow-up points. Cocaine use, defined as use of cocaine once in the prior 30 days, declined from about 90% at baseline for both groups to 11% in the GSP group and 55% in the control group at 21 months. The GSP group was also more likely than the usual services group to have achieved residential stability by the time of the 9 month follow-up. Neither group experienced an improvement over time in employment status.
