Abstract
Crack cocaine dependence rapidly leads to physical deterioration and severe social consequences. There is no widely accepted standard of treatment. As such, it is important to attract broad samples of patients into treatment research to improve efficacy and to establish generalizability. Better understanding of what attracts different subgroups of cocaine users into treatment, particularly research-based treatment, is needed. This article assesses the efficacy of six different recruitment strategies for attracting different populations of male veterans into treatment for crack cocaine dependence. New directions are outlined for the examination of recruitment strategies.
