We will iteratively adapt and modify the NC woman-focused intervention (Women's CoOp), including the field manual and instrumentation, to focus on pregnant African-American women who abuse crack, are currently in substance abuse treatment, and are at risk for HIV or are HIV positive. We then will test the newly developed intervention in a Stage IB pilot-sized randomized clinical trial (RCT) in a traditional substance abuse treatment clinic to determine (a) feasibility; (b) relative efficacy compared with substance abuse treatment-as-usual (TAU), across several domains of functioning (e.g., substance use, HIV risk behaviors); and (c) the intervention's potential mechanisms of action.
