A combined cognitive and behavioral intervention for cocaine-using methadone clients

Abstract

Treating cocaine use by opiate-dependent clients in methadone programs is a well-documented challenge. Both behavioral (contingency management) and cognitive (relapse prevention) interventions have shown promise in helping engage these clients in treatment. In this study, the effectiveness of combining contingency management with a cocaine-specific relapse prevention counseling module was examined. Sixty-one cocaine-using methadone clients were randomly assigned to one of four treatment conditions to participate in the eight-week intervention and eight-week follow-up period. Using analysis of variance (ANOVA), differences in cocaine use and treatment retention were examined. Contingency management was significantly related to reductions in cocaine use and the counseling module was positively related to six-month retention rates. Both interventions were associated with positive treatment response but the effects were reflected in different behavioral outcomes.
