Summary
This study found that contingency management effectively reduced cocaine use in methadone-maintained clients. A cocaine-specific relapse prevention module improved long-term treatment retention, highlighting distinct benefits of each intervention.
Area of Science:
- Addiction Medicine
- Clinical Psychology
- Psychopharmacology
Background:
- Cocaine use among opiate-dependent individuals in methadone programs presents a significant treatment challenge.
- Behavioral (contingency management) and cognitive (relapse prevention) interventions show promise for client engagement.
Purpose of the Study:
- To examine the effectiveness of combining contingency management with a cocaine-specific relapse prevention counseling module.
- To assess the impact on cocaine use and treatment retention in methadone clients.
Main Methods:
- Sixty-one cocaine-using methadone clients were randomly assigned to four treatment conditions.
- An eight-week intervention followed by an eight-week follow-up period was implemented.
- Analysis of variance (ANOVA) was used to analyze differences in cocaine use and retention.
Main Results:
- Contingency management significantly reduced cocaine use.
- The relapse prevention counseling module positively correlated with six-month retention rates.
- Both interventions demonstrated positive treatment responses, but with different behavioral outcomes.
Conclusions:
- Combining contingency management and relapse prevention counseling offers a dual benefit for cocaine-using methadone clients.
- Contingency management directly impacts cocaine use reduction.
- Relapse prevention counseling enhances long-term treatment engagement and retention.
