Review published: 2006.

Quality assessment

This review concluded that contingency management methods promote abstinence from alcohol, tobacco and illicit drugs during the treatment of substance use disorders. Evaluation of the reliability of the authors' conclusions is not possible given their informal assessment of the validity of the included studies, high attrition rates, and the unknown influence of studies contributing more than one comparison to the review. Full critical summary


AIMS: To examine the effectiveness of contingency management (CM) techniques in treating substance use disorders (i.e. illicit drugs, alcohol, tobacco).

DESIGN: Meta-analysis was used to determine the average effect size and potential moderators in 47 comparisons of the effectiveness of CM from studies based on a treatment-control group design and published between 1970 and 2002.

FINDINGS: The mean effect size (ES) of CM was positive, with a magnitude of d = 0.42 using a fixed effects model. The magnitude of the ES declined over time, following treatment. CM was more effective in treating opiate use (d = 0.65) and cocaine use (d = 0.66), compared with tobacco (d = 0.31) or multiple drugs (d = 0.42). Larger effect sizes were associated with higher researcher involvement, earlier studies and shorter treatment duration.

CONCLUSIONS: Study findings suggest that CM is among the more effective approaches to promoting abstinence during the treatment of substance use disorders. CM improves the ability of clients to remain abstinent, thereby allowing them to take fuller advantage of other clinical treatment components.
