What was done

The authors conducted an overview of research evaluating the voucher-based incentive approach (contingency management) in substance abuse treatment, focusing on its initial use in cocaine dependence and subsequent extension to other substances and populations.

What was found

The abstract reports no numerical outcomes, statistics, or effect sizes. It qualitatively concludes that voucher efficacy is well established for improving retention and abstinence in cocaine-dependent outpatients, with emerging applications in alcohol, marijuana, nicotine, and opioid dependence, as well as in special populations (adolescents, pregnant/postpartum women, and patients with serious mental illness).

Why it matters

Voucher incentives provide an empirically supported behavioral approach to reinforce treatment retention and substance abstinence across multiple substance use disorders.

Limits

The abstract contains no quantitative data, search methodology, or study counts. As a narrative review, it lacks formal risk of bias assessment and does not report on the long-term durability of abstinence after vouchers are discontinued.
