Reducing drug use among methadone maintenance clients: Contingent reinforcement for morphine-free urines

Research output: Contribution to journalArticle

Abstract

This study assessed the impact on supplemental heroin use by seven methadone maintenance patients of providing extrinsic reinforcement contingent upon morphine-free urinalysis results. Reinforcement was available for morphine-free urine samples during randomly selected weeks. Reinforcement consisted of a choice between $15, two methadone take- home privileges, and two opportunities to self-regulate methadone dosage. The monetary reinforcer was chosen on 95% of reinforcement occasions. During contingent reinforcement the rate of morphine-positive urinalyses declined significantly below pre-study levels (Wilcoxon Test, P
