Employment-based Reinforcement to Motivate Drug Abstinence in the Treatment of Drug Addiction. - 2
A Therapeutic Workplace for Drug Abusers
The purpose of this study is to determine whether long-term exposure to the Therapeutic Workplace intervention could sustain drug abstinence over an extended period of time in heroin- and cocaine-dependent, unemployed, treatment-resistant young mothers.
The current study is a continuation of the research into the development and evaluation of a novel treatment designed to address the chronic, persistent nature of drug addiction. This treatment, called the Therapeutic Workplace, integrates abstinence reinforcement contingencies of proven efficacy into a model supported work program. Participants were paid to work or to train in the Therapeutic Workplace but had to provide drug-free urine samples to gain daily access. Forty participants were randomly assigned to a Therapeutic Workplace or usual care control group. Therapeutic Workplace participants could work for about 5 years. This study reports the effects of the intervention over a follow-up period of 8 years after treatment initiation.
