Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Therapeutic Workplace

Contingency management. Invited to work in the Therapeutic Workplace. Completed monthly assessments.

Group Type EXPERIMENTAL

Contingency management

Intervention Type BEHAVIORAL

Invited to attend the Therapeutic Workplace 3 hr per day, Monday through Friday. Each day when a participant reported to the workplace, she was required to provide a urine sample. If the sample tested negative for opiates and cocaine, she was allowed to work that day. Participants who gained entrance to the workplace participated in basic skills education and job skills training throughout each 3-hr work shift.

Usual Care Control Group

No intervention. Not invited to work int the Therapeutic Workplace. Completed monthly assessments.

Group Type NO_INTERVENTION
