Study Arms (3)

Usual Care Control

NO INTERVENTION

Participants in this group were offered employment in the Therapeutic Workplace without urinalysis testing or the methadone treatment requirement. They were offered the methadone treatment but were not required to join in order to gain access to the workplace.

Methadone Contingency Group

EXPERIMENTAL

Participants in this group were allowed to work and earn wages as long as they enrolled in the methadone treatment and continued to take does of methadone consistently (employment-based reinforcement).

Behavioral: methadone contingency

Methadone & Abstinence Contingency

EXPERIMENTAL

Participants in this group were able to access work if they enrolled in the methadone treatment and consistently took their medication, but they also received a decrease in base pay if they test positive for opiates or cocaine on the drug screens (employment-based reinforcement).

Behavioral: methadone contingencyBehavioral: Methadone & Abstinence Contingency

Interventions

Participants had to enroll in methadone treatment and take daily doses of methadone to gain access to the workplace.

Methadone & Abstinence ContingencyMethadone Contingency Group

Participants had to enroll in methadone treatment and take daily doses of methadone to gain access to the workplace and they had to provide opiate and cocaine negative urine samples to maintain the maximum pay.

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Individuals were eligible if they were: * at least 18 years old, * reported injection drug use in the past 30 days, * met the Diagnostic and Statistical Manual (DSM)-IV criteria for opioid dependence, * reported using heroin at least 21 out of the past 30 days, * provided an opiate-positive urine sample, * showed visible signs of injection drug use (i.e., track marks), * reported not receiving substance abuse treatment in the past 30 days, * lived in Baltimore, * and were unemployed. Participants were excluded if they * had current severe psychiatric disorders or chronic medical conditions that would interfere with their ability to participate in the workplace, * reported current suicidal or homicidal ideation, * had physical limitations that would prevent them from using a keyboard, * had medical insurance coverage (as this would disqualify them from receiving interim methadone treatment), * were pregnant or breastfeeding, * or were currently considered a prisoner. Eligible participants were invited to participate in a 4-week induction. Participants who attended the workplace for at least five minutes on two out of five workdays in the last week of induction were randomly assigned to one of three conditions and were invited to attend the workplace for an additional 26 weeks
