Objective: Determine if employment-based reinforcement can increase methadone treatment engagement and drug abstinence in out-of-treatment injection drug users., Method: This study was conducted from 2008 to 2012 in a therapeutic workplace in Baltimore, MD. After a 4-week induction, participants (N=98) could work and earn pay for 26 weeks and were randomly assigned to Work Reinforcement, Methadone & Work Reinforcement, and Abstinence, Methadone & Work Reinforcement conditions. Work Reinforcement participants had to work to earn pay. Methadone & Work Reinforcement and Abstinence, Methadone, & Work Reinforcement participants had to enroll in methadone treatment to work and maximize pay. Abstinence, Methadone, & Work Reinforcement participants had to provide opiate- and cocaine-negative urine samples to maximize pay., Results: Most participants (92%) enrolled in methadone treatment during induction. Drug abstinence increased as a graded function of the addition of the methadone and abstinence contingencies. Abstinence, Methadone & Work Reinforcement participants provided significantly more urine samples negative for opiates (75% versus 54%) and cocaine (57% versus 32%) than Work Reinforcement participants. Methadone & Work Reinforcement participants provided significantly more cocaine-negative samples than Work Reinforcement participants (55% versus 32%)., Conclusion: The therapeutic workplace can promote drug abstinence in out-of-treatment injection drug users.

Background: Drug addiction can be a chronic problem. Abstinence reinforcement can initiate drug abstinence, but as with other treatments many patients relapse after the intervention ends. Abstinence reinforcement can be maintained to promote long-term drug abstinence, but practical means of implementing long-term abstinence reinforcement are needed., Methods: We reviewed 8 clinical trials conducted in Baltimore, MD from 1996 through 2010 that evaluated the therapeutic workplace as a vehicle for maintaining reinforcement for the treatment of drug addiction. The therapeutic workplace uses employment-based reinforcement in which employees must provide objective evidence of drug abstinence or medication adherence to work and earn wages., Results: Employment-based reinforcement can initiate (3 of 4 studies) and maintain (2 studies) cocaine abstinence in methadone patients, although relapse can occur even after long-term exposure to abstinence reinforcement (1 study). Employment-based reinforcement can also promote abstinence from alcohol in homeless alcohol dependent adults (1 study), and maintain adherence to extended-release naltrexone in opioid dependent adults (2 studies)., Conclusion: Treatments should seek to promote life-long effects in patients. Therapeutic reinforcement may need to be maintained indefinitely to prevent relapse. Workplaces could be effective vehicles for the maintenance of therapeutic reinforcement contingencies for drug abstinence and adherence to addiction medications., (Copyright © 2012 Elsevier Inc.

Aims: To conduct a randomized, controlled trial of abstinence-contingent recovery housing delivered with or without intensive day treatment among individuals exiting residential opioid detoxification., Design: Random assignment to one of three conditions: recovery housing alone (RH), abstinence-contingent recovery housing with reinforcement-based treatment RBT (RH + RBT) or usual care (UC). RH and RH + RBT participants received 12 weeks of paid recovery housing contingent upon drug abstinence. RH + RBT participants also received 26 weeks of RBT, initiated concurrently with recovery housing. Assessments were conducted at 1, 3 and 6 months after treatment enrollment., Setting: Out-patient drug-free substance abuse treatment program in Baltimore, Maryland., Participants: Patients (n = 243) who completed medication-assisted opioid detoxification., Measurements: Primary outcome was drug abstinence (opioid- and cocaine-negative urine and no self-reported opioid or cocaine use in the previous 30 days). Secondary outcomes included abstinence at all time-points (1, 3 and 6 months), days in recovery housing and employment., Findings: Overall rates of drug abstinence were 50% for RH + RBT, 37% for RH and 13% for UC (P < 0.001). At 6 months, RH + RBT participants remained more likely to meet abstinence criteria than UC participants (37% versus 20%, P = 0.016). Length of stay in recovery housing mediated abstinence outcomes and was longer in RH + RBT (49.5 days) than in RH (32.2 days; P < 0.002)., Conclusions: Abstinence-contingent recovery housing improves abstinence in opioid-dependent adults following medication-assisted detoxification. The addition of intensive 'reinforcement-based treatment' behavioural counseling further improves treatment outcomes, in part by promoting longer recovery house stays., (© 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.)

Aims: Due to the chronicity of cocaine dependence, practical and effective maintenance interventions are needed to sustain long-term abstinence. We sought to assess the effects of long-term employment-based reinforcement of cocaine abstinence after discontinuation of the intervention., Design: Participants who initiated sustained opiate and cocaine abstinence during a 6-month abstinence reinforcement and training program worked as data entry operators and were randomly assigned to a group that could work independently of drug use (control, n = 24), or an abstinence-contingent employment (n = 27) group that was required to provide cocaine- and opiate-negative urine samples to work and maintain maximum rate of pay., Setting: A non-profit data entry business., Participants: Unemployed welfare recipients who persistently used cocaine while in methadone treatment., Measurements: Urine samples and self-reports were collected every 6 months for 30 months., Findings: During the employment year, abstinence-contingent employment participants provided significantly more cocaine-negative samples than controls (82.7% and 54.2%; P = 0.01, OR = 4.61). During the follow-up year, the groups had similar rates of cocaine-negative samples (44.2% and 50.0%; P = 0.93) and human immunodeficiency virus risk behaviors. Participants' social, employment, economic and legal conditions were similar in the two groups across all phases of the study., Conclusions: Employment-based reinforcement effectively maintains long-term cocaine abstinence, but many patients relapse to use when the abstinence contingency is discontinued, even after a year of abstinence-contingent employment. Relapse could be prevented in many patients by leaving employment-based abstinence reinforcement in place indefinitely, which could be facilitated by integrating it into typical workplaces., (© 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.)

Context: Due to the chronic nature of cocaine dependence, long-term maintenance treatments may be required to sustain abstinence. Abstinence reinforcement is among the most effective means of initiating cocaine abstinence. Practical and effective means of maintaining abstinence reinforcement programs over time are needed., Objective: To determine whether employment-based abstinence reinforcement can be an effective long-term maintenance intervention for cocaine dependence., Design: Participants (n = 128) were enrolled in a 6-month job skills training and abstinence initiation program. Participants who initiated abstinence, attended regularly and developed needed job skills during the first 6 months were hired as operators in a data entry business and assigned randomly to an employment-only (control, n = 24) or abstinence-contingent employment (n = 27) group., Setting: A non-profit data entry business. Participants Unemployed welfare recipients who used cocaine persistently while enrolled in methadone treatment in Baltimore., Intervention: Abstinence-contingent employment participants received 1 year of employment-based contingency management, in which access to employment was contingent upon provision of drug-free urine samples under routine and then random drug testing. If a participant provided drug-positive urine or failed to provide a mandatory sample, then that participant received a temporary reduction in pay and could not work until urinalysis confirmed recent abstinence., Main Outcome Measure: Cocaine-negative urine samples at monthly assessments across 1 year of employment., Results: During the 1 year of employment, abstinence-contingent employment participants provided significantly more cocaine-negative urine samples than employment-only participants [79.3% and 50.7%, respectively; P = 0.004, odds ratio (OR) = 3.73, 95% confidence interval (CI) = 1.60-8.69]. Conclusions Employment-based abstinence reinforcement that includes random drug testing is effective as a long-term maintenance intervention, and is among the most promising treatments for drug dependence. Work-places could serve as therapeutic agents in the treatment of drug dependence by arranging long-term employment-based contingency management programs.
