Abstract
This study evaluated the effectiveness of abstinence-contingent wage supplements in promoting alcohol abstinence and employment in adults experiencing homelessness and alcohol use disorder. A randomized clinical trial was conducted from 2019 to 2022. After a 1-month Induction period, 119 participants were randomly assigned to a Usual Care Control group (n = 57) or an Abstinence-Contingent Wage Supplement group (n = 62). Usual Care participants were offered counseling and referrals to employment and treatment programs. Abstinence-Contingent Wage Supplement participants could earn stipends for working with an employment specialist and wage supplements for working in a community job but had to maintain abstinence from alcohol as determined by transdermal alcohol concentration monitoring devices to maximize pay. Abstinence-Contingent Wage Supplement participants reported significantly higher rates of alcohol abstinence than Usual Care participants during the 6-month intervention (82.8% vs. 60.2% of months, OR = 3.4, 95% CI 1.8 to 6.3, p < .001). Abstinence-Contingent Wage Supplement participants were also significantly more likely to obtain employment (51.3% vs. 31.6% of months, OR = 2.6, 95% CI 1.5 to 4.4, p < .001) and live out of poverty (38.2% vs. 16.7% of months, OR = 3.7, 95% CI 2.0 to 7.1, p < .001) than Usual Care participants. These findings suggest that Abstinence-Contingent Wage Supplements can promote alcohol abstinence and employment in adults experiencing homelessness and alcohol use disorder.

Abstract
Employment problems are common among people with substance use disorders (SUDs), and improving vocational functioning is an important aspect of SUD treatment. More detailed understanding of the psychosocial benefits of employment may help refine vocational interventions for people with SUDs. Here, we used ecological momentary assessment to measure possible affective improvements associated with work. Participants (n = 161) with opioid use disorder were randomized to work (job-skills training) in a contingency-management-based Therapeutic Workplace either immediately or after a waitlist delay. Throughout, participants responded via smartphone to randomly scheduled questionnaires. In linear mixed models comparing responses made at work vs. all other locations, being at work was associated with: less stress, less craving for opioids and cocaine, less negative mood, more positive mood, and more flow-like states. Some of these differences were also observed on workdays vs. non-workdays outside of work hours. These results indicate that benefits associated with work may not be restricted to being actually in the workplace; however, randomization did not reveal clear changes coinciding with the onset of work access. Overall, in contrast to work-associated negative moods measured by experience-sampling in the general population, Therapeutic Workplace participants experienced several types of affective improvements associated with work.

Abstinence-contingent wage supplements to promote drug abstinence and employment: Post-intervention outcomes. Drug Alcohol Depend 2022; 232:109322. [PMID: 35077956 PMCID: PMC8885832 DOI: 10.1016/j.drugalcdep.2022.109322] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2021] [Revised: 01/17/2022] [Accepted: 01/18/2022] [Indexed: 11/22/2022]
Abstract
BACKGROUND Substance use disorder, unemployment, and poverty are interrelated problems that have not been addressed adequately by existing interventions. This study evaluated post-intervention effects of abstinence-contingent wage supplements on drug abstinence and employment. METHODS Unemployed adults enrolled in opioid agonist treatment were randomly assigned to an abstinence-contingent wage supplement group (n = 44) or a usual care control group (n = 47). All participants could work with an employment specialist throughout a 12-month intervention period. Those in the abstinence-contingent wage supplement group earned stipends for working with the employment specialist and, after gaining employment, abstinence-contingent wage supplements for working in their community job but had to provide opiate- and cocaine-negative urine samples to maximize pay. To assess post-intervention effects of abstinence-contingent wage supplements and compare those effects to during-intervention effects, we analyzed urine samples and self-reports every 3 months during the 12-month intervention and the 12-month post-intervention period. RESULTS During the intervention, abstinence-contingent wage supplement participants provided significantly more opiate- and cocaine-negative urine samples than usual care control participants; abstinence-contingent wage supplement participants were also significantly more likely to become employed and live out of poverty than usual care participants during intervention. During the post-intervention period, the abstinence-contingent wage supplement and usual care control groups had similar rates of drug abstinence, similar levels of employment, and similar proportions living out of poverty. CONCLUSIONS Long-term delivery of abstinence-contingent wage supplements can promote drug abstinence and employment, but many patients relapse to drug use and cease employment when wage supplements are discontinued.

Quality of life during a randomized trial of a therapeutic-workplace intervention for opioid use disorder: Web-based mobile assessments reveal effects of drug abstinence and access to paid work. DRUG AND ALCOHOL DEPENDENCE REPORTS 2021; 1:100011.

Abstract
Background Employment and improved quality of life (QOL) are, separately, valued outcomes of substance use disorder (SUD) treatment. It is also important to understand QOL changes caused by employment itself; therefore, we assessed QOL during a randomized trial of a contingency-management-based Therapeutic Workplace for people with opioid use disorder. Methods For 12 weeks, participants (n = 61) responded to QOL questionnaires in a mobile web app accessed with study-issued smartphones. At enrollment, participants were randomized to work in the Therapeutic Workplace immediately (immediate work group, IWG) or after a 3-week waitlist delay (delayed work group, DWG). Once both groups could work, wage-resetting contingencies were introduced for their opiate- and cocaine-urinalysis. Data were analyzed by (1) access to work with and without contingencies and (2) overall urinalysis-verified opiate- and cocaine-abstinence. Results DWG and/or IWG reported improvements in several QOL areas (sleep, transportation, recreation); however, they also reported increased money-related difficulties and less time spent with friends/family. These changes did not coincide with DWG's work access, but some (more sleep, money-related difficulties) coincided with the urinalysis contingencies. Greater opiate- and/or cocaine-abstinence was also associated with several improvements: sleep, paying bills, time spent with friends/family, and exercising. Surprisingly, intermediate cocaine abstinence was associated with reductions in work-capacity satisfaction and recreation. Conclusions Participants reported complex QOL differences during their experimental employment and associated with drug abstinence. Future work should help participants address issues that may be relevant to employment generally (e.g., time with friends/family) or contingency management specifically (e.g., money-related issues for non-abstinent participants).

Abstract
BACKGROUND Unemployment is a common problem among adults who have substance use disorder that often persists during treatment and recovery. We identified patient characteristics that were associated with obtaining employment among unemployed adults in opioid use disorder treatment. METHODS This analysis used data from participants (N = 91) who were enrolled in a randomized controlled trial evaluating the effectiveness of a therapeutic workplace in promoting drug abstinence and employment. After a 3-month training period (Phase 1), participants were randomly assigned to a study group and could work for 12 months with an employment specialist who assisted participants in obtaining employment (Phase 2). A logistic regression model was used to identify patient characteristics that were associated with obtaining employment. RESULTS Of the 91 participants, 39 (42.9 %) obtained employment. Compared to participants who did not obtain employment, participants who obtained employment worked more days in the therapeutic workplace during the training period (Phase 1) [OR (95 % CI) = 1.072 (1.015-1.132), p = .014], provided more opiate- and cocaine-negative urine samples while seeking employment [OR (95 % CI) = 1.015 (1.002-1.027), p = .025], and reported not usually being unemployed at study intake [OR (95 % CI) = 0.229 (0.080-0.652), p = .007]. CONCLUSIONS Our analyses suggest that among unemployed adults in opioid use disorder treatment, those with the lowest rates of therapeutic workplace attendance, lowest rates of drug abstinence while seeking employment, and relatively long histories of unemployment are the least likely to obtain employment. These relations are potentially addressable at a practical level, and future research could build on these findings to improve the effectiveness of employment-based interventions.

Abstract
The current opioid epidemic has killed more than 446,000 Americans over the past two decades. Despite the magnitude of the crisis, little is known to what degree the misalignment of incentives among stakeholders due to competing interests has contributed to the current situation. In this study, we explore evidence in the literature for the working hypothesis that misalignment rooted in the cost, quality, or access to care can be a significant contributor to the opioid epidemic. The review identified several problems that can contribute to incentive misalignment by compromising the triple aims (cost, quality, and access) in this epidemic. Some of these issues include the inefficacy of conventional payment mechanisms in providing incentives for providers, practice guidelines in pain management that are not easily implementable across different medical specialties, barriers in adopting multi-modal pain management strategies, low capacity of providers/treatments to address opioid/substance use disorders, the complexity of addressing the co-occurrence of chronic pain and opioid use disorders, and patients' non-adherence to opioid substitution treatments. In discussing these issues, we also shed light on factors that can facilitate the alignment of incentives among stakeholders to effectively address the current crisis.

Employment outcomes of substance use disorder patients enrolled in a therapeutic workplace intervention for drug abstinence and employment. J Subst Abuse Treat 2020; 120:108160. [PMID: 33298300 DOI: 10.1016/j.jsat.2020.108160] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2020] [Revised: 08/11/2020] [Accepted: 10/04/2020] [Indexed: 11/20/2022]
Abstract
Poverty is common among people who have substance use disorder. The therapeutic workplace addresses some of the interrelated and chronic problems of poverty, such as unemployment, lack of education and job skills, and drug use. A prior controlled trial showed that the therapeutic workplace was effective in promoting drug abstinence and self-reported community employment in unemployed adults in medication-assisted treatment for opioid use disorder. The current study extends this research by providing a detailed and objective analysis of employment outcomes using objective data abstracted from participants' pay stubs. Secondary analyses examined the types and patterns of employment that participants (N = 44) obtained during the trial, and the extent to which participants gained and maintained financially sufficient employment. Although most participants had relatively long histories of unemployment and underemployment, many participants (n = 26; 59%) obtained employment at some point during the intervention. Most participants worked part time and were employed in low-wage jobs, however. The mean number of hours worked per week was 20.6 h (range 5.5 to 41.3 h per week) and the mean hourly pay was $11.00 per hour (range $9.00 to $15.50 per hour). The most common type of employment was in food preparation and serving-related occupations (e.g., waiters and waitresses, restaurant cooks, and fast food counter workers). Many participants (n = 17; 65%) maintained employment in these jobs over several weeks, while others (n = 9; 35%) were employed sporadically for short durations. Additional supports may be needed for some chronically unemployed adults with substance use disorder to promote consistent employment in well-paying jobs.

Abstract
BACKGROUND Promoting employment among unemployed adults with substance use disorder is a difficult challenge for which existing interventions have had limited effects. This study examined whether financial incentives could increase engagement in employment services for unemployed adults in treatment for opioid use disorder. METHODS The study was conducted from 2014 to 2019 in Baltimore, MD. After a 3-month abstinence initiation and training period, participants (N = 91) were randomly assigned to a Control group or an Incentive group and were invited to work with an employment specialist to seek employment in a community job for 12 months. Participants assigned to the Control group (n = 47) did not receive incentives for working with the employment specialist. Participants assigned to the Incentive group (n = 44) could earn financial incentives for working with the employment specialist, but had to provide opiate- and cocaine-negative urine samples to maximize pay. RESULTS Incentive participants attended the employment services and worked with the employment specialist on significantly more days than Control participants (41.8 % versus 1.1 % of days; OR = 40.42, 95 % CI = 32.46-48.38, p < .001), and for significantly more hours than Control participants (3.58 versus 1.25 h, on average; OR=2.34, 95 % CI=1.83-2.85, p < .001). Incentive participants were more likely to be retained than Control participants when analyses were based solely on attendance (HR=0.12, 95 % CI=0.06-0.25, p < .001) and attendance and employment combined (HR=0.15, 95 % CI=0.07-0.31, p < .001). CONCLUSIONS Financial incentives were effective in promoting engagement in employment services for individuals who often do not utilize employment services.

Abstract
BACKGROUND Poverty, unemployment and substance abuse are inter-related problems. This study evaluated the effectiveness of abstinence-contingent wage supplements in promoting drug abstinence and employment in unemployed adults in outpatient treatment for opioid use disorder. METHODS A randomised controlled trial was conducted in Baltimore, MD, from 2014 to 2019. After a 3-month abstinence initiation and training period, participants (n=91) were randomly assigned to a usual care control group that received employment services or to an abstinence-contingent wage supplement group that received employment services plus abstinence-contingent wage supplements. All participants were invited to work with an employment specialist to seek employment in a community job for 12 months. Abstinence-contingent wage supplement participants could earn training stipends for working with the employment specialist and wage supplements for working in a community job, but had to provide opiate and cocaine-negative urine samples to maximise pay. RESULTS Abstinence-contingent wage supplement participants provided significantly more opiate and cocaine-negative urine samples than usual care control participants (65% vs 45%; OR=2.29, 95% CI 1.22 to 4.30, p=0.01) during the 12-month intervention. Abstinence-contingent wage supplement participants were significantly more likely to have obtained employment (59% vs 28%; OR=3.88, 95% CI 1.60 to 9.41, p=0.004) and lived out of poverty (61% vs 30%; OR=3.77, 95% CI 1.57 to 9.04, p=0.004) by the end of the 12-month intervention than usual care control participants. CONCLUSION Abstinence-contingent wage supplements can promote drug abstinence and employment. TRIAL REGISTRATION NUMBER ClinicalTrials.gov NCT02487745.
