Abstract
Background Homelessness is a traumatic experience, and can have a devastating effect on those experiencing it. People who are homeless often face significant barriers when accessing public services, and have often experienced adverse childhood events, extreme social disadvantage, physical, emotional and sexual abuse, neglect, low self-esteem, poor physical and mental health, and much lower life expectancy compared to the general population. Rates of problematic substance use are disproportionately high, with many using drugs and alcohol to deal with the stress of living on the street, to keep warm, or to block out memories of previous abuse or trauma. Substance dependency can also create barriers to successful transition to stable housing. Objectives To understand the effectiveness of different substance use interventions for adults experiencing homelessness. Search Methods The primary source of studies for was the 4th edition of the Homelessness Effectiveness Studies Evidence and Gaps Maps (EGM). Searches for the EGM were completed in September 2021. Other potential studies were identified through a call for grey evidence, hand-searching key journals, and unpacking relevant systematic reviews. Selection Criteria Eligible studies were impact evaluations that involved some comparison group. We included studies that tested the effectiveness of substance use interventions, and measured substance use outcomes, for adults experiencing homelessness in high income countries. Data Collection and Analysis Descriptive characteristics and statistical information in included studies were coded and checked by at least two members of the review team. Studies selected for the review were assessed for confidence in the findings. Standardised effect sizes were calculated and, if a study did not provide sufficient raw data for the calculation of an effect size, author(s) were contacted to obtain these data. We used random-effects meta-analysis and robust-variance estimation procedures to synthesise effect sizes. If a study included multiple effects, we carried out a critical assessment to determine (even if only theoretically) whether the effects are likely to be dependent. Where dependent effects were identified, we used robust variance estimation to determine whether we can account for these. Where effect sizes were converted from a binary to continuous measure (or vice versa), we undertook a sensitivity analysis by running an additional analysis with these studies omitted. We also assessed the sensitivity of results to inclusion of non-randomised studies and studies classified as low confidence in findings. All included an assessment of statistical heterogeneity. Finally, we undertook analysis to assess whether publication bias was likely to be a factor in our findings. For those studies that we were unable to include in meta-analysis, we have provided a narrative synthesis of the study and its findings. Main Results We included 48 individual papers covering 34 unique studies. The studies covered 15, 255 participants, with all but one of the studies being from the United States and Canada. Most papers were rated as low confidence (n = 25, or 52%). By far the most common reason for studies being rated as low confidence was high rates of attrition and/or differential attrition of study participants, that fell below the What Works Clearinghouse liberal attrition standard. Eleven of the included studies were rated as medium confidence and 12 studies as high confidence. The interventions included in our analysis were more effective in reducing substance use than treatment as usual, with an overall effect size of -0.11 SD (95% confidence interval [CI], -0.27, 0.05). There was substantial heterogeneity across studies, and the results were sensitive to the removal of low confidence studies (-0.21 SD, 95% CI [-0.59, 0.17] - 6 studies, 17 effect sizes), the removal of quasi-experimental studies (-0.14 SD, 95% CI [-0.30, 0.02] - 14 studies, 41 effect sizes) and the removal of studies where an effect size had been converted from a binary to a continuous outcome (-0.08 SD, 95% CI [-0.31, 0.15] - 10 studies, 31 effect sizes). This suggests that the findings are sensitive to the inclusion of lower quality studies, although unusually the average effect increases when we removed low confidence studies. The average effect for abstinence-based interventions compared to treatment-as-usual (TAU) service provision was -0.28 SD (95% CI, -0.65, 0.09) (6 studies, 15 effect sizes), and for harm reduction interventions compared to a TAU service provision is close to 0 at 0.03 SD (95% CI, -0.08, 0.14) (9 studies, 30 effect sizes). The confidence intervals for both estimates are wide and crossing zero. For both, the comparison groups are primarily abstinence-based, with the exception of two studies where the comparison group condition was unclear. We found that both Assertative Community Treatment and Intensive Case Management were no better than treatment as usual, with average effect on substance use of 0.03 SD, 95% CI [-0.07, 0.13] and -0.47 SD, 95% CI [-0.72, -0.21] 0.05 SD, 95% CI [-0.28, 0.39] respectively. These findings are consistent with wider research, and it is important to note that we only examined the effect on substance use outcomes (these interventions can be effective in terms of other outcomes). We found that CM interventions can be effective in reducing substance use compared to treatment as usual, with an average effect of -0.47 SD, 95% CI (-0.72, -0.21). All of these results need to be considered in light of the quality of the underlying evidence. There were six further interventions where we undertook narrative synthesis. These syntheses suggest that Group Work, Harm Reduction Psychotherapy, and Therapeutic Communities are effective in reducing substance use, with mixed results found for Motivational Interviewing and Talking Therapies (including Cognitive Behavioural Therapy). The narrative synthesis suggested that Residential Rehabilitation was no better than treatment as usual in terms of reducing substance use for our population of interest. Authors' Conclusions Although our analysis of harm reduction versus treatment as usual, abstinence versus treatment as usual, and harm reduction versus abstinence suggests that these different approaches make little real difference to the outcomes achieved in comparison to treatment as usual. The findings suggest that some individual interventions are more effective than others. The overall low quality of the primary studies suggests that further primary impact research could be beneficial.

Improving oral health and related health behaviours (substance use, smoking, diet) in people with severe and multiple disadvantage: A systematic review of effectiveness and cost-effectiveness of interventions. PLoS One 2024; 19:e0298885. [PMID: 38635524 PMCID: PMC11025870 DOI: 10.1371/journal.pone.0298885] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Accepted: 01/31/2024] [Indexed: 04/20/2024] Open
Abstract
BACKGROUND People experiencing homelessness co-occurring with substance use or offending ('severe and multiple disadvantage' SMD) often have high levels of poor oral health and related health behaviours (particularly, substance use, smoking, poor diet). This systematic review aimed to assess the effectiveness and cost-effectiveness of interventions in adults experiencing SMD to improve oral health and related health behaviours. METHODS AND FINDINGS From inception to February 2023, five bibliographic databases (MEDLINE, EMBASE, PsycINFO, CINAHL, and Scopus) and grey literature were searched. Two researchers independently screened the search results. Randomized controlled trials (RCTs), comparative studies and economic evaluations were included that reported outcomes on oral health and the related health behaviours. Risk of bias was assessed and results narratively synthesized. Meta-analyses were performed where appropriate. This review was registered with PROSPERO (reg. no: CRD42020202416). Thirty-eight studies were included (published between 1991 and 2023) with 34 studies reporting about effectiveness. Most studies reported on substance use (n = 30). Interventions with a combination of housing support with substance use and mental health support such as contingent work therapy appeared to show some reduction in substance use in SMD groups. However, meta-analyses showed no statistically significant results. Most studies had short periods of follow-up and high attrition rates. Only one study reported on oral health; none reported on diet. Three RCTs reported on smoking, of which one comprising nicotine replacement with contingency management showed improved smoking abstinence at 4 weeks compared to control. Five studies with economic evaluations provided some evidence that interventions such as Housing First and enhanced support could be cost-effective in reducing substance use. CONCLUSION This review found that services such as housing combined with other healthcare services could be effective in improving health behaviours, particularly substance use, among SMD groups. Gaps in evidence also remain on oral health improvement, smoking, and diet. High quality studies on effectiveness with adequate power and retention are needed to address these significant health challenges in SMD populations.

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
BACKGROUND The evidence-based Therapeutic Workplace (TWP) is a promising employment-based treatment where access to work is contingent on objective evidence of abstinence from drugs. TWP is sometimes criticized for requiring individuals who use drugs to voluntarily enroll in a program requiring urine drug testing. OBJECTIVE This experiment was conducted to assess whether urine drug testing as a condition of employment decreases the value of employment opportunities and to what degree. METHODS Participants were unemployed, DSM-IV opioid-dependent, and enrolled in TWP. Participants completed discounting tasks assessing preference for a hypothetical job paying a constant wage that did not require urine drug testing and a job that paid a variable wage but required drug testing. The primary outcome was 'job value' operationalized as percentage wage difference to accept a job requiring urine drug testing. RESULTS Percent wage difference to accept a job that required urine testing was analyzed using GEE. Results revealed a significant main effect of recent drug use (χ2(1) = 10.07, p < .01). CONCLUSION Most participants were willing to accept a urine drug-testing job across wages similar non-drug testing jobs. Participants reporting recent cocaine or heroin use were less likely to choose urine drug-testing employment.

Abstract
Background Adequate housing is a basic human right. The many millions of people experiencing homelessness (PEH) have a lower life expectancy and more physical and mental health problems. Practical and effective interventions to provide appropriate housing are a public health priority. Objectives To summarise the best available evidence relating to the components of case-management interventions for PEH via a mixed methods review that explored both the effectiveness of interventions and factors that may influence its impact. Search Methods We searched 10 bibliographic databases from 1990 to March 2021. We also included studies from Campbell Collaboration Evidence and Gap Maps and searched 28 web sites. Reference lists of included papers and systematic reviews were examined and experts contacted for additional studies. Selection Criteria We included all randomised and non-randomised study designs exploring case management interventions where a comparison group was used. The primary outcome of interest was homelessness. Secondary outcomes included health, wellbeing, employment and costs. We also included all studies where data were collected on views and experiences that may impact on implementation. Data Collection and Analysis We assessed risk of bias using tools developed by the Campbell Collaboration. We conducted meta-analyses of the intervention studies where possible and carried out a framework synthesis of a set of implementation studies identified by purposive sampling to represent the most 'rich' and 'thick' data. Main Results We included 64 intervention studies and 41 implementation studies. The evidence base was dominated by studies from the USA and Canada. Participants were largely (though not exclusively) people who were literally homeless, that is, living on the streets or in shelters, and who had additional support needs. Many studies were assessed as having a medium or high risk of bias. However, there was some consistency in outcomes across studies that improved confidence in the main findings. Case Management and Housing Outcomes Case management of any description was superior to usual care for homelessness outcomes (standardised mean difference [SMD] = -0.51 [95% confidence interval [CI]: -0.71, -0.30]; p < 0.01). For studies included in the meta-analyses, Housing First had the largest observed impact, followed by Assertive Community Treatment, Critical Time Intervention and Intensive Case Management. The only statistically significant difference was between Housing First and Intensive Case Management (SMD = -0.6 [-1.1, -0.1]; p = 0.03) at ≥12 months. There was not enough evidence to compare the above approaches with standard case management within the meta-analyses. A narrative comparison across all studies was inconclusive, though suggestive of a trend in favour of more intensive approaches. Case Management and Mental Health Outcomes The overall evidence suggested that case management of any description was not more or less effective compared to usual care for an individual's mental health (SMD = 0.02 [-0.15, 0.18]; p = 0.817). Case Management and Other Outcomes Based on meta-analyses, case management was superior to usual care for capability and wellbeing outcomes up to 1 year (an improvement of around one-third of an SMD; p < 0.01) but was not statistically significantly different for substance use outcomes, physical health, and employment. Case Management Components For homelessness outcomes, there was a non-significant trend for benefits to be greater in the medium term (≤3 years) compared to long term (>3 years) (SMD = -0.64 [-1.04, -0.24] vs. -0.27 [-0.53, 0]; p = 0.16) and for in-person meetings in comparison to mixed (in-person and remote) approaches (SMD = -0.73 [-1.25,-0.21]) versus -0.26 [-0.5,-0.02]; p = 0.13). There was no evidence from meta-analyses to suggest that an individual case manager led to better outcomes then a team, and interventions with no dedicated case manager may have better outcomes than those with a named case manager (SMD = -0.36 [-0.55, -0.18] vs. -1.00 [-2.00, 0.00]; p = 0.02). There was not enough evidence from meta-analysis to assess whether the case manager should have a professional qualification, or if frequency of contact, case manager availability or conditionality (barriers due to conditions attached to service provision) influenced outcomes. However, the main theme from implementation studies concerned barriers where conditions were attached to services. Characteristics of Persons Experiencing Homelessness No conclusions could be drawn from meta-analysis other than a trend for greater reductions in homelessness for persons with high complexity of need (two or more support needs in addition to homelessness) as compared to those with medium complexity of need (one additional support need); effect sizes were SMD = -0.61 [-0.91, -0.31] versus -0.36 [-0.68, -0.05]; p = 0.3. The Broader Context of Delivery of Case Management Programmes Other major themes from the implementation studies included the importance of interagency partnership; provision for non-housing support and training needs of PEH (such as independent living skills), intensive community support following the move to new housing; emotional support and training needs of case managers; and an emphasis on housing safety, security and choice. Cost Effectiveness The 12 studies with cost data provided contrasting results and no clear conclusions. Some case management costs may be largely off-set by reductions in the use of other services. Cost estimates from three North American studies were $45-52 for each additional day housed. Authors' Conclusions Case management interventions improve housing outcomes for PEH with one or more additional support needs, with more intense interventions leading to greater benefits. Those with greater support needs may gain greater benefit. There is also evidence for improvements to capabilities and wellbeing. Current approaches do not appear to lead to mental health benefits. In terms of case management components, there is evidence in support of a team approach and in-person meetings and, from the implementation evidence, that conditions associated with service provision should be minimised. The approach within Housing First could explain the finding that overall benefits may be greater than for other types of case management. Four of its principles were identified as key themes within the implementation studies: No conditionality, offer choice, provide an individualised approach and support community building. Recommendations for further research include an expansion of the research base outside North America and further exploration of case management components and intervention cost-effectiveness.

Effectiveness of employment-based interventions for persons experiencing homelessness: A systematic review. HEALTH & SOCIAL CARE IN THE COMMUNITY 2022; 30:2142-2169. [PMID: 35748222 DOI: 10.1111/hsc.13892] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Revised: 05/26/2022] [Accepted: 06/04/2022] [Indexed: 06/15/2023]
Abstract
Employment is frequently desired by persons who experience homelessness yet is often elusive. Little is known about the range and effectiveness of employment-based interventions evaluated in existing literature on key psychosocial outcomes including employment participation, mental well-being, housing tenure, community integration and substance use. To identify and synthesise existing studies, we conducted a systematic review of effectiveness using the methodology proposed by the Joanna Briggs Institute (JBI) following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Following the removal of duplicates, we screened 13,398 titles and abstracts, and reviewed 79 studies at the full-text review stage using two independent raters. A total of 16 studies met criteria for inclusion in a narrative synthesis and were subjected to critical appraisal. The majority of studies were conducted in the US (n = 14; 87.5%) with other studies published in Canada (n = 1; 6.3%) and Australia (n = 1; 6.3%). Interventions evaluated in existing studies included combined substance use and vocational skills interventions (n = 7; 43.8%), supported employment (n = 6; 37.5%), and integrated supports including an employment component (n = 3; 18.8%). The effectiveness of these interventions on employment, mental well-being, housing tenure, community integration, and substance use is presented. Findings suggest that research evaluating employment interventions for persons who experience homelessness is in an early stage of development. Researchers and practitioners may consider collaborating with persons with lived experiences of homelessness and practitioners in co-designing and modifying existing approaches to target key outcomes more effectively. Policymakers may consider allocating resources to such initiatives to further the development of practice and research aimed at supporting persons who experience homelessness to secure and sustain employment during and following homelessness.

Using financial incentives to improve health service engagement and outcomes of adults experiencing homelessness: A scoping review of the literature. HEALTH & SOCIAL CARE IN THE COMMUNITY 2022; 30:e3406-e3434. [PMID: 35912903 DOI: 10.1111/hsc.13944] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/14/2022] [Revised: 05/26/2022] [Accepted: 07/04/2022] [Indexed: 06/15/2023]
Abstract
People experiencing homelessness (PEH) have high rates of acute and chronic health conditions, complex support needs and often face multiple barriers to accessing health services. Financial incentive (FI) interventions have been found effective in improving service engagement and health outcomes for a range of health conditions, populations and settings, but little is known about their impact on PEH. We conducted a scoping review to explore the impact of FI interventions on treatment retention, adherence and other health outcomes of PEH. We searched seven electronic databases from inception to September 2021 to identify peer-reviewed published English language studies that used FI interventions with adult PEH. A scoping review methodology was used to chart relevant data uniformly. Descriptive statistics and narrative syntheses were used to describe outcomes. Thirty-three quantitative articles related to 29 primary studies were published between 1990 and 2021 and met inclusion criteria. Studies targeted three areas of health behaviour change: decreasing substance use or increasing abstinence rates, preventing or treating infectious diseases or promoting lifestyle/general health goal attainment. A variety of FIs were used (cash/non-cash, escalating/fixed schedule, larger/smaller amounts, some/all behaviours rewarded, certain/uncertain reward) across studies. Twenty-six of the primary studies reported significantly better outcomes for the participants receiving FI compared to controls. There were mixed findings about the efficacy of cash versus non-cash FIs, non-cash FIs versus other interventions and higher versus lower value of incentives. Furthermore, there was limited research about long-term outcomes and impacts. FIs have promise in increasing abstinence from substances, engagement in infectious disease treatment, retention in health services and general lifestyle modifications for PEH. Future research should examine long-term impacts and the contribution of co-interventions and intermediary lifestyle behaviour changes.

Abstract
The delivery of monetary incentives contingent on verified abstinence is an effective treatment for alcohol use disorder. However, incentive cost has often been cited as a barrier to delivering this type of treatment. In the present randomized parallel groups trial, we systematically replicated a previous trial we conducted that employed remote alcohol monitoring and incentive delivery to promote abstinence from alcohol, but with the additional requirement for participants to partially self-fund their abstinence incentives. Treatment-seeking participants with alcohol use disorder (n = 92) who met inclusion criteria (n = 36) were randomized to either a Contingent or Noncontingent group (n = 18 each). Those not meeting inclusion criteria included 15 participants who agreed to the deposit requirement but failed to make the deposit payment. The Contingent group received nearly immediate monetary incentives each day they remotely provided negative breathalyzer samples. The Noncontingent group received matched incentives each day they successfully provided samples independent of alcohol content. Days abstinent in the Contingent group were 86%, which was significantly higher than the 44% recorded in the Noncontingent group, corresponding to an odds ratio of 8.2. Exploratory analyses revealed that the deposit requirement prevented participation in those with lower incomes and those with greater alcohol use. These results support the efficacy of this remotely deliverable alcohol abstinence reinforcement incentive intervention with a deposit requirement. However, the requirement to provide a monetary deposit to self-fund abstinence incentives may prevent those with greater alcohol use and/or those experiencing extreme poverty from participating in the intervention.

Effect of Incentives for Alcohol Abstinence in Partnership With 3 American Indian and Alaska Native Communities: A Randomized Clinical Trial. JAMA Psychiatry 2021; 78:599-606. [PMID: 33656561 PMCID: PMC7931140 DOI: 10.1001/jamapsychiatry.2020.4768] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Accepted: 12/18/2020] [Indexed: 12/28/2022]
Abstract
Importance Many American Indian and Alaska Native communities are disproportionately affected by problems with alcohol use and seek culturally appropriate and effective interventions for individuals with alcohol use disorders. Objective To determine whether a culturally tailored contingency management intervention, in which incentives were offered for biologically verified alcohol abstinence, resulted in increased abstinence among American Indian and Alaska Native adults. This study hypothesized that adults assigned to receive a contingency management intervention would have higher levels of alcohol abstinence than those assigned to the control condition. Design, Setting, and Participants This multisite randomized clinical trial, the Helping Our Native Ongoing Recovery (HONOR) study, included a 1-month observation period before randomization and a 3-month intervention period. The study was conducted at 3 American Indian and Alaska Native health care organizations located in Alaska, the Pacific Northwest, and the Northern Plains from October 10, 2014, to September 2, 2019. Recruitment occurred between October 10, 2014, and February 20, 2019. Eligible participants were American Indian or Alaska Native adults who had 1 or more days of high alcohol-use episodes within the last 30 days and a current diagnosis of alcohol dependence. Data were analyzed from February 1 to April 29, 2020. Interventions Participants received treatment as usual and were randomized to either the contingency management group, in which individuals received 12 weeks of incentives for submitting a urine sample indicating alcohol abstinence, or the control group, in which individuals received 12 weeks of incentives for submitting a urine sample without the requirement of alcohol abstinence. Regression models fit with generalized estimating equations were used to assess differences in abstinence during the intervention period. Main Outcomes and Measures Alcohol-negative ethyl glucuronide (EtG) urine test result (defined as EtG<150 ng/mL). Results Among 1003 adults screened for eligibility, 400 individuals met the initial criteria. Of those, 158 individuals (39.5%; mean [SD] age, 42.1 [11.4] years; 83 men [52.5%]) met the criteria for randomization, which required submission of 4 or more urine samples and 1 alcohol-positive urine test result during the observation period before randomization. A total of 75 participants (47.5%) were randomized to the contingency management group, and 83 participants (52.5%) were randomized to the control group. At 16 weeks, the number who submitted an alcohol-negative urine sample was 19 (59.4%) in the intervention group vs 18 (38.3%) in the control group. Participants randomized to the contingency management group had a higher likelihood of submitting an alcohol-negative urine sample (averaged over time) compared with those randomized to the control group (odds ratio, 1.70; 95% CI, 1.05-2.76; P = .03). Conclusions and Relevance The study's findings indicate that contingency management may be an effective strategy for increasing alcohol abstinence and a tool that can be used by American Indian and Alaska Native communities for the treatment of individuals with alcohol use disorders. Trial Registration ClinicalTrials.gov Identifier: NCT02174315.

The rewarding recovery study: a randomized controlled trial of incentives for alcohol and drug abstinence with a rural American Indian community. Addiction 2020; 116:1569-1579.

Abstract
AIMS To test if contingency management (CM) interventions for alcohol and drug abstinence were associated with increased alcohol and drug abstinence among American Indian adults with alcohol dependence who also use drugs. DESIGN In this 2 × 2 factorial randomized controlled trial, American Indian adults with alcohol dependence who also used drugs were randomized to four conditions: (1) incentives for submission of urine samples only (control condition), (2) CM incentives for alcohol abstinence, (3) CM incentives for drug abstinence or (4) CM incentives for abstinence from both alcohol and drugs. SETTING A Northern Plains Reservation in the United States. PARTICIPANTS A total of 114 American Indian adults aged 35.8 years (standard deviation = 10.4); 49.1% were male. INTERVENTION AND COMPARATOR Participants received incentives if they demonstrated abstinence from alcohol (CM for alcohol, n = 30), abstinence from their most frequently used drug (CM for drugs, n = 27) or abstinence from both alcohol and their most frequently used drug (CM for alcohol and drugs, n = 32) as assessed by urine tests. Controls (n = 25) received incentives for submitting urine samples only. MEASUREMENTS Primary outcomes were urine ethyl glucuronide (alcohol) and drug tests conducted three times per week during the 12-week intervention period. Data analyses included listwise deletion and multiple imputation to account for missing data. FINDINGS The three CM groups were significantly (P < 0.05) more likely to submit alcohol-abstinent urine samples compared with the control condition, with odds ratios ranging from 2.4 to 4.8. The CM for drugs (OR = 3.2) and CM for alcohol and drugs (OR = 2.5) were significantly more likely to submit urine samples that indicated drug abstinence, relative to the control condition (P < 0.05). However, these differences were not significant in multiple imputation analyses (P > 0.05). CONCLUSIONS Contingency management (CM) incentives for abstinence were associated with increased alcohol abstinence in American Indian adults diagnosed with alcohol dependence who also used drugs, living on a rural reservation. The effect of CM incentives on drug abstinence was inconclusive.

Abstract
Alcohol consumption was associated with 3 million deaths worldwide in 2016. Although community action has proven to be effective and has become a priority area of the global strategy to reduce alcohol consumption, there is a gap in the knowledge of community interventions to reduce alcohol use among adults. This study aims to analyze the evidence on effective community-based interventions to reduce alcohol consumption and harm among adults and to identify their components and underlying theories. Search strategy involved five databases (January 2000-March 2020). We included multicomponent, evaluated, and community interventions addressing to adults in urban settings of high-income countries. Furthermore, two conceptual frameworks were adapted to identify the social determinants of alcohol related harms and modifiable factors through community interventions. The initial search yielded 164 articles. The final sample included eight primary studies. Six of them were effective and shared three components (community mobilization; law enforcement and media campaigns), they combined approaches at individual and environmental levels addressing structural determinants of health and some cultural aspects related to consumption. Health outcomes focused mainly on reducing consumption, modifying patterns and acute effects on health. Few studies addressed social problems arising from harmful consumption. This review has identified several effective community-based interventions to reduce harmful use of alcohol among adults as well as some mechanisms and theories supporting them. It also provides a framework to guide new designs, with potential evidence of factors, as well as possible combinations of methods to improve health at community level across different settings and contexts.

Abstract
Polydrug use is a common problem among patients in opioid-substitution treatment. Polydrug use has been reduced by administering abstinence-reinforcement contingencies in a sequence, such that a single drug is targeted until abstinence is achieved, and then an additional drug is targeted. The present study examined effects of administering abstinence-reinforcement contingencies sequentially based on time rather than on achieved abstinence. Participants accessed paid work (about $10/hr maximum) in the Therapeutic Workplace by providing urine samples 3 times per week. The urine samples were tested for opiates and cocaine. During an induction period, participants earned maximum pay independent of drug abstinence. Then, maximum pay depended upon urine samples that were negative for opiates. Two weeks later, maximum pay depended upon urine samples that were negative for both opiates and cocaine. Opiate and cocaine abstinence increased following administration of the respective contingencies. The time-based administration of abstinence reinforcement increased opiate and cocaine abstinence.

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.

Abstract
Resurgence may be a mechanism of relapse in alcohol use disorder patients upon discharge from treatment as part of an abuse-treatment-relapse cycle. Adjunctive pharmacotherapies may be a means to facilitate behavioral treatments and block resurgence. Experiments were conducted using a model of alcohol self-administration to assess the repeatability of the elimination and resurgence of alcohol-maintained behavior and the effects of naltrexone. Experiments had three phases. In Phase 1, behavior was maintained by oral alcohol under a fixed-ratio schedule. In Phase 2, behavior was extinguished via condensed milk delivery under a differential-reinforcement-of-other-behavior (DRO) schedule. In Phase 3, the DRO schedule was eliminated. In Experiment 1, this 3-phase cycle was replicated 4 times. Across replications, response rates and dose of alcohol consumed did not differ in Phase 1, alcohol-maintained behavior was eliminated more rapidly in Phase 2, and the resurgence effect was generally stable in Phase 3. In Experiment 2, naltrexone was administered in Phase 2, Phase 3, or both Phases 2 and 3, to separate groups of rats. Naltrexone facilitated the elimination of alcohol-maintained behavior in Phase 2 and, the resurgence of alcohol-maintained behavior was reduced only for those rats that received naltrexone in both phases. Together, these experiments demonstrate that the resurgence of alcohol-maintained behavior is replicable within-subjects and, further, resurgence of alcohol-maintained behavior may be a useful model to evaluate pharmacological interventions to facilitate behavioral treatments and reduce the likelihood of relapse. Results with naltrexone support the use of medication-assisted therapy approaches to reduce relapse risk in patients. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

Abstract
Addiction to drug and alcohol is regarded as a major health problem worldwide for which available treatments show limited effectiveness. The biggest challenge remains to enhance the capacities of interventions to reduce craving, prevent relapse and promote long-term recovery. New strategies to meet these challenges are being explored. Findings from preclinical work suggest that environmental enrichment (EE) holds therapeutic potential for the treatment of substance use disorders, as demonstrated in a number of animal models of drug abuse. The EE intervention introduced after drug exposure leads to attenuation of compulsive drug taking, attenuation of the rewarding (and reinforcing) effects of drugs, reductions in control of behavior by drug cues, and, very importantly, relapse prevention. Clinical work also suggests that multidimensional EE interventions (involving physical activity, social interaction, vocational training, recreational and community involvement) might produce similar therapeutic effects, if implemented continuously and rigorously. In this review we survey preclinical and clinical studies assessing the efficacy of EE as a behavioral intervention for substance use disorders and address related challenges. We also review work providing empirical evidence for EE-induced neuroplasticity within the mesocorticolimbic system that is believed to contribute to the seemingly therapeutic effects of EE on drug and alcohol-related behaviors.

Abstract
ISSUE ADDRESSED Problematic alcohol consumption (PAC) affects one-third of homeless Australians, and it is expected that the rates will increase as the population ages. However, current policy does not recognise the importance of this problem. The aim of this narrative review was to examine the social determinants and other risk factors contributing to PAC in homeless Australians, the barriers to receiving help and possible solutions for the Australian context. METHODS PubMed and PsycINFO databases and Australian government websites were examined for the keywords "alcohol" and "homeless," and pertinent articles were selected for inclusion and for citation tracking of further relevant articles. RESULTS The causes of PAC in homeless Australians are multifactorial, and multidirectional, and include risk factors such as low socio-economic status, mental illness and having experienced trauma. There is significant stigma associated with both homelessness and PAC, which further isolates this group. Current policies to address PAC in the homeless are inadequate; however, there are a range of possible programs to reduce PAC in this group, and international harm reduction strategies have also shown success in improving outcomes for this group. CONCLUSION There are numerous social risk factors that influence the development of PAC in the homeless. The introduction of harm reduction strategies, programs to enhance motivation and personal skills, as well as better mental health treatment, would all fill important gaps in services for homeless Australians with PAC. SO WHAT?: Health professionals can be advised that there are many social determinants that influence PAC in homeless Australians. There are important structural barriers to providing this marginalised group with the services they require; however, there is scope for the introduction of new programs, including harm reduction strategies, to meet the fundamental needs of this group.

Abstract
Poverty is associated with poor health. This article reviews research on proximal and distal operant interventions to address drug addiction and poverty. Proximal interventions promote health behaviors directly. Abstinence reinforcement, a common proximal intervention for the treatment of drug addiction, can be effective. Manipulating familiar parameters of operant conditioning can improve the effectiveness of abstinence reinforcement. Increasing reinforcement magnitude can increase the proportion of individuals that respond to abstinence reinforcement, arranging long-term exposure to abstinence reinforcement can prevent relapse, and arranging abstinence reinforcement sequentially across drugs can promote abstinence from multiple drugs. Distal interventions reduce risk factors that underlie poor health and may have an indirect beneficial effect on health. In the case of poverty, distal interventions seek to move people out of poverty. The therapeutic workplace includes both proximal and distal interventions to treat drug addiction and poverty. In the therapeutic workplace, participants earn stipends or wages to work. The therapeutic workplace uses employment-based reinforcement in which participants are required to provide drug-free urine samples or take scheduled doses of addiction medications to work and/or maintain maximum pay. The therapeutic workplace has two phases, a training and an employment phase. Special contingencies appear required to promote skill development during the training phase, employment-based reinforcement can promote abstinence from heroin and cocaine and adherence to naltrexone, and the therapeutic workplace can increase employment. Behavior analysts are well-suited to address both poverty and drug addiction using operant interventions like the therapeutic workplace.

Abstract
Poverty is associated with poor health and affects many United States residents. The therapeutic workplace, an operant intervention designed to treat unemployed adults with histories of drug addiction, could form the basis for an effective antipoverty program. Under the therapeutic workplace, participants receive pay for work. To promote drug abstinence or medication adherence, participants must provide drug-free urine samples or take scheduled doses of medication, respectively, to maintain maximum pay. Therapeutic workplace participants receive job-skills training in Phase 1 and perform income-producing jobs in Phase 2. Many unemployed, drug-addicted adults lack skills they would need to obtain high-skilled and high-paying jobs. Many of these individuals attend therapeutic workplace training reliably, but only when offered stipends for attendance. They also work on training programs reliably, but only when they earn stipends for performance on training programs. A therapeutic workplace social business can promote employment, although special contingencies may be needed to ensure that participants are punctual and work entire work shifts, and social businesses do not reliably promote community employment. Therapeutic workplace participants work with an employment specialist to seek community employment, but primarily when they earn financial incentives. Reducing poverty is more challenging than promoting employment, because it requires promoting employment in higher paying, full-time and steady jobs. Although a daunting challenge, promoting the type of employment needed to reduce poverty is an important goal, both because of the obvious benefit in reducing poverty itself and in the potential secondary benefit of reducing poverty-related health disparities.

Abstract
Background The delivery of monetary incentives contingent on verified abstinence is an effective treatment for alcohol use disorder. However, technological barriers to accurate, frequent biochemical verification of alcohol abstinence have limited the dissemination of this technique. Methods In the present randomized parallel trial, we employed a breathalyzer that allows remote, user‐verified collection of a breath alcohol sample, text messaging, and reloadable debit cards for remote delivery of incentives to evaluate a contingency management treatment for alcohol use disorder that can be delivered with no in‐person contact. Treatment‐seeking participants with alcohol use disorder (n = 40) were recruited from the community and randomized to either a contingent or a noncontingent group (n = 20 each). The contingent group received nearly immediate monetary incentives each day they remotely provided negative breathalyzer samples. The noncontingent group received matched monetary payments each day they successfully provided samples independent of alcohol content. Groups were not masked as awareness of group contingencies was an essential intervention component. Results The primary outcome of the intent‐to‐treat analyses (analyzed n = 40) was percent days abstinent as measured by the remote breathalyzer samples. Abstinence rates in the contingent group were 85%, which was significantly higher than the 38% recorded in the noncontingent group, corresponding to an odds ratio of 9.4 (95% CI = 4.0 to 22.2). Breathalyzer collection adherence rates were over 95%, and participant ratings of acceptability were also high. Conclusions These results support the efficacy, acceptability, and feasibility of this remotely deliverable abstinence reinforcement incentive intervention for the initiation and near‐term maintenance of abstinence from alcohol in adults with alcohol use disorder. Due to low provider and participant burden, this procedure has the potential for broad dissemination.

Abstract
BACKGROUND Adults experiencing homelessness and serious mental illnesses (SMI) are at an increased risk of poor mental health and treatment outcomes compared with stably housed adults with SMI. The additional issue of alcohol misuse further complicates the difficulties of those living with homelessness and SMI. In this secondary data analysis, the authors investigated the impact of homelessness on attrition and alcohol use in a contingency management (CM) intervention that rewarded alcohol abstinence in outpatients with SMI. METHODS The associations between housing status and attrition and alcohol abstinence during treatment, as assessed by ethyl glucuronide (EtG) urine tests, were evaluated in 79 adults diagnosed with alcohol dependence and SMI. RESULTS Thirty-nine percent (n = 31) of participants reported being homeless at baseline. Individuals who were homeless were more likely to drop out of CM (n = 10, 62.5%) than those who were housed (n = 4, 16.7%), χ2(1) = 8.86, P < .05. Homelessness was not associated with attrition in the noncontingent control group. Accounting for treatment group and prerandomization EtG levels, neither the effect of housing status nor the interaction of housing status and group were associated with EtG-assessed alcohol abstinence during treatment. CONCLUSIONS Individuals experiencing homelessness and co-occurring alcohol dependence and SMI receiving CM had higher rates of attrition, relative to those who were housed. Homelessness was not associated with differences in biologically assessed alcohol abstinence.

Abstract
BACKGROUND Excessive alcohol use among the homeless may contribute to their high rates of emergency department use. Survey-based studies have provided some information on the relation between alcohol and emergency department use among the homeless. METHODS This study used an intensive schedule of random breath collections and self-report assessments to examine the relation between emergency department utilization and alcohol use in homeless alcohol-dependent adults. Data were from homeless alcohol-dependent adults (N=116) who were participating in a therapeutic workplace that provided job-skills training every weekday for 26 weeks. Breath-sample collections and assessments of self-reported alcohol use were scheduled each week, an average of twice per week per participant, at random times between 9:00 A.M. and 5:00 P.M. Participants received $35 for each breath sample collected. Self-reports of emergency department use were assessed throughout the study. RESULTS Thirty-four percent of participants reported attending an emergency department and reported an average of 2.2 emergency department visits (range 1-10 visits). Alcohol intoxication was the most common reason for emergency department use. Participants who used the emergency department had significantly more alcohol-positive breath samples and more self-reported heavy alcohol use than participants who did not use the emergency department. CONCLUSIONS This study provided a rare intensive assessment of alcohol and emergency department use in homeless alcohol-dependent adults over an extended period. Emergency department use was high and was significantly related to indices of alcohol use.

Abstract
Use of illicit substances and nonmedical use of prescription medication worldwide has increased dramatically in the past several years. Approximately 10% of people who use illicit substances will develop a substance use disorder (SUD). Similar to other chronic health disorders, periods of remission and exacerbation commonly occur in SUDs. Due to stigma and difficulty with definition, terminology related to SUDs has changed and evolved. Terms referring to nonuse of substances such as sobriety and abstinence are likely best replaced with the term remission. Similarly, the use of the term relapse, in reference to a return to use after remission should be replaced with the term exacerbation. Research and professional organization consensus indicate that after a period of five years of remission or recovery, the risk of exacerbation is low in SUDs. Recovery is a term used to describe overall improvements in quality of life during remission. Recovery has been defined by organizations and studied in research. Factors that have been shown to improve the success of recovery are increased quality of life, improved self-efficacy, employment, and spirituality. It is important for nurses to improve their understanding of the terminology related to SUDs and to communicate with others using the terms that are the least stigmatizing. Nurses are in a prime position to assess recovery and to help patients and their families implement changes in order to improve the success of their recovery.

Abstract
BACKGROUND A clinical trial demonstrated that a therapeutic workplace could promote alcohol abstinence in homeless, alcohol-dependent adults. This secondary-data analysis examined rates of homelessness and their relation to the therapeutic workplace intervention and alcohol use during the trial. METHODS In the trial, homeless, alcohol-dependent adults could work in a therapeutic workplace for 6 months and were randomly assigned to Unpaid Training, Paid Training, or Contingent Paid Training groups. Unpaid Training participants were not paid for working. Paid Training participants were paid for working. Contingent Paid Training participants were paid for working if they provided alcohol-negative breath samples. Rates of homelessness during the study were calculated for each participant and the three groups were compared. Mixed-effects regression models were conducted to examine the relation between alcohol use (i.e., heavy drinking, drinks per drinking day, and days of alcohol abstinence) and homelessness. RESULTS Unpaid Training, Paid Training, and Contingent Paid Training participants did not differ in the percentage of study days spent homeless (31%, 28%, 17%; respectively; F(2,94)=1.732, p=0.183). However, participants with more heavy drinking days (b=0.350, p<0.001), more drinks per drinking day (b=0.267, p<0.001), and fewer days of alcohol abstinence (b=-0.285, p<0.001) spent more time homeless. CONCLUSIONS Reducing heavy drinking and alcohol use may help homeless, alcohol-dependent adults transition out of homelessness.

Abstract
Poverty is one of the most pervasive risk factors underlying poor health, but is rarely targeted to improve health. Research on the effects of anti-poverty interventions on health has been limited, at least in part because funding for that research has been limited. Anti-poverty programs have been applied on a large scale, frequently by governments, but without systematic development and cumulative programmatic experimental studies. Anti-poverty programs that produce lasting effects on poverty have not been developed. Before evaluating the effect of anti-poverty programs on health, programs must be developed that can reduce poverty consistently. Anti-poverty programs require systematic development and cumulative programmatic scientific evaluation. Research on the therapeutic workplace could provide a model for that research and an adaptation of the therapeutic workplace could serve as a foundation of a comprehensive anti-poverty program. Once effective anti-poverty programs are developed, future research could determine if those programs improve health in addition to increasing income. The potential personal, health and economic benefits of effective anti-poverty programs could be substantial, and could justify the major efforts and expenses that would be required to support systematic research to develop such programs.

Abstract
BACKGROUND The strong association between unemployment and drug addiction suggests that employment interventions are an important and needed focus of drug-addiction treatment. The increasing necessity of possessing basic academic skills to function in the workplace may require that some individuals receive educational training along with vocational training. OBJECTIVE This study investigated the academic skills of drug-addicted and chronically-unemployed adults (N = 559) who were enrolled in one of six studies conducted at the Center for Learning and Health in Baltimore, MD. METHODS Upon study enrollment, academic skills in math, spelling, and reading were examined using the Wide Range Achievement Test (WRAT-3 or WRAT-4) and educational history was examined using the Addiction Severity Index-Lite. RESULTS Although participants completed an average of 11 years of education, actual academic skill level was at or below the seventh grade level for 81% of participants in math, 61% in spelling, and 43% in reading, and most participants were classified as Low Average or below based on age group norms. Despite the fact that participants in this analysis were studied across several years and were from diverse populations, rates of high school completion and academic skill levels were remarkably similar. CONCLUSIONS Programs designed to improve the long-term employment status of drug-addicted individuals may benefit from the inclusion of basic adult education; future research on the topic is needed. Although establishing basic skills does not directly address chronic unemployment, it may help individuals obtain the jobs they desire and function effectively in those jobs.

Abstract
The field of behavioral economics has made important inroads into the understanding of substance use disorders through the concept of reinforcer pathology. Reinforcer pathology refers to the joint effects of (a) the persistently high valuation of a reinforcer, broadly defined to include tangible commodities and experiences, and/or (b) the excessive preference for the immediate acquisition or consumption of a commodity despite long-term negative outcomes. From this perspective, reinforcer pathology results from the recursive interactions of endogenous person-level variables and exogenous environment-level factors. The current review describes the basic principles of behavioral economics that are central to reinforcer pathology, the processes that engender reinforcer pathology, and the approaches and procedures that can repair reinforcement pathologies. The overall goal of this review is to present a new understanding of substance use disorders as viewed by recent advances in behavioral economics.

Abstract
BACKGROUND Research on contingency management to treat excessive alcohol use is limited due to feasibility issues with monitoring adherence. This study examined the effectiveness of using transdermal alcohol monitoring as a continuous measure of alcohol use to implement financial contingencies to reduce heavy drinking. METHODS Twenty-six male and female drinkers (from 21 to 39 years old) were recruited from the community. Participants were randomly assigned to one of the two treatment sequences. Sequence 1 received 4 weeks of no financial contingency (i.e., $0) drinking followed by 4 weeks each of $25 and then $50 contingency management; Sequence 2 received 4 weeks of $25 contingency management followed by 4 weeks each of no contingency (i.e., $0) and then $50 contingency management. During the $25 and $50 contingency management conditions, participants were paid each week when the Secure Continuous Remote Alcohol Monitor (SCRAM-II™) identified no heavy drinking days. RESULTS Participants in both contingency management conditions had fewer drinking episodes and reduced frequencies of heavy drinking compared to the $0 condition. Participants randomized to Sequence 2 (receiving $25 contingency before the $0 condition) exhibited less frequent drinking and less heavy drinking in the $0 condition compared to participants from Sequence 1. CONCLUSIONS Transdermal alcohol monitoring can be used to implement contingency management programs to reduce excessive alcohol consumption.

Abstract
Advancing the education of low-income adults could increase employment and income, but adult education programs have not successfully engaged low-income adults. Monetary reinforcement may be effective in promoting progress in adult education. This experiment evaluated the benefits of providing incentives for performance in a job-skills training program for low-income, unemployed adults. Participants worked on typing and keypad programs for 7 months. Participants randomly assigned to Group A (n = 23) earned hourly and productivity pay on the typing program (productivity pay), but earned only equalized hourly pay on the keypad program (hourly pay). Group B (n = 19) participants had the opposite contingencies. Participants worked more on, advanced further on, and preferred their productivity pay program. These results show that monetary incentives can increase performance in a job-skills training program, and indicate that payment in adult education programs should be delivered contingent on performance in the training program instead of simply on attendance.

Abstract
Employment-based reinforcement interventions have been used to promote abstinence from drugs among chronically unemployed injection drug users. The current study used an employment-based reinforcement intervention to promote opioid and cocaine abstinence among opioid and/or cocaine-dependent, HIV-positive participants who had recently completed a brief inpatient detoxification. Participants (n = 46) were randomly assigned to an abstinence and work group that was required to provide negative urine samples in order to enter the workplace and to earn incentives for work (n = 16), a work-only group that was permitted to enter the workplace and to earn incentives independent of drug use (n = 15), and a no-voucher control group that did not receive any incentives for working (n = 15) over a 26-week period. The primary outcome was urinalysis-confirmed opioid, cocaine, and combined opioid/cocaine abstinence. Participants were 78% male and 89% African American. Results showed no significant between-groups differences in urinalysis-verified drug abstinence or HIV risk behaviors during the 6-month intervention. The work-only group had significantly greater workplace attendance, and worked more minutes per day when compared to the no-voucher group. Several features of the study design, including the lack of an induction period, setting the threshold for entering the workplace too high by requiring immediate abstinence from several drugs, and increasing the risk of relapse by providing a brief detoxification that was not supported by any continued pharmacological intervention, likely prevented the workplace from becoming established as a reinforcer that could be used to promote drug abstinence. However, increases in workplace attendance have important implications for adult training programs.

Abstract
The current study examined whether monetary incentives could increase engagement and achievement in a job-skills training program for unemployed, homeless, alcohol-dependent adults. Participants (n=124) were randomized to a no-reinforcement group (n=39), during which access to the training program was provided but no incentives were given; a training reinforcement group (n=42), during which incentives were contingent on attendance and performance; or an abstinence and training reinforcement group (n=43), during which incentives were contingent on attendance and performance, but access was granted only if participants demonstrated abstinence from alcohol. abstinence and training reinforcement and training reinforcement participants advanced further in training and attended more hours than no-reinforcement participants. Monetary incentives were effective in promoting engagement and achievement in a job-skills training program for individuals who often do not take advantage of training programs.

Abstract
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.
