Abstract
BACKGROUND Substance use disorders are correlated with unemployment and poverty. However, few interventions aim to improve substance use, unemployment, and, distally, poverty. The Abstinence-Contingent Wage Supplement (ACWS) randomized controlled trial combined a therapeutic workplace with abstinence-contingent wage supplements to address substance use and unemployment. The ACWS study found that abstinence-contingent wage supplements increased the percentage of participants who had negative drug tests, who were employed, and who were above the poverty line during the intervention period. This study presents the cost of ACWS and calculates the cost-effectiveness of ACWS compared with usual care. METHODS To calculate the cost and cost-effectiveness of ACWS, we used activity-based costing methods to cost the intervention and calculated the costs from the provider and healthcare sector perspective. We calculated incremental cost-effectiveness ratios and cost-effectiveness acceptability curves for negative drug tests and employment. RESULTS ACWS cost $11,310 per participant over the 12-month intervention period. Total intervention and healthcare costs per participant over the intervention period were $20,625 for usual care and $30,686 for ACWS. At the end of the intervention period an additional participant with a negative drug test cost $1437 while an additional participant employed cost $915. CONCLUSIONS ACWS increases drug abstinence and employment and may be cost-effective at the end of the 12-month intervention period if decision makers are willing to pay the incremental cost associated with the intervention.

Pickard H. Is addiction a brain disease? A plea for agnosticism and heterogeneity. Psychopharmacology (Berl) 2022; 239:993-1007. [PMID: 34825924 DOI: 10.1007/s00213-021-06013-4] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2021] [Accepted: 10/19/2021] [Indexed: 11/29/2022]
Abstract
RATIONALE Although increasingly subject to criticism, the brain disease model of addiction (BDMA) remains dominant within addiction science. Yet few advocates or critics of the BDMA have provided an account of what a brain disease is. The aim of this review is to conceptually clarify what it would mean for the BDMA to be true, rather than to argue decisively for or against it. OBJECTIVES Conceptual clarification of the BDMA requires consideration of possible models of disease and their relationship to the BDMA. A barrier to such consideration is belief that the BDMA is necessary to combatting addiction stigma. To address this barrier, I begin with discussion of what we know about the effects of the brain disease label on addiction stigma, and why labelling effects should have no bearing on the validity of the BDMA. I then distinguish strong, minimal, network, and mismatch models of disease, and I argue that the BDMA aligns with a strong disease model. This means that underlying brain pathology is hypothesized to be the cause of the personal-level observable signs and experienced symptoms characteristic of addiction. Evaluation of the BDMA therefore requires analysis of the concepts of brain dysfunction and causation, and their application to addiction science. RESULTS Brain dysfunction cannot be analyzed merely as brain changes or brain differences; nor can it be inferred merely from the presence of personal-level signs and symptoms. It is necessary to have an account of normal brain function by which to measure it. The theoretical and empirical challenges to developing such an account are not insurmountable, but they are substantial. Although there exist competing analyses of causation, there is a relatively standard method used to establish it within experimental science: intervention. Using this method, the causal significance of brain states, such as, e.g., extensive gray matter loss and/or neuroadapations in the mesocorticolimbic dopamine system, is not yet fully demonstrated. Further studies are necessary to determine their effect compared with other possible variables, such as, e.g., alternative reinforcers. CONCLUSIONS Conceptual clarification and preliminary empirical assessment of the BDMA recommends agnosticism about its validity and an openness to heterogeneity; in some cases addiction may be a brain disease, in others not. Either way, addiction stigma can be combatted by fighting moralism about drugs and moralistic drug policies directly, as opposed to resting hopes on the brain disease label.

Being at work improves stress, craving, and mood for people with opioid use disorder: Ecological momentary assessment during a randomized trial of experimental employment in a contingency-management-based therapeutic workplace. Behav Res Ther 2022; 152:104071.

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.

Treatments, Perceived Stigma, and Employment Outcomes among Substance Abusers in China. Healthcare (Basel) 2022; 10:healthcare10010130.

Abstract
Employment is a vital component of a substance abuser's recovery, but little is known about how stigma affects employment for substance abusers receiving treatment. The current study investigates the effects of stigma and treatment on employment in the Chinese context. Using a sample of substance abusers (N = 3.978), multiple logistics regressions with moderation effects were employed. The findings show that treatments positively reduce confirmative experiences of anticipated stigma, and promote employment only when respondents do not perceive stigma. The findings highlight the impact of perceived stigma on limiting substance abusers' chances of being employed, implying that eliminating stigma is the foundation for recovery. Possible strategies that can be explored for reducing stigma are discussed.

DRUG AND ALCOHOL DEPENDENCE REPORTS 2021; 1:100011. [PMID: 36843907 PMCID: PMC9948824 DOI: 10.1016/j.dadr.2021.100011] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/16/2021] [Revised: 11/25/2021] [Accepted: 12/01/2021] [Indexed: 11/25/2022]
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
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
The landscape of addiction is dominated by two rival models: a moral model and a model that characterizes addiction as a neurobiological disease of compulsion. Against both, I offer a scientifically and clinically informed alternative. Addiction is a highly heterogenous condition that is ill-characterized as involving compulsive use. On the whole, drug consumption in addiction remains goal directed: people take drugs because drugs have tremendous value. This view has potential implications for the claim that addiction is, in all cases, a brain disease. But more importantly, it has implications for clinical and policy interventions. To help someone overcome addiction, you need to understand and address why they persist in using drugs despite negative consequences. If they are not compelled, then the explanation must advert to the value of drugs for them as an individual. What blocks us from acknowledging this reality is not science but fear: that it will ignite moralism about drugs and condemnation of drug users. The solution is not to cleave to the concept of compulsion but to fight moralism directly.

Abstract
Although vivid memories of drug experiences are prevalent within clinical contexts and addiction folklore ("chasing the first high"), little is known about the relevance of cognitive processes governing memory retrieval to substance use disorder. Drawing on recent work that identifies episodic memory's influence on decisions for reward, we propose a framework in which drug choices are biased by selective sampling of individual memories during two phases of addiction: (i) downward spiral into persistent use and (ii) relapse. Consideration of how memory retrieval influences the addiction process suggests novel treatment strategies. Rather than try to break learned associations between drug cues and drug rewards, treatment should aim to strengthen existing and/or create new associations between drug cues and drug-inconsistent rewards.

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
Unemployment, homelessness, and substance use are interrelated. The present study took place as part of a clinical trial aimed to promote employment and abstinence from alcohol in unemployed, homeless adults with alcohol use disorders. Participants earned abstinence-contingent financial incentives for completing employment-seeking activities and hourly stipends for working with an employment specialist. In the initial condition, participants were paid all earnings on Bi-Monthly intervals. Despite the availability of incentives for completing employment-seeking activities, participants completed activities at low rates. A multiple-baseline across participants was used to evaluate the effect of providing pay every day for completing employment-seeking activities. Daily pay increased rates of completing activities for all three participants. Results suggest that reinforcer immediacy can be an important parameter in the control of employment-seeking activities.

The Association between Living Status Transitions, Behavior Changes and Family Relationship Improvement among Methadone Maintenance Treatment Participants in Guangdong, China.

Abstract
The quality of family relationships is important for individual and family well-being. Improving family relationships is also an important goal in methadone maintenance treatment (MMT). Little is known about factors associated with the improvement of family relationships among MMT clients. This study aimed to identify factors associated with family relationship improvement in MMT. We retrospectively analyzed existing data from 2006 to 2014 at 15 MMT clinics in Guangdong, China, including 2171 subjects with 4691 follow-ups. Generalized estimating equations were used to investigate the association between living status transitions, behavior changes and family relationship improvement, with covariates controlled for. Family relationship improvement was found in 23.1% of all follow-up intervals. Participants who began living with family, living on a regular wage, and gained employment were more likely to have improved family relationships. The quality of family relationships also improved among participants who ceased contact with drug-addicted fellows, ceased drug use, and those who were sexually active. These results suggest that improvement in living status, positive changes in drug use, and sexual activity are associated with family relationship improvement and corresponding interventions may be developed to facilitate clients’ recovery.

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
BACKGROUND The purpose of this study was to assess what is associated with health service satisfaction among adults with a substance use disorder receiving services provided within different municipalities in Norway. An additional aim was to examine demographic and municipality characteristics, mental health, and types of substance use associated with health service satisfaction. METHOD A cross-sectional partial explorative study was executed in 2017 among 491 service users with substance use disorders from 20 randomly selected municipalities. The sample consisted of 70% males. The sample majority were single and unemployed, and their main sources of healthcare were the general practitioner (78%), The Norwegian Labor and Welfare Administration (72%), and addiction counsellors (62%). RESULTS Overall satisfaction was negatively associated with age, size of municipality, Global Severity Index (GSI) and illicit substance use during the last 12 months. Satisfaction with practical help, such as housing, economy, work and education, was negatively associated with GSI and positively associated with onset of first alcohol intoxication. Satisfaction with personnel was positively associated with onset of first alcohol intoxication and negatively associated with municipality size, GSI and illicit use the last 12 months. The results showed that more than half of the respondents (54%) to a large or great extent were satisfied with the overall services provided. The services they were less satisfied with were related to housing, economy, getting started with exercise and establishing a social network. CONCLUSION The results show areas associated with satisfaction and domains where the municipalities can improve their services to meet the users' needs and increase service satisfaction.

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 link between illicit drug use and impaired employee performance in the workplace has been assumed, but the relation has not been demonstrated clearly in research. This study was an evaluation of the relations between cocaine and opiate use, attendance, and performance in a job skills training program in a population with high rates of drug use. METHODS Out-of-treatment injection drug users (N = 42) attended a model therapeutic workplace where they could earn a maximum pay of around $10 per hour, 4 h every weekday, for 30 weeks. At the workplace, participants could complete practice trials on computer-based typing and keypad training programs. Participants were asked to provide urine samples thrice weekly, which were tested for opiates and cocaine. RESULTS Participants worked for more hours on a program that resulted in a flat hourly wage when their urine was negative for opiates and cocaine than when their urine was opiate and cocaine positive. Attendance was positively associated with opiate-negative samples during the study. When participants attended the workplace, however, their performance was not related to drug use. Participants completed the same number of practice trials, performed at the same accuracy, and typed at the same speed when they were positive and negative for cocaine and opiates. CONCLUSIONS Contrary to common expectations, this study failed to show that the use of opiates or cocaine affected in-training performance, even though opiate and cocaine use predicted reduced attendance under some circumstances.

Abstract
Background The development and evaluation of digital interventions aimed at preventing or treating substance use–related problems and disorders is a rapidly growing field. Previous reviews of such interventions reveal a large and complex picture with regard to targeted users, use, and efficacy. Objective The objective of this review was to investigate the feasibility and effects of interventions developed specifically for digital platforms. These interventions are focused on supporting people in recovery from substance use disorders by helping them achieve their substance use goals and develop a more satisfying life situation. Methods The review is based on a systematic search in MEDLINE, Embase, PsycInfo, and Cochrane Library databases. Of the 1149 identified articles, 722 were excluded as obviously not relevant. Of the remaining articles, 21 were found to be previous reviews, 269 were on interventions aimed at reducing hazardous alcohol or cannabis use, and 94 were on digitized versions of standard treatment methods. The remaining 43 articles were all read in full and systematically scored by both authors. Results The 43 articles cover 28 unique interventions, of which 33 have been published after 2013. The interventions are aimed at different target groups (defined by age, substance, or comorbidity). Based on the number of features or modules, the interventions can be categorized as simple or complex. Fourteen of the 18 simple interventions and 9 of the 10 complex interventions have been studied with quantitative controlled methodologies. Thirteen of the 18 simple interventions are integrated in other treatment or support systems, mainly delivered as mobile phone apps, while 6 of the 10 complex interventions are designed as stand-alone interventions, most often delivered on a platform combining desktop/Web and mobile phone technologies. The interventions were generally easy to implement, but in most cases the implementation of the complex interventions was found to be dependent on sustained organizational support. Between 70% and 90% of the participants found the interventions to be useful and easy to use. The rates of sustained use were also generally high, except for simple interventions with an open internet-based recruitment and some information and education modules of the complex interventions. Across all interventions, slightly more than half (55%) of the studies with control groups generated positive findings on 1 or more substance use outcomes, with 57% of the interventions also found to be efficacious in 1 or more studies. In the positive studies, effects were typically in the small to moderate range, with a few studies yielding larger effects. Largely due to the inclusion of stronger control conditions, studies of simple interventions were less likely to produce positive effects. Conclusions The digital interventions included in this review are in general feasible but are not consistently effective in helping people in recovery from substance use disorder reduce their substance use or achieving other recovery goals.

Abstract
This study developed a computer-based program to teach HIV prevention behaviors and raise awareness of pre-exposure prophylaxis (PrEP) among individuals at risk for HIV. The program was divided into modules containing educational material and multiple-choice questions. Participants received immediate feedback for responses and incentives for correct responses to multiple-choice questions. Participants trained on each module until they met speed and accuracy criteria. The modules were divided into: Course 1 (HIV), Course 2 (PrEP), and Course 3 (HIV risk behaviors). Tests of content from all three courses were delivered before and after participants completed each course. Test scores on the content delivered in the courses improved only after participants completed training on each course. HIV and PrEP knowledge was initially low and increased following completion of each part of the program. Computer-based training offers a convenient and effective approach to promoting HIV prevention knowledge, including use of PrEP.

Abstract
AIMS To review systematically the published literature on extended-release naltrexone (XR-NTX, Vivitrol® ), marketed as a once-per-month injection product to treat opioid use disorder. We addressed the following questions: (1) how successful is induction on XR-NTX; (2) what are adherence rates to XR-NTX; and (3) does XR-NTX decrease opioid use? Factors associated with these outcomes as well as overdose rates were examined. METHODS We searched PubMed and used Google Scholar for forward citation searches of peer-reviewed papers from January 2006 to June 2017. Studies that included individuals seeking treatment for opioid use disorder who were offered XR-NTX were included. RESULTS We identified and included 34 studies. Pooled estimates showed that XR-NTX induction success was lower in studies that included individuals that required opioid detoxification [62.6%, 95% confidence interval (CI) = 54.5-70.0%] compared with studies that included individuals already detoxified from opioids (85.0%, 95% CI = 78.0-90.1%); 44.2% (95% CI = 33.1-55.9%) of individuals took all scheduled injections of XR-NTX, which were usually six or fewer. Adherence was higher in prospective investigational studies (i.e. studies conducted in a research context according to a study protocol) compared to retrospective studies of medical records taken from routine care (6-month rates: 46.7%, 95% CI = 34.5-59.2% versus 10.5%, 95% CI = 4.6-22.4%, respectively). Compared with referral to treatment, XR-NTX reduced opioid use in adults under criminal justice supervision and when administered to inmates before release. XR-NTX reduced opioid use compared with placebo in Russian adults, but this effect was confounded by differential retention between study groups. XR-NTX showed similar efficacy to buprenorphine when randomization occurred after detoxification, but was inferior to buprenorphine when randomization occurred prior to detoxification. CONCLUSIONS Many individuals intending to start extended-release naltrexone (XR-NTX) do not and most who do start XR-NTX discontinue treatment prematurely, two factors that limit its clinical utility significantly. XR-NTX appears to decrease opioid use but there are few experimental demonstrations of this effect.

Abstract
This qualitative study of over 800 participants focused on the employment experiences of consumers of substance abuse treatment programs to provide a better understanding of what employment services are offered and what needs treatment agencies have in the area of employment services, examining barriers and facilitators from both the consumer and provider perspectives. Data were collected via a mixed research methodology of focus groups and surveys from July 2015 through June 2016 in a large Midwestern U.S. state. Employment is a challenge for persons with substance use disorders. Only a quarter of this study's large sample of substance abuse treatment consumers reported being cur-rently employed; and of those consumers who reported no current employment, greater than half reported that their current unemployment was due to their substance use. Persons receiving substance abuse treatment face many challenges in obtaining and maintaining employment. Treatment providers identified several barriers to implementation of employment services. They named an array of resources as needed, including increased funding for supportive employment programs and staff appropriate to the delivery of employment services. Some providers believed employment services to fall outside of their scope of practice. Data generated through this study may inform policy to invest resources in employment services within substance abuse treatment settings.

Abstract
BACKGROUND Research has led to improvements in the effectiveness of interventions for substance use disorders (SUD), but for the most part progress has been modest, particularly with regard to longer-term outcomes. Moreover, most individuals with SUD do not seek out treatment. ARGUMENT/ANALYSIS This paper presents two recommendations on how to improve treatment engagement and long-term outcomes for those with SUD. First, treatments should go beyond a focus on reducing or eliminating substance use to target greater access to and more time spent in experiences that will be enjoyable or otherwise rewarding to clients. Secondly, there must be sufficient incentives in the environment to justify the effort needed to sustain long-term abstinence for individuals who often have limited access to such incentives. CONCLUSIONS To increase rates of long-term recovery from substance misuse, treatments should link clients to reinforcers that will make continued abstinence more appealing. This work needs to extend beyond interventions focused on the individual or family to include the local community and national policy in an effort to incentivize longer-term recoveries more strongly.

Abstract
AIM To test whether an incentive-based intervention that increased adherence to naltrexone also increased opiate abstinence. DESIGN Post-hoc combined analysis of three earlier randomized controlled trials that showed individually that incentives for adherence to oral and to extended-release injection naltrexone dosing schedules increased naltrexone adherence, but not opiate abstinence. SETTING Out-patient therapeutic work-place in Baltimore, MD, USA. PARTICIPANTS One hundred and forty unemployed heroin-dependent adults participating from 2006 to 2010. INTERVENTIONS Participants were hired in a model work-place for 26 weeks and randomized to a contingency (n = 72) or prescription (n = 68) group. Both groups were offered naltrexone. Contingency participants were required to take scheduled doses of naltrexone in order to work and earn wages. Prescription participants could earn wages independent of naltrexone adherence. MEASURES Thrice-weekly and monthly urine samples tested for opiates and cocaine and measures of naltrexone adherence (percentage of monthly urine samples positive for naltrexone or percentage of scheduled injections received). All analyses included pre-randomization attendance, opiate use and cocaine use as covariates. Additional analyses controlled for cocaine use and naltrexone adherence during the intervention. FINDINGS Contingency participants had more opiate abstinence than prescription participants (68.1 versus 52.9% opiate-negative thrice-weekly urine samples, respectively; and 71.9 versus 61.7% opiate-negative monthly urine samples, respectively) based on initial analyses [thrice-weekly samples, odds ratio (OR) = 3.3, 95% confidence interval (CI) = 1.7-6.5, P < 0.01; monthly samples, OR = 2.6, 95% CI = 1.0-7.1, P = 0.06] and on analyses that controlled for cocaine use (thrice-weekly samples, OR = 3.9, 95% CI = 3.3-4.5, P < 0.01; monthly samples, OR = 3.4, 95% CI = 1.1-11.1, P = 0.04), which was high and associated with opiate use. The difference in opiate abstinence rates between contingency and prescription participants was reduced when controlling for naltrexone adherence (monthly samples, OR = 1.1, 95% CI = 0.7-1.7, P = 0.84). CONCLUSIONS Incentives for naltrexone adherence increase opiate abstinence in heroin-dependent adults, an effect that appears to be due to increased naltrexone adherence produced by the incentives.

Abstract
Drug addiction is a chronic, relapsing health problem that is associated with the degree to which individuals choose small, immediate monetary outcomes over larger, delayed outcomes. This study was a secondary analysis exploring the relation between financial choices and drug use in opioid-dependent adults in a therapeutic workplace intervention. Sixty-seven participants were randomly assigned to a condition in which access to paid job training was contingent upon naltrexone adherence (N = 35) or independent of naltrexone adherence (N = 32). Participants could earn approximately $10 per hour for 4 hours every weekday and could exchange earnings for gift cards or bill payments each weekday. Urine was collected and tested for opiates and cocaine thrice weekly. Participants' earning, spending, and drug use were not related to measures of delay discounting obtained prior to the intervention. When financial choices were categorized based on drug use during the intervention, however, those with less frequent drug use or frequent use of one drug spent a smaller proportion of their daily earnings and maintained a higher daily balance than those who frequently tested positive for both drugs (i.e., opiates and cocaine). Several patterns described the relation between cumulative earning and spending including no saving, periods of saving, and sustained saving. One destructive effect of drug use may be that it creates a perpetual zero-balance situation in the lives of users, which in turn prevents them from gaining materials that could help to break the cycle of addiction.

Abstract
BACKGROUND AND AIM Extended-release naltrexone (XR-NTX) blocks the effects of opioids for 4weeks; however, starting treatment can be challenging because it requires 7 to 10days of abstinence from all opioids. In the present study we identified patient and treatment characteristics that were associated with successful induction onto XR-NTX. METHODS 144 unemployed heroin-dependent adults who had recently undergone opioid detoxification completed self-report measures and behavioral tasks before starting an outpatient XR-NTX induction procedure. Employment-based reinforcement was used to promote opioid abstinence and adherence to oral naltrexone during the induction. Participants were invited to attend a therapeutic workplace where they earned wages for completing jobs skills training. Participants who had used opioids recently were initially invited to attend the workplace for a 7-day washout period. Then those participants were required to provide opioid-negative urine samples and then take scheduled doses of oral naltrexone to work and earn wages. Participants who had not recently used opioids could begin oral naltrexone immediately. After stabilization on oral naltrexone, participants were eligible to receive XR-NTX and were randomized into one of four treatment groups, two of which were offered XR-NTX. Binary and multiple logistic regressions were used to identify characteristics at intake that were associated with successfully completing the XR-NTX induction. RESULTS 58.3% of participants completed the XR-NTX induction. Those who could begin oral naltrexone immediately were more likely to complete the induction than those who could not (79.5% vs. 25.0%). Of 15 characteristics, 2 were independently associated with XR-NTX induction success: legal status and recent opioid detoxification type. Participants who were not on parole or probation (vs. on parole or probation) were more likely to complete the induction (OR [95% CI]=2.5 [1.1-5.7], p=0.034), as were those who had come from a longer-term detoxification program (≥21days) (vs. a shorter-term [<21days]) (OR [95% CI]=7.0 [3.0-16.6], p<0.001). CONCLUSIONS Our analyses suggest that individuals recently leaving longer-term opioid detoxification programs are more likely to complete XR-NTX induction. Individuals on parole or probation are less likely to complete XR-NTX induction and may need additional supports or modifications to induction procedures to be successful.

Abstract
Poverty is a pervasive risk factor underlying poor health. Many interventions that have sought to reduce health disparities associated with poverty have focused on improving health-related behaviors of low-income adults. Poverty itself could be targeted to improve health, but this approach would require programs that can consistently move poor individuals out of poverty. Governments and other organizations in the United States have tested a diverse range of antipoverty programs, generally on a large scale and in conjunction with welfare reform initiatives. This paper reviews antipoverty programs that used financial incentives to promote education and employment among welfare recipients and other low-income adults. The incentive-based, antipoverty programs had small or no effects on the target behaviors; they were implemented on large scales from the outset, without systematic development and evaluation of their components; and they did not apply principles of operant conditioning that have been shown to determine the effectiveness of incentive or reinforcement interventions. By applying basic principles of operant conditioning, behavior analysts could help address poverty and improve health through development of effective antipoverty programs. This paper describes a potential framework for a behavior-analytic antipoverty program, with the goal of illustrating that behavior analysts could be uniquely suited to make substantial contributions to the war on poverty.

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.

The effects of the therapeutic workplace and heavy alcohol use on homelessness among homeless alcohol-dependent adults. Drug Alcohol Depend 2016; 168:135-139. [PMID: 27648854 DOI: 10.1016/j.drugalcdep.2016.09.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/13/2016] [Revised: 09/08/2016] [Accepted: 09/09/2016] [Indexed: 11/20/2022]
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.
