Abstract
Contingency management is an intervention for substance use disorders based on operant principles. The evidence base in support of contingency management is massive. It is effective in treating substance use disorder in general and opioid use disorder in particular. Dissemination has remained slow despite the urgency created by the opioid epidemic. Key barriers include a lack of expertise, time, and money. Implementing contingency management with smartphones eliminates the need for special training. It also solves logistical issues and requires little time on the part of clinicians. Thus, remaining barriers relate to cost. Federal anti-kickback regulations complicate solutions to the cost barrier. Other important regulatory challenges related to cost include the lack of billing codes and the difficulty of obtaining FDA approval for digital therapeutics. Even after the cost barrier is overcome, provider adoption is not guaranteed. Incentivizing providers for collaborative care may increase adoption and generate referrals. Recently proposed legislation and governmental policy statements provide optimism regarding the near-term large-scale adoption of contingency management in the treatment of opioid use disorder.

Drug Alcohol Depend 2021; 226:108907. [PMID: 34311206 PMCID: PMC8355098 DOI: 10.1016/j.drugalcdep.2021.108907] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/02/2021] [Revised: 05/26/2021] [Accepted: 05/30/2021] [Indexed: 11/29/2022]
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
Few studies have examined the relative effectiveness of reinforcing versus aversive consequences at changing behavior in real-world environments. Real-time sensing devices makes it easier to investigate such questions, offering the potential to improve both intervention outcomes and theory. This research aims to describe the development of a real-time, operant theory-based secondhand smoke (SHS) intervention and compare the efficacy of aversive versus aversive plus reinforcement contingency systems. Indoor air particle monitors were placed in the households of 253 smokers for approximately three months. Participants were assigned to a measurement-only control group (N = 129) or one of the following groups: 1.) aversive only (AO, N = 71), with aversive audio/visual consequences triggered by the detection of elevated air particle measurements, or 2.) aversive plus reinforcement (AP, N = 53), with reinforcing consequences contingent on the absence of SHS added to the AO intervention. Residualized change ANCOVA analysis compared particle concentrations over time and across groups. Post-hoc pairwise comparisons were also performed. After controlling for Baseline, Post-Baseline daily particle counts (F = 6.42, p = 0.002), % of time >15,000 counts (F = 7.72, p < 0.001), and daily particle events (F = 4.04, p = 0.02) significantly differed by study group. Nearly all control versus AO/AP pair-wise comparisons were statistically significant. No significant differences were found for AO versus AP groups. The aversive feedback system reduced SHS, but adding reinforcing consequences did not further improve outcomes. The complexity of real-world environments requires the nuances of these two contingency systems continue to be explored, with this study demonstrating that real-time sensing technology can serve as a platform for such research.

Abstract
BACKGROUND Opioid overdose remains a leading cause of death. Office-based buprenorphine could expand access to treatment to the many opioid users who are not in treatment and who are at risk for opioid overdose. However, many people in need of buprenorphine treatment do not enroll in treatment. This randomized pilot trial evaluated efficacy of a remotely delivered incentive intervention in promoting engagement in buprenorphine treatment in out-of-treatment adults with opioid use disorder. METHODS Participants (N = 41) were offered referrals to buprenorphine treatment and randomly assigned to Control or Incentive groups for 6 months. Incentive participants were offered incentives for enrolling in buprenorphine treatment, verified by providing documentation showing that they received a buprenorphine prescription, and providing videos taking daily buprenorphine doses. Participants used a smartphone application to record and submit a video of their buprenorphine prescription and daily buprenorphine administration. Incentive earnings were added remotely to reloadable credit cards. RESULTS Incentive participants were significantly more likely to enroll in treatment compared to control participants (71.4 % versus 30.0 % of participants; OR [95 % CI]: 6.24 [1.46-26.72], p = .014). Few participants in either group adhered to buprenorphine treatment, and the two groups continued to use opioids, including fentanyl at high and comparable rates. The two groups did not differ in the percentage of urine samples that were positive for buprenorphine, opiates, fentanyl, or methadone at monthly assessments conducted during the 6-month intervention. CONCLUSIONS Remotely delivered incentives can connect out-of-treatment adults with opioid use disorder to treatment, but additional supports are needed to promote buprenorphine adherence.

Abstract
Human behavior plays a central role in all domains of public health. Applied behavior analysis (ABA) research and practice can contribute to public health solutions that directly address human behavior. In this paper, we describe the field of public health, identify points of interaction between public health and ABA, summarize what ABA research has already contributed, and provide several recommendations for how ABA research and practice could continue to promote public health outcomes. A clearer focus on behavior and widespread adoption of research designs and interventions informed by the ABA literature could lead to better public health outcomes. Reciprocally, better integration of public health goals and strategies into ABA research, harnessing of technology, and more collaboration would help diversify and disseminate our applied science and could yield more effective and scalable interventions to prevent and treat public health problems.

Abstract
Scientific evidence in the field of psychiatry is mainly derived from group-based ("nomothetic") studies that yield group-aggregated results, while often the need is to answer questions that apply to individuals. Particularly in the presence of great inter-individual differences and temporal complexities, information at the individual-person level may be valuable for personalized treatment decisions, individual predictions and diagnostics. The single-subject study design can be used to make inferences about individual persons. Yet, the single-subject study is not often used in the field of psychiatry. We believe that this is because of a lack of awareness of its value rather than a lack of usefulness or feasibility. In the present paper, we aimed to resolve some common misconceptions and beliefs about single-subject studies by discussing some commonly heard "facts and fictions." We also discuss some situations in which the single-subject study is more or less appropriate, and the potential of combining single-subject and group-based study designs into one study. While not intending to plea for single-subject studies at the expense of group-based studies, we hope to increase awareness of the value of single-subject research by informing the reader about several aspects of this design, resolving misunderstanding, and providing references for further reading.

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

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

Abstract
Individuals with substance use disorders (SUDs) often face discrimination. A recent study found that people in the general population hold significantly more negative views toward persons with drug addiction than those with other mental illnesses (Barry et al. in Psychiatric Services, 65(10), 1269-1272, 2014). It is possible that these negative attitudes stem from the historical view of addiction as a moral shortcoming or lack of willpower. Behavior analysts' approach to behavior is guided by the underlying philosophy of behaviorism, which proposes that behavior is determined by genetic and environmental factors, as opposed to the free will of an individual. Because behavior analysts view behavior as determined and do not assign responsibility to an individual for his or her behavior, one would hypothesize that behavior analysts would not view individuals with SUDs more negatively than those with other mental disorders. This study surveyed 288 behavior analysts regarding their views on SUDs and mental disorders. Results showed that behavior analysts have significantly more negative attitudes toward people with SUDs than toward people with other mental disorders. Respondents reported a greater desire for social distance and greater acceptability of discrimination for people with SUDs than for people with mental disorders. They also reported less potential for recovery and lower support for policies to improve equity in insurance coverage and were less supportive of using government funding to improve treatment, housing, and job support for people with SUDs.

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
Contingency management is one of the most efficacious interventions to promote drug abstinence. Contingency management has traditionally been delivered in person so that clinicians could confirm drug abstinence and provide access to additional therapeutic services. Now, new technologies not only permit remote confirmation of abstinence, but also remote delivery of incentives. We discuss several technology-based tools to assess substance use, and new ways to deliver contingency management to promote tobacco, alcohol, and cannabis abstinence. These new tools have the potential to dramatically increase access while maintaining high levels of treatment fidelity. Technology-based methods also allow arranging group contingencies that harness online communities, and they permit targeting multiple health-risk behaviors with a combination of sensor-based technologies. Overall, there are unprecedented opportunities to link technology with contingency management to promote drug abstinence.

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
Behavioral momentum theory posits a paradoxical implication for behavioral interventions in clinical situations using Differential Reinforcement of Alternative Behavior (DRA): When alternative reinforcers are presented within the same context as the problem behavior, the added reinforcers may decrease the frequency of the behavior but also increase its persistence when the intervention ends. Providing alternative reinforcers in a setting that is distinctively different from that in which the target behavior occurs may avoid or reduce this increase in persistence. The present experiment compared behavioral persistence following standard DRA versus DRA in a different context that was available after refraining from target behavior (Differential Reinforcement of Other Behavior, DRO). We arranged a human laboratory model of treatment intervention using computer games and token reinforcement. Participants were five individuals with intellectual disabilities. Experimental phases included (a) an initial multiple-schedule baseline with token reinforcement for target behaviors A and B, (b) an intervention phase with alternative reinforcement using a conventional DRA procedure for A and a DRO-DRA procedure for B, and (c) an extinction phase with no interventions and no tokens. Response rates as proportion of baseline in the initial extinction phase were greater for A than for B for three of five participants. Four participants whose response rates remained relatively high during the extinction phase then received a second extinction-plus-distraction test with leisure items available. Response rates were greater for A than for B in three of four participants. The results indicate that DRO-DRA contingencies may contribute to reduced post-intervention persistence of problem behavior.

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
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
Research on a model Therapeutic Workplace has allowed for evaluation of the use of employment in the treatment of drug addiction. Under the Therapeutic Workplace intervention, adults with histories of drug addiction are hired and paid to work. To promote drug abstinence or adherence to addiction medications, participants are required to provide drug-free urine samples or take prescribed addiction medications, respectively, to gain access to the workplace and/or to maintain their maximum rate of pay. Research has shown that the Therapeutic Workplace intervention is effective in promoting and maintaining abstinence from heroin, cocaine and alcohol and in promoting adherence to naltrexone. Three models could be used to implement and maintain employment-based reinforcement in the treatment of drug addiction: A Social Business model, a Cooperative Employer model, and a Wage Supplement model. Under all models, participants initiate abstinence in a training and abstinence initiation phase (Phase 1). Under the Social Business model, Phase 1 graduates are hired as employees in a social business and required to maintain abstinence to maintain employment and/or maximum pay. Under the Cooperative Employer model, cooperating community employers hire graduates of Phase 1 and require them to maintain abstinence to maintain employment and/or maximum pay. Under the Wage Supplement Model, graduates of Phase 1 are offered abstinence-contingent wage supplements if they maintain competitive employment in a community job. Given the severity and persistence of the problem of drug addiction and the lack of treatments that can produce lasting effects, continued development of the Therapeutic Workplace is warranted.

Abstract
This secondary data analysis examined effects of an abstinence contingency on participation in a therapeutic workplace. Participants exposed to a pay reset after drug use did not differ in overall attendance from participants who were not exposed to a pay reset after drug use; however, they initially worked less after a pay reset than participants who did not receive a pay reset, and their attendance increased as their pay increased. Overall participation was not influenced by the abstinence contingency, but transient decreases in attendance occurred.

Abstract
OBJECTIVE Determine if employment-based reinforcement can increase methadone treatment engagement and drug abstinence in out-of-treatment injection drug users. METHOD This study was conducted from 2008 to 2012 in a therapeutic workplace in Baltimore, MD. After a 4-week induction, participants (N=98) could work and earn pay for 26 weeks and were randomly assigned to Work Reinforcement, Methadone & Work Reinforcement, and Abstinence, Methadone & Work Reinforcement conditions. Work Reinforcement participants had to work to earn pay. Methadone & Work Reinforcement and Abstinence, Methadone, & Work Reinforcement participants had to enroll in methadone treatment to work and maximize pay. Abstinence, Methadone, & Work Reinforcement participants had to provide opiate- and cocaine-negative urine samples to maximize pay. RESULTS Most participants (92%) enrolled in methadone treatment during induction. Drug abstinence increased as a graded function of the addition of the methadone and abstinence contingencies. Abstinence, Methadone & Work Reinforcement participants provided significantly more urine samples negative for opiates (75% versus 54%) and cocaine (57% versus 32%) than Work Reinforcement participants. Methadone & Work Reinforcement participants provided significantly more cocaine-negative samples than Work Reinforcement participants (55% versus 32%). CONCLUSION The therapeutic workplace can promote drug abstinence in out-of-treatment injection drug users. Clinical trial registration number: NCT01416584.

Abstract
This study evaluated the long-term effects of a therapeutic workplace social business on drug abstinence and employment. Pregnant and postpartum women (N = 40) enrolled in methadone treatment were randomly assigned to a therapeutic workplace or usual care control group. Therapeutic workplace participants could work weekdays in training and then as employees of a social business, but were required to provide drug-free urine samples to work and maintain maximum pay. Three-year outcomes were reported previously. This paper reports 4- to 8-year outcomes. During year 4 when the business was open, therapeutic workplace participants provided significantly more cocaine- and opiate-negative urine samples than controls; reported more days employed, higher employment income, and less money spent on drugs. During the 3 years after the business closed, therapeutic workplace participants only reported higher income than controls. A therapeutic workplace social business can maintain long-term abstinence and employment, but additional intervention may be required to sustain effects.

Abstract
We examined the use of employment-based abstinence reinforcement in out-of-treatment injection drug users, in this secondary analysis of a previously reported trial. Participants (N = 33) could work in the therapeutic workplace, a model employment-based program for drug addiction, for 30 weeks and could earn approximately $10 per hr. During a 4-week induction, participants only had to work to earn pay. After induction, access to the workplace was contingent on enrollment in methadone treatment. After participants met the methadone contingency for 3 weeks, they had to provide opiate-negative urine samples to maintain maximum pay. After participants met those contingencies for 3 weeks, they had to provide opiate- and cocaine-negative urine samples to maintain maximum pay. The percentage of drug-negative urine samples remained stable until the abstinence reinforcement contingency for each drug was applied. The percentage of opiate- and cocaine-negative urine samples increased abruptly and significantly after the opiate- and cocaine-abstinence contingencies, respectively, were applied. These results demonstrate that the sequential administration of employment-based abstinence reinforcement can increase opiate and cocaine abstinence among out-of-treatment injection drug users.

Abstract
Modifiable behavioral risk factors such as cigarette smoking, physical inactivity, and obesity contribute to over 40 % of premature deaths in the USA. Advances in digital and information technology are creating unprecedented opportunities for behavior analysts to assess and modify these risk factors. Technological advances include mobile devices, wearable sensors, biomarker detectors, and real-time access to therapeutic support via information technology. Integrating these advances with behavioral technology in the form of conceptually systematic principles and procedures could usher in a new generation of effective and scalable behavioral interventions targeting health behavior. In this selective review of the literature, we discuss how technological tools can assess and modify a range of antecedents and consequences of healthy and unhealthy behavior. We also describe practical, methodological, and conceptual advantages for behavior analysts that stem from the use of technology to assess and treat health behavior.

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
BACKGROUND Cocaine abuse continues to be a significant public health problem associated with morbidity and mortality. To date, no pharmacotherapeutic approach has proven effective for treating cocaine use disorders. Preclinical and clinical evidence suggests that noradrenergic activity may play a role in mediating some effects of cocaine and may be a rational target for treatment. METHODS This double blind, placebo-controlled randomized, parallel group, 12-week outpatient clinical trial enrolled cocaine dependent individuals seeking treatment to examine the potential efficacy of the selective norepinephrine reuptake inhibitor, atomoxetine (80 mg/day; p.o.; n = 25), compared to placebo (n = 25). Subjects were initially stratified on cocaine use (< 15 days or ≥ 15 days of the last 30), age and race using urn randomization. Attendance, medication adherence and study compliance were reinforced with contingency management, and weekly counseling was offered. An array of measures (vital signs, laboratory chemistries, cognitive and psychomotor tests, cocaine craving and urine samples for drug testing) was collected throughout the study and at follow-up. RESULTS Survival analysis revealed no differences in study retention between the two groups, with approximately 56% of subjects completing the 12-week study (Cox analysis χ(2) = .72; p = .40; Hazard Ratio 1.48 [95% CI 0.62-3.39]). GEE analysis of the proportion of urine samples positive for benzoylecgonine, a cocaine metabolite, revealed no differences between the atomoxetine and placebo groups (χ(2) = 0.2, p = .66; OR = 0.89 [95% CI 0.41-1.74]). Atomoxetine was generally well tolerated in this population. CONCLUSIONS These data provide no support for the utility of atomoxetine in the treatment of cocaine dependence.

Abstract
Drug abuse remains costly. Drug-related cues can evoke cue-reactivity and craving, contributing to relapse. The Pavlovian extinction-based cue-exposure therapy (CET) has not been very successful in treating drug abuse. A functional operant analysis of complex rituals involved in CET is outlined and reinterpreted as an operant heterogeneous chain maintained by observing responses, conditioned reinforcers, and discriminative stimuli. It is further noted that operant functions are not predicated on Pavlovian processes but can be influenced by them in contributing to relapse; several empirical studies from the animal and human literature highlight this view. Cue-reactivity evoked by Pavlovian processes is conceptualized as an operant establishing/motivating operation. CET may be more effective in incorporating an operant-based approach that takes into account the complexity of Pavlovian-operant interaction. Extinction of the operant chain coupled with the shaping of alternative behaviors is proposed as an integrated therapy. It is proposed that operant-based drug abuse treatments (contingency management, voucher programs, and the therapeutic work environment) might consider incorporating cue-reactivity, as establishing/motivating operations, to increase long-term success-a hybrid approach based on Pavlovian-operant interaction.

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.

Abstract
OBJECTIVE Poor medication adherence is a longstanding problem, and is especially pertinent for individuals with chronic conditions or diseases. Adherence to medications can improve patient outcomes and greatly reduce the cost of care. The purpose of the present review is to describe the literature on the use of incentives as applied to the problem of medication adherence. METHODS We conducted a systematic review of peer-reviewed empirical evaluations of incentives provided to patients contingent upon medication adherence. RESULTS This review suggests that incentive-based medication adherence interventions can be very effective, but there are few controlled studies. The studies on incentive-based medication adherence interventions most commonly feature patients taking medication for drug or alcohol dependence, HIV, or latent tuberculosis. Across studies that reported percent adherence comparisons, incentives increased adherence by a mean of 20 percentage points, but effects varied widely. Cross-study comparisons indicate a positive relationship between the value of the incentive and the impact of the intervention. Post-intervention evaluations were rare, but tended to find that adherence effects diminish after the interventions are discontinued. CONCLUSIONS Incentive-based medication adherence interventions are promising but understudied. A significant challenge for research in this area is the development of sustainable and cost-effective long-term interventions.

Abstract
The present analysis was conducted to validate an automated measurement system of noise violations by participants in the therapeutic workplace, which is a model workplace that offers paid employment and vocational training programs to illicit drug users. We collected data on dB levels via an electronic dB meter in a computer classroom with many different sound sources, and defined noise violations as sounds exceeding 55 dB. Human observers recorded whether staff or participants were responsible for violations, the types of events that resulted in violations, and whether these events were a result of participant behavior. Our analyses revealed that participants caused the majority of noise violations. These results suggest that the automated measurement system collects valid data on participant behavior that contributes to noise violations. Our results also suggest that these behaviors can in principle be modified to reduce the frequency of noise violations. Suggestions for replication in other settings and interventions designed to reduce behaviors leading to noise violations involving feedback and incentives are discussed.

Abstract
Improving employees' posture may decrease the risk of musculoskeletal disorders. The current paper is a systematic replication and extension of Sigurdsson and Austin (2008), who found that an intervention consisting of information, real-time feedback, and self-monitoring improved participant posture at mock workstations. In the current study, participants worked in an applied setting, and posture data were collected at participants' own workstations and a mock workstation. Intervention in the mock setting was associated with consistent improvement in safe posture at the mock workstation, but generalization to the actual workstation was limited.

Abstract
AIMS Naltrexone can be used to treat opioid dependence, but patients refuse to take it. Extended-release depot formulations may improve adherence, but long-term adherence rates to depot naltrexone are not known. This study determined long-term rates of adherence to depot naltrexone and whether employment-based reinforcement can improve adherence. DESIGN Participants who were inducted onto oral naltrexone were assigned randomly to contingency (n = 18) or prescription (n = 17) groups. Participants were offered six depot naltrexone injections and invited to work at the therapeutic workplace on week days for 26 weeks, where they earned stipends for participating in job skills training. Contingency participants were required to accept naltrexone injections to maintain workplace access and to maintain maximum pay. Prescription participants could work independently of whether they accepted injections. SETTING The therapeutic workplace, a model employment-based intervention for drug addiction and unemployment. PARTICIPANTS Opioid-dependent unemployed adults. MEASUREMENTS Depot naltrexone injections accepted and opiate-negative urine samples. FINDINGS Contingency participants accepted significantly more naltrexone injections than prescription participants (81% versus 42%), and were more likely to accept all injections (66% versus 35%). At monthly assessments (with missing urine samples imputed as positive), the groups provided similar percentages of samples negative for opiates (74% versus 62%) and for cocaine (56% versus 54%). Opiate-positive samples were more likely when samples were also positive for cocaine. CONCLUSIONS Employment-based reinforcement can maintain adherence to depot naltrexone. Future research should determine whether persistent cocaine use compromises naltrexone's effect on opiate use. Workplaces may be useful for promoting sustained adherence to depot naltrexone.

Abstract
AIMS To assess the efficacy of the Therapeutic Workplace, a substance abuse intervention that promotes abstinence while simultaneously addressing the issues of poverty and lack of job skills, in promoting abstinence from alcohol among homeless alcoholics. METHODS Participants (n = 124) were randomly assigned to conditions either requiring abstinence from alcohol to engage in paid job skills training (Contingent Paid Training group), offering paid job skills training with no abstinence contingencies (Paid Training group) or offering unpaid job skill training with no abstinence contingencies (Unpaid Training group). RESULTS Participants in the Contingent Paid Training group had significantly fewer positive (blood alcohol level ≥ 0.004 g/dl) breath samples than the Paid Training group in both randomly scheduled breath samples collected in the community and breath samples collected during monthly assessments. The breath sample results from the Unpaid Training group were similar in absolute terms to the Contingent Paid Training group, which may have been influenced by a lower breath sample collection rate in this group and fewer reported drinks per day consumed at intake. CONCLUSION Overall, the results support the utility of the Therapeutic Workplace intervention to promote abstinence from alcohol among homeless alcoholics, and support paid training as a way of increasing engagement in training programs.

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

Abstract
This study was a crosscultural replication of a study that investigated therapist adherence to behavioral interventions as a result of an intensive quality assurance system which was integrated into Multisystemic Therapy. Thirty-three therapists and eight supervisors participated in the study and were block randomized to either an Intensive Quality Assurance or a Workshop Only condition. Twenty-one of these therapists treated 41 cannabis-abusing adolescents and their families. Therapist adherence and youth drug screens were collected during a five-month baseline period prior to the workshop on contingency management and during 12 months post workshop. The results replicated the previous finding that therapist adherence to the cognitive-behavioral interventions, but not to contingency management, showed a strong positive difference in trend in favor of the intensive quality assurance condition. While the clinical impact of such quality assurance may be delayed and remains to be demonstrated, cannabis abstinence increased as a function of time in therapy, and was more likely with stronger therapy adherence to contingency management, but did not differ across quality assurance interventions.

Abstract
Token reinforcement procedures and concepts are reviewed and discussed in relation to general principles of behavior. The paper is divided into four main parts. Part I reviews and discusses previous research on token systems in relation to common behavioral functions--reinforcement, temporal organization, antecedent stimulus functions, and aversive control--emphasizing both the continuities with other contingencies and the distinctive features of token systems. Part II describes the role of token procedures in the symmetrical law of effect, the view that reinforcers (gains) and punishers (losses) can be measured in conceptually analogous terms. Part III considers the utility of token reinforcement procedures in cross-species analysis of behavior more generally, showing how token procedures can be used to bridge the methodological gulf separating research with humans from that with other animals. Part IV discusses the relevance of token systems to the field of behavioral economics. Token systems have the potential to significantly advance research and theory in behavioral economics, permitting both a more refined analysis of the costs and benefits underlying standard economic models, and a common currency more akin to human monetary systems. Some implications for applied research and for broader theoretical integration across disciplines will also be considered.

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

Abstract
Extensive evidence from the laboratory and the clinic suggests that drug addiction can be viewed as operant behavior and effectively treated through the application of principles of operant conditioning. Contingency management interventions that arrange for the direct reinforcement of drug abstinence or of other therapeutically important target behaviors (e.g., regular use of drug abuse treatment medications) are among the most studied type of operant treatments. Behavior analysts have contributed to the substantial and rapidly growing literature on operant treatments for drug addiction, but the publications of this work usually appear in medical, clinical psychology, or drug abuse journals. This special issue of the Journal of Applied Behavior Analysis represents an effort to bring this important work to the attention of the behavior-analytic community. The articles in this special issue illustrate both the enormous potential of contingency management interventions to address the serious and seemingly intractable problem of drug addiction as well as the real challenges involved in attempting to develop and disseminate treatments that will produce substantial and lasting changes in the lives of individuals plagued by the chronic problem of drug addiction.

Abstract
This study analyzed the viability of financing a voucher program for cocaine addicts in Spain through public and private donations. Of the 136 companies contacted, 52 (38%) provided donations. The difference between the benefits (15,670 Euro/ $20,371) and the costs (3734 Euro/ $4854) was 11,936 Euro/ $15,517. The type of reinforcer a company can offer, the size of the company, and the time elapsed before responding may be determining variables in a company's decision whether to collaborate.

Abstract
This study assessed whether attendance rates in a workplace predicted subsequent outcome of employment-based reinforcement of cocaine abstinence. Unemployed adults in Baltimore methadone programs who used cocaine (N=111) could work in a workplace for 4 hr every weekday and earn $10.00 per hour in vouchers for 26 weeks. During an induction period, participants provided urine samples but could work independent of their urinalysis results. After the induction period, participants had to provide urinalysis evidence of cocaine abstinence to work and maintain maximum pay. A multiple regression analysis showed that induction period attendance was independently associated with urinalysis evidence of cocaine abstinence under the employment-based abstinence reinforcement contingency. Induction period attendance may measure the reinforcing value of employment and could be used to guide the improvement of employment-based abstinence reinforcement.

Abstract
Contingency management (CM) is an effective treatment strategy for addressing many types of substance abuse disorders and associated problems. Nonetheless, CM protocols have not been widely embraced by community-based treatment providers. Exploration of the viability of CM outside of a research context remains largely an academic pursuit. In this paper, we outline several areas that may hinder the transfer of CM technology into community-based practice settings, review the literature that may address these barriers, and offer suggestions to researchers for overcoming them.

Abstract
This study assessed a 26-week voucher-based intervention to reinforce abstinence and participation in treatment-related activities among substance-abusing offenders court referred to outpatient treatment under drug diversion legislation (California's Substance Abuse and Crime Prevention Act). Standard treatment consisted of criminal justice supervision and an evidence-based model for treating stimulant abuse. Participants were randomly assigned to four groups, standard treatment (ST) only, ST plus vouchers for testing negative, ST plus vouchers for performing treatment plan activities, and ST plus vouchers for testing negative and/or performing treatment plan activities. Results indicate that voucher-based reinforcement of negative urines and of treatment plan tasks (using a flat reinforcement schedule) showed no statistically significant effects on measures of retention or drug use relative to the standard treatment protocol. It is likely that criminal justice contingencies had a stronger impact on participants' treatment retention and drug use than the relatively low-value vouchers awarded as part of the treatment protocol.

Abstract
In response to the growing number of drug offenders cycling in and out of the criminal justice system without treatment for underlying drug problems, the judicial system has increasingly adopted drug courts as a strategy to divert these offenders from incarceration to supervised drug treatment. Our aim was to determine if drug court treatment effectiveness could be improved using contingency management, in the form of twice-weekly vouchers, to reinforce abstinence and positive behaviors for 163 clients over 26 weeks. We found no significant differences in outcomes among the study groups, although the Treatment Plan Group that received reinforcement for positive behaviors showed a trend toward poorer performance. We suspect that the influence of the judge within the courtroom had a stronger impact on drug court clients' attitudes, drug use behaviors, and other outcomes than the relatively low-value vouchers awarded as part of the treatment protocol.

Abstract
High-magnitude and long-duration abstinence reinforcement can promote drug abstinence but can be difficult to finance. Employment may be a vehicle for arranging high-magnitude and long-duration abstinence reinforcement. This study determined if employment-based abstinence reinforcement could increase cocaine abstinence in adults who inject drugs and use cocaine during methadone treatment. Participants could work 4 hr every weekday in a workplace where they could earn about $10.00 per hour in vouchers; they were required to provide routine urine samples. Participants who attended the workplace and provided cocaine-positive urine samples during the initial 4 weeks were invited to work 26 weeks and were randomly assigned to an abstinence-and-work (n = 28) or work-only (n = 28) group. Abstinence-and-work participants had to provide urine samples showing cocaine abstinence to work and maintain maximum pay. Work-only participants could work independent of their urinalysis results. Abstinence-and-work participants provided more (p = .004; OR = 5.80, 95% CI = 2.03-16.56) cocaine-negative urine samples (29%) than did work-only participants (10%). Employment-based abstinence reinforcement can increase cocaine abstinence.

Abstract
Therapeutic workplace is a novel intervention that uses access to paid training and employment to reinforce drug abstinence within the context of standard methadone maintenance. We used the Drug Abuse Treatment Cost Analysis Program as a standard method of estimating the economic costs of this intervention. In a 1-year period, the therapeutic workplace served 122 methadone maintenance clients who had a median length of stay of 22 weeks. The workplace maintained a mean daily census of 48 clients. The combined cost of methadone maintenance and the therapeutic workplace was estimated at US$362 per week. This cost is less than that of other treatments that might be used to promote abstinence in individuals who continue to use drugs during methadone treatment. Given prior evidence of effectiveness, these cost data may be useful to policy makers, social service agencies, and researchers interested in using or further developing the therapeutic workplace intervention.

The current experiment compared the short-term effects of a transdermal nicotine patch to voucher-based reinforcement of smoking abstinence on cigarette smoking. Fourteen heavy smokers (7 men and 7 women) completed the four 5-day phases of the study: baseline, patch treatment, voucher treatment, and return to baseline. The order of the two treatment phases was counterbalanced across participants. In the patch treatment condition, participants wore a 14-mg transdermal nicotine patch every day. In the voucher treatment condition, participants received vouchers contingent on abstinence from smoking, defined as producing carbon monoxide (CO) readings of < or =4 parts per million. Participants e-mailed two video clips per day showing them breathing into a CO monitor and the resulting CO reading to clinic staff. In the voucher treatment, 24% of samples were negative, and 5% of samples were negative in the patch treatment. Results suggest that contingent vouchers were more effective than transdermal nicotine patches in promoting abstinence.

Abstract
The therapeutic workplace intervention is an employment-based drug user intervention that integrates abstinence reinforcement contingencies into an employment setting, intended for individuals manifesting chronic unemployment and drug addiction. Research on the therapeutic workplace intervention has provided a unique and rare opportunity to collect data and conduct fine-grained analyses of the training and work performance of participants. Results from a series of studies document that chronically unemployed drug users display behaviors that likely limit their success in conventional businesses. This article reviews a systematic line of research showing that targeted and intensive contingency management interventions and training programs have been effective in promoting consistent attendance and high rates of productivity and establishing job skills for employment.
