Abstract
Human laboratory models in substance use disorder provide a key intermediary step between highly controlled and mechanistically informative non-human preclinical methods and clinical trials conducted in human populations. Much like preclinical models, the variety of human laboratory methods provide insights into specific features of substance use disorder rather than modelling the diverse causes and consequences simultaneously in a single model. This narrative review provides a discussion of popular models of reward used in human laboratory research on substance use disorder with a focus on the specific contributions that each model has towards informing clinical outcomes (forward translation) and analogs within preclinical models (backward translation). Four core areas of human laboratory research are discussed: drug self-administration, subjective effects, behavioral economics, and cognitive and executive function. Discussion of common measures and models used, the features of substance use disorder that these methods are purported to evaluate, unique issues for measure validity and application, and translational links to preclinical models and special considerations for studies wishing to evaluate homology across species is provided.

Abstract
Background Corrections-involved adults with a history of opioid use disorder are at elevated risk of opioid overdose following release from correctional settings. Increased opioid prescribing restrictions and monitoring during a time when heroin is becoming cheaper and ubiquitous means that adults who misused prescription opioids prior to incarceration may be reentering communities at greater risk for heroin exposure and use. Objectives Determine risk factors of post-release heroin use among a sample of adults who participated in corrections-based drug treatment in Kentucky released between 2012 and 2017. Methods Survey data obtained as part of an ongoing evaluation of corrections-based drug treatment were examined. Results The final sample (N = 1,563) was majority male (80.9%). Nearly 11.0% reported past-year heroin use following their release. Depressive symptoms, polydrug use, and urban proximity were more common among participants reporting post-release heroin use. Heroin use 30 days prior to incarceration was associated with a 432.1% increase in odds of heroin use subsequent to incarceration. Post-release suicidal ideation increased odds of heroin use by 154.2%, whereas reporting satisfaction from social interactions decreased odds of use by nearly 60%. Post-release use of cocaine and diverted buprenorphine were associated with increased likelihood of heroin use during this time period, increasing odds by 469.1% and 265.9%, respectively. Residing in Central Appalachia subsequent to incarceration was associated with decreased likelihood of use. Conclusions In this sample, post-release heroin use was associated with concerning features, such as polydrug use, lack of social satisfaction, and suicidal ideation. These features can serve as clear targets for clinical intervention.

Abstract
BACKGROUND Illicit, medically unsupervised use of buprenorphine (i.e., "diverted use") among vulnerable and underserved populations, such as corrections-involved adults, remains underexplored. METHODS Survey data (2016-2017) collected as part of a clinical assessment of incarcerated adults entering corrections-based substance use treatment in Kentucky were analyzed. For years examined, 12,915 completed the survey. Removing cases for participants who did not reside in Kentucky for >6 months during the one-year pre-incarceration period (n = 908) resulted in a final sample size of 12,007. RESULTS Over a quarter of the sample reported past-year diverted buprenorphine use prior to incarceration and 21.8 % reported use during the 30-days prior to incarceration, using 6.5 months and 14.3 days on average, respectively. A greater proportion of participants who reported diverted buprenorphine use had previously been engaged with some substance use treatment (77.0 %) and reported greater perceived need for treatment (79.4 %) compared to those who did not report use. Use was more likely among participants who were younger, white, male, and who reported rural or Appalachian residence. Diverted buprenorphine users also evidenced extensive polydrug use and presented with greater substance use disorder severity. Non-medical prescription opioid, heroin, and diverted methadone use were associated with increased odds of diverted buprenorphine use while kratom was not. Diverted methadone use was associated with a 252.9 % increased likelihood of diverted buprenorphine use. CONCLUSIONS Diverted buprenorphine use among participants in this sample was associated with concerning high-risk behaviors and may indicate barriers to accessing opioid agonist therapies for corrections-involved Kentucky residents, particularly those in rural Appalachia.

J Psychoactive Drugs 2019; 51:311-322.

Abstract
In Asia, Mitragyna speciosa (e.g., "kratom") has been used to mitigate alcohol and drug dependence. Some preliminary findings suggest kratom's potential use as an informal harm-reduction method in the United States, such as an opioid substitute or as a means of lessening opioid withdrawal symptoms. To determine correlates of past-year kratom use among a sample of polysubstance users enrolled in residential recovery programs in Kentucky, an anonymous survey was completed by clients in April 2017. Logistic regression was used to identify significant associations with past-year kratom use. Of the final sample (N = 478), 10.4% reported past-year kratom use. Past-year heroin use, but not past-year prescription opioid (e.g., oxycodone, hydrocodone) use, was significantly associated with kratom use, such that individuals who reported past-year heroin use were 2.5 times more likely to also report past-year kratom use. Non-prescribed buprenorphine (i.e., Suboxone) use partially mediated the relationship between past-year heroin and kratom use by explaining 36% of the association between the two drugs. Though amphetamines were highly preferred, past-year use was negatively correlated with past-year kratom use. Rates of past-year kratom use were lower than rates of alcohol and illicit drug use. Kratom was not preferred over heroin or prescription opioids.

Abstract
OBJECTIVE To examine whether galantamine, a cognitive-enhancing medication that is both acetylcholinesterase inhibitor and agonist at nicotinic acetylcholine receptors, is effective at improving cocaine use outcomes and cognitive functioning, alone and in combination with computerized cognitive behavioral therapy (CBT). METHOD A 12-week, randomized 2 × 2, factorial trial was conducted to evaluate galantamine versus placebo (double-blind) and computerized CBT plus standard methadone treatment versus standard methadone treatment alone in a community-based methadone maintenance program (September 2009-April 2015). One hundred twenty individuals diagnosed with DSM-IV cocaine use disorder were randomly assigned to the following conditions: (1) galantamine (8 mg/d) plus standard methadone maintenance treatment (treatment as usual [TAU]), (2) placebo plus TAU, (3) galantamine plus computerized CBT plus TAU, or (4) placebo plus computerized CBT plus TAU; medication administration was supervised at the time of daily methadone dosing. The primary cocaine use outcome was change in percent days of abstinence over time. Number of cocaine-negative urine toxicology screens submitted and cognitive function were secondary outcomes. RESULTS Random effect regression analysis indicated significant reductions in frequency of cocaine use over time, with significant treatment-by-time effects for both galantamine over placebo (F = 5.3, P = .02, d = 0.34) and computerized CBT over standard methadone treatment (F = 4.2, P = .04, d = 0.30) but no evidence of significant benefit of the combination over either treatment alone. Pretreatment to posttreatment comparisons of multiple indices of cognitive functioning, including sustained attention, indicated no benefit of galantamine over placebo. CONCLUSIONS Findings suggest benefits of galantamine and computerized CBT for reducing cocaine use in this sample. Although galantamine did not improve measures of cognitive function in this sample, multiple measures of cognitive function were associated with cocaine use outcomes, underlining the significance of cognitive function in cocaine treatment outcomes.

Abstract
Background: Over the past decade, availability and use of novel psychoactive substances such as synthetic cannabinoid receptor agonists (SCRA) have proliferated globally. However, the prevalence of SCRAs use remains uncertain, as does the degree to which individuals reporting SCRA use prefer SCRA to other drugs. Methods: In April 2017, a total of 500 anonymous surveys were completed by clients enrolled in a residential drug recovery program. Chi-square and t tests were used to examine significant differences between those who had ever used SCRA and those who had not. Logistic regression analysis was conducted in order to determine which other substances used within the past 12 months were significantly associated with past-12-month SCRA use. Results: About 69% (68.4%) of clients reported lifetime SCRA use. Those reporting SCRA use were predominantly younger ( x¯ = 32.5 vs. 40.7, P < .001), single (60.3% vs. 48.1%, P = .011), and white (87.1% vs. 77.7%, P = .008) and were more likely to have experienced past-12-month homelessness (6.5% vs. 3.2%, P = .004). This group had higher rates of probation/parole involvement (79.2% vs. 61.8%, P < .001) and incarceration (91.8% vs. 79.6%, P < .001). Individuals reporting SCRA use also showed extensive substance use histories and favored heroin, opioids, and amphetamines compared with SCRA. Only 5.2% of the SCRA-using group stated that SCRA was a preferred substance, and only 11.8% reported that they would try SCRA again. E-cigarettes (adjusted odds ratio [AOR] = 1.88), traditional cannabis (AOR = 3.87), amphetamines (AOR = 2.20), and synthetic cathinones (AOR = 3.51) were significantly associated with past-12-month SCRA use. Motivations for use included circumnavigating drug screens and peer influence. Approximately half of those who tried SCRA reported adverse effects associated with use. Conclusions: Prevalence of SCRA use among individuals with a history of substance misuse and criminal justice system involvement is high; however, SCRA are not indicated as a preferred drug.

Prevalence and motivations for kratom use in a sample of substance users enrolled in a residential treatment program. Drug Alcohol Depend 2017; 180:340-348.

Abstract
BACKGROUND Kratom use in the West has increased recently, yet the prevalence and motives for use among individuals with a history of substance use disorder (SUD) have not been fully examined. Kratom has been documented as a means of treating chronic pain, mitigating drug dependence, and easing withdrawal symptoms, yet it is unclear if substance users are utilizing kratom as a self-medication. Abuse liability, side effects, and overall appeal of kratom remain uncertain. METHODS In April 2017, an anonymous survey regarding kratom use and motivations was completed by clients enrolled in a 12-Step-oriented residential program. 500 respondents with a self-reported history of SUD completed the survey. RESULTS 20.8% of respondents endorsed lifetime kratom use and 10.2% reported past-12-month use. Kratom-users were younger (=32.1 vs. 35.9, p<0.001) and were more versatile substance users. A majority (68.9%) of kratom-users reported having used the drug as a means of reducing or abstaining from non-prescription opioids (NPO) and/or heroin, and 64.1% reported using kratom as a substitute for NPO/heroin. 18.4% of kratom-users reported using the drug due to a disability or chronic pain. One-third of kratom-users stated that kratom was a helpful substance and that they would try it again. However, kratom was not preferred and was indicated as having less appeal than NPO, heroin, amphetamines, and Suboxone. CONCLUSIONS Among substance users, kratom use may be initiated for a variety of reasons, including as a novel form of harm-reduction or drug substitution, particularly in the context of dependence and withdrawal from other substances.

Abstract
BACKGROUND The validity and concordance of two main measures of drug use behavior, self-report and urinalysis, has long been discussed. More understanding is needed about the underlying factors associated with discordance between these two methods. OBJECTIVES Describe the pattern and associated factors of discordance between self-reported heroin use and the urinalysis results of opiate use among methadone maintenance therapy (MMT) patients in China. METHODS A total of 2,448 MMT patients from 68 clinics in five provinces of China participated in a survey, which collected information on demographics, drug use and MMT-related factors, depressive symptoms, and drug avoidance self-efficacy. The most recent urine morphine test result was obtained from medical records and compared with self-reported heroin use. Participants who had urinalysis within 14 days of the survey were included in the analysis. RESULTS Among the 1,092 participants, 70 (6.4%) self-reported heroin use and 195 (17.9%) had positive urinalysis results. The over-reporters group had significantly higher education, and the under-reporters had significantly higher level of drug-avoidance self-efficacy and lower level of depressive symptoms. Among the participants who either self-reported heroin use or had positive urinalysis results, being young, having higher education, and having lower level of depressive symptoms were associated with discordance between self-reports and urinalysis results. CONCLUSION The combination of both measures in assessing drug use behavior seems necessary. The validity of self-report should be considered differently based on demographic and psychosocial characteristics.

Abstract
Use of novel psychoactive substances (NPS) such as synthetic cannabinoids (e.g., "Spice," "Serenity") and cathinones (e.g., "bath salts") has proliferated in recent years; however, there is a gap in research examining prevalence among offender samples. This study examined demographics, drug use, mental health characteristics, and criminal histories of NPS users compared to non-NPS users within an offender sample entering drug treatment. Using logistic regression analysis, combined 2013-2015 assessment data were examined (N = 8,791). NPS users offended more often (x̄ = 10.3), were more likely to have experienced homelessness (12.2%), and to have lived in a metro area (59.0%). NPS users reported significantly more past-year drug use, including substances not readily detected by standard urine analysis (e.g., hallucinogens, alcohol, and inhalants). Individuals with higher anxiety symptom counts (OR = 1.07; p < .001) and those who reported drinking to intoxication (OR = 1.30; p < .001) had an increased likelihood of NPS use. Older individuals (OR = 0.95; p < .001) and those who began using drugs at an older age (OR = 0.95; p < .001) were less likely to report NPS use. NPS use may be a marker of more severe using patterns in an offender sample. Future investigation should focus on NPS use as a possible method for bypassing drug testing measures.

Abstract
BACKGROUND This study evaluated the extent to which the addition of disulfiram and contingency management for adherence and abstinence (CM), alone and in combination, might enhance the effects of cognitive behavioral therapy (CBT) for cocaine use disorders. METHODS Factorial randomized double blind (for medication condition) clinical trial where CBT served as the platform and was delivered in weekly individual sessions in a community-based outpatient clinic. 99 outpatients who met DSM-IV criteria for current cocaine dependence were assigned to receive either disulfiram or placebo, and either CM or no CM. Cocaine and other substance use was assessed via a daily calendar with thrice weekly urine sample testing for 12 weeks with a one-year follow-up (80% interviewed at one year). RESULTS The primary hypothesis that CM and disulfiram would produce the best cocaine outcomes was not confirmed, nor was there a main effect for disulfiram. For the primary outcome (percent days of abstinence, self report), there was a significant interaction, with the best cocaine outcomes were seen for the combination of CM and placebo, with the two groups assigned to disulfiram associated with intermediate outcomes, and poorest cocaine outcome among those assigned to placebo and no CM. The secondary outcome (urinalysis) indicated a significant effect favoring CM over no CM but the interaction effect was not significant. One year follow-up data indicated sustained treatment effects across conditions. CONCLUSIONS CM enhances outcomes for CBT treatment of cocaine dependence, but disulfiram provided no added benefit to the combination of CM and CBT.

Abstract
BACKGROUND The confluence of drug use behaviors, sexual risk, and psychopathology may complicate human immunodeficiency virus (HIV) prevention intervention for adolescents engaging in substance use and criminal behavior. However, few studies have examined these risk associations. OBJECTIVE This study identified HIV risk behavior subgroups among adolescents in court-ordered substance abuse treatment and examined linkages with dimensions of internalizing and externalizing psychopathology. METHODS Internalizing and externalizing behaviors were assessed with the Millon Adolescent Clinical Inventory (MACI). Latent class analysis was used to identify subgroups on the basis of involvement in substance use proximal to sex, number of partners, and consistency of condom use. RESULTS Participants (n = 301) were identified as demonstrating high, medium, or low levels of sexual risk behavior. Greater externalizing psychopathology distinguished the high risk class from the medium risk class and from the low risk class. CONCLUSION Detained youth with particularly serious oppositional-defiant behavioral characteristics, substance use, and sex risk behavior likely require intensive interventions that address the multiple systemic factors that contribute to the development and maintenance of this pattern.

Decker SE, Frankforter T, Babuscio T, Nich C, Ball SA, Carroll KM. Assessment concordance and predictive validity of self-report and biological assay of cocaine use in treatment trials. Am J Addict 2014; 23:466-74. [PMID: 24628970 DOI: 10.1111/j.1521-0391.2014.12132.x] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2013] [Revised: 11/08/2013] [Accepted: 11/17/2013] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND AND OBJECTIVES Cocaine use during randomized clinical trials (RCTs) is typically assessed by participant self-report or biological assay (eg, urinalysis). There have been few direct comparisons of these assessment methods to investigate their concordance and their predictive validity for cocaine use and psychosocial outcomes following treatment completion. METHOD In a combined sample of 380 participants from 5 cocaine RCTs, the concordance between cocaine use assessment methods was examined. Sequential multiple linear and logistic regression models evaluated the predictive validity of two assessment methods for cocaine use and psychosocial outcomes assessed at 1, 3, 6, and 12 months after treatment. RESULTS Concordance for self-report and urinalysis indicators of cocaine use was high within-treatment (k = 0.72) and moderate during follow-up (k = 0.51). Rates of concordance were higher in studies using test cups with immediate urinalysis results. Regression analyses indicated that self-report data within-treatment predicted self-reported cocaine use at all post-treatment points (β 0.22-0.30, p < .01), while urinalysis results within-treatment predicted urinalysis results at 1, 3, and 6 months post-treatment (OR 3.92-20.99, p < .05). Cocaine-positive urinalyses within-treatment were negatively associated with a composite "good outcome" indicator at 1 and 3 months post-treatment (OR 0.17-0.32, p < .05). DISCUSSION AND CONCLUSIONS These results suggest a significant role of method variance in predicting post-treatment outcomes from within-treatment cocaine use indices. SCIENTIFIC SIGNIFICANCE Results support recommendations that cocaine treatment trials should include both biological assay and self-report assessment. Test cups may facilitate increased self-report accuracy.

Abstract
Background Addiction treatment faces high pretreatment and treatment dropout rates, especially among Aboriginals. In this study we examined characteristic differences between Aboriginal and non-Aboriginal clients accessing an inpatient medical withdrawal management program, and identified risk factors associated with the probabilities of pretreatment and treatment dropouts, respectively. Methods 2231 unique clients (Aboriginal = 451; 20%) referred to Vancouver Detox over a two-year period were assessed. For both Aboriginal and non-Aboriginal groups, multivariate logistic regression analyses were conducted with pretreatment dropout and treatment dropout as dependent variables, respectively. Results Aboriginal clients had higher pretreatment and treatment dropout rates compared to non-Aboriginal clients (41.0% vs. 32.7% and 25.9% vs. 20.0%, respectively). For Aboriginal people, no fixed address (NFA) was the only predictor of pretreatment dropout. For treatment dropout, significant predictors were: being female, having HCV infection, and being discharged on welfare check issue days or weekends. For non-Aboriginal clients, being male, NFA, alcohol as a preferred substance, and being on methadone maintenance treatment (MMT) at referral were associated with pretreatment dropout. Significant risk factors for treatment dropout were: being younger, having a preferred substance other than alcohol, having opiates as a preferred substance, and being discharged on weekends. Conclusions Our results highlight the importance of social factors for the Aboriginal population compared to substance-specific factors for the non-Aboriginal population. These findings should help clinicians and decision-makers to recognize the importance of social supports especially housing and initiate appropriate services to improve treatment intake and subsequent retention, physical and mental health outcomes and the cost-effectiveness of treatment.

Abstract
BACKGROUND Cocaine use remains a major problem within methadone maintenance programs. Disulfiram's efficacy in reducing cocaine use has been demonstrated in several trials, but its relative efficacy among individuals who use versus abstain from alcohol remains unclear. Treatment approaches which seek to enhance substance users' involvement in self-help activities (Twelve Step Facilitation, TSF) have been associated with better outcomes among alcohol and cocaine users, but have rarely been evaluated among methadone-maintained cocaine-opioid users. METHODS We conducted a randomized, placebo-controlled, double blind (for medication condition), factorial (2×2) trial with 4 treatment conditions: Disulfiram plus TSF, disulfiram plus standard counseling only, placebo plus TSF, and placebo plus standard counseling in the context of a community-based methadone maintenance program. Participants (N=112) received either disulfiram (250 mg/d) or placebo in conjunction with daily methadone maintenance. RESULTS Assignment to TSF was associated with less cocaine use throughout treatment and a higher number of cocaine-negative urines. While there were no significant main effects of disulfiram versus placebo, individuals without an alcohol use disorder demonstrated greater reductions in cocaine use over time when assigned to disulfiram. CONCLUSIONS TSF appears feasible in this methadone maintenance program and was associated with modest reductions in cocaine use, an often intractable problem in this setting. Support for the efficacy of disulfiram was weaker, as it appeared effective only for those without a current alcohol use disorder for this sample.

Abstract
Objective To assess concordance between self-reported amphetamine-type stimulant (ATS) use and toxicology results among young female sex workers (FSW) in Phnom Penh, Cambodia. Methods Cross-sectional data from the Young Women’s Health Study-2 (YWHS-2), a prospective study of HIV and ATS use among young (15 to 29 years) FSW in Phnom Penh, Cambodia, was analyzed. The YWHS-2 assessed sociodemographic characteristics, HIV serology, HIV risk, and ATS use by self-report and urine toxicology testing at each quarterly visit, the second of which provided data for this assessment. Outcomes include sensitivity, specificity, positive- and negative predictive values (overall and stratified by age), sex-work setting, and HIV status. Results Among 200 women, prevalence of positive toxicology screening for ATS use was 14% (95% confidence interval [CI], 9.2, 18.9%) and concurrent prevalence of self-reported ATS was 15.5% (95% CI, 10.4, 20.6%). The sensitivity and specificity of self-reported ATS use compared to positive toxicology test results was 89.3% (25/28), and 96.5% (166/172), respectively. The positive predictive value of self-reported ATS use was 80.6% (25/31); the negative predictive value was 98.2% (166/169). Some differences in concordance between self-report and urine toxicology results were noted in analyses stratified by age group and sex-work setting but not by HIV status. Conclusion Results indicate a high prevalence of ATS use among FSW in Phnom Penh, Cambodia, and high concordance between self-reported and toxicology-test confirmed ATS use.

Abstract
AIMS Clinical trials test the safety and efficacy of behavioral and pharmacological interventions in drug-dependent individuals. However, there is no consensus about the most appropriate outcome(s) to consider in determining treatment efficacy or on the most appropriate methods for assessing selected outcome(s). We summarize the discussion and recommendations of treatment and research experts, convened by the US National Institute on Drug Abuse, to select appropriate primary outcomes for drug dependence treatment clinical trials, and in particular the feasibility of selecting a common outcome to be included in all or most trials. METHODS A brief history of outcomes employed in prior drug dependence treatment research, incorporating perspectives from tobacco and alcohol research, is included. The relative merits and limitations of focusing on drug-taking behavior, as measured by self-report and qualitative or quantitative biological markers, are evaluated. RESULTS Drug-taking behavior, measured ideally by a combination of self-report and biological indicators, is seen as the most appropriate proximal primary outcome in drug dependence treatment clinical trials. CONCLUSIONS We conclude that the most appropriate outcome will vary as a function of salient variables inherent in the clinical trial, such as the type of intervention, its target, treatment goals (e.g. abstinence or reduction of use) and the perspective being taken (e.g. researcher, clinical program, patient, society). It is recommended that a decision process, based on such trial variables, be developed to guide the selection of primary and secondary outcomes as well as the methods to assess them.

Abstract
To reduce non-injection drug use (NIDU) among HIV primary care patients, more than a single brief intervention may be needed, but clinic resources are often too limited for extended interventions. To extend brief motivational interviewing (MI) to reduce NIDU, we designed and conducted a pilot study of "HealthCall," consisting of brief (1-3 minutes) daily patient calls reporting NIDU and health behaviors to a telephone-based interactive voice response (IVR) system, which provided data for subsequent personalized feedback. Urban HIV adult clinic patients reporting ≥4 days of NIDU in the previous month were randomized to two groups: MI-only (n=20) and MI+HealthCall (n=20). At 30 and 60 days, patients were assessed and briefly discussed their NIDU behaviors with their counselors. The outcome was the number of days patients used their primary drug in the prior 30 days. Medical marijuana issues precluded HealthCall with patients whose primary substance was marijuana (n=7); excluding these, 33 remained, of whom 28 patients (MI-only n=17; MI+HealthCall n=11) provided post-treatment data for analysis. Time significantly predicted reduction in "days used" in both groups (p<0.0001). At 60 days, between-group differences approached trend level, with an effect size of 0.62 favoring the MI+HealthCall arm. This pilot study suggests that HealthCall is feasible and acceptable to patients in resource-limited HIV primary care settings and can extend patient involvement in brief intervention with little additional staff time. A larger efficacy trial of HealthCall for NIDU-reduction in such settings is warranted.

Abstract
The study examined the validity of 1848 self-reported uses of drugs determined within an Addiction Severity Index interview in comparison with urinalysis results among drug-dependent subjects undergoing treatment in outpatient clinics (Aquitaine area, southwest France, 1994-2005). Agreement and kappa statistics were calculated for each substance. Factors associated with agreement were defined using a multivariate analysis. The conditional kappa coefficients were excellent for all substances assessed. The accuracy between self-reports and urinalysis results was influenced by factors that only slightly affected conditional kappa coefficients. Clients did not underreport their substance use in naturalistic clinical assessment conditions.

Abstract
BACKGROUND Buprenorphine/naloxone allows the integration of opioid dependence and HIV treatment. METHODS We conducted a prospective study in HIV-infected opioid-dependent patients to investigate the impact of buprenorphine/naloxone treatment on drug use. Self-report and chart review assessments were conducted every 3 months (quarters 1-4) for 1 year. Outcomes were buprenorphine/naloxone treatment retention, drug use, and addiction treatment processes. RESULTS Among 303 patients enrolled between July 2005 and December 2007, retention in buprenorphine/naloxone treatment was 74%, 67%, 59%, and 49% during Quarters 1, 2, 3, and 4, respectively. Past 30-day illicit opioid use decreased from 84% of patients at baseline to 42% in retained patients over the year. Patients were 52% less likely to use illicit opioids for each quarter in treatment (Odds ratio = 0.66; 95% CI: 0.61 to 0.72). Buprenorphine/naloxone doses and office visits approximated guidelines published by the United States Department of Health and Human Services. Urine toxicology monitoring was less frequent than recommended. CONCLUSIONS Buprenorphine/naloxone provided in HIV treatment settings can decrease opioid use. Strategies are needed to improve retention and address ongoing drug use in this treatment population.

Abstract
Information about treatment services can be ascertained in several ways. We examine the level of agreement among data on substance user treatment services collected via multiple methods and respondents in the nationally representative Alcohol and Drug Services Study (ADSS, 1996-1999), and potential reasons for discrepancies. Data were obtained separately from facility director reports, treatment record abstracts, and client interviews. Concordance was generally acceptable across methods and respondents. Although any of these methods should be adequate, additional information is gleaned from multiple sources.

Abstract
AIMS To evaluate the changes over time in quality and quantity of coping skills acquired following cognitive behavioral therapy (CBT), and examine potential mediating effects on substance use outcomes. DESIGN A randomized controlled trial (RCT) evaluating the effectiveness of a computerized version of CBT (CBT4CBT) as an adjunct to standard out-patient treatment over an 8-week period. SETTING Data were collected from individuals seeking treatment for substance dependence in an out-patient community setting. PARTICIPANTS Fifty-two substance abusing individuals (50% African American), with an average age of 42 years, and a majority reporting cocaine as their primary drug of choice. MEASUREMENTS Participants' responses to behavioral role-plays of situations associated with high risk for drug and alcohol use were audio-taped and rated independently to assess their coping responses. FINDINGS There were statistically significant increases in mean ratings of the quality of participants' coping responses for those assigned to CBT4CBT compared to treatment as usual, and these differences remained significant 3 months after treatment completion. Moreover, quality of coping responses mediated the effect of treatment on participants' duration of abstinence during the follow-up period. CONCLUSIONS These findings suggest that assignment to the computerized CBT program improved participants' coping skills, as measured by independent ratings of a role-playing task. It is also the first study to test and support quality of coping skills acquired as a mediator of the effect of CBT for substance use.

Abstract
INTRODUCTION Many factors comprise a patient's decision to disclose use of drugs. Pregnant women may report drug use because they would like help with their addiction but the stigma associated with drug use may dampen their willingness to disclose. Knowledge about the accuracy of self-reported drug use as compared to urine toxicology screens can assist clinicians in the management of substance use in pregnancy. METHOD We compared the urine toxicology screens and self-reported use of marijuana or cocaine for 168 women enrolled in an integrated obstetrical/substance abuse treatment program. We stratified by various periods of self-reported use and race and utilized Cohen's kappa to measure overall agreement between self-report and toxicology tests. RESULTS Most women with a positive toxicology screen reported use in the past 28 days (78% for marijuana, 86% for cocaine). However, many women reported their most recent use to be outside of the assays' detection window (14% for marijuana, 57% for cocaine). We did not find differences in self-report for women with positive urine between Whites and non-Whites (p = 1.00). Agreement over the previous month was good (Kappa = 0.74 and 0.70 for marijuana and cocaine, respectively.). SUMMARY A question about use of marijuana or cocaine during the preceding month rather than the prior few days may be a better indicator of use.

Abstract
The value of hair analysis in measuring treatment outcome was examined in a randomised controlled trial (RCT) of an Australian state prison-based methadone programme between 1997 and 1998 (n = 382 male prisoners). Hair samples were analysed for morphine using immunoassay techniques. Agreement between hair analysis and self-report was tested using kappa, McNemar's test of symmetry and Pearson's correlation coefficient r. Hair analysis based on immunoassay was inadequate as the primary outcome measure for the RCT but had value in supplementing self-reported heroin use. There was a modest correlation (r = 0.31, p < 0.001) between self-reported frequency of heroin use and morphine concentrations in hair. Sectional hair analysis, a reflection of duration of drug use, was uninformative and generally impractical due to the length of hair sections needed.

Abstract
OBJECTIVES This study sought to document the trends in drug use among intravenous drug users (IDUs) in northern British Columbia, and to discuss the public health implications. METHOD We conducted a 7-year medical-chart review of all IDU-related admissions (n = 2072) to an inpatient alcohol and drug detoxification centre in Prince George, British Columbia. Primary detoxification diagnosis was modeled onto year of admission using generalized estimating equations (GEE). RESULTS Our study demonstrated an increasing prevalence of cocaine as the primary detoxification diagnosis in IDU-related admissions in northern BC, from 32% of all IDU admissions in 1999 to 64% in 2001, and then a relatively steady elevated rate of approximately 60% between 2001-2005. CONCLUSIONS Given that needle exchange programs and other harm reduction services for IDUs in British Columbia are not readily available in many northern and rural areas, the risks associated with intravenous cocaine use among northern IDUs represent a serious public health challenge. Tailored harm reduction strategies should take into account the prominence of intravenous cocaine use as an HIV risk factor. In areas without well-established intravenous drug use monitoring programs, such as rural and remote areas, detoxification treatment records may serve as important sentinels for changing drug use patterns among IDUs.

Abstract
OBJECTIVES This study evaluated the efficacy of a computer-based version of cognitive-behavioral therapy (CBT) for substance dependence. METHOD This was a randomized clinical trial in which 77 individuals seeking treatment for substance dependence at an outpatient community setting were randomly assigned to standard treatment or standard treatment with biweekly access to computer-based training in CBT (CBT4CBT) skills. RESULTS Treatment retention and data availability were comparable across the treatment conditions. Participants assigned to the CBT4CBT condition submitted significantly more urine specimens that were negative for any type of drugs and tended to have longer continuous periods of abstinence during treatment. The CBT4CBT program was positively evaluated by participants. In the CBT4CBT condition, outcome was more strongly associated with treatment engagement than in treatment as usual; furthermore, completion of homework assignments in CBT4CBT was significantly correlated with outcome and a significant predictor of treatment involvement. CONCLUSIONS These data suggest that CBT4CBT is an effective adjunct to standard outpatient treatment for substance dependence and may provide an important means of making CBT, an empirically validated treatment, more broadly available.

Abstract
This is a randomized, double-blind, placebo-controlled clinical trial that evaluated the efficacy of a higher-than-typical daily dose of naltrexone (150 mg/day), taken for 12 weeks, in 164 patients (n = 116 men and n = 48 women) with co-occurring cocaine and alcohol dependence. Patients were stratified by gender and then randomly assigned to either naltrexone or placebo, and to either cognitive-behavioral therapy or a type of medical management. The two primary outcomes were cocaine use and alcohol use. Significant Gender x Medication interactions were found for cocaine use via urine drug screens (three way, with time) and self-reports (two way) for drug severity (two way) and alcohol use (two way). The type of psychosocial treatment did not affect outcomes. Thus, 150 mg/day naltrexone added to a psychosocial treatment resulted in reductions in cocaine and alcohol use and drug severity in men, compared to higher rates of cocaine and alcohol use and drug severity in women.

Abstract
BACKGROUND This is a double blind, placebo-controlled trial that evaluated the efficacy of disulfiram, naltrexone and their combination in patients with co-occurring cocaine and alcohol dependence. METHODS 208 patients were randomized to disulfiram (250 mg/day), naltrexone (100 mg/day), the combination, or placebo for 11 weeks. Outcomes were in-trial abstinence from cocaine and/or alcohol. RESULTS Few safety concerns were reported, although medication adherence was low in a number of patients for both medications, alone or in combination. In the primary analyses (GEE modeling), abstinence from cocaine as measured by cocaine-negative urines and days of self-reported abstinence from cocaine or alcohol did not differ between placebo and any of the medication groups. However, patients taking disulfiram (alone or in combination) were most likely to achieve combined abstinence from cocaine and alcohol. Secondary analyses revealed that patients taking the disulfiram-naltrexone combination were most likely to achieve 3 consecutive weeks of abstinence from cocaine and alcohol. CONCLUSION There was an association between disulfiram treatment and abstinence from cocaine and alcohol. More patients taking the disulfiram-naltrexone combination achieved 3 consecutive weeks of abstinence in treatment than placebo-treated patients.

Abstract
The aims of this study were to identify factors associated with pretreatment and treatment dropouts among individuals accessing an inpatient medical withdrawal management program (Vancouver Detox). Two thousand five hundred sixty-six unique clients, who were referred to Vancouver Detox over two-year period, were assessed. Demographic and drug related variables were analyzed as possible risk factors, and two multivariate logistic regression analyses were conducted. We found that being male, being aboriginal, having no children, no fixed address, alcohol as a preferred substance, and being on methadone maintenance treatment at referral were significantly associated with high pretreatment dropout. Significant risk factors for treatment dropout were: being younger, having HCV infection, having a preferred substance other than alcohol, having opiates as a preferred substance, and being discharged on welfare check issue periods or weekends. These findings may help clinicians and decision-makers to initiate corresponding preventive measures to decrease unnecessary attritions and improve utilization of treatment resources.

Abstract
The 'Athena' service is an abstinence-oriented, outpatient substance addiction unit in Greece. To appraise the operation of the service, 459 clients who contacted the unit during a 3-yr. period were assessed in terms of treatment retention and situation upon discharge from the program; 182 of them had four or more appointments with the service and were thoroughly assessed using a battery of measures pertaining to their situation at discharge and their patterns of abuse and related problems. Most help-seekers were single, unemployed, young men who regularly used heroin (89%) intravenously (35%). From those who got involved in the therapeutic process (40%), 72% had positively modified their drug abuse by the time of discharge from the program (mean duration of treatment: approx. three months); the largest improvement (42%) was recorded in their psychological condition. Treatment retention was significantly higher for cannabis abusers than heroin addicts; longer treatment duration was significantly associated with a positive situation at discharge, while higher education was associated with a less favorable outcome regarding the abuse of the principal substance. These findings suggest that such outpatient programs may help a significant number of individuals who get involved in the therapeutic process and should be considered effective for treatment of substance abuse among the diversity of treatment modalities.

Abstract
Psychoactive substance use is a risk factor for suicidal behavior and current intoxication increases the likelihood of serious intentional drug overdose (IDO). The objective was to assess the accuracy of information on substance use recorded in medical charts using toxicological assays as a reference in subjects admitted for IDO to an emergency department. Patients (n=1190) consecutively admitted for IDO were included. Information on substance use was recorded in routine practice by the emergency staff and toxicological assays (cannabis, opiate, buprenorphine, amphetamine/ecstasy, cocaine, LSD) were carried out in urine samples collected as part of routine management. The information on substance use was recorded in medical charts for 24.4% of subjects. A third of subjects (27.5%) were positive for toxicological assays. Recorded substance use allowed correct classification of nearly 80% of subjects. However, specificity (88.6%) was better than sensitivity (54.2%). Compared with toxicological assays, medical records allowed identification of only half of the subjects with current substance use. The usefulness of systematic toxicological assays during hospitalization for IDO should be assessed in further studies exploring whether such information allows medical management to be modified and contributes to improving prognosis.

Abstract
The current study aimed to compare self-reported injecting and sexual risk behaviour among Needle and Syringe Program (NSP) attendees who self-completed a questionnaire to that of those who received assistance in completing the questionnaire. Information on demographic, injecting and sexual risk behaviour was collected via a self-completed questionnaire for an annual cross-sectional survey of injecting drug users (IDUs) recruited from sentinel NSPs around Australia. Assistance was provided when necessary and recorded. Of 2,035 participants, 1,452 (71%) reported completing the questionnaire without assistance. Being male and nominating a language other than English spoken at home was independently associated with receiving assistance with questionnaire completion. Participants who reported heroin as the drug last injected were also more likely to receive assistance. Multivariate analyses revealed those who received assistance with questionnaire completion were less likely to report re-using a syringe after someone else and less likely to report sex work in the past month. The current findings suggest self-completion of risk behaviour questionnaires should be considered as an alternative to interviewer administered questionnaires to maximise accuracy of self-reports.

Abstract
This study examined gender differences within a sample of Canadian Aboriginal individuals admitted to an inpatient, hospital-based substance abuse detoxification program. Even though alcohol was the most frequent primary drug of detoxification for both genders, women received proportionately higher rates of cocaine or opiate detoxification diagnoses. In addition to a younger age, females reported higher rates of physical and sexual abuse. Women were also administered antidepressants, antibiotic medication protocols, and more medical evaluation tests. It appears that Canadian Aboriginal women have a diverse set of psychological and medical needs. This study demonstrates the need for detoxification programs to address the substantial rates of intravenous drug use and the associated risk of infectious disease (eg, Hepatitis C, HIV) among this treatment-seeking population.

Abstract
Marijuana-dependent young adults (N = 136), all referred by the criminal justice system, were randomized to 1 of 4 treatment conditions: a motivational/skills-building intervention (motivational enhancement therapy/cognitive-behavioral therapy; MET/CBT) plus incentives contingent on session attendance or submission of marijuana-free urine specimens (contingency management; CM), MET/CBT without CM, individual drug counseling (DC) plus CM, and DC without CM. There was a significant main effect of CM on treatment retention and marijuana-free urine specimens. Moreover, the combination of MET/CBT plus CM was significantly more effective than MET/CBT without CM or DC plus CM, which were in turn more effective than DC without CM for treatment attendance and percentage of marijuana-free urine specimens. Participants assigned to MET/CBT continued to reduce the frequency of their marijuana use through a 6-month follow-up.

Abstract
BACKGROUND Heroin dependence is a chronic relapsing disease often requiring multiple treatment experiences. Despite this knowledge, few methadone programs follow-up with discharged patients who frequently continue to engage in risky behaviors. The aim of this project was to evaluate the effectiveness of outreach case management for post-discharged methadone patients. METHODS At 90 days post-discharge 128 active out of treatment heroin users were randomly assigned to receive either a passive referral (PR) for drug treatment (n=52) or were provided with 6 weeks of outreach case management (OCM), an intervention designed to help motivate and coach patients to re-enter treatment (n=76). RESULTS At 6 months post-baseline 29% of the OCM participants had successfully re-enrolled in drug treatment compared to 8% of the PR participants (chi(2)=7.6, d.f.=1, p=0.006). A logistic regression analysis showed that OCM participants were nearly six times more likely than PR participants to re-engage in MMT (OR=5.8, CI=1.6-20.8, p=0.008). Moreover, OCM subjects had fewer opiate and cocaine positive urines at the 6-month follow-up compared to PR subjects. CONCLUSIONS The findings highlight the importance of engaging former patients in treatment and actively assisting in treatment re-entry. OCM is a simple approach to reduce the number of out-of-treatment drug users, although availability of treatment funding limits enrollment opportunities.

Abstract
Despite recent emphasis on integrating empirically validated treatment into clinical practice, there are little data on whether manual-guided behavioral therapies can be implemented in standard clinical practice and whether incorporation of such techniques is associated with improved outcomes. The effectiveness of integrating motivational interviewing (MI) techniques into the initial contact and evaluation session was evaluated in a multisite randomized clinical trial. Participants were 423 substance users entering outpatient treatment in five community-based treatment settings, who were randomized to receive either the standard intake/evaluation session at each site or the same session in which MI techniques and strategies were integrated. Clinicians were drawn from the staff of the participating programs and were randomized either to learn and implement MI or to deliver the standard intake/evaluation session. Independent analyses of 315 session audiotapes suggested the two forms of treatment were highly discriminable and that clinicians trained to implement MI tended to have higher skill ratings. Regarding outcomes, for the sample as a whole, participants assigned to MI had significantly better retention through the 28-day follow-up than those assigned to the standard intervention. There were no significant effects of MI on substance use outcomes at either the 28-day or 84-day follow-up. Results suggest that community-based clinicians can effectively implement MI when provided training and supervision, and that integrating MI techniques in the earliest phases of treatment may have positive effects on retention early in the course of treatment.

Abstract
Mid-way through the third decade of experience in preventing HIV/AIDS among adolescents, behavioral interventions and outcomes for high risk subgroups have generated evidence extremely instructive for navigating future priorities in reducing transmission risk behavior. Youth who abuse alcohol or drugs, who are detained or incarcerated, or have mental health co-morbidity such as externalizing disorders, represent the most significant challenge to current and future efforts to control the epidemic among the adolescent population. Although there is no unambiguous, standard intervention approach with adolescents, patterns of risks and outcomes with these subgroups are instructive in the critical priority of creating more sustainable gains with our HIV prevention resources. This article provides a synthesis of the evidence with these subgroups, discusses important limitations and difficulties in the current intervention science and highlights promising directions for the next generation of effort in reducing adolescent HIV-related sexual risk behavior. Because individual-level interventions have had only modest effects, a key current emphasis within the field is to develop multilevel interventions with a more ecological or contextual focus. We review various pragmatic responses that acknowledge this priority and the debt owed to individual-level intervention work with adolescents.

Abstract
CONTEXT Disulfiram has emerged as a promising treatment for cocaine dependence, but it has not yet been evaluated in general populations of cocaine users. OBJECTIVES To compare the effectiveness of disulfiram therapy with that of a placebo condition in reducing cocaine use and to compare the effectiveness of 2 active behavioral therapies-cognitive behavior therapy (CBT) and interpersonal psychotherapy (IPT)-in reducing cocaine use. DESIGN Randomized, placebo-controlled, double-masked (for medication condition), factorial (2 x 2) trial with 4 treatment conditions: disulfiram plus CBT, disulfiram plus IPT, placebo plus CBT, and placebo plus IPT. SETTING A community-based outpatient substance abuse treatment program. PATIENTS A total of 121 individuals meeting the criteria for current cocaine dependence. INTERVENTIONS Patients received either disulfiram (250 mg/d) or placebo in identical capsules. Medication compliance was monitored using a riboflavin marker procedure. Both behavioral therapies (CBT and IPT) were manual guided and were delivered in individual sessions for 12 weeks. MAIN OUTCOME MEASURES Random regression analyses of self-reported frequency of cocaine use and results of urine toxicology screens. RESULTS Participants assigned to disulfiram reduced their cocaine use significantly more than those assigned to placebo, and those assigned to CBT reduced their cocaine use significantly more than those assigned to IPT (P<.01 for both). Findings were consistent across all study samples (eg, intention to treat, treatment initiators, and treatment completers). Benefits of disulfiram use and CBT were most pronounced for participants who were not alcohol dependent at baseline or who fully abstained from drinking alcohol during treatment. Adverse effects experienced by participants who received disulfiram were mild and were not considerably different from those experienced by participants who received placebo. CONCLUSIONS Disulfiram and CBT are effective therapies for general populations of cocaine-dependent individuals. Disulfiram seems to exert a direct effect on cocaine use rather than through reducing concurrent alcohol use.

Abstract
The present study assessed drug use and the validity of self-reports of drug use among young people seeking treatment. On admission the participants (n = 316), 215 males and 101 females, were interviewed about their drug use. Urine samples were collected to screen for alcohol, amphetamine, benzodiazepines, cannabis, cocaine, methylenedioxymethamphetamine (MDMA) and opiate use. Self-reports of substance use were compared with urinalysis results. Seventy-three percent of the participants reported use of two or more substances. Single substance users were primarily alcohol users. Kappa agreement between self-report and urinalysis results was of acceptable concordance (> or = 0.65) except for alcohol (kappa = 0.19). Conditional kappa values were good (> or = 0.85) with exception of opiates (cond. kappa = 0.57). The self-reports were generally reliable among young people seeking treatment. No significant differences (p > or = 0.54) were found in the validity of self-reports between the genders.

Abstract
Workplace drug testing programs are often met with intense criticism. Despite resistance among labor and consumer groups and a lack of rigorous empirical evidence regarding effectiveness, drug testing programs have remained popular with employers throughout the 1990s and into the current century. The present study analyzed nationally representative data on over 15,000 US households to determine whether various types of workplace drug testing programs influenced the probability of drug use by workers. The study estimated several empirical specifications using both univariate and bivariate probit techniques. The specification tests favored the bivariate probit model over the univariate probit model. Estimated marginal effects of drug testing on any drug use were negative, significant, and relatively large, indicating that drug testing programs are achieving one of the desired effects. The results were similar when any drug use was replaced with chronic drug use in the models. These results have important policy implications regarding the effectiveness and economic viability of workplace anti-drug programs.

Abstract
Vocational rehabilitation (VR) programs within addiction treatment traditionally consider employment as the desired outcome. This singular focus ignores other benefits, such as.reduced substance use. A framework for evaluating the cost-effectiveness of VR within addiction treatment is presented and illustrated with data from the Alcohol and Drug Services Study (ADSS, 1996--1999). VR was associated with a 2.5% increase in probability of abstinence at an $883 increase in cost per admission. Thus, the estimated cost-effectiveness of VR in promoting abstinence is $35,000 per additional abstinent client ($883/0.025), indicating that VR is a cost-effective contributor to other goals of addiction treatment.
