Abstract
BACKGROUND Stimulant use disorder is a continuously growing medical and social burden without approved medications available for its treatment. Psychosocial interventions could be a valid approach to help people reduce or cease stimulant consumption. This is an update of a Cochrane review first published in 2016. OBJECTIVES To assess the efficacy and safety of psychosocial interventions for stimulant use disorder in adults. SEARCH METHODS We searched the Cochrane Drugs and Alcohol Group Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, three other databases, and two trials registers in September 2023. All searches included non-English language literature. We handsearched the references of topic-related systematic reviews and the included studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing any psychosocial intervention with no intervention, treatment as usual (TAU), or a different intervention in adults with stimulant use disorder. DATA COLLECTION AND ANALYSIS We used the standard methodological procedures expected by Cochrane. MAIN RESULTS We included a total of 64 RCTs (8241 participants). Seventy-three percent of studies included participants with cocaine or crack cocaine use disorder; 3.1% included participants with amphetamine use disorder; 10.9% included participants with methamphetamine use disorder; and 12.5% included participants with any stimulant use disorder. In 18 studies, all participants were in methadone maintenance treatment. In our primary comparison of any psychosocial treatment to no intervention, we included studies which compared a psychosocial intervention plus TAU to TAU alone. In this comparison, 12 studies evaluated cognitive behavioural therapy (CBT), 27 contingency management, three motivational interviewing, one study looked at psychodynamic therapy, and one study evaluated CBT plus contingency management. We also compared any psychosocial intervention to TAU. In this comparison, seven studies evaluated CBT, two contingency management, two motivational interviewing, and one evaluated a combination of CBT plus motivational interviewing. Seven studies compared contingency management reinforcement related to abstinence versus contingency management not related to abstinence. Finally, seven studies compared two different psychosocial approaches. We judged 65.6% of the studies to be at low risk of bias for random sequence generation and 19% at low risk for allocation concealment. Blinding of personnel and participants was not possible for the type of intervention, so we judged all the studies to be at high risk of performance bias for subjective outcomes but at low risk for objective outcomes. We judged 22% of the studies to be at low risk of detection bias for subjective outcomes. We judged most of the studies (69%) to be at low risk of attrition bias. When compared to no intervention, we found that psychosocial treatments: reduce the dropout rate (risk ratio (RR) 0.82, 95% confidence interval (CI) 0.74 to 0.91; 30 studies, 4078 participants; high-certainty evidence); make little to no difference to point abstinence at the end of treatment (RR 1.15, 95% CI 0.94 to 1.41; 12 studies, 1293 participants; high-certainty evidence); make little to no difference to point abstinence at the longest follow-up (RR 1.22, 95% CI 0.91 to 1.62; 9 studies, 1187 participants; high-certainty evidence); probably increase continuous abstinence at the end of treatment (RR 1.89, 95% CI 1.20 to 2.97; 12 studies, 1770 participants; moderate-certainty evidence); may make little to no difference in continuous abstinence at the longest follow-up (RR 1.14, 95% CI 0.89 to 1.46; 4 studies, 295 participants; low-certainty evidence); reduce the frequency of drug intake at the end of treatment (standardised mean difference (SMD) -0.35, 95% CI -0.50 to -0.19; 10 studies, 1215 participants; high-certainty evidence); and increase the longest period of abstinence (SMD 0.54, 95% CI 0.41 to 0.68; 17 studies, 2118 participants; high-certainty evidence). When compared to TAU, we found that psychosocial treatments reduce the dropout rate (RR 0.79, 95% CI 0.65 to 0.97; 9 studies, 735 participants; high-certainty evidence) and may make little to no difference in point abstinence at the end of treatment (RR 1.67, 95% CI 0.64 to 4.31; 1 study, 128 participants; low-certainty evidence). We are uncertain whether they make any difference in point abstinence at the longest follow-up (RR 1.31, 95% CI 0.86 to 1.99; 2 studies, 124 participants; very low-certainty evidence). Compared to TAU, psychosocial treatments may make little to no difference in continuous abstinence at the end of treatment (RR 1.18, 95% CI 0.92 to 1.53; 1 study, 128 participants; low-certainty evidence); probably make little to no difference in the frequency of drug intake at the end of treatment (SMD -1.17, 95% CI -2.81 to 0.47, 4 studies, 479 participants, moderate-certainty evidence); and may make little to no difference in the longest period of abstinence (SMD -0.16, 95% CI -0.54 to 0.21; 1 study, 110 participants; low-certainty evidence). None of the studies for this comparison assessed continuous abstinence at the longest follow-up. Only five studies reported harms related to psychosocial interventions; four of them stated that no adverse events occurred. AUTHORS' CONCLUSIONS This review's findings indicate that psychosocial treatments can help people with stimulant use disorder by reducing dropout rates. This conclusion is based on high-certainty evidence from comparisons of psychosocial interventions with both no treatment and TAU. This is an important finding because many people with stimulant use disorders leave treatment prematurely. Stimulant use disorders are chronic, lifelong, relapsing mental disorders, which require substantial therapeutic efforts to achieve abstinence. For those who are not yet able to achieve complete abstinence, retention in treatment may help to reduce the risks associated with stimulant use. In addition, psychosocial interventions reduce stimulant use compared to no treatment, but they may make little to no difference to stimulant use when compared to TAU. The most studied and promising psychosocial approach is contingency management. Relatively few studies explored the other approaches, so we cannot rule out the possibility that the results were imprecise due to small sample sizes.

Abstract
BACKGROUND Cocaine is a psychostimulant used by approximately 0.4% of the general population worldwide. Cocaine dependence is a chronic mental disorder characterised by the inability to control cocaine use and a host of severe medical and psychosocial complications. There is current no approved pharmacological treatment for cocaine dependence. Some researchers have proposed disulfiram, a medication approved to treat alcohol use disorder. This is an update of a Cochrane review first published in 2010. OBJECTIVES To evaluate the efficacy and safety of disulfiram for the treatment of cocaine dependence. SEARCH METHODS We updated our searches of the following databases to August 2022: the Cochrane Drugs and Alcohol Group Specialised Register, CENTRAL, MEDLINE, Embase, CINAHL, and PsycINFO. We also searched for ongoing and unpublished studies via two trials registries. We handsearched the references of topic-related systematic reviews and included studies. The searches had no language restrictions. SELECTION CRITERIA We included randomised controlled trials that evaluated disulfiram alone or associated with psychosocial interventions versus placebo, no intervention, other pharmacological interventions, or any psychosocial intervention for the treatment of cocaine dependence. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. MAIN RESULTS Thirteen studies (1191 participants) met our inclusion criteria. Disulfiram versus placebo or no treatment Disulfiram compared to placebo may increase the number of people who are abstinent at the end of treatment (point abstinence; risk ratio (RR) 1.58, 95% confidence interval (CI) 1.05 to 2.36; 3 datasets, 142 participants; low-certainty evidence). However, compared to placebo or no pharmacological treatment, disulfiram may have little or no effect on frequency of cocaine use (standardised mean difference (SMD) -0.11 standard deviations (SDs), 95% CI -0.39 to 0.17; 13 datasets, 818 participants), amount of cocaine use (SMD -0.00 SDs, 95% CI -0.30 to 0.30; 7 datasets, 376 participants), continuous abstinence (RR 1.23, 95% CI 0.80 to 1.91; 6 datasets, 386 participants), and dropout for any reason (RR 1.20, 95% CI 0.92 to 1.55; 14 datasets, 841 participants). The certainty of the evidence was low for all these outcomes. We are unsure about the effects of disulfiram versus placebo on dropout due to adverse events (RR 12.97, 95% CI 0.77 to 218.37; 1 study, 67 participants) and on the occurrence of adverse events (RR 3.00, 95% CI 0.35 to 25.98), because the certainty of the evidence was very low for these outcomes. Disulfiram versus naltrexone Disulfiram compared with naltrexone may reduce the frequency of cocaine use (mean difference (MD) -1.90 days, 95% CI -3.37 to -0.43; 2 datasets, 123 participants; low-certainty evidence) and may have little or no effect on amount of cocaine use (SMD 0.12 SDs, 95% CI -0.27 to 0.51, 2 datasets, 123 participants; low-certainty evidence). We are unsure about the effect of disulfiram versus naltrexone on dropout for any reason (RR 0.86, 95% CI 0.56 to 1.32, 3 datasets, 131 participants) and dropout due to adverse events (RR 0.50, 95% CI 0.07 to 3.55; 1 dataset, 8 participants), because the certainty of the evidence was very low for these outcomes. AUTHORS' CONCLUSIONS Our results show that disulfiram compared to placebo may increase point abstinence. However, disulfiram compared to placebo or no pharmacological treatment may have little or no effect on frequency of cocaine use, amount of cocaine use, continued abstinence, and dropout for any reason. We are unsure if disulfiram has any adverse effects in this population. Caution is required when transferring our results to clinical practice.

Drug Alcohol Depend 2023; 248:109947. [PMID: 37276806 PMCID: PMC10498479 DOI: 10.1016/j.drugalcdep.2023.109947] [Citation(s) in RCA: 1] [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: 11/22/2022] [Revised: 05/03/2023] [Accepted: 05/23/2023] [Indexed: 06/07/2023]
Abstract
BACKGROUND This study examined a threshold based on the percentage of cocaine-negative (CN) urine drug screens (UDS) collected during treatment as a potential meaningful endpoint for clinical trials. We hypothesized that individuals providing at least 75% CN UDS would have better long-term outcomes than those providing less than 75% CN UDS. METHODS Two separate pooled datasets of randomized clinical trials conducted at different institutions were used for analyses: one composed of eight trials (N = 760) and the other composed of three trials (N = 416), all evaluating behavioral and/or pharmacological treatments for cocaine use. UDS were collected at least once per week (up to three times per week) during the 8- or 12-week treatment period across all trials, with substance use and psychosocial functioning measured up to 12 months following treatment. Chi-squares and ANOVAs compared within-treatment and follow-up outcomes between the groups. RESULTS Compared to those who did not achieve the threshold, participants who achieved the 75%-CN threshold were retained in treatment longer and had a longer period of continuous abstinence, and were more likely to report problem-free functioning. Additionally, participants who achieved the 75%-CN threshold were more likely to report sustained abstinence and better psychosocial functioning throughout a follow-up period up to 12 months than those who did not achieve the threshold. CONCLUSIONS A threshold of 75%-CN UDS is associated with short- and long-term clinical benefits. Future clinical trials may consider this a meaningful threshold for defining treatment responders.

Abstract
AIMS To estimate the efficacy of multiple psychosocial interventions for opioid-dependent people receiving methadone maintenance treatment (MMT). METHODS Systematic review and network meta-analysis of randomized controlled trials (RCTs) reporting the effect of psychosocial intervention for opioid-dependent people receiving MMT in outpatient clinics. We searched multiple data sources (Medline, Embase, Web of Science, PsycINFO and Cochrane Library) from inception to January 2022, finding 21 RCTs evaluating a total of 2862 people with opioid dependence receiving MMT. The primary outcome was the opioid-positive rate (assessed by urinalysis) and the secondary outcome was treatment discontinuation (the number of patients who terminated the study for any reason). We performed random-effects Bayesian meta-analysis. We used relative ranking using surface under the cumulative ranking method and certainty of evidence using grading of recommendations, assessment, development and evaluations. RESULTS Cognitive-behavioral therapy (CBT) [odds ratio (OR) = 0.66, 95% credible interval (CI) = 0.66-0.96; low certainty] and educational and behavioral counseling (EBC) (OR = 0.28, 95% CI = 0.12-0.25; high certainty) were more effective than treatment as usual (TAU) in efficacy. In terms of treatment discontinuation, at the end of the follow-up period there was no statistical significance among psychosocial interventions. According to the ranking probabilities, EBC might be the most effective treatment and behavioral couples' therapy (BCT) might be the best discontinuation treatment. CONCLUSIONS Educational and behavioral counseling and cognitive-behavioral therapy appear to be the most effective psychosocial interventions for opioid-dependent people receiving methadone maintenance treatment.

Abstract
Stimulant use disorder (SUD) is a public health problem in the United States that is associated with increased morbidity and mortality. Psychosocial interventions, such as cognitive behavioral therapy and contingency management, are the main treatment modality for SUDs and no pharmacotherapy is currently FDA approved for this indication. Although some medications show promising data for the treatment of SUD, the evidence remains inconsistent, and the clinical application is limited due to the heterogenicity of the population and the lack of studies in patients with various comorbidities. Selection of pharmacotherapy treatment for methamphetamine intoxication, persistent methamphetamine-associated psychosis with methamphetamine use disorder, and cocaine use disorder in patients with co-occurring OUD are discussed in 3 patient cases.

Abstract
The endocannabinoid system (ECS) is composed of endogenous cannabinoids; components involved in their synthesis, transport, and degradation; and an expansive variety of cannabinoid receptors. Hypofunction or deregulation of the ECS is related to pathological conditions. Consequently, endogenous enhancement of endocannabinoid levels and/or regulation of their metabolism represent promising therapeutic approaches. Several major strategies have been suggested for the modulation of the ECS: (1) blocking endocannabinoids degradation, (2) inhibition of endocannabinoid cellular uptake, and (3) pharmacological modulation of cannabinoid receptors as potential therapeutic targets. Here, we focused in this review on degradation/reuptake inhibitors over cannabinoid receptor modulators in order to provide an updated synopsis of contemporary evidence advancing mechanisms of endocannabinoids as pharmacological tools with therapeutic properties for the treatment of several disorders. For this purpose, we revisited the available literature and reported the latest advances regarding the biomedical properties of fatty acid amide hydrolase and monoacylglycerol lipase inhibitors in pre-clinical and clinical studies. We also highlighted anandamide and 2-arachidonoylglycerol reuptake inhibitors with promising results in pre-clinical studies using in vitro and animal models as an outlook for future research in clinical trials.

Detecting change in psychiatric functioning in clinical trials for cocaine use disorder: sensitivity of the Addiction Severity Index and Brief Symptom Inventory. Drug Alcohol Depend 2021; 228:109070. [PMID: 34600247 PMCID: PMC8595796 DOI: 10.1016/j.drugalcdep.2021.109070] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Revised: 09/01/2021] [Accepted: 09/04/2021] [Indexed: 11/24/2022]
Abstract
BACKGROUND Assessment instruments commonly used in clinical trials to measure functional outcomes in substance users may lack sensitivity to detect change during treatment, potentially limiting findings regarding benefits of reduced drug use. This study evaluated the sensitivity of the Addiction Severity Index (ASI) to detect change in psychiatric functioning among cocaine users. METHODS Data were pooled across five clinical trials for cocaine use disorder (N = 492) that included a 12-week treatment period and 6-month follow-up. Within-person cohen's d' was used to evaluate effect size of change on the Psychiatric Composite Score of the ASI (ASI-Psych) and Global Severity Index (GSI) of the Brief Symptom Inventory, as well as cocaine use. RESULTS Effect sizes were larger for GSI than ASI-Psych from baseline to week 12 (GSI d' = 0.59; ASI-Psych d' = 0.16), and 6-month follow-up (GSI d' = 0.48; ASI-Psych d' = 0.10). For those with non-zero ASI-Psych at baseline (n = 252), medium effect sizes were found over the 12-week period (d' = 0.53) and 6-month follow-up (d' = 0.47). Effect sizes for change in days of cocaine use were most similar to GSI in either sample. CONCLUSIONS The ASI Psychiatric Composite Score may have limited sensitivity to detect change in psychiatric functioning among clinical trial participants who reduce cocaine use. It may be useful for detecting change amongst those reporting some psychiatric problems at the start of treatment. Future research should consider an instrument's sensitivity to change when assessing the potential functional benefits of reducing cocaine use.

Abstract
IMPORTANCE In the US and the United Kingdom, cocaine use is the second leading cause of illicit drug overdose death. Psychosocial treatments for cocaine use disorder are limited, and no pharmacotherapy is approved for use in the US or Europe. OBJECTIVE To compare treatments for active cocaine use among adults. DATA SOURCES PubMed and the Cochrane Database of Systematic Reviews were searched for clinical trials published between December 31, 1995, and December 31, 2017. STUDY SELECTION This meta-analysis was registered on Covidence.org (study 8731) on December 31, 2015. Clinical trials were included if they (1) had the term cocaine in the article title; (2) were published between December 31, 1995, and December 31, 2017; (3) were written in English; (4) enrolled outpatients 18 years or older with active cocaine use at baseline; and (5) reported treatment group size, treatment duration, retention rates, and urinalysis results for the presence of cocaine metabolites. A study was excluded if (1) more than 25% of participants were not active cocaine users or more than 80% of participants had negative test results for the presence of cocaine metabolites at baseline and (2) it reported only pooled urinalysis results indicating the presence of multiple substances and did not report the specific proportion of positive test results for cocaine metabolites. Multiple reviewers reached criteria consensus. Of 831 records screened, 157 studies (18.9%) met selection criteria and were included in the analysis. DATA EXTRACTION AND SYNTHESIS This study followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guideline. Search results were imported from PubMed XML into Covidence.org then Microsoft Excel. Data extraction was completed in 2 iterations to ensure fidelity. Analyses included a multilevel random-effects model, a multilevel mixed-effects meta-regression model, and sensitivity analyses. Treatments were clustered into 11 categories (psychotherapy, contingency management programs, placebo, opioids, psychostimulants, anticonvulsants, dopamine agonists, antidepressants, antipsychotics, miscellaneous medications, and other therapies). Missing data were imputed using multiple imputation by chained equations. The significance threshold for all analyses was P = .05. Data were analyzed using the metafor and mice packages in R software, version 3.3.2 (R Foundation for Statistical Computing). Data were analyzed from January 1, 2018, to February 28, 2021. MAIN OUTCOMES AND MEASURES The primary outcome was the intention-to-treat logarithm of the odds ratio (OR) of having a negative urinalysis result for the presence of cocaine metabolites at the end of each treatment period compared with baseline. The hypothesis, which was formulated after data collection, was that no treatment category would have a significant association with objective reductions in cocaine use. RESULTS A total of 157 studies comprising 402 treatment groups and 15 842 participants were included. Excluding other therapies, the largest treatment groups across all studies were psychotherapy (mean [SD] number of participants, 40.04 [36.88]) and contingency management programs (mean [SD] number of participants, 37.51 [25.51]). Only contingency management programs were significantly associated with an increased likelihood of having a negative test result for the presence of cocaine (OR, 2.13; 95% CI, 1.62-2.80), and this association remained significant in all sensitivity analyses. CONCLUSIONS AND RELEVANCE In this meta-analysis, contingency management programs were associated with reductions in cocaine use among adults. Research efforts and policies that align with this treatment modality may benefit those who actively use cocaine and attenuate societal burdens.

Abstract
BACKGROUND Stimulant (cocaine and/or methamphetamine) use has increased among people with opioid use disorder. We conducted a systematic review of medications for stimulant use disorders in this population. METHODS We searched for randomized controlled trials in multiple databases through April 2019, and dual-screened studies using pre-specified inclusion criteria. Primary outcomes were abstinence defined as stimulant-negative urine screens for ≥3 consecutive weeks; overall use as the proportion of stimulant-negative urine specimens; and retention as the proportion of participants who completed treatment. We rated strength of evidence using established criteria and conducted meta-analyses of comparable interventions and outcomes. RESULTS Thirty-four trials of 22 medications focused on cocaine use disorder in patients with opioid use disorder. Most studies enrolled participants stabilized on opioid maintenence therapy, generally methadone. None of the six studies that assessed abstinence found significant differences between groups. We found moderate-strength evidence that antidepressants (desipramine, bupropion, and fluoxetine) worsened retention. There was moderate-strength evidence that disulfiram worsened treatment retention (N = 605, RR 0.86, 95 % CI 0.77 to 0.95). We found low-strength evidence that psychostimulants (mazindol and dexamphetamine) may reduce cocaine use, though the difference was not statistically significant (standard mean difference 0.35 [95 % CI -0.05 to 0.74]). There was only 1 trial for methamphetamine use disorder, which showed insufficient-strength evidence for naltrexone. CONCLUSIONS Co-occurring stimulant/opioid use disorder is an important problem for targeting future research. Medication trials for methamphetamine use disorder are lacking in this population. Most of the medications studied for cocaine use were ineffective, although psychostimulants warrant further study.

Impact of 12 step mutual help groups on drug use disorder patients across six clinical trials. Drug Alcohol Depend 2020; 215:108213. [PMID: 32801112 PMCID: PMC7502458 DOI: 10.1016/j.drugalcdep.2020.108213] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/30/2020] [Revised: 07/17/2020] [Accepted: 07/22/2020] [Indexed: 11/23/2022]
Abstract
BACKGROUND 12 step mutual help groups are widely accessed by people with drug use disorder but infrequently subjected to rigorous evaluation. Pooling randomized trials containing a condition in which mutual help group attendance is actively facilitated presents an opportunity to assess the effectiveness of 12 step groups in large, diverse samples of drug use disorder patients. METHODS Data from six federally-funded randomized trials were pooled (n = 1730) and subjected to two-stage instrumental variables modelling, and, fixed and random effects regression models. All trials included a 12 step group facilitation condition and employed the Addiction Severity Index as a core measure. RESULTS The ability of 12 step facilitation to increase mutual help group participation among drug use disorder patients was minimal, limiting ability to employ two-stage instrumental variable models that correct for selection bias. However, traditional fixed and random effect regression models found that greater 12 step mutual help group attendance by drug use disorder patients predicted reduced use of and problems with illicit drugs and also with alcohol. CONCLUSION Facilitating significant and lasting involvement in 12 step groups may be more challenging for drug use disorder patients than for alcohol use disorder patients, which has important implications for clinical work and for effectiveness evaluations. Though selection bias could explain part of the results of traditional regression models, the finding that participation in 12 step mutual help groups predicts lower illicit drug and alcohol use and problems in a large, diverse, sample of drug use disorder patients is encouraging.

Clinical effects beyond cocaine use of sustained-release dexamphetamine for the treatment of cocaine dependent patients with comorbid opioid dependence: secondary analysis of a double-blind, placebo-controlled randomized trial. Addiction 2020; 115:917-923. [PMID: 31908066 DOI: 10.1111/add.14874] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2018] [Revised: 02/26/2019] [Accepted: 10/18/2019] [Indexed: 11/29/2022]
Abstract
BACKGROUND AND AIMS Sustained-release (SR) formulations of dexamphetamine and mixed amphetamine salts have shown positive effects in the treatment of patients with a cocaine use disorder. We previously demonstrated the efficacy of SR-dexamphetamine for patients with cocaine dependence in terms of cocaine use reductions. In this secondary analysis, we assessed whether SR-dexamphetamine treatment also improves the health status of these patients. DESIGN Multi-centre randomized, double-blind placebo-controlled trial. SETTING Four supervised heroin-assisted treatment (HAT) out-patient clinics in the Netherlands. In HAT, methadone treatment-refractory opioid-dependent patients can self-administer individually titrated doses of pharmaceutical grade diacetylmorphine, coprescribed with oral methadone. PARTICIPANTS Seventy-three cocaine-dependent patients (90% males; average age = 48.7 years), participating in HAT for their treatment-refractory comorbid opioid dependence. INTERVENTIONS Twelve weeks pharmacotherapy with once-daily, supervised intake of two tablets of SR-dexamphetamine (2 × 30 mg/day) or two identical placebo tablets. MEASUREMENTS Assessment every 4 weeks: cocaine use (time-line follow-back), physical health (Maudsley Addiction Profile-Health Symptoms Scale), mental health (Brief Symptom Inventory) and illegal activities (Addiction Severity Index). Primary outcome was 'overall health', a dichotomous, multi-domain response index based on physical health, mental health and social functioning. FINDINGS Compared with placebo, SR-dexamphetamine resulted in larger increases in the number of cocaine abstinent days (P = 0.004) and the proportion of overall health treatment responders (P = 0.045) from the 4 weeks preceding baseline to the final 4 weeks of treatment. While the number of cocaine abstinent days was not associated with overall health in the total study sample, it was positively associated with overall health among patients in poor overall health at the start of SR-dexamphetamine treatment (n = 50), i.e. patients with the potential to improve on this multi-domain response index (odds ratio = 1.076; 95% confidence interval = 1.025-1.130). CONCLUSIONS SR-dexamphetamine reduces cocaine use and may improve clinically relevant health-related outcomes in patients with cocaine dependence who are participating in heroin-assisted treatment for their comorbid heroin dependence.

Abstract
OBJECTIVE Abstinence outcomes are typically prioritized in the treatment of cocaine use disorder while ignoring patterns of low-frequency cocaine use. This study examined patterns of cocaine use frequency during treatment and evaluated how these patterns related to baseline characteristics and functioning outcomes 6 and 12 months after treatment. METHOD We used a pooled dataset (N = 720) from seven randomized clinical trials for cocaine use disorder. The Addiction Severity Index (ASI) was used to assess functioning. Repeated-measures latent class analysis was used to derive patterns of cocaine use. RESULTS Three patterns were identified: abstinence (10.6%), low-frequency use (approximately 1 day/week; 66.3%), and persistent frequent use (approximately 4 days/week; 23.1%). The low-frequency group was associated with male gender, younger age, and a criminal justice referral. The abstinent group had the highest alcohol problem severity score at baseline. At Month 6, the low-frequency group reported lower problem severity than the persistent frequent use group across multiple ASI areas, including the cocaine use as well as psychological, family, employment, and legal domains. At Month 12, the low-frequency group did not differ from the abstinent group in problem severity on any ASI domain and, relative to the persistent frequent use group, had lower cocaine use and employment problem severity. CONCLUSIONS These findings highlight the importance of adopting a harm reduction approach and recognizing the potential clinical benefits associated with nonabstinent outcomes.

Abstract
BACKGROUND Despite calls for non-abstinence endpoints in randomized clinical trials (RCTs) for cocaine use disorder, there is a lack of data validating non-abstinence endpoints. We conducted a clinical validation of reduction in cocaine frequency level as a non-abstinence endpoint in RCTs for cocaine use disorder (CUD). METHODS We utilized a pooled dataset (n = 716; 63.6 % male, 51.4 % non-Hispanic white) from seven RCTs for CUD. We specified three cocaine frequency levels at baseline and end of treatment (EOT): abstinence, low frequency (1-4 days/month), and high frequency (5+ days/month). Multiple regression analyses were conducted. RESULTS Among the sample, 38.3 % had at least a one-level reduction from baseline to EOT, whereas 61.7 % did not change/increased frequency level. At least a one-level reduction in cocaine frequency level from baseline to EOT versus no change/increase was significantly associated with better functioning up to one year following treatment on measures of cocaine use, as well as psychological, employment, legal, and other drug use problem severity domains of the Addiction Severity Index (ASI). We also conducted analyses only among those at the high frequency level at baseline and found those who reduced to low frequency use at EOT had similar outcomes at follow-up as those who reduced to abstinence. CONCLUSIONS At least a one-level reduction in cocaine frequency level from pretreatment to EOT can be a clinically meaningful endpoint given its relation to sustained clinical benefit up to one-year following treatment. These data parallel recent findings regarding reduction in drinking risk level among individuals with alcohol use disorder.

Abstract
BACKGROUND Currently, there are no accepted FDA-approved pharmacotherapies for cocaine use disorder, though numerous medications have been tested in clinical trials. We conducted a systematic review and meta-analysis to better understand the effectiveness of pharmacotherapy for cocaine use disorder. METHODS We searched multiple data sources (MEDLINE, PsycINFO, and Cochrane Library) through November 2017 for systematic reviews and randomized controlled trials (RCTs) of pharmacological interventions in adults with cocaine use disorder. When possible, we combined the findings of trials with comparable interventions and outcome measures in random-effects meta-analyses. We assessed the risk of bias of individual trials and the strength of evidence for each outcome using standardized criteria. Outcomes included continuous abstinence (3+ consecutive weeks); cocaine use; harms; and study retention. For relapse prevention studies (participants abstinent at baseline), we examined lapse (first cocaine positive or missing UDS) and relapse (two consecutive cocaine positive or missed UDS'). RESULTS Sixty-six different drugs or drug combinations were studied in seven systematic reviews and 48 RCTs that met inclusion criteria. Antidepressants were the most widely studied drug class (38 RCTs) but appear to have no effect on cocaine use or treatment retention. Increased abstinence was found with bupropion (2 RCTs: RR 1.63, 95% CI 1.02 to 2.59), topiramate (2 RCTs: RR 2.56, 95% CI 1.39 to 4.73), and psychostimulants (14 RCTs: RR 1.36, 95% CI 1.05 to 1.77), though the strength of evidence for these findings was low. We found moderate strength of evidence that antipsychotics improved treatment retention (8 RCTs: RR 1.33, 95% CI 1.03 to 1.75). DISCUSSION Most of the pharmacotherapies studied were not effective for treating cocaine use disorder. Bupropion, psychostimulants, and topiramate may improve abstinence, and antipsychotics may improve retention. Contingency management and behavioral interventions along with pharmacotherapy should continue to be explored. SR REGISTRATION Prospero CRD42018085667.

Abstract
BACKGROUND Unemployment is a chronic problem among treatment seeking substance users and is associated with poor treatment response. Most studies that have examined the relationship between employment and treatment outcomes for substance use disorders have done so by considering employment at only one specific point in time (e.g., upon entering treatment). There is a lack of research on how change in employment status over time is associated with substance use treatment outcomes. The aim of this study was to evaluate both static employment status and change in employment status over time as predictors of cocaine use treatment outcomes. METHODS We utilized data pooled from six randomized clinical trials evaluating treatment for cocaine use disorders (n = 553). Multiple general linear mixed models were conducted to determine the association of baseline, end-of-treatment, and change in employment status (from baseline to end-of-treatment) with treatment outcomes. RESULTS Treatment outcomes did not differ by baseline employment status but were significantly better for those employed versus unemployed at the end-of-treatment. In regard to change in employment status over time, those who were unemployed at baseline and acquired employment by end-of-treatment had significantly better treatment outcomes during active treatment and follow-up, as compared to those who were unemployed at baseline and remained unemployed by end-of-treatment. CONCLUSION Our findings suggest that end-of-treatment employment status may be an important marker of good outcome among those unemployed at treatment entry and support the incorporation of interventions designed to promote employment by substance use disorders treatment programs.

Abstract
BACKGROUND Spiritual/religious (S/R) interventions are commonly used to treat substance use problems, but this is the first systematic review and meta-analysis to examine their efficacy for these problems. METHODS Ten electronic databases were searched to identify eligible studies (i.e., randomized controlled trials) published between January 1990 and February 2018 that examined S/R interventions' efficacy for substance use or psycho-social-spiritual outcomes. Two reviewers independently screened studies, extracted data, and assessed risks of bias. Robust variance estimation in meta-regression was used to estimate effect sizes and conduct moderator analysis. RESULTS Twenty studies comprising 3700 participants met inclusion criteria. Four studies used inactive controls, 14 used active controls, and two used both inactive and active controls and were therefore included in estimating both absolute and relative effect sizes. The absolute effect of S/R interventions (compared with inactive controls such as no treatment) was moderate but non-significant (six studies, d = .537, 95% confidence interval [CI] = -.316, 1.390), possibly due to low power. The relative effect of S/R interventions (compared with other interventions) was statistically significant (16 studies, d = .176, 95% CI = .001, .358). Because only 12-step-oriented interventions were compared with other interventions, this finding does not apply to the relative effect of non-12-step-oriented S/R interventions. Moderator analysis showed that relative effect sizes differ significantly by country. CONCLUSION We found evidence of S/R interventions' efficacy in helping people with substance use problems. More high-quality efficacy studies of non-12-step-oriented S/R interventions for substance use problems are needed.

Abstract
BACKGROUND Most published treatment trials for cocaine use disorders (CUD) have been conducted with samples composed predominantly of White men and underrepresent women and racial/ethnic minorities. Because of the high prevalence of men and White individuals in CUD treatment trials, results from studies that have compared treatment outcomes by gender and race or ethnicity separately may not be representative of women or racial/ethnic minorities. METHODS With a sample pooled from seven randomized clinical trials of treatment for CUD (n = 629), baseline characteristics and treatment outcome responses were compared with 4 subgroups of individuals created based on the intersection of gender and race (White men, Black men, White women and Black women). RESULTS At baseline, sociodemographic status, pattern, frequency and severity of cocaine use, psychiatric comorbidities, employment and legal problems significantly differed across groups. Treatment outcome indicators collected during treatment and through follow-up, consistently indicated poorer outcomes among the sample of White women, but were similar for the other groups. CONCLUSIONS Men and women with CUD from both racial groups enter treatment with different psychosocial issues (e.g., history of violence/trauma, financial problems, co-occurring psychiatric disorders) and substance use problems (e.g. types of substances) that may impact treatment outcomes and indicate a need for culturally-informed care to deliver more effective treatment for CUD. Poorer overall outcomes among White women may reflect the need for a more focused treatment approach for this group; and highlight the importance of evaluating gender and race in treatment trials to better address health disparities.

Abstract
Taking opioids is often accompanied by the development of dependence. Unfortunately, treatment of opioid dependence is difficult, particularly because of codependence - for example, on alcohol or other drugs of abuse. In the presented study, we analyzed the potential influence of disulfiram, a drug used to aid the management of alcoholism, on opioid abstinence syndrome, which occurs as a result of opioid withdrawal. Opioid dependence in mice was induced by subcutaneous administration of either morphine or methadone at a dose of 48 mg/kg for 10 consecutive days. To trigger a withdrawal syndrome, the opioid receptor antagonist, naloxone, was administered at a dose of 1 mg/kg (subcutaneous), and the severity of withdrawal signs was assessed individually. Interruption of chronic treatment with morphine or methadone by naloxone has led to the occurrence of opioid abstinence signs such as jumping, paw tremor, wet-dog shakes, diarrhea, teeth chattering, ptosis, and piloerection. Importantly, pretreatment with disulfiram (25, 50, and 100 mg/kg) reduced the intensity of withdrawal signs induced by naloxone in morphine or methadone-treated mice. These findings show the effectiveness of disulfiram in reducing opioid abstinence signs.

Abstract
PURPOSE OF REVIEW Cocaine is a highly addictive substance with serious medical and mental health consequences. Despite these concerns, there are no Food and Drug Administration-approved medications for the treatment of cocaine use disorder (CUD). Although many medication-assisted treatments (MATs) have been investigated, no clear guidelines exist for clinicians treating patients with CUDs. RECENT FINDINGS There are a limited number of recent data examining MATs for CUD. Multiple high-quality reviews of existing literature have been performed with psychostimulants, modafinil, bupropion, topiramate and disulfiram showing the most promise. Evidence is limited by heterogeneity of studies, small sample sizes and inconsistent results. SUMMARY The current literature does not strongly support any individual MAT for CUD. Psychosocial interventions, namely contingency management, have the most evidence for treatment of CUD, but it is worth seriously considering MAT for patients who do not respond well to psychosocial interventions alone given limitations in access to care, relatively low risks associated with MAT and significant morbidity associated with CUD. Further research into MAT for CUD is necessary, as the combination of MAT and psychosocial interventions may be better than either alone.

Abstract
OBJECTIVE Abstinence outcomes are typically prioritized in the treatment of cocaine use disorder while ignoring patterns of low-frequency cocaine use. This study examined patterns of cocaine use frequency during treatment and evaluated how these patterns related to baseline characteristics and functioning outcomes 6 and 12 months after treatment. METHOD We used a pooled dataset (N = 720) from seven randomized clinical trials for cocaine use disorder. The Addiction Severity Index (ASI) was used to assess functioning. Repeated-measures latent class analysis was used to derive patterns of cocaine use. RESULTS Three patterns were identified: abstinence (10.6%), low-frequency use (approximately 1 day/week; 66.3%), and persistent frequent use (approximately 4 days/week; 23.1%). The low-frequency group was associated with male gender, younger age, and a criminal justice referral. The abstinent group had the highest alcohol problem severity score at baseline. At Month 6, the low-frequency group reported lower problem severity than the persistent frequent use group across multiple ASI areas, including the cocaine use as well as psychological, family, employment, and legal domains. At Month 12, the low-frequency group did not differ from the abstinent group in problem severity on any ASI domain and, relative to the persistent frequent use group, had lower cocaine use and employment problem severity. CONCLUSIONS These findings highlight the importance of adopting a harm reduction approach and recognizing the potential clinical benefits associated with nonabstinent outcomes.

Short and long-term improvements in psychiatric symptomatology to validate clinically meaningful treatment outcomes for cocaine use disorders. Drug Alcohol Depend 2019; 198:126-132.

Abstract
BACKGROUND Substantial efforts have been made to identify clinically meaningful non-abstinence cocaine use outcomes by establishing associations between targeted drug use outcomes and long-term functional improvements. Psychiatric symptomatology is prevalent among those seeking treatment for cocaine use disorder (CUD). Establishing an association between cocaine use outcomes and improvements in psychiatric symptomatology would support clinical validity to these outcome measures. METHOD With data pooled from 5 clinical trials evaluating treatment for CUD (n = 474) multiple linear mixed models were conducted to determine how five specific cocaine use outcome measures performed in terms of improvements in psychiatric symptomatology assessed with the Brief Symptom Inventory (BSI) at baseline, end-of-treatment and 6-month follow-up. RESULTS Three outcome measures performed comparably well (maximum days of consecutive abstinence, 3 or more weeks of abstinence and end-of-treatment abstinence), in that they consistently predicted improvements in several BSI composite scores at the end-of-treatment and follow-up. The poorer-performing outcome measures were complete abstinence during treatment, percentage of negative urinalysis results and percentage of days abstinent. Improvements in the BSI's global index of distress, positive symptom total, as well as depression, interpersonal sensitivity, obsessive-compulsion, phobic-anxiety and psychoticism dimensions were consistently associated with outcome effects, while anxiety, hostility, paranoid ideation and somatization were not. CONCLUSION The consistent short and long-term association of three outcome measures evaluated here (maximum days of consecutive abstinence, 3 or more weeks of abstinence and end-of-treatment abstinence) with improvements psychiatric symptomatology adds support to their clinical relevance as well as their adoption in trials and treatments for CUD.

Prefrontal cortex response to drug cues, craving, and current depressive symptoms are associated with treatment outcomes in methadone-maintained patients. Neuropsychopharmacology 2019; 44:826-833. [PMID: 30375498 PMCID: PMC6372589 DOI: 10.1038/s41386-018-0252-0] [Citation(s) in RCA: 27] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2018] [Revised: 10/13/2018] [Accepted: 10/17/2018] [Indexed: 12/31/2022]
Abstract
Methadone maintenance is an effective treatment for opioid use disorder, yet many methadone-maintained patients (MMPs) continue to struggle with chronic relapse. The current study evaluated whether functional near-infrared spectroscopy (fNIRS) could identify prefrontal cortex (PFC) markers of ongoing opioid use in MMPs, and whether clinical measures of depression and self-report measures of craving would also be associated with opioid use. MMPs (n = 29) underwent a drug cue reactivity paradigm during fNIRS measurements of PFC reactivity. Self-reported opioid craving (measured by a visual analog scale; 0-100) was collected before and after drug cue reactivity, and depressive symptoms were assessed via the 17-item Hamilton Depression Rating Scale (HAM-D). Hierarchical regression and partial correlations were used to evaluate associations between weekly urine drug screens over a 90-day follow-up period and fNIRS, craving, and HAM-D assessments. Neural response to drug cues in the left lateral PFC, controlling for age, sex, and days in treatment was significantly associated with percent opioid-negative urine screens during follow-up (∆F1, 24 = 13.19, p = 0.001, ∆R2 = 0.30), and correctly classified 86% of MMPs as either using opioids, or abstaining from opioids (χ2(4) = 16.28, p = 0.003). Baseline craving (p < 0.001) and HAM-D assessment (p < 0.01) were also associated with percent opioid-negative urine screens. Combining fNIRS results, baseline craving scores, and HAM-D scores created a robust predictive model (∆F3, 22 = 16.75, p < 0.001, ∆R2 = 0.59). These data provide preliminary evidence that the fNIRS technology may have value as an objective measure of treatment outcomes within outpatient methadone clinics. Depressive symptoms and drug craving were also correlated with opioid use in MMPs.

Comparative efficacy and acceptability of psychosocial interventions for individuals with cocaine and amphetamine addiction: A systematic review and network meta-analysis. PLoS Med 2018; 15:e1002715.

Abstract
BACKGROUND Clinical guidelines recommend psychosocial interventions for cocaine and/or amphetamine addiction as first-line treatment, but it is still unclear which intervention, if any, should be offered first. We aimed to estimate the comparative effectiveness of all available psychosocial interventions (alone or in combination) for the short- and long-term treatment of people with cocaine and/or amphetamine addiction. METHODS AND FINDINGS We searched published and unpublished randomised controlled trials (RCTs) comparing any structured psychosocial intervention against an active control or treatment as usual (TAU) for the treatment of cocaine and/or amphetamine addiction in adults. Primary outcome measures were efficacy (proportion of patients in abstinence, assessed by urinalysis) and acceptability (proportion of patients who dropped out due to any cause) at the end of treatment, but we also measured the acute (12 weeks) and long-term (longest duration of study follow-up) effects of the interventions and the longest duration of abstinence. Odds ratios (ORs) and standardised mean differences were estimated using pairwise and network meta-analysis with random effects. The risk of bias of the included studies was assessed with the Cochrane tool, and the strength of evidence with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. We followed the PRISMA for Network Meta-Analyses (PRISMA-NMA) guidelines, and the protocol was registered in PROSPERO (CRD 42017042900). We included 50 RCTs evaluating 12 psychosocial interventions or TAU in 6,942 participants. The strength of evidence ranged from high to very low. Compared to TAU, contingency management (CM) plus community reinforcement approach was the only intervention that increased the number of abstinent patients at the end of treatment (OR 2.84, 95% CI 1.24-6.51, P = 0.013), and also at 12 weeks (OR 7.60, 95% CI 2.03-28.37, P = 0.002) and at longest follow-up (OR 3.08, 95% CI 1.33-7.17, P = 0.008). At the end of treatment, CM plus community reinforcement approach had the highest number of statistically significant results in head-to-head comparisons, being more efficacious than cognitive behavioural therapy (CBT) (OR 2.44, 95% CI 1.02-5.88, P = 0.045), non-contingent rewards (OR 3.31, 95% CI 1.32-8.28, P = 0.010), and 12-step programme plus non-contingent rewards (OR 4.07, 95% CI 1.13-14.69, P = 0.031). CM plus community reinforcement approach was also associated with fewer dropouts than TAU, both at 12 weeks and the end of treatment (OR 3.92, P < 0.001, and 3.63, P < 0.001, respectively). At the longest follow-up, community reinforcement approach was more effective than non-contingent rewards, supportive-expressive psychodynamic therapy, TAU, and 12-step programme (OR ranging between 2.71, P = 0.026, and 4.58, P = 0.001), but the combination of community reinforcement approach with CM was superior also to CBT alone, CM alone, CM plus CBT, and 12-step programme plus non-contingent rewards (ORs between 2.50, P = 0.039, and 5.22, P < 0.001). The main limitations of our study were the quality of included studies and the lack of blinding, which may have increased the risk of performance bias. However, our analyses were based on objective outcomes, which are less likely to be biased. CONCLUSIONS To our knowledge, this network meta-analysis is the most comprehensive synthesis of data for psychosocial interventions in individuals with cocaine and/or amphetamine addiction. Our findings provide the best evidence base currently available to guide decision-making about psychosocial interventions for individuals with cocaine and/or amphetamine addiction and should inform patients, clinicians, and policy-makers.

Abstract
BACKGROUND Establishing a non-abstinence cocaine use outcome as clinically meaningful has been elusive, in part due to the lack of association between cocaine use outcomes and meaningful indicators of long-term functioning. METHODS Using data pooled across 7 clinical trials evaluating treatments for cocaine (N=718), a dichotomous indicator of functioning was created to represent a meaningful outcome ('problem-free functioning' - PFF), defined as the absence of problems across non-substance-related domains on the Addiction Severity Index. Its validity was evaluated at multiple time points (baseline, end-of-treatment, terminal follow-up) and used to explore associations with cocaine use. RESULTS The percentage of participants meeting PFF criteria increased over time (baseline=18%; end-of-treatment=32%; terminal follow-up=37%). At each time point, ANOVAs indicated those who met PFF criteria reported significantly less distress on the Brief Symptom Inventory and less perceived stress on the Perceived Stress Scale. Generalized linear models indicated categorical indices of self-reported cocaine use at the end of treatment were predictive of the probability of meeting PFF criteria during follow-up (β=-0.01, p<0.01; 95% CI: -0.008 to -0.003), with those reporting 0days or 1-4days ('occasional' use) in the final month of treatment showing an increased likelihood of achieving PFF. CONCLUSIONS Initial validation of a proxy indicator of problem-free functioning demonstrated criterion validity and sensitivity to change over time. Frequency of cocaine use in the final month of treatment was associated with PFF during follow-up, with strongest associations between PFF and abstinence or 'occasional' use.

Abstract
A growing literature exists on neural correlates of treatment outcome. However, different types-or components of-treatment have distinct theorized mechanisms of action. And it is not yet known how changes in neural activity across treatment relate to engagement in different treatment components. Participants with cocaine use disorders in a randomized clinical trial received cognitive-behavioral therapy (CBT) plus, in a 2 × 2 design, contingency management (CM) or no CM, and disulfiram or placebo. Participants performed a functional MRI Stroop task, a measure of cognitive control, at the beginning of and after the 12-week treatment. Analyses assessed changes in Stroop-related neural activity within the sample overall and assessed how changes in Stroop-related activity correlated with measures of treatment process specific to each form of treatment (i.e., participation in CBT sessions, receipt of CM prizes, administration of disulfiram pills). Within the sample overall, compared with beginning of treatment, posttreatment Stroop-related neural activity was diminished in the hippocampus, thalamus, cingulate, precentral, post- and precentral gyrus, and precuneus and culmen regions (pFWE < .05). In separate whole-brain correlation analyses, greater reductions in Stroop-related activity were associated with more treatment engagement-"CBT sessions" with the precentral gyrus, inferior parietal lobule, and middle and medial frontal gyrus; "CM prizes" with the postcentral frontal gyrus. Disulfiram "medication days" were not associated with changes in Stroop-related activity. Findings suggest that key process indicators of CBT and CM may be associated with functional changes in cognitive-control-related neurocircuitry. (PsycINFO Database Record

Abstract
Multiple randomized clinical trials (RCTs) have evaluated a range of treatments for cocaine dependence, but few of these have focused specifically on the racial diversity observed among cocaine-dependent patients. The present analyses evaluated racial variation in cocaine use and addiction-related psychosocial outcomes at baseline and follow-up among 388 African American and White adults participating in 1 of 5 RCTs evaluating a range of pharmacological and behavioral treatments for cocaine use disorders. General linear modeling (GLM) indicated significant racial variation in cocaine and psychosocial indicators at baseline. At baseline, there were significant racial differences in the number of days paid for work in the 30 days prior to the study, age, days of cocaine use in the past month, age of first cocaine use, psychosocial problems (i.e., employment, cocaine, legal, and family), public assistance status, and prevalence of lifetime anxiety disorders. There were no significant main or interaction effects of race and study on treatment outcomes at posttreatment. These findings suggest that despite significant racial differences at baseline, the pharmacological and behavioral treatments resulted in fairly comparable outcomes across racial groups in these 5 RCTs.

Abstract
OBJECTIVE To evaluate exercise as a treatment for stimulant use disorders. METHODS The STimulant Reduction Intervention using Dosed Exercise (STRIDE) study was a randomized clinical trial conducted in 9 residential addiction treatment programs across the United States from July 2010 to February 2013. Of 497 adults referred to the study, 302 met all eligibility criteria, including DSM-IV criteria for stimulant abuse and/or dependence, and were randomized to either a dosed exercise intervention (Exercise) or a health education intervention (Health Education) control, both augmenting treatment as usual and conducted thrice weekly for 12 weeks. The primary outcome of percent stimulant abstinent days during study weeks 4 to 12 was estimated using a novel algorithm adjustment incorporating self-reported Timeline Followback (TLFB) stimulant use and urine drug screen (UDS) data. RESULTS Mean percent of abstinent days based on TLFB was 90.8% (SD = 16.4%) for Exercise and 91.6% (SD = 14.7%) for Health Education participants. Percent of abstinent days using the eliminate contradiction (ELCON) algorithm was 75.6% (SD = 27.4%) for Exercise and 77.3% (SD = 25.1%) for Health Education. The primary intent-to-treat analysis, using a mixed model controlling for site and the ELCON algorithm, produced no treatment effect (P = .60). In post hoc analyses controlling for treatment adherence and baseline stimulant use, Exercise participants had a 4.8% higher abstinence rate (78.7%) compared to Health Education participants (73.9%) (P = .03, number needed to treat = 7.2). CONCLUSIONS The primary analysis indicated no significant difference between exercise and health education. Adjustment for intervention adherence showed modestly but significantly higher percent of abstinent days in the exercise group, suggesting that exercise may improve outcomes for stimulant users who have better adherence to an exercise dose.

Abstract
BACKGROUND Psychostimulant misuse is a continuously growing medical and social burden. There is no evidence proving the efficacy of pharmacotherapy. Psychosocial interventions could be a valid approach to help patients in reducing or ceasing drug consumption. OBJECTIVES To assess the effects of psychosocial interventions for psychostimulant misuse in adults. SEARCH METHODS We searched the Cochrane Drugs and Alcohol Group Specialised Register (via CRSLive); Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE; EMBASE; CINAHL; Web of Science and PsycINFO, from inception to November 2015. We also searched for ongoing and unpublished studies via ClinicalTrials.gov (www.clinicaltrials.gov) and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (apps.who.int/trialsearch/).All searches included non-English language literature. We handsearched references of topic-related systematic reviews and the included studies. SELECTION CRITERIA We included randomised controlled trials comparing any psychosocial intervention with no intervention, treatment as usual (TAU) or a different intervention in adults with psychostimulant misuse or dependence. DATA COLLECTION AND ANALYSIS We used the standard methodological procedures expected by Cochrane. MAIN RESULTS We included a total of 52 trials (6923 participants).The psychosocial interventions considered in the studies were: cognitive behavioural therapy (19 studies), contingency management (25 studies), motivational interviewing (5 studies), interpersonal therapy (3 studies), psychodynamic therapy (1 study), 12-step facilitation (4 studies).We judged most of the studies to be at unclear risk of selection bias; blinding of personnel and participants was not possible for the type of intervention, so all the studies were at high risk of performance bias with regard to subjective outcomes; the majority of studies did not specify whether the outcome assessors were blind. We did not consider it likely that the objective outcomes were influenced by lack of blinding.The comparisons made were: any psychosocial intervention versus no intervention (32 studies), any psychosocial intervention versus TAU (6 studies), and one psychosocial intervention versus an alternative psychosocial intervention (13 studies). Five of included studies did not provide any useful data for inclusion in statistical synthesis.We found that, when compared to no intervention, any psychosocial treatment: reduced the dropout rate (risk ratio (RR): 0.83, 95% confidence interval (CI) 0.76 to -0.91, 24 studies, 3393 participants, moderate quality evidence); increased continuous abstinence at the end of treatment (RR: 2.14, 95% CI 1.27 to -3.59, 8 studies, 1241 participants, low quality evidence); did not significantly increase continuous abstinence at the longest follow-up (RR: 2.12, 95% CI 0.77 to -5.86, 4 studies, 324 participants, low quality evidence); significantly increased the longest period of abstinence: (standardised mean difference (SMD): 0.48, 95% CI 0.34 to 0.63, 10 studies, 1354 participants, high quality evidence). However, it should be noted that the in the vast majority of the studies in this comparison the specific psychosocial treatment assessed in the experimental arm was given in add on to treatment as usual or to another specific psychosocial or pharmacological treatment which was received by both groups. So, many of the control groups in this comparison were not really untreated. Receiving some amount of treatment is not the same as not receiving any intervention, so we could argue that the overall effect of the experimental psychosocial treatment could be smaller if given in add on to TAU or to another intervention than if given to participants not receiving any intervention; this could translate to a smaller magnitude of the effect of the psychosocial intervention when it is given in add on.When compared to TAU, any psychosocial treatment reduced dropout rate (RR: 0.72, 95% CI 0.59 to 0.89, 6 studies, 516 participants, moderate quality evidence), did not increase continuous abstinence at the end of treatment (RR: 1.27, 95% CI 0.94 to 1.72, 2 studies, 224 participants, low quality evidence), did not increase longest period of abstinence (MD -3.15 days, 95% CI -10.35 to 4.05, 1 study, 110 participants, low quality evidence). No studies in this comparison assessed the outcome of continuous abstinence at longest follow-up.There were few studies comparing two or more psychosocial interventions, with small sample sizes and considerable heterogeneity in terms of the types of interventions assessed. None reported significant results.None of the studies reported harms related to psychosocial interventions. AUTHORS' CONCLUSIONS The addition of any psychosocial treatment to treatment as usual (usually characterised by group counselling or case management) probably reduces the dropout rate and increases the longest period of abstinence. It may increase the number of people achieving continuous abstinence at the end of treatment, although this might not be maintained at longest follow-up. The most studied and the most promising psychosocial approach to be added to treatment as usual is probably contingency management. However, the other approaches were only analysed in a few small studies, so we cannot rule out the possibility that the results were not significant because of imprecision. When compared to TAU, any psychosocial treatment may improve adherence, but it may not improve abstinence at the end of treatment or the longest period of abstinence.The majority of the studies took place in the United States, and this could limit the generalisability of the findings, because the effects of psychosocial treatments could be strongly influenced by the social context and ethnicity. The results of our review do not answer the most relevant clinical question, demonstrating which is the most effective type of psychosocial approach.Further studies should directly compare contingency management with the other psychosocial approaches.

Abstract
BACKGROUND There are very few data regarding the extent to which patients' initial expectations regarding treatment are associated with substance use treatment outcomes. OBJECTIVE This study sought to determine how patients' treatment expectations were associated with treatment outcomes. METHODS This study explored patient pre-treatment expectations and substance use treatment outcomes for 387 individuals participating in treatment for cocaine use within the United States (68.2% male, mean age 36 years old, 54.8% Caucasian). RESULTS Participants' expectations regarding abstinence were not strongly associated with post-treatment or follow-up cocaine use outcome measures. There was a significant association between the expected timeframe of receiving a positive treatment effect (i.e., outcome efficiency expectations) and days of cocaine use at the 1-month follow-up point (F = 3.45, p =.009). Post-hoc comparisons revealed that participants that expected positive effects of treatment within 0-1 week reported fewer days of cocaine use than those that expected results in 1-2 months. Also, those that expected positive effects of treatment in 1-2 months reported more cocaine use than those who expected positive results within two weeks to one month. Further, there was a significant effect of outcome efficiency expectations on a proxy measure of achieving a good treatment outcome at the three-month follow-up point (F = 11.13, p =.025). CONCLUSIONS/IMPORTANCE Results suggest that treatment outcomes are not associated with patients' treatment outcome expectations, but that some outcomes are associated with treatment outcome efficiency expectations.

Predictors of 12-Step Attendance and Participation for Individuals With Stimulant Use Disorders. J Subst Abuse Treat 2016; 68:74-82. [PMID: 27431050 DOI: 10.1016/j.jsat.2016.06.007] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2016] [Revised: 04/22/2016] [Accepted: 06/08/2016] [Indexed: 11/28/2022]
Abstract
OBJECTIVE Few studies have examined the effectiveness of 12-step peer recovery support programs with drug use disorders, especially stimulant use, and it is difficult to know how outcomes related to 12-step attendance and participation generalize to individuals with non-alcohol substance use disorders (SUDs). METHOD A clinical trial of 12-step facilitation (N=471) focusing on individuals with cocaine or methamphetamine use disorders allowed examination of four questions: Q1) To what extent do treatment-seeking stimulant users use 12-step programs and, which ones? Q2) Do factors previously found to predict 12-step participation among those with alcohol use disorders also predict participation among stimulant users? Q3) What specific baseline "12-step readiness" factors predict subsequent 12-step participation and attendance? And Q4) Does stimulant drug of choice differentially predict 12-step participation and attendance? RESULTS The four outcomes variables, attendance, speaking, duties at 12-step meetings, and other peer recovery support activities, were not related to baseline demographic or substance problem history or severity. Drug of choice was associated with differential days of Alcoholics Anonymous (AA) and Narcotics Anonymous (NA) attendance among those who reported attending, and cocaine users reported more days of attending AA or NA at 1-, 3- and 6-month follow-ups than did methamphetamine users. Pre-randomization measures of perceived benefit of 12-step groups predicted 12-step attendance at 3- and 6-month follow-ups. Pre-randomization 12-step attendance significantly predicted number of other self-help activities at end-of-treatment, 3- and 6-month follow-ups. Pre-randomization perceived benefit and problem severity both predicted number of self-help activities at end-of-treatment and 3-month follow-up. Pre-randomization perceived barriers to 12-step groups were negatively associated with self-help activities at end-of-treatment and 3-month follow-up. Whether or not one participated in any duties was predicted at all time points by pre-randomization involvement in self-help activities. CONCLUSIONS The primary finding of this study is one of continuity: prior attendance and active involvement with 12-step programs were the main signs pointing to future involvement. Limitations and recommendations are discussed.

Correlates of cocaine use during methadone treatment: implications for screening and clinical management (ANRS Methaville study). Harm Reduct J 2016; 13:12. [PMID: 27048152 PMCID: PMC4822310 DOI: 10.1186/s12954-016-0100-7] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2015] [Accepted: 03/24/2016] [Indexed: 11/11/2022] Open
Abstract
Background Cocaine use is frequent in patients receiving methadone maintenance treatment (MMT) and can jeopardize their treatment response. Identifying clinical predictors of cocaine use during methadone treatment can potentially improve clinical management. We used longitudinal data from the ANRS Methaville trial both to describe self-reported occasional and regular cocaine use during MMT and to identify clinical predictors. Methods We selected 183 patients who had data on cocaine (or crack) use at months 0 (M0), M6, and/or M12, accounting for 483 visits. The outcome was “cocaine use” in three categories: “no,” “occasional,” and “regular” use. To identify factors associated with the outcome over time, we performed a mixed multinomial logistic regression. Results Time on methadone was significantly associated with a decrease in occasional but not in regular cocaine use from 14.7 % at M0 to 7.1 % at M12, and from 10.7 % at baseline to 6.5 % at M12, respectively. After multiple adjustments, opiate injection, individuals screening positive for attention deficit hyperactivity disorder (ADHD) symptoms, and those presenting depressive symptoms were more likely to regularly use cocaine. Conclusions Although time on MMT had a positive impact on occasional cocaine use, it had no impact on regular cocaine use. Moreover, regular cocaine users were more likely to report opiate injection and to present ADHD and depressive symptoms. Early screening of these disorders and prompt tailored pharmacological and behavioral interventions can potentially reduce cocaine use and improve response to MMT. Trial registration The trial is registered with the French Agency of Pharmaceutical Products (AFSSAPS) under the number 2008-A0277-48, the European Union Drug Regulating Authorities Clinical Trials, number Eudract 2008-001338-28, the ClinicalTrials.gov Identifier: NCT00657397, and the International Standard Randomised Controlled Trial Number Register ISRCTN31125511.

Abstract
BACKGROUND AND OBJECTIVES A substantial portion of individuals entering treatment for substance use have been referred by the criminal justice system, yet there are conflicting reports regarding treatment engagement and outcome differences compared to those not referred. This study examined baseline characteristic and treatment outcome differences among cocaine-dependent individuals participating in cocaine treatment randomized trials. METHODS This secondary analysis pooled samples across five completed randomized controlled trials, resulting in 434 participants. Of these, 67 (15%) were prompted to treatment by the criminal justice system. RESULTS This subsample of criminal justice prompted (CJP) individuals did not differ from those not prompted by the criminal justice system in terms of gender, race/ethnicity, marital status, or age. However, the CJP group reported more years of regular cocaine use, more severe employment and legal problems, as well as less readiness to change prior to treatment. Treatment outcomes did not differ significantly from those without a criminal justice prompt, and on some measures the outcomes for CJP group were better (e.g., percentage of days cocaine abstinent, number of therapy sessions attended). DISCUSSION AND CONCLUSIONS These findings suggest that being prompted to treatment by the criminal justice system may not lead to poorer treatment engagement or substance use outcomes for individuals participating in randomized controlled treatment trials. SCIENTIFIC SIGNIFICANCE Despite some baseline indicators of poorer treatment prognosis, individuals who have been prompted to treatment by the criminal justice system have similar treatment outcomes as those presenting to treatment voluntarily.

Abstract
Disulfiram (DSF), a treatment for alcohol use disorders, has shown some clinical effectiveness in treating addiction to cocaine, nicotine, and pathological gambling. The mechanism of action of DSF for treating these addictions is unclear but it is unlikely to involve the inhibition of liver aldehyde dehydrogenase (ALDH2). DSF is a pro-drug and forms a number of metabolites, one of which is N-acetyl-S-(N,N-diethylcarbamoyl) cysteine (DETC-NAC). Here we describe a LCMS/MS method on a QQQ type instrument to quantify DETC-NAC in plasma and intracellular fluid from mammalian brain. An internal standard, the N,N-di-isopropylcarbamoyl homolog (MIM: 291>128) is easily separable from DETC-NAC (MIM: 263>100) on C18 RP media with a methanol gradient. The method's linear range is 0.5-500 nM from plasma and dialysate salt solution with all precisions better than 10% RSD. DETC-NAC and internal standards were recovered at better than 95% from all matrices, perchloric acid precipitation (plasma) or formic acid addition (salt) and is stable in plasma or salt at low pH for up to 24 h. Stability is observed through three freeze-thaw cycles per day for 7 days. No HPLC peak area matrix effect was greater than 10%. A human plasma sample from a prior analysis for S-(N,N-diethylcarbamoyl) glutathione (CARB) was found to have DETC NAC as well. In other human plasma samples from 62.5 mg/d and 250 mg/d dosing, CARB concentration peaks at 0.3 and 4 nM at 3 h followed by DETC-NAC peaks of 11 and 70 nM 2 h later. Employing microdialysis sampling, DETC-NAC levels in the nucleus accumbens (NAc), medial prefrontal cortex (mPFC), and plasma of rats treated with DSF reached 1.1, 2.5 and 80 nM at 6h. The correlation between the appearance and long duration of DETC-NAC concentration in rat brain and the persistence of DSF-induced changes in neurotransmitters observed by Faiman et al. (Neuropharmacology, 2013, 75C, 95-105) is discussed.

Abstract
Maintenance therapy with methadone or buprenorphine is an established and first-line treatment for opioid dependence. Clinical studies indicate that about a third of patients in opioid maintenance therapy show increased alcohol consumption and alcohol use disorders. Comorbid alcohol use disorders have been identified as a risk factor for clinical outcome and can cause poor physical and mental health, including liver disorders, noncompliance, social deterioration and increased mortality risk. The effects of opioid maintenance therapy on alcohol consumption are controversial and no clear pattern has emerged. Most studies have not found a change in alcohol use after initiation of maintenance therapy. Methadone and buprenorphine appear to carry little risk of liver toxicity, but further research on this topic is required. Recent data indicate that brief intervention strategies may help reduce alcohol intake, but the existing evidence is still limited. This review discusses further clinical implications of alcohol use disorders in opioid dependence.

Abstract
BACKGROUND Despite extensive research on gender differences in addiction, there are relatively few published reports comparing treatment outcomes for women versus men based on evidence-based treatments evaluated in randomized clinical trials. METHODS An aggregate sample comprised of data from five randomized clinical trials of treatment for cocaine dependence (N = 434) was evaluated for gender differences in clinical outcomes. Secondary analyses compared gender differences in outcome by medication condition (disulfiram versus no medication) and across multiple behavioral treatment conditions. RESULTS Women, compared with men, had poorer treatment outcomes on multiple measures of cocaine use during treatment and at post-treatment follow-up. These results appear to be primarily accounted for by disulfiram being less effective in women compared with men. There was no evidence of meaningful gender differences in outcome as a function of the behavioral therapies evaluated. CONCLUSIONS These findings suggest that women and men may benefit to similar degrees from some empirically validated behavioral treatments for addiction. Conversely, some addiction pharmacotherapies, such as disulfiram, may be associated with poorer outcomes among women relative to men and point to the need for careful assessment of pharmacological treatments in both sexes prior to widespread clinical implementation.

Abstract
INTRODUCTION Cocaine use is a global public health concern of significant magnitude, negatively impacting both the individual as well as larger society. Despite numerous trials, the discovery of an effective medication for treatment of cocaine use disorder remains elusive. AREAS COVERED This article reviews the emerging pharmacotherapies for treatment of cocaine use disorder, focusing on those medications that are currently in Phase II or III human clinical trials. Articles reviewed were obtained through searches of PubMed, Ovid MEDLINE, Clinicaltrials.gov and the Pharmaprojects database. EXPERT OPINION Research into cocaine pharmacotherapy must continue to show innovation. Given that medications targeting single neurotransmitter systems have demonstrated little efficacy in treatment of cocaine use disorder, the recent focus on pharmacotherapeutic agents with multiple neurobiochemical targets represents an exciting shift in trial design and approach. Additionally, consideration of pharmacogenetics may be helpful in identification of subpopulations of cocaine-dependent individuals who may preferentially respond to medications.

Abstract
OBJECTIVE Cocaine users often present to treatment with a multitude of problems typically considered addiction related; however, there is little evidence that reductions in cocaine use are followed by reductions in these problems. This study evaluated the relationship between rates of cocaine use during treatment and the level of non-cocaine life problems experienced during a 12-month period following treatment in a pooled sample of 434 cocaine-dependent individuals participating in 1 of 5 randomized controlled trials. METHOD Structural equation modeling and latent growth curve modeling were used to evaluate the relationship between frequency of cocaine use within treatment (8 or 12 weeks) and a latent construct of global problems indicated by the days of problems reported on the Addiction Severity Index across follow-up time points (1, 3, 6, and 12 months after treatment). RESULTS Both a continuous latent cocaine use outcome measure (percent days abstinent, percent positive urines, and maximum days of consecutive abstinence) and a dichotomous measure of cocaine use (≥21 consecutive days of abstinence) during the treatment period were associated with frequency of cocaine use and global problems during follow-up. Overall, results indicated that greater cocaine abstinence during the treatment period was associated with higher rates of abstinence and fewer global problems experienced following treatment. CONCLUSION This is one of the first studies to support a model that suggests addiction-related problems decrease in accordance with achieving abstinence from cocaine, thereby providing evidence that within-treatment cocaine abstinence has benefits that extend beyond the frequency of drug use.

Abstract
Disulfiram has shown promise as a pharmacotherapy for cocaine dependence in clinical settings, although it has many targets, and the behavioral and molecular mechanisms underlying its efficacy are unclear. One of many biochemical actions of disulfiram is inhibition of dopamine β-hydroxylase (DBH), the enzyme that converts dopamine (DA) to norepinephrine (NE) in noradrenergic neurons. Thus, disulfiram simultaneously reduces NE and elevates DA tissue levels in the brain. In rats, both disulfiram and the selective DBH inhibitor nepicastat block cocaine-primed reinstatement, a paradigm which is thought to model some aspects of drug relapse. This is consistent with some clinical results and supports the use of DBH inhibitors for the treatment of cocaine dependence. The present study was conducted to confirm and extend these results in nonhuman primates. Squirrel monkeys trained to self-administer cocaine were pretreated with disulfiram or nepicastat prior to cocaine-induced reinstatement sessions. Neither DBH inhibitor altered cocaine-induced reinstatement. Unexpectedly, nepicastat administered alone induced a modest reinstatement effect in squirrel monkeys, but not in rats. To investigate the neurochemical mechanisms underlying the behavioral results, the effects of DBH inhibition on extracellular DA were analyzed in the nucleus accumbens (NAc) using in vivo microdialysis in squirrel monkeys. Both DBH inhibitors attenuated cocaine-induced DA overflow in the NAc. Hence, the attenuation of cocaine-induced changes in accumbal DA neurochemistry was not associated with altered cocaine-seeking behavior. Overall, the reported behavioral effects of DBH inhibition in rodent models of relapse did not extend to nonhuman primates under the conditions used in the current studies.

Abstract
Treatment of psychostimulant addiction has been a major, and not fully met, challenge. For opioid addiction, there is strong evidence for the effectiveness of several medications. For psychostimulants, there is no corresponding form of agonist maintenance that has met criteria for regulatory approval or generally accepted use. Stimulant-use disorders remain prevalent and can result in both short-term and long-term adverse consequences. The mainstay of treatment remains behavioral interventions. In this paper, we discuss those interventions and some promising candidates in the search for pharmacological interventions. This article is part of the Special Issue entitled 'CNS Stimulants'.

Abstract
BACKGROUND Selection of an appropriate indictor of treatment response in clinical trials is complex, particularly for the various illicit drugs of abuse. Most widely used indicators have been selected based on expert group recommendation or convention rather than systematic empirical evaluation. Absence of an evidence-based, clinically meaningful index of treatment outcome hinders cross-study evaluations necessary for progress in addiction treatment science. METHOD Fifteen candidate indicators used in multiple clinical trials as well as some proposed recently are identified and discussed in terms of relative strengths and weaknesses (practicality, cost, verifiability, sensitivity to missing data). Using pooled data from five randomized controlled trials of cocaine dependence (N=434), the indicators were compared in terms of sensitivity to the effects of treatment and relationship to cocaine use and general functioning during follow-up. RESULTS Commonly used outcome measures (percent negative urine screens; percent days of abstinence) performed relatively well in that they were sensitive to the effects of the therapies evaluated. Others, including complete abstinence and reduction in frequency of use, were less sensitive to effects of specific therapies and were very weakly related to cocaine use or functioning during follow-up. Indicators more strongly related to cocaine use during follow-up were those that reflected achievement of sustained periods of abstinence, particularly at the end of treatment. CONCLUSIONS These analyses did not demonstrate overwhelming superiority of any single indicator, but did identify several that performed particularly poorly. Candidates for elimination included retention, complete abstinence, and indicators of reduced frequency of cocaine use.

Am J Addict 2014; 23:466-74.

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 The benefits of integrating substance abuse and psychiatric care may be limited by poor service utilization. This randomized clinical trial evaluated the efficacy of using contingency management to improve utilization of psychiatric services co-located and integrated within a community-based methadone maintenance treatment program. METHODS Opioid-dependent outpatients (n=125) with any current psychiatric disorder were randomly assigned to: (1) reinforced on-site integrated care (ROIC), with vouchers (worth $25.00) contingent on full adherence to each week of scheduled psychiatric services; or (2) standard on-site integrated care (SOIC). All participants received access to the same schedule of psychiatrist and mental health counseling sessions for 12-weeks. RESULTS ROIC participants attended more overall psychiatric sessions at month 1 (M=7.53 vs. 3.97, p<.001), month 2 (M=6.31 vs. 2.81, p<.001), and month 3 (M=5.71 vs. 2.44, p<.001). Both conditions evidenced reductions in psychiatric distress (p<.001) and similar rates of drug-positive urine samples. No differences in study retention were observed. CONCLUSIONS These findings suggest that contingency management can improve utilization of psychiatric services scheduled within an on-site and integrated treatment model. Delivering evidenced-based mental health counseling, or modifying the contingency plan to include illicit drug use, may be required to facilitate greater changes in psychiatric and substance abuse outcomes.

Abstract
The anti-alcoholism medication, disulfiram (Antabuse), decreases cocaine use in humans regardless of concurrent alcohol consumption and facilitates cocaine sensitization in rats, but the functional targets are unknown. Disulfiram inhibits dopamine β-hydroxylase (DBH), the enzyme that converts dopamine (DA) to norepinephrine (NE) in noradrenergic neurons. The goal of this study was to test the effects of chronic genetic or pharmacological DBH inhibition on behavioral responses to cocaine using DBH knockout (Dbh −/−) mice, disulfiram, and the selective DBH inhibitor, nepicastat. Locomotor activity was measured in control (Dbh +/−) and Dbh −/− mice during a 5 day regimen of saline+saline, disulfiram+saline, nepicastat+saline, saline+cocaine, disulfiram+cocaine, or nepicastat+cocaine. After a 10 day withdrawal period, all groups were administered cocaine, and locomotor activity and stereotypy were measured. Drug-naïve Dbh −/− mice were hypersensitive to cocaine-induced locomotion and resembled cocaine-sensitized Dbh +/− mice. Chronic disulfiram administration facilitated cocaine-induced locomotion in some mice and induced stereotypy in others during the development of sensitization, while cocaine-induced stereotypy was evident in all nepicastat-treated mice. Cocaine-induced stereotypy was profoundly increased in the disulfiram+cocaine, nepicastat+cocaine, and nepicastat+saline groups upon cocaine challenge after withdrawal in Dbh +/− mice. Disulfiram or nepicastat treatment had no effect on behavioral responses to cocaine in Dbh −/− mice. These results demonstrate that chronic DBH inhibition facilitates behavioral responses to cocaine, although different methods of inhibition (genetic vs. non-selective inhibitor vs. selective inhibitor) enhance qualitatively different cocaine-induced behaviors.
