Community-based Substance Abuse Treatment Research Articles

A cluster randomized trial of an organizational linkage intervention for offenders with substance use disorders: study protocol.

BackgroundSubstance use disorders are highly prevalent in community correctional populations, yet these settings frequently are ill-equipped to identify and refer offenders to community-based treatment services. In particular, community corrections staff are often opposed to the use of medication in addiction treatment because of inadequate knowledge, resources, and organizational structures to facilitate client linkages to evidence-based services.Methods/designEach of the NIDA-funded Research Centers recruited 2 criminal justice agencies to participate in the study. Eligibility rules required study sites that were focused on community corrections (i.e., probation or parole), had few or no formal relationships with treatment providers for referring clients to medication-assisted treatment, and had no state or local policies prohibiting such relationships. Sites under the oversight of the same parent agency were eligible only if they were in geographically distinct catchment areas, and could be assigned to different study arms without cross-contamination at any level. The 18 clusters consisted of community corrections officers and their offender caseloads nested within agencies, each of which was partnered with at least one community-based substance abuse treatment program. Randomization was blocked by Research Center, within which one cluster was randomly assigned to a training-only condition (comparison) and the other to training followed by a strategic organizational linkage process (intervention). Line staff received a scientifically-grounded, systematically-delivered training session that addresses gaps in existing knowledge, perceptions, and information about medication-assisted treatment (MAT) and local availability of MAT services. Key decision-makers subsequently were asked to collaborate in a strategic planning process to enhance formal and informal linkages between criminal justice agencies and local MAT providers. It was hypothesized that the two implementation intervention components together would be more likely than staff training alone to improve the process of referring opioid- and alcohol-dependent adults under community supervision to appropriate addiction pharmacotherapy. Outcomes were measured at the client (referrals), line staff (attitudes), and organizational (linkage) levels.DiscussionThrough closer collaboration among criminal justice agencies and treatment providers, improved linkages to effective substance abuse treatment should yield significant clinical, public health and public safety benefits.Trial registrationClinical Trials gov registration number NCT01344122.

Enhancing access and retention in substance abuse treatment: The role of Medicaid payment acceptance and cultural competence

BackgroundHealth insurance coverage and quality of care are common factors believed to improve access for and retention of racial and ethnic minority groups in health care. However, there is little evidence that acceptance of public insurance and provision of culturally responsive care decrease wait time and retention of minority populations in community-based substance abuse treatment. MethodsWe analyzed client and program data collected in 2010–2011 from publicly funded treatment programs in Los Angeles County, CA. An analytical sample of 13,328 primarily African American and Latino clients nested within 104 treatment programs located in minority communities was analyzed using multilevel negative binomial regressions on count measures of days to initiate and days spent in treatment. ResultsPrograms that accepted public insurance (p<.001) and in which staff reported personal involvement (p<.01) and linkages and resources with minority communities (p<.001) were negatively associated with client wait time. Similarly, programs with culturally responsive policies and assessment and treatment practices (p<.05) were positively associated with retention in treatment, after controlling for individual and program characteristics. ConclusionsThese preliminary findings provide an evidentiary base for the role of community-based financial and cultural practices in improving accessibility and treatment adherence in a population at high risk of treatment dropout. Implications related to health care reform legislation, which seeks to expand public insurance and enhance culturally competent care, are discussed.

A Randomized Trial of a Multimodal Community-Based Prisoner Reentry Program Emphasizing Substance Abuse Treatment

Prisoner reentry programs continue to be developed and implemented to ease the process of transition into the community and to curtail fiscal pressures. This study describes and provides relapse and recidivism outcome findings related to a randomized trial evaluating a multimodal, community-based reentry program that prioritized substance abuse treatment. Results from analyses suggest negligible effects for participants of the program across multiple outcome indicators. Avenues for further exploration are provided, with a cautionary emphasis on the continued expansion of multimodal community-based reentry programs.

Lifetime Benefits and Costs of Diverting Substance-Abusing Offenders From State Prison

Prisons hold a disproportionate number of society’s drug abusers. Approximately 50% of state prisoners meet the criteria for a diagnosis of drug abuse or dependence; however, only 10% of prisoners receive drug treatment. Diverting offenders to community-based treatment has been shown to generate positive net social benefits. We build on a lifetime simulation model of a nationally representative state prison cohort to examine diversion from reincarceration to community-based substance abuse treatment. We find that diversion provides positive net societal benefits to the United States and cost savings to the national criminal justice system. Our study demonstrates the societal gains from improving access to the community drug treatment system as an alternative to prison.

The cost-effectiveness of rapid HIV testing in substance abuse treatment: Results of a randomized trial

BackgroundThe President's National HIV/AIDS Strategy calls for coupling HIV screening and prevention services with substance abuse treatment programs. Fewer than half of US community-based substance abuse treatment programs make HIV testing available on-site or through referral. MethodsWe measured the cost-effectiveness of three HIV testing strategies evaluated in a randomized trial conducted in 12 community-based substance abuse treatment programs in 2009: off-site testing referral, on-site rapid testing with information only, on-site rapid testing with risk-reduction counseling. Data from the trial included patient demographics, prior testing history, test acceptance and receipt of results, undiagnosed HIV prevalence (0.4%) and program costs. The Cost-Effectiveness of Preventing AIDS Complications (CEPAC) computer simulation model was used to project life expectancy, lifetime costs, and quality-adjusted life years (QALYs) for HIV-infected individuals. Incremental cost-effectiveness ratios (2009 US $/QALY) were calculated after adding costs of testing HIV-uninfected individuals; costs and QALYs were discounted at 3% annually. ResultsReferral for off-site testing is less efficient (dominated) compared to offering on-site testing with information only. The cost-effectiveness ratio for on-site testing with information is $60,300/QALY in the base case, or $76,300/QALY with 0.1% undiagnosed HIV prevalence. HIV risk-reduction counseling costs $36 per person more without additional benefit. ConclusionsA strategy of on-site rapid HIV testing offer with information only in substance abuse treatment programs increases life expectancy at a cost-effectiveness ratio <$100,000/QALY. Policymakers and substance abuse treatment leaders should seek funding to implement on-site rapid HIV testing in substance abuse treatment programs for those not recently tested.

The first 90 days following release from jail: Findings from the Recovery Management Checkups for Women Offenders (RMCWO) experiment

Objectives(1) To examine the impact of monthly Recovery Management Checkups (RMC) vs. control in the first 90 days post-release from jail on receipt of community-based substance abuse treatment, and (2) To explore the impact of RMC, treatment, and abstinence on HIV risk behaviors and recidivism. MethodsOf the 480 women randomized, 100% completed the intake and release interviews, and over 90% completed the 30-, 60-, and 90-day post-release interviews. Of the 915 times women assigned to RMC were interviewed (at release, 30, 69 and 90 days post release), 885 (97%) times they attended linkage meetings, 429 (47%) times they were identified as in need of substance abuse treatment, 271 (30%) times they agreed to go to treatment, 149 (16%) times they showed to the treatment intake, and 48 (5%) times they stayed in treatment at least two weeks. ResultsDuring the 90 days following release from jail, women in the RMC condition (vs. control) were significantly more likely to return to treatment sooner and to participate in substance abuse treatment. Women who received any treatment were significantly more likely than those who did not to be abstinent from any alcohol or other drugs. Those who were abstinent were significantly more likely to avoid HIV risk behaviors and recidivism. ConclusionsThese results demonstrate the feasibility of conducting monthly Recovery Management Checkups with women offenders post-release and provide support for the effectiveness of using RMC to successfully link women offenders to treatment.

Factors that Affect Treatment Expectations of Outpatients with Substance Use Problems

The study assessed treatment expectations (TE) of outpatients with substance use problems as well as factors that affect their TE. Participants were 200 outpatients presenting at three community based substance abuse treatment services. Results of general linear modelling analyses showed that outpatients with substance use problems have higher expectations about their personal contribution to the counseling process (i.e., expected to be motivated, open and responsible in counseling) and the facilitative conditions that exist in the counseling environment. In comparison, they had significantly lower expectations about clinicians’ expertise (m diff = .75 and .58, p < .001 compared to personal contribution and facilitative conditions, respectively) and clinicians’ nurturance (warmth and comfort) levels (m diff = .73 and .57, p < .001 compared to personal contribution and facilitative conditions, respectively). Females had significantly higher TE in relation to personal contribution, F(1,184) = 20.76, p < .001 and facilitative conditions, F(1,184) = 7.76, p < .01 than males. Males, individuals reporting more than one substance of concern, younger clients and individuals reporting no previous substance abuse treatment tend to underestimate level of motivation needed to contribute to counseling outcome. Individuals with extremely severe stress levels had higher clinician related expectations which include clinician expertise, genuineness, and warmth than those without such stress levels. These findings identify groups of clients that may need to be educated about specific aspects of the process of counseling early in the therapy process.

Meeting the substance abuse treatment needs of lesbian, bisexual and transgender women: implications from research to practice.

Research on the incidence, etiology and substance abuse treatment needs of lesbian, bisexual and transgender (LBT) women is limited. Most research indicates higher levels of alcohol and drug abuse among these populations compared to their heterosexual counterparts, with recent research indicating that substance abuse is a particular concern for transgender individuals and an increasing problem among younger LBT individuals. Risk factors and reasons for substance abuse among sexual minority women are similar to those of heterosexual women, yet are substantially complicated by issues of family rejection and lack of social support, stigma and minority stress, as well as abuse and harassment. Historically, substance abuse prevention, early intervention, and clinical treatment programs were designed to meet the needs of the sexual majority population with relatively few programs designed to incorporate the specific needs of sexual minorities. This article reviews findings from previous studies and utilizes new data collected from community-based and residential substance abuse treatment programs to (1) examine issues relevant to LBT women and substance use, and (2) make recommendations for tailoring substance abuse treatment programs to meet the needs of these populations.

Employing continuous quality improvement in community-based substance abuse programs.

This article aims to describe continuous quality improvement (CQI) for substance abuse prevention and treatment programs in a community-based organization setting. CQI (e.g., plan-do-study-act cycles (PDSA)) applied in healthcare and industry was adapted for substance abuse prevention and treatment programs in a community setting. The authors assessed the resources needed, acceptability and CQI feasibility for ten programs by evaluating CQI training workshops with program staff and a series of three qualitative interviews over a nine-month implementation period with program participants. The CQI activities, PDSA cycle progress, effort, enthusiasm, benefits and challenges were examined. Results indicated that CQI was feasible and acceptable for community-based substance abuse prevention and treatment programs; however, some notable resource challenges remain. Future studies should examine CQI impact on service quality and intended program outcomes. The study was conducted on a small number of programs. It did not assess CQI impact on service quality and intended program outcomes. Practical implications- This project shows that it is feasible to adapt CQI techniques and processes for community-based programs substance abuse prevention and treatment programs. These techniques may help community-based program managers to improve service quality and achieve program outcomes. This is one of the first studies to adapt traditional CQI techniques for community-based settings delivering substance abuse prevention and treatment programs.

A preliminary study of the effects of individual patient-level feedback in outpatient substance abuse treatment programs

The purpose of this study was to examine the effects of feedback provided to counselors on the outcomes of patients treated at community-based substance abuse treatment programs. A version of the Outcome Questionnaire (OQ-45), adapted to include drug and alcohol use, was administered to patients (N = 304) in 3 substance abuse treatment clinics. Phase I of the study consisted only of administration of the assessment instruments. Phase II consisted of providing feedback reports to counselors based on the adapted OQ-45 at every treatment session up to Session 12. Patients who were found to not be progressing at an expectable rate (i.e., “offtrack”) were administered a questionnaire that was used as a second feedback report for counselors. For offtrack patients, feedback compared with no feedback led to significant linear reductions in alcohol use throughout treatment and also in OQ-45 total scores and drug use from the point of the second feedback instrument to Session 12. The effect for improving mental health functioning was evident at only 1 of the 3 clinics. These results suggest that a feedback system adapted to the treatment of substance use problems is a promising approach that should be tested in a larger randomized trial.

Predictors of Retention of Women Offenders in a Community-Based Residential Substance Abuse Treatment Program

Substance abuse is a major contributing factor to women being incarcerated in the United States, and substance abuse is a critical factor in the high recidivism rates of women offenders (50–70% within one year). Understanding factors that enhance and deter women from retention in substance abuse treatment will facilitate tailored interventions to improve treatment outcomes. This prospective study examined the relationship of substance use characteristics, childhood trauma, current trauma-related symptoms, motivation to treatment, and socio-demographic characteristics, in predicting the retention of women offenders in an urban, residential substance abuse program as they re-enter the community from incarceration. All women were interviewed within the first week of admission to the residential program using the following measures: the Addiction Severity Index (ASI), the Childhood Trauma Questionnaire (CTQ), and the Trauma Symptom Inventory (TSI), and socio-demographic characteristics. Length of stay was tra...

Substance Abuse Treatment for Women who are Under Correctional Supervision in the Community: A Systematic Review of Qualitative Findings

This systematic review was conducted to more fully analyze qualitative research findings relating to community-based court-supervised substance abuse treatment for women and to make recommendations regarding treatment enhancement. Five reports of qualitative research met the inclusion criteria. Findings from these reports were extracted and analyzed using constant comparative methods. Women who are referred to court-sanctioned substance abuse treatment programs may initially be reluctant to participate. Once engaged, however, they advocate for a full complement of well-financed comprehensive services. To optimize treatment effectiveness, women recommend gender-specific programs in which ambivalence is diminished, hope is instilled, and care is individualized.

Zero-Inflated and Hurdle Models of Count Data with Extra Zeros: Examples from an HIV-Risk Reduction Intervention Trial

Background: In clinical trials of behavioral health interventions, outcome variables often take the form of counts, such as days using substances or episodes of unprotected sex. Classically, count data follow a Poisson distribution; however, in practice such data often display greater heterogeneity in the form of excess zeros (zero-inflation) or greater spread in the values (overdispersion) or both. Greater sample heterogeneity may be especially common in community-based effectiveness trials, where broad eligibility criteria are implemented to achieve a generalizable sample. Objectives: This article reviews the characteristics of Poisson model and the related models that have been developed to handle overdispersion (negative binomial (NB) model) or zero-inflation (zero-inflated Poisson (ZIP) and Poisson hurdle (PH) models) or both (zero-inflated negative binomial (ZINB) and negative binomial hurdle (NBH) models). Methods: All six models were used to model the effect of an HIV-risk reduction intervention on the count of unprotected sexual occasions (USOs), using data from a previously completed clinical trial among female patients (N = 515) participating in community-based substance abuse treatment (Tross et al. Effectiveness of HIV/AIDS sexual risk reduction groups for women in substance abuse treatment programs: Results of NIDA Clinical Trials Network Trial. J Acquir Immune Defic Syndr 2008; 48(5):581–589). Goodness of fit and the estimates of treatment effect derived from each model were compared. Results: The ZINB model provided the best fit, yielding a medium-sized effect of intervention. Conclusions and Scientific Significance: This article illustrates the consequences of applying models with different distribution assumptions on the data. If a model used does not closely fit the shape of the data distribution, the estimate of the effect of the intervention may be biased, either over- or underestimating the intervention effect.

Subgroups Analysis when Treatment and Moderators are Time-varying

Prevention scientists are often interested in understanding characteristics of participants that are predictive of treatment effects because these characteristics can be used to inform the types of individuals who benefit more or less from treatment or prevention programs. Often, effect moderation questions are examined using subgroups analysis or, equivalently, using covariate × treatment interactions in the context of regression analysis. This article focuses on conceptualizing and examining causal effect moderation in longitudinal settings in which both treatment and the putative moderators are time-varying. Studying effect moderation in the time-varying setting helps identify which individuals will benefit more or less from additional treatment services on the basis of both individual characteristics and their evolving outcomes, symptoms, severity, and need. Examining effect moderation in these longitudinal settings, however, is difficult because moderators of future treatment may themselves be affected by prior treatment (for example, future moderators may be mediators of prior treatment). This article introduces moderated intermediate causal effects in the time-varying setting, describes how they are part of Robins' Structural Nested Mean Model, discusses two problems with using a traditional regression approach to estimate these effects, and describes a new approach (a two-stage regression estimator) to estimate these effects. The methodology is illustrated using longitudinal data to examine the time-varying effects of receiving community-based substance abuse treatment as a function of time-varying severity (or need).

Program, counselor, and patient variability in the alliance: A multilevel study of the alliance in relation to substance use outcomes

We explored patient, therapist, and program variability in the alliance in relation to drug and alcohol use during treatment, and whether alliance mediates the relation of program characteristics to drug/alcohol use. Data ( N = 1,613 patients) were drawn from a randomized clinical trial investigating the efficacy of an intervention that provided alliance and outcome feedback to 112 counselors across 20 community-based outpatient substance abuse treatment clinics in the northeast United States. Program characteristics were measured using the Organization Readiness for Change scale. Using multilevel modeling, we found that alliance was related to both drug and alcohol use during the past week at the patient and program levels of analysis, but not the counselor level. Several program characteristics were related to average drug and alcohol use. The alliance was not a mediator of these relationships. Program variability in the alliance is important to the alliance–outcome relationship in the treatment of substance abuse. Better outcomes can be achieved by improving both organizational functioning and the patient–counselor alliance.

Employing policy and purchasing levers to increase the use of evidence-based practices in community-based substance abuse treatment settings: Reports from single state authorities

State public health authorities are critical to the successful implementation of science based addiction treatment practices by community-based providers. The literature to date, however, lacks examples of state level policy strategies that promote evidence-based practices (EBPs). This mixed-methods study documents changes in two critical state-to-provider strategies aimed at accelerating use of evidence-based practices: purchasing levers (financial incentives and mechanisms) and policy or regulatory levers. A sample of 51 state representatives was interviewed. Single State Authorities for substance abuse treatment (SSAs) that fund providers directly or through managed care were significantly more likely to have contracts that required or encouraged evidence-based interventions, as compared to SSAs that fund providers indirectly through sub-state entities. Policy levers included EBP-related legislation, language in rules and regulations, and evidence-based criteria in state plans and standards. These differences in state policy are likely to result in significant state level variations regarding both the extent to which EBPs are implemented by community-based treatment providers and the quality of implementation.

The Open Door Mission: Measuring and Predicting Outcomes of One Community-Based Substance Abuse Treatment Program

This study tracked graduates of a community-based substance abuse treatment program for homeless men in Houston, Texas. A standardized assessment instrument was developed to determine what characteristics were associated with a more favorable outcome. The authors found that abstinence was strongly predicted by employment, 12-Step work with Alcoholics Anonymous sponsors, and service with others in sobriety. In contrast to expectations, abstinence was not predicted by the programmatic goals of affiliation with a home church and/or identification of a mentor. Results support continued use of evidence-based outcome determinants for the Open Door Mission and other community-based substance abuse treatment programs.

Coping strategy use following computerized cognitive-behavioral therapy for substance use disorders.

Coping strategies are emerging as a predictor of treatment outcome for substance users and may be particularly important among computerized and self-change approaches. We used data from a randomized clinical trial of a computer-based version of cognitive-behavioral therapy (CBT4CBT) to: (1) examine the association between observer ratings of coping skills and self-reported coping strategies; (2) evaluate whether participants assigned to the CBT4CBT program reported greater use of coping strategies compared with those not exposed to the program; and (3) examine the differential effect of coping strategies by treatment group on drug-related outcomes. Individuals (N = 77) seeking treatment for substance dependence at a community-based outpatient substance abuse treatment facility were recruited and randomized to receive treatment-as-usual (TAU), or TAU plus CBT4CBT, with the Coping Strategies Scale administered at baseline and posttreatment. Self-reported coping strategy use was strongly correlated with observer ratings on a role-play assessment of coping skills. Although no significant group differences were found across time for coping strategy use, results suggested that as coping strategy use increased, drug use decreased, and this relationship was stronger for participants who received CBT4CBT.

Promising practices for delivery of court-supervised substance abuse treatment: Perspectives from six high-performing California counties operating Proposition 36

Operative for nearly a decade, California's voter-initiated Proposition 36 program offers many offenders community-based substance abuse treatment in lieu of likely incarceration. Research has documented program successes and plans for replication have proliferated, yet very little is known about how the Proposition 36 program works or practices for achieving optimal program outcomes. In this article, we identify policies and practices that key stakeholders perceive to be most responsible for the successful delivery of court-supervised substance abuse treatment to offenders under Proposition 36. Data was collected via focus groups conducted with 59 county stakeholders in six high-performing counties during 2009. Discussion was informed by seven empirical indicators of program performance and outcomes and was focused on identifying and describing elements contributing to success. Program success was primarily attributed to four strategies, those that: (1) fostered program engagement, monitored participant progress, and sustained cooperation among participants; (2) cultivated buy-in among key stakeholders; (3) capitalized on the role of the court and the judge; and (4) created a setting which promoted a high-quality treatment system, utilization of existing resources, and broad financial and political support for the program. Goals and practices for implementing each strategy are discussed. Findings provide a “promising practices” resource for Proposition 36 program evaluation and improvement and inform the design and study of other similar types of collaborative justice treatment efforts.
