1.  Navigating the Tide Together: Early Collaboration between Tribal and Academic Partners in a CBPR Study 
Pimatisiwin  2013;11(3):395-409.
Community Based Participatory Research (CBPR) approaches stress the importance of building strong, cohesive collaborations between academic researchers and partnering communities; yet there is minimal research examining the actual quality of CBPR partnerships. The objective of the present paper is to describe and explore the quality of collaborative relationships across the first two years of the Healing of the Canoe project teams, comprised of researchers from the University of Washington and community partners from the Suquamish Tribe. Three quantitative/qualitative process measures were used to assess perceptions regarding collaborative processes and aspects of meeting effectiveness. Staff meetings were primarily viewed as cohesive, with clear agendas and shared communication. Collaborative processes were perceived as generally positive, with Tribal empowerment rated as especially important. Additionally, effective leadership and flexibility were highly rated while a need for a stronger community voice in decision-making was noted. Steady improvements were found in terms of trust between research teams, and both research teams reported a need for more intra-team project- and social-focused interaction. Overall, this data reveals a solid CBPR collaboration that is making effective strides in fostering a climate of respect, trust, and open communication between research partners.

2.  Drinking Outcomes Following Drink Refusal Skills Training: Differential Effects for African American and Non-Hispanic White Clients 
Determining whether a particular treatment works for specific groups of people can help tailor dissemination of evidence-based alcohol treatments. It has been proposed that individuals from different racial groups might have better outcomes in treatments that are sensitive to sociocultural issues that impact alcohol use among these groups. The current study was a secondary analysis of data from the combined behavioral intervention (CBI) condition of the COMBINE study. Those randomly assigned to CBI (n = 776) had the opportunity to receive up to 9 skills training modules, which were chosen by the therapist. The goal of the current study was to determine whether receiving 1 of the CBI modules, drink refusal and social pressure skills training, predicted differential outcomes among African American clients. Results indicated that African American clients who received the drink refusal skills training module (n = 25) had significantly fewer heavy drinking days (d = 0.79) 1 year following treatment than African Americans clients who did not receive the module (n = 35). African American clients who received the module also had significantly fewer heavy drinking days (d = 0.86) than non-Hispanic White clients who received the module (n = 241). Good clinical outcomes at 1 year post treatment were observed among 80% of African Americans who received the module, compared with 54% of African Americans who did not receive the module and 52% of non-Hispanic White clients who did receive the module. Although small sample size limits interpretation, findings provide preliminary evidence supporting the inclusion of drink refusal skills training as part of alcohol interventions for African American clients.

3.  Temporal patterns of adherence to medications and behavioral treatment and their relationship to patient characteristics and treatment response 
Addictive behaviors  2013;38(5):2119-2127.
The primary analyses of the COMBINE study revealed significant naltrexone and Combined Behavioral Intervention (CBI) main effects on drinking outcomes but failed to find additional benefits of the combination of treatments. Investigating differences in patterns of adherence over time may shed light on the treatment effects in COMBINE. The goals of the study were to identify trajectories of medication adherence and participation in CBI, to estimate predictive and moderating effects of adherence trajectories on drinking outcomes and to characterize subjects in adherence trajectories. The results of these analyses may suggest approaches to improving adherence in order to ultimately improve treatment outcome.
We used a trajectory-based approach to identify patterns of treatment adherence separately for naltrexone, acamprosate and CBI adherence. Logistic regression and general linear models assessed associations among adherence trajectories, drinking outcomes and patient characteristics.
Three trajectories of adherence were identified for each treatment: “excellent adherers”, “late non-adherers” and “early non-adherers” and there was good agreement among adherence trajectories with different treatments. “Excellent adherers” had significantly higher percent days abstinent (PDA) and lower percent heavy drinking days (PHDD). CBI significantly decreased PHDD for subjects on acamprosate in the “early non-adherers with medication” trajectory (p=0.01). Either naltrexone or acamprosate was associated with lower PHDD than placebo for “early non-adherers with CBI” (p<0.01). Receiving active medication decreased the likelihood to be in the excellent medication adherence trajectory. Younger age, greater drinking severity, dissatisfaction with the medicine and session frequency, adverse events and lack of benefit were related to less favorable medication adherence trajectories. “Excellent adherers with CBI” were significantly more satisfied with the CBI counselor.
Patterns of treatment adherence appear to be a participant characteristic. Individuals who fail to adhere early in treatment have worse outcomes regardless of treatment. However, treatment outcomes of participants who exhibit early problems with adherence to one treatment modality could potentially be improved by offering an alternative behavioral or pharmacologic treatment.

4.  Impulsivity is associated with treatment non-completion in cocaine- and methamphetamine-dependent patients but differs in nature as a function of stimulant-dependence diagnosis 
Greater impulsivity, assessed by the Barratt Impulsiveness Scale-11 (BIS-11) and Stroop interference scores, has been associated with treatment completion in cocaine-dependent patients. This study evaluated the relationships among impulsivity, stimulant-dependence diagnosis, and treatment completion. Six sites evaluating 12-step facilitation for stimulant abusers obtained the BIS-11 and Stroop from 182 methamphetamine- and/or cocaine-dependent participants. Methamphetamine-dependent, relative to cocaine-dependent, participants evidenced significantly greater BIS-11 Non-planning and Total scores. There was a trend for poorer response inhibition, measured by the Stroop, in cocaine-dependent, relative to methamphetamine-dependent, participants. Accounting for other factors related to treatment completion, BIS-11 Motor score, assessing the tendency to act without thinking, predicted treatment completion for both cocaine-dependent and methamphetamine-dependent patients. These results suggest that methamphetamine-dependent and cocaine-dependent patients may have different impulsivity profiles but that the BIS-11 may be useful in identifying both methamphetamine-dependent and cocaine-dependent patients who are at risk for treatment non-completion.

5.  Disseminating Organizational Screening and Brief Intervention Services (DO-SBIS) for Alcohol at Trauma Centers Study Design 
General hospital psychiatry  2012;35(2):174-180.
In 2005 the American College of Surgeons passed a mandate requiring that Level I trauma centers have a mechanism to identify patients who are problem drinkers and have the capacity to provide an intervention for patients who screen positive. The aim of the Disseminating Organizational Screening and Brief Intervention Services (DO-SBIS) cluster randomized trial is to test a multilevel intervention targeting the implementation of high quality alcohol screening and brief intervention (SBI) services at trauma centers.
Twenty sites selected from all US Level I trauma centers were randomized to participate in the trial. Intervention site providers receive a combination of workshop training in evidence-based motivational interviewing (MI) interventions and organizational development activities prior to conducting trauma center-based alcohol SBI with blood alcohol positive injured patients. Control sites implement care as usual. Provider MI skills, patient alcohol consumption, and organizational acceptance of SBI implementation outcomes are assessed.
The investigation has successfully recruited provider, patient, and trauma center staff samples into the study and outcomes are being followed longitudinally.
When completed, the DO-SBIS trial will inform future American College of Surgeons’ policy targeting the sustained integration of high quality alcohol SBI at trauma centers nationwide.

6.  Stimulant Abuser Groups to Engage in 12-Step (STAGE-12): A Multisite Trial in the NIDA Clinical Trials Network 
The study evaluated the effectiveness of an 8-week combined group plus individual 12-step facilitative intervention on stimulant drug use and 12-step meeting attendance and service.
Multisite randomized controlled trial, with assessments at baseline, mid-treatment, end of treatment, and 3- and 6-month post-randomization follow-ups (FU).
Intensive outpatient substance treatment programs.
Individuals with stimulant use disorders (n = 471) randomly assigned to treatment as usual (TAU) or TAU into which the STAGE-12 intervention was integrated.
Urinalysis and self-reports of substance use and 12-step attendance and activities.
Group sessions focused on increasing acceptance of 12-step principles; individual sessions incorporated an intensive referral procedure connecting participants to 12-step volunteers.
Compared to TAU, STAGE-12 participants had significantly greater odds of self-reported stimulant abstinence during the active 8-week treatment phase; however, among those who had not achieved abstinence during this period, STAGE-12 participants had more days of use. STAGE-12 participants had lower ASI Drug Composite scores at and a significant reduction from baseline to the 3-month FU, attended 12-step meetings on a greater number of days during the early phase of active treatment, engaged in more other types of 12-step activities throughout the active treatment phase and the entire FU period, and had more days of self-reported service at meetings from mid-treatment through the 6-month FU.
The present findings are mixed with respect to the impact of integrating the STAGE-12 intervention into intensive outpatient drug treatment compared to TAU on stimulant drug use. However, the results more clearly indicate that individuals in STAGE-12 had higher rates of 12-step meeting attendance and were engaged in more related activities throughout both the active treatment phase and the entire 6-month follow-up period than did those in TAU.

7.  Risk for Prescription Opioid Misuse among Patients with a History of Substance Use Disorder 
Drug and alcohol dependence  2012;127(1-3):193-199.
History of substance use disorder (SUD) is associated with risk for prescription opioid misuse in chronic pain patients; however, little data are available regarding risk for prescription opioid misuse within the subgroup of patients with SUD histories.
Participants with chronic pain, histories of SUD, and current opioid prescriptions were recruited from a single VA Medical Center. Participants (n=80) completed measures of risk for prescription opioid misuse, pain severity, pain-related interference, pain catastrophizing, attitudes about managing pain, emotional functioning, and substance abuse.
Participants were divided into three groups based on risk for prescription opioid misuse, as assessed by the Pain Medication Questionnaire (PMQ). Participants in the High-PMQ group reported more pain severity, interference, catastrophizing, depressive symptoms, and lowest self-efficacy for managing pain, relative to the Low-PMQ group; the High-PMQ group and Moderate-PMQ group differed on measures of pain severity, catastrophizing, and psychiatric symptoms (all p-values <0.05). The High-PMQ group had the highest rates of current SUD (32% versus 20% and 0, p=0.009). A regression analysis evaluated factors associated with PMQ scores: pain catastrophizing was the only variable significantly associated with risk for prescription opioid misuse.
Among patients with SUD histories, those with higher risk for prescription opioid misuse reported more pain and impairment, symptoms of depression, and were more likely to have current SUD, relative to patients with lower risk for prescription opioid misuse. In adjusted analyses, pain catastrophizing was significantly associated with risk for prescription opioid misuse, but current SUD status was not a significant predictor.

8.  Substance Use and PTSD Symptoms in Trauma Center Patients Receiving Mandated Alcohol SBI 
In an effort to integrate substance abuse treatment at trauma centers, the American College of Surgeons has mandated alcohol screening and brief intervention (SBI). Few investigations have assessed trauma center inpatients for comorbidities that may impact the effectiveness of SBI that exclusively focuses on alcohol. Randomly selected SBI eligible acute care medical inpatients (N=878) were evaluated for alcohol, illegal drugs, and symptoms consistent with a diagnosis of posttraumatic stress disorder (PTSD) using electronic medical record, toxicology, and self-report assessments; 79% of all patients had one or more alcohol, illegal drug, or PTSD symptom comorbidity. Over 70% of patients receiving alcohol SBI (n=166) demonstrated one or more illegal drug or PTSD symptom comorbidity. A majority of trauma center inpatients have comorbidities that may impact the effectiveness of mandated alcohol SBI. Investigations that realistically capture, account for, and intervene upon these common comorbid presentations are required to inform the iterative development of College policy targeting integrated substance abuse treatment at trauma centers.

9.  12-Step Interventions and Mutual Support Programs for Substance Use Disorders: An Overview 
Social work in public health  2013;28(0):313-332.
Social workers and other behavioral health professionals are likely to encounter individuals with substance use disorders in a variety of practice settings outside of specialty treatment. 12-Step mutual support programs represent readily available, no cost community-based resources for such individuals; however, practitioners are often unfamiliar with such programs. The present article provides a brief overview of 12-Step programs, the positive substance use and psychosocial outcomes associated with active 12-Step involvement, and approaches ranging from ones that can be utilized by social workers in any practice setting to those developed for specialty treatment programs to facilitate engagement in 12-Step meetings and recovery activities. The goal is to familiarize social workers with 12-Step approaches so that they are better able to make informed referrals that match clients to mutual support groups that best meet the individual’s needs and maximize the likelihood of engagement and positive outcomes.

10.  Substance Use, Treatment Admissions, and Recovery Trends in Diverse Washington State Tribal Communities 
Qualitative and quantitative data and participatory research approaches might be most valid and effective for assessing substance use/abuse and related trends in American Indian and Alaska Native (AIAN) communities.
29 federally recognized AIAN Tribes in Washington (WA) State were invited to participate in Health Directors interviews and State treatment admissions data analyses. Ten Tribal Health Directors (or designees) from across WA participated in 30–60 minute qualitative interviews. State treatment admissions data from 2002–2008 were analyzed for those who identified with one of 11 participating AIAN communities to explore admission rates by primary drug compared to non-AIANs. Those who entered treatment and belonged to one of the 11 participating tribes (n=4,851) represented 16% of admissions for those who reported a tribal affiliation.
Interviewees reported that prescription drugs, alcohol and marijuana are primary community concerns, each presenting similar and distinct challenges. Additionally, community health is tied to access to resources, services, and culturally appropriate and effective interventions. Treatment data results were consistent with interviewee reported substance use/abuse trends, with alcohol as the primary drug for 56% of AIAN adults compared to 46% of non-AIAN, and other opiates as second most common for AIAN adults in 2008 with 15% of admissions.
Findings are limited to those tribal communities/community members who agreed to participate.
Analyses suggest that some diverse AIAN communities in WA State share similar substance use/abuse, treatment, and recovery trends and continuing needs.
Scientific Significance
Appropriate and effective research with AIAN communities requires respectful and flexible approaches.

11.  Mindful Awareness in Body-oriented Therapy as an Adjunct to Women’s Substance Use Disorder Treatment: A Pilot Feasibility Study 
This study examined Mindful Awareness in Body-oriented Therapy (MABT) feasibility as a novel adjunct to women’s substance use disorder (SUD) treatment. An individual therapy, MABT combines manual and mind-body approaches to develop interoception and self-care tools for emotion regulation. A 2-group RCT repeated measures design was used, comparing MABT to treatment-as-usual (TAU) on relapse to substance use and related health outcomes. Sixty-one women were screened for eligibility and 46 enrolled. Participants randomized to MABT received 8 weekly MABT sessions. Results showed moderate to large effects, including significantly fewer days on substance use, the primary outcome, for MABT compared to TAU at post-test. Secondary outcomes showed improved eating disorder symptoms, depression, anxiety, dissociation, perceived stress, physical symptom frequency, and bodily dissociation for MABT compared to TAU at 9 month follow-up. In conclusion, it is feasible to implement MABT in women’s SUD treatment and results suggest that MABT is worthy of further efficacy testing.

12.  Drink refusal training as part of a combined behavioral intervention: Effectiveness and mechanisms of change 
Many trials have demonstrated the effectiveness of cognitive behavioral interventions for alcohol dependence, yet few studies have examined why particular treatments are effective. This study was designed to evaluate whether drink refusal training was an effective component of a combined behavioral intervention (CBI) and whether change in self-efficacy was a mechanism of change following drink refusal training for individuals with alcohol dependence.
The current study is a secondary analysis of data from the COMBINE study, a randomized clinical trial that combined pharmacotherapy with behavioral intervention in the treatment of alcohol dependence. The goal of the current study was to examine whether a drink refusal skills training module, administered as part of a 16-week CBI (n=776; 31% female, 23% non-White, average age=44) predicted changes in drinking frequency and self-efficacy during and following the CBI, and whether changes in self-efficacy following drink refusal training predicted changes in drinking frequency up to one year following treatment.
Participants (n=302) who received drink refusal skills training had significantly fewer drinking days during treatment (d=0.50) and up to one year following treatment (d=0.23). In addition the effect of the drink refusal skills training module on drinking outcomes following treatment was significantly mediated by changes in self-efficacy, even after controlling for changes in drinking outcomes during treatment (proportion mediated = 0.47).
Drink refusal training is an effective component of CBI and some of the effectiveness may be attributed to changes in client self-efficacy.

13.  Implementation and Acceptability of Mindful Awareness in Body-Oriented Therapy in Women's Substance Use Disorder Treatment 
The purpose of this study was to examine the implementation and acceptability of Mindful Awareness in Body-oriented Therapy (MABT), a novel adjunctive approach to substance use disorder (SUD) treatment. The primary aims of the study were to examine implementation of MABT as an adjunct to addiction treatment, and MABT acceptability to study participants and treatment staff.
MABT was delivered to participants randomly assigned to the intervention in a larger ongoing trial. This study focuses only on the implementation and acceptability of the intervention, as outcomes are not yet available. MABT was delivered once weekly for 8 weeks (1.5-hour sessions) and spanned inpatient and outpatient programs at a women-only treatment facility. Descriptive statistics were used to examine participant recruitment and retention to the intervention. To measure MABT acceptability, survey and written questionnaires were administered; analysis involved descriptive statistics and content analysis using Atlas.ti software.
Thirty-one (31) of the women enrolled in the study were randomized to MABT. Eighteen (18) participants completed 75%–100% of the MABT sessions. Intervention implementation required flexibility on the part of both the researchers and the clinic staff, and minor changes were made to successfully implement MABT as an adjunct to usual care. MABT was perceived to increase emotional awareness and provide new tools to cope with stress, and to positively influence SUD treatment by facilitating emotion regulation.
It was feasible to implement MABT and to recruit and retain women to MABT in women's chemical-dependency treatment. MABT acceptability and perceived benefit was high.

14.  Baseline Trajectories of Heavy Drinking and their Effects on Post-Randomization Drinking in the COMBINE Study: Empirically Derived Predictors of Drinking Outcomes During Treatment 
Alcohol (Fayetteville, N.y.)  2011;46(2):121-131.
The COMBINE Study sought to answer questions about the benefits of combining behavioral and pharmacological interventions (naltrexone and acamprosate) in alcohol-dependent patients. Our goals were to identify trajectories of heavy drinking prior to randomization in COMBINE, to characterize subjects in these trajectories, and to assess whether pre-randomization trajectories predict drinking outcomes. We analyzed daily indicators of heavy drinking in 90 days prior to randomization using a trajectory-based approach. Each subject was assigned to the most-likely pre-randomization heavy drinking trajectory, and the baseline characteristics of participants in the baseline trajectories were compared. Main and interactive effects of these trajectories and treatment factors (acamprosate, naltrexone or CBI) on summary drinking measures during active treatment (16 weeks) were assessed. We identified five trajectories of heavy drinking pre-randomization: “T1: frequent heavy drinkers”, “T2: very frequent heavy drinkers”, “T3: nearly daily heavy drinkers”, “T4: daily heavy drinkers” and “T5: daily heavy drinkers stopping early” prior to randomization. Trajectory membership was significantly associated with all drinking outcomes. Subjects in “T5: daily heavy drinkers stopping early” had comparable drinking outcomes to the subjects in “T1: frequent heavy drinkers” while the remaining trajectories were associated with significantly worse outcomes. Baseline trajectory did not interact significantly with treatment condition. These exploratory analyses confirmed the hypothesis that baseline trajectories predict post-randomization drinking outcomes. Interestingly, “T5: daily heavy drinkers stopping early” had outcomes that were comparable to the least severe baseline trajectory “T1: frequent heavy drinkers” and baseline trajectories of heavy drinking did not moderate treatment effects.

15.  A Multi-Level Approach to Predicting Community Addiction Treatment Attitudes About Contingency Management 
Adoption of contingency management (CM) by the addiction treatment community is limited to date despite much evidence for its efficacy. This study examined systemic and idiographic staff predictors of CM adoption attitudes via archival data collected from treatment organizations affiliated with the National Drug Abuse Treatment Clinical Trials Network. Multilevel modeling analyses evaluated potential predictors from organizational, treatment unit, and workforce surveys. Among these were individual and shared perceptions of staff concerning aspects of their clinic culture and climate. Modeling analyses identified three systemic predictors (clinic provision of opiate agonist services, national accreditation, lesser shared perception of workplace stress) and five idiographic predictors (staff with a graduate degree, longer service tenure, managerial position, e-communication facility, and openness to change in clinical procedures). Findings are discussed as they relate to extant literature on CM attitudes and established implementation science constructs, and their practical implications are discussed.

16.  Primary outcome indices in illicit drug dependence treatment research: systematic approach to selection and measurement of drug use end-points in clinical trials 
Addiction (Abingdon, England)  2011;107(4):694-708.
Clinical trials test the safety and efficacy of behavioral and pharmacological interventions in drug-dependent individuals. However, there is no consensus about the most appropriate outcome(s) to consider in determining treatment efficacy or on the most appropriate methods for assessing selected outcome(s). We summarize the discussion and recommendations of treatment and research experts, convened by the US National Institute on Drug Abuse, to select appropriate primary outcomes for drug dependence treatment clinical trials, and in particular the feasibility of selecting a common outcome to be included in all or most trials.
A brief history of outcomes employed in prior drug dependence treatment research, incorporating perspectives from tobacco and alcohol research, is included. The relative merits and limitations of focusing on drug-taking behavior, as measured by self-report and qualitative or quantitative biological markers, are evaluated.
Drug-taking behavior, measured ideally by a combination of self-report and biological indicators, is seen as the most appropriate proximal primary outcome in drug dependence treatment clinical trials.
We conclude that the most appropriate outcome will vary as a function of salient variables inherent in the clinical trial, such as the type of intervention, its target, treatment goals (e.g. abstinence or reduction of use) and the perspective being taken (e.g. researcher, clinical program, patient, society). It is recommended that a decision process, based on such trial variables, be developed to guide the selection of primary and secondary outcomes as well as the methods to assess them.

17.  Identifying Community Needs and Resources in a Native Community: A Research Partnership in the Pacific Northwest 
Indigenous communities have engaged in needs and resources assessments for thousands of years. By blending CBPR/TPR approaches with community-driven assets and needs assessments, academic and community based researchers can work together to better understand and identify community strengths as well as issues of concern in Native communities. This best practice approach can set research agendas that are relevant to Native communities and result in interventions and health promotion programs that are respectful of Tribal sovereignty and that incorporate unique traditions and strengths of Native communities. A successful research partnership to develop and implement a needs and resources assessment using CBPR/TPR approaches is presented using a case study that can be used as a model for other research partnerships.

18.  Validation of a Nine-Dimensional Measure of Drinking Motives for Use in Clinical Applications: The Desired Effects of Drinking Scale 
Addictive behaviors  2011;36(11):1052-1060.
The Desired Effects of Drinking (DEOD) is a 36-item, 9-subscale, self-report measure assessing reasons for drinking, concerning three general motives for alcohol use: Coping, Social, and Enhancement. These subscales include Negative Feelings, Self-esteem, Relief, Positive Feelings, Social Facilitation, Assertion, Drug Effects, Sexual Enhancement, and Mental effects. As part of the COMBINE study, scores from the nine DEOD subscales, along with additional information about alcohol consumption and consequences, were incorporated into personalized client feedback as part of a motivational enhancement intervention and as a guide for the development of a plan for treatment and change. With responses from a clinical sample of 572 individuals seeking alcohol treatment, the 9-subscale structure of the instrument was substantiated through a second-order confirmatory factor analysis, revealing moderately large to large factor loadings and good indices of model fit. A third-order factor analysis indicated these nine subscales adequately represented the three drinking motives. It is suggested these three general motives for alcohol use, which may be more distinctly delineated into the nine dimensions reflected in the DEOD structure, can be used clinically to help plan appropriate interventions and facilitate behavior change.

20.  Site selection in community-based clinical trials for substance use disorders: Strategies for effective site selection 
The importance of conducting substance use disorder treatment research in real-world settings is now well recognized. While this approach to clinical trials research offers a variety of benefits, challenges also arise. Selecting high quality sites to participate is critical to recruitment, retention, and overall trial performance when conducting multi-site, community-based clinical trials of treatments for substance use disorders.
Over the past 10 years, the NIDA-sponsored National Drug Abuse Treatment Clinical Trials Network (CTN) has strived to conduct high-quality, well-managed clinical trials. This includes developing methods for site selection to be used by investigators conducting CTN trials.
Issues relevant to site selection include the clinical trial design, availability of appropriate clinical population, and organizational attributes of potential clinical research sites. Site selection strategies include reviewing regional epidemiologic data, collecting standard site selection surveys, evaluating clinic data on existing patient populations, and site selection interviews and visits.
This paper describes considerations for selecting research sites and identifies specific strategies to employ when selecting community-based sites for participation in clinical trials.
PMCID: PMC3160724  PMID: 21854283
Medical settings such as emergency departments (EDs) present an opportunity to identify and provide services for individuals with substance use problems who might otherwise never receive any form of assessment, referral, or intervention. Although Screening, Brief Intervention, and Referral to Treatment (SBIRT) models have been extensively studied and are considered effective for individuals with alcohol problems presenting in emergency departments and other medical settings, the efficacy of such interventions has not been established for drug users presenting in EDs.
This paper describes the design of a NIDA Clinical Trials Network protocol testing the efficacy of an SBIRT model in medical EDs, highlighting considerations that that are pertinent to the design of other studies targeting substance use behaviors in medical treatment settings.
The protocol is described, and critical design decisions are discussed.
Design challenges included defining treatment conditions, study population, and site characteristics; developing the screening process; choosing the primary outcome; balancing brevity and comprehensiveness of assessment; and selecting the strategy for statistical analysis.
Many of the issues arising in the design of this study will be relevant to future studies of interventions for addictions in medical settings.
Scientific Significance
Optimal trial design is critical to determining how best to integrate substance abuse interventions into medical care.

22.  How Practice and Science Are Balanced and Blended in the NIDA Clinical Trials Network: The Bidirectional Process in the Development of the STAGE-12 Protocol as an Example 
Bidirectional, collaborative partnerships between academic researchers and practitioners have been a fundamental vehicle to achieve the National Institute on Drug Abuse (NIDA) Clinical Trials Network (CTN) goal of improving outcomes of community-based drug treatment. These partnerships blend clinical perspectives of practitioners and methodological expertise of researchers working together to address clinically meaningful issues through randomized clinical trials conducted in community treatment settings.
Bidirectionality is a guiding principle of the CTN, but its operationlization at the practical level in protocol development and implementation has not been articulated. This descriptive article presents the development of one protocol as an example and model of this bidirectional, collaborative, iterative partnership between researchers and practitioners.
This article illuminates several specific issues encountered while developing STAGE-12, a behavioral intervention to facilitate 12-step mutual support group involvement, as well as the rationale for decisions taken to resolve each.
The STAGE-12 protocol was successfully developed through a series of decisions taking into account both design factors and clinical practice needs and realities, thus maintaining a balance between methodological rigor and generalizability.
The review demonstrates the process by which research and practice have been blended in protocol development, exemplifying the underlying principle of bidirectionality, a key element in the success of the NIDA CTN.
Scientific Significance
Bidirectional partnerships as derived in the CTN, employing a hybrid model of efficacy-effectiveness research, are capable of designing and implementing protocols that are both methodologically rigorous and clinically meaningful, thus increasing likelihood of adoption and eventual improvement in public health.

25.  Self-Efficacy Change as a Mediator of Associations between Therapeutic Bond and One-Year Outcomes in Treatments for Alcohol Dependence 
Empirically-supported treatments for alcohol dependence exist, yet understanding of influences contributing to the intended behavior change is limited. The current study, a secondary analysis of the recent multi-site COMBINE trial (The COMBINE Study Research Group, 2003), tested a mediational model wherein change in client self-efficacy for abstinence was examined as a potential mediator of associations between client-report of the therapeutic bond and one-year outcomes of drinking frequency, drinking consequences, and psychiatric functioning. For analyses, the 1383 COMBINE trial participants were grouped as follows: 1) those receiving study medications (Naltrexone, Acamprosate, Naltrexone + Acamprosate, Placebo) and enrolled in medication management (MM) only (n=607), 2) those receiving study medications/MM and also enrolled in a combination behavioral intervention (CBI) as well (n=619), and 3) those enrolled in CBI only (n=157). Mediation analyses using the product-of-coefficients approach indicated self-efficacy change during treatment significantly mediated associations between the therapeutic bond with the CBI therapist and each of the three one-year outcomes among those exclusively receiving CBI, but failed to do so among those receiving pills/MM (with or without CBI). Effect sizes were small, but indicated that variance in bond-outcome associations was partially mediated by self-efficacy change for trial participants. Findings advance understanding of proximal client change processes during delivery of treatments for alcohol dependence.
