Psilocybin-assisted treatment for alcohol dependence: A proof-of-concept study

Several lines of evidence suggest that classic (5HT2A agonist) hallucinogens have clinically relevant effects in alcohol and drug addiction. Although recent studies have investigated the effects of psilocybin in various populations, there have been no studies on the efficacy of psilocybin for alcohol dependence. We conducted a single-group proof-of-concept study to quantify acute effects of psilocybin in alcohol-dependent participants and to provide preliminary outcome and safety data. Ten volunteers with DSM-IV alcohol dependence received orally administered psilocybin in one or two supervised sessions in addition to Motivational Enhancement Therapy and therapy sessions devoted to preparation for and debriefing from the psilocybin sessions. Participants’ responses to psilocybin were qualitatively similar to those described in other populations. Abstinence did not increase significantly in the first 4 weeks of treatment (when participants had not yet received psilocybin), but increased significantly following psilocybin administration (p < 0.05). Gains were largely maintained at follow-up to 36 weeks. The intensity of effects in the first psilocybin session (at week 4) strongly predicted change in drinking during weeks 5–8 (r = 0.76 to r = 0.89) and also predicted decreases in craving and increases in abstinence self-efficacy during week 5. There were no significant treatment-related adverse events. These preliminary findings provide a strong rationale for controlled trials with larger samples to investigate efficacy and mechanisms.

Spiritual direction in addiction treatment: Two clinical trials

Spirituality has long been regarded as an important component of recovery from addiction. This article reports the findings of two controlled trials of spiritual direction as an adjunct in addiction treatment. In Study 1, 60 participants were randomly assigned to receive or not receive a 12-session manual-guided spiritual guidance (SG) intervention during and after inpatient treatment, in addition to treatment as usual (TAU). In Study 2, two cohorts of 40 each received TAU without or with SG during their inpatient stay. In both trials, contrary to prediction, SG had no effect on spiritual practices or substance use outcomes at any follow-up point. At the first follow-up in Study 1 only, those randomly assigned to spiritual direction unexpectedly showed significantly less improvement on depression and anxiety, relative to TAU controls. Limitations and implications for treatment are discussed.

Motivational Interviewing with Underage College Drinkers: A Preliminary Look at the Role of Empathy and Alliance

This study evaluated the impact of a motivational interview (MI) on alcohol use in underage college drinkers, and examined the specific role of empathy and alliance in MI. Fifty-five underage heavy drinkers were randomized to a one-session MI or no-treatment control. Empathy and alliance were evaluated through the MITI, participant, and therapist ratings. At two-month follow-up, multivariate tests reveal no significant interaction effects. Means comparisons indicated that both groups showed reductions in alcohol-related problems, however, only the MI sample evidenced significant reductions in binge drinking. In addition, despite the reductions of both groups, effect sizes indicated that the MI group outperformed the control in terms of binge-drinking and alcohol-related problems. Contrary to predictions, empathy and alliance showed no relationships with outcomes.

Research partnerships between academic institutions and American Indian and Alaska Native Tribes and organizations: effective strategies and lessons learned in a multisite CTN study.

Background: Community Based and Tribally Based Participatory Research (CBPR/TPR) are approaches that can be successful for developing ethical and effective research partnerships between academic institutions and Tribes and Native organizations. Objectives: The NIDA Clinical Trials Network funded a multi-site, exploratory study using CBPR/TPR to begin to better understand substance abuse issues of concern to some Tribes and Native organizations as well as strengths and resources that exist in these communities to address these concerns. Attention was paid to the development and maintenance of research partnerships in each of the sites. Methods: Each of the five partnerships is briefly described and common as well as unique challenges and successes are identified. Results: A summary of the common themes for developing these collaborative research efforts is provided. Conclusion: True, collaborative research partnerships require a great deal of time and effort in order to develop mutual trust, understanding, knowledge, and collaboration that will guide research that is rigorous as well as ethical, effective, and culturally appropriate. Scientific Significance: As AIAN communities become increasingly sophisticated partners in, and consumers of, research, CBPR and TPR are emerging as effective, ethical, culturally appropriate, and acceptable approaches. This can serve to improve the science we engage in with AIAN communities, add to the scarce literature regarding AIAN communities, and better serve AIAN communities in addressing health disparities and improving health.

Self-Efficacy as a Factor in Abstinence from Alcohol/Other Drug Abuse: A Meta-Analysis

ABSTRACT Increased self-efficacy or confidence to remain abstinent has been identified as one mechanism explaining behavior change, with investigations of this mechanism occurring most frequently in prospective mutual-help research. This study meta-analytically combined 11 studies to address critical questions about the nature and magnitude of change in self-efficacy in predicting drinking reductions among 12-step exposed individuals. Findings suggested that changes in self-efficacy were not uniform within Alcoholics Anonymous (AA) and that the magnitude of benefit associated with increased self-efficacy on outcome was not homogenous across studies. Whether this finding was the result of a measurement artifact, such as different self-efficacy measures, the nature of the samples, or the follow-up interval is not clear. Additional work is necessary to identify the nature of this mediating effect, and to uncover the extent that this effect varies by the kind and severity of substance abuse.

Sex under the influence of drugs or alcohol: common for men in substance abuse treatment and associated with high-risk sexual behavior.

Sex under the influence of drugs or alcohol is associated with high-risk sexual behavior. Heterosexual men (n = 505) in substance abuse treatment completed a computer-administered interview assessing sexual risk behaviors. Most men (73.3%) endorsed sex under the influence in the prior 90 days, and 39.1% endorsed sex under the influence during their most recent sexual event. Sex under the influence at the most recent event was more likely to involve anal intercourse, sex with a casual partner, and less condom use. Patients might benefit from interventions targeting sexual behavior and substance use as mutual triggers. (Am J Addict 2010;00:1-9).

Study design to examine the potential role of assessment reactivity in the Screening, Motivational Assessment, Referral, and Treatment in Emergency Departments (SMART-ED) protocol

BackgroundScreening, brief intervention, and referral to treatment (SBIRT) approaches to reducing hazardous alcohol and illicit drug use have been assessed in a variety of health care settings, including primary care, trauma centers, and emergency departments. A major methodological concern in these trials, however, is “assessment reactivity,” the hypothesized impact of intensive research assessments to reduce alcohol and drug use and thus mask the purported efficacy of the interventions under scrutiny. Thus, it has been recommended that prospective research designs take assessment reactivity into account. The present article describes the design of the National Institute on Drug Abuse Clinical Trials Network protocol, Screening, Motivational Assessment, Referral, and Treatment in Emergency Departments (SMART-ED), which addresses the potential bias of assessment reactivity.Methods/designThe protocol employs a 3-arm design. Following an initial brief screening, individuals identified as positive cases are consented, asked to provide demographic and locator information, and randomly assigned to one of the three conditions: minimal screening only, screening + assessment, or screening + assessment + brief intervention. In a two-stage process, the randomization procedure first reveals whether or not the participant will be in the minimal-screening-only condition. Participants in the other two groups receive a more extensive baseline assessment before it is revealed whether they have been randomized to also receive a brief intervention. Comparing the screening only and screening + assessment conditions will allow determination of the incremental effect of assessment reactivity.DiscussionAssessment reactivity is a potential source of bias that may reduce and/or lead to an underestimation of the purported effectiveness of brief interventions. From a methodological perspective, it needs to be accounted for in research designs. The SMART-ED design offers an approach to minimize assessment reactivity as a potential source of bias. Elucidating the role of assessment reactivity may offer insights into the mechanisms underlying SBIRT as well as suggest clinical options incorporating assessment reactivity as a treatment adjunct.ClinicalTrials.gov IdentifierNCT01207791.

Motivational enhancement therapy for African American substance users: a randomized clinical trial.

Limited empirical evidence concerning the efficacy of substance abuse treatments among African Americans reduces opportunities to evaluate and improve program efficacy. The current study, conducted as a secondary analysis of a randomized clinical trial conducted by the Clinical Trials Network of the National Institute of Drug Abuse, addressed this knowledge gap by examining the efficacy of motivational enhancement therapy (MET) compared with counseling as usual (CAU) among 194 African American adults seeking outpatient substance abuse treatment at 5 participating sites. The findings revealed higher retention rates among women in MET than in CAU during the initial 12 weeks of the 16-week study. Men in MET and CAU did not differ in retention. However, MET participants self-reported more drug-using days per week than participants in CAU. Implications for future substance abuse treatment research with African Americans are discussed.

Design of NIDA CTN Protocol 0047: Screening, Motivational Assessment, Referral, and Treatment in Emergency Departments (SMART-ED)

Background: 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 models have been extensively studied and are considered effective for individuals with alcohol problems presenting in EDs and other medical settings, the efficacy of such interventions has not been established for drug users presenting in EDs. Objectives: This article describes the design of a NIDA Clinical Trials Network protocol testing the efficacy of an screening, brief intervention, and referral to treatment model in medical EDs, highlighting considerations that are pertinent to the design of other studies targeting substance use behaviors in medical treatment settings. Methods: The protocol is described, and critical design decisions are discussed. Results: 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. Conclusion: 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.

American Indian methamphetamine and other drug use in the Southwestern United States.

To investigate the extent of methamphetamine and other drug use among American Indians (AIs) in the Four Corners region, we developed collaborations with Southwestern tribal entities and treatment programs in and around New Mexico. We held nine focus groups, mostly with Southwestern AI participants (N = 81) from three diverse New Mexico communities to understand community members, treatment providers, and clients/relatives views on methamphetamine. We conducted a telephone survey of staff (N = 100) from agencies across New Mexico to assess perceptions of methamphetamine use among people working with AI populations. We collected and analyzed self-reported drug use data from 300 AI clients/relatives who completed the Addiction Severity Index (ASI) in the context of treatment at three diverse addiction treatment programs. Each focus group offered a unique perspective about the effect of drugs and alcohol on each respective community. Though data from the phone surveys and ASIs suggested concerning rates of methamphetamine use, with women more adversely affected by substance use in general, alcohol was identified as the biggest substance use problem for AI populations in the Southwest. There appears to be agreement that methamphetamine use is a significant problem in these communities, but that alcohol is much more prevalent and problematic. There was less agreement about what should be done to prevent and treat methamphetamine use. Future research should attend to regional and tribal differences due to variability in drug use patterns, and should focus on identifying and improving dissemination of effective substance use interventions.
