From In-Session Behaviors to Drinking Outcomes: A Causal Chain for Motivational Interviewing

Client speech in favor of change within motivational interviewing sessions has been linked to treatment outcomes, but a causal chain has not yet been demonstrated. Using a sequential behavioral coding system for client speech, the authors found that, at both the session and utterance levels, specific therapist behaviors predict client change talk. Further, a direct link from change talk to drinking outcomes was observed, and support was found for a mediational role for change talk between therapist behavior and client drinking outcomes. These data provide preliminary support for the proposed causal chain indicating that client speech within treatment sessions can be influenced by therapists, who can employ this influence to improve outcomes. Selective eliciting and reinforcement of change talk is proposed as a specific active ingredient of motivational interviewing.

Does alcoholics anonymous involvement predict treatment outcome

Patients receiving inpatient treatment for alcohol dependence were followed for 31 weeks after discharge. Alcoholics Anonymous (AA) attenders, when compared with nonattenders, were not distinguishable on pretreatment patient characteristics. Posttreatment attendance of AA was not predictive of drinking outcomes. However, a measure of the degree to which patients had become involved in AA did predict more favorable outcomes.

Motivational interviewing in drug abuse services: A randomized trial.

Motivational interviewing (MI) is a directive, client-centered brief intervention to elicit behavior change by helping clients explore and resolve ambivalence. In this clinical trial, 152 outpatients and 56 inpatients entering public agencies for treatment of drug problems were randomly assigned to receive or not receive a single session of manual-guided MI. Drug use was assessed by self-report, urine toxicology, and collateral reports from significant others at baseline, 3, 6, 9, and 12 months. Contrary to prior reports, MI showed no effect on drug use outcomes when added to inpatient or outpatient treatment, although both groups showed substantial increases in abstinence from illicit drugs and alcohol.

A randomized trial of two methods for engaging treatment-refusing drug users through concerned significant others.

In a randomized clinical trial, 90 concerned significant others (CSOs) of treatment-refusing illicit drug users were assigned to either (a) community reinforcement and family training (CRAFT), which teaches behavior change skills, (b) CRAFT with additional group aftercare sessions after the completion of the individual sessions; or (c) Al-Anon and Nar-Anon facilitation therapy (Al-Nar FT). All protocols received 12 hr of manual-guided individual treatment. Follow-up rates for the CSOs were consistently at least 96%. The CRAFT conditions were significantly more effective than Al-Nar FT in engaging initially unmotivated drug users into treatment. CRAFT alone engaged 58.6%, CRAFT + aftercare engaged 76.7%, and Al-Nar FT engaged 29.0%. No CSO engaged a treatment-refusing loved one once individual sessions had been completed.

Community reinforcement and family training (CRAFT): engaging unmotivated drug users in treatment.

Although motivation for drug abuse treatment is a substantial problem, unilateral intervention through concerned significant others (CSOs) represents a promising method for engaging unmotivated individuals. The Community Reinforcement and Family Training (CRAFT) program, based on principles of reinforcement was developed for this specific purpose. In Phase I, CSOs received the CRAFT intervention, whereby they were taught skills for modifying a loved ones drug-using behavior and for enhancing treatment engagement. CSOs were evaluated at 3 and 6 months. In Phase II, engaged drug users received treatment using the Community Reinforcement Approach (CRA). A total of 62 CSOs participated in this evaluation of the effectiveness of CRAFT. CSOs completed, on average, 87% of offered treatment sessions. During the 6-month study period, 74% succeeded in engaging their resistant loved one in treatment. Reported abstinence both from illicit drugs and alcohol increased significantly for drug users engaged in treatment, but not for unengaged cases. All CSOs showed significant reduction in depression, anxiety, anger, and physical symptoms, with average scores dropping into the normal range on all measures. CRAFT provides a promising alternative to confrontational and detachment approaches in counseling CSOs to help their loved ones.

The inventory of drug use consequences (InDUC): test-retest stability and sensitivity to detect change.

The Inventory of Drug Use Consequences (InDUC) is a self-administered measure of consequences of drug use. Psychometric characteristics have been published for its alcohol-focused parent instrument (Drinker Inventory of Consequences; W. Miller, J. Tonigan, & R. Longabough, 1995). Two studies provided information about the test-retest reliability (lifetime) of InDUC scales (Study 1, N = 34) and the replicability of findings to the 5 InDUC scales (recent; Study 2, N = 208). Four scales had good to excellent test-retest reliability. Findings also indicate that reductions in drug use and problems after treatment are large and that the magnitude of change differs between drug use and consequences. Consequences of drug use should be measured directly rather than be inferred from measures of use.

Cognitive impairment influences drinking outcome by altering therapeutic mechanisms of change.

Serious neuropsychological impairments are seen in a minority of addiction treatment clients, and, theoretically, these impairments should undermine behavioral changes targeted by treatment; however, little evidence supports a direct influence of impairment on treatment response. To address this paradox, the authors used structural equation modeling and Project MATCH data (N=1,726) to examine direct, mediated, and moderated paths between cognitive impairment, therapeutic processes, and treatment outcome. Mediated relations were found, wherein impairment led to less treatment compliance, lower self-efficacy, and greater Alcoholics Anonymous Involvement, which, in turn, more proximally predicted drinking. Impairment further moderated the effect of self-efficacy, making it a poor predictor of drinking outcomes in impaired clients, thereby suggesting that impaired and unimpaired clients traverse different pathways to addiction recovery.

Active ingredients: how and why evidence-based alcohol behavioral treatment interventions work.

This article summarizes the proceedings of a symposium that was organized and chaired by Richard Longabaugh and presented at the 2004 Research Society on Alcoholism meeting in Vancouver, British Columbia, Canada. The aim of the presentation was to focus on evidence for the active ingredients of behavioral therapies for patients with alcohol use disorders. Dennis M. Donovan, PhD, reviewed evidence for the active ingredients of cognitive behavioral therapy. Barbara S. McCrady, PhD, presented a conceptual model for mechanisms of change in alcohol behavior couples therapy and reviewed evidence for this model. J. Scott Tonigan, PhD, presented data testing three hypothesized mechanisms of change in twelve-step facilitation treatment. Mitchell P. Karno, PhD, presented therapy process data that tested whether matching therapist behaviors to client attribute across three therapies affected drinking outcomes. Jon Morgenstern served as discussant.

Reliability of form 90D: An instrument for quantifying drug use

Clients just entering treatment for nonalcohol primary drug use were asked to report on their frequency of drug use at two times 2 days apart. Test-retest correlations for the lifetime use of drugs were fair to excellent, and those for drug use in the last 90 days, although variable, were generally very good. For lifetime use, correlations were highest for opiates and stimulants and lowest for inhalants, whereas for the recent period correlations were highest for opiates and lowest for stimulants. Correlations were uniformly high for measures of general life functioning. Initial validity assessments with urine drug screen results as criterion were good, with no false negative errors in four of six drug use categories. Overall Form 90D appears to be a reasonably reliable and valid interview instrument for measuring drug use occurrence and frequency for both lifetime and recent use. Care is warranted in assessing classes of drugs that are used less frequently.

Adolescent Substance Abuse: The Effects of Alcohol and Marijuana on Neuropsychological Performance

BACKGROUND Adolescence is a period in which cognition and brain undergo dramatic parallel development. Whereas chronic use of alcohol and marijuana is known to cause cognitive impairments in adults, far less is known about the effect of these substances of abuse on adolescent cognition, including possible interactions with developmental processes. METHODS Neuropsychological performance, alcohol use, and marijuana use were assessed in 48 adolescents (ages 12 to 18), recruited in 3 groups: a healthy control group (HC, n = 15), a group diagnosed with substance abuse or dependence (SUD, n = 19), and a group with a family history positive for alcohol use disorder (AUD) but no personal substance use disorder (FHP, n = 14). Age, drinks per drinking day (DPDD), percentage days drinking, and percentage days using marijuana were considered as covariates in a MANCOVA in which 6 neuropsychological composites (Verbal Reasoning, Visuospatial Ability, Executive Function, Memory, Attention, and Processing Speed) served as dependent variables. RESULTS More DPDD predicted poorer performance on Attention and Executive Function composites, and more frequent use of marijuana was associated with poorer Memory performance. In separate analyses, adolescents in the SUD group had lower scores on Attention, Memory, and Processing Speed composites, and FHP adolescents had poorer Visuospatial Ability. CONCLUSIONS In combination, these analyses suggest that heavy alcohol use in adolescence leads to reduction in attention and executive functioning and that marijuana use exerts an independent deleterious effect on memory. At the same time, premorbid deficits associated with family history of AUD appeared to be specific to visuospatial ability.
