Article: Motivational Interviewing: A Pilot Test of Active Ingredients and Mechanisms of Change.
[show abstract] [hide abstract]
ABSTRACT: Motivational interviewing (MI) is an effective treatment for substance use disorders (SUDs) that focuses on resolving ambivalence and increasing commitment to positive behavior change. Although MI has a well-developed clinical theory, research findings have been mixed in supporting its view of how change occurs. The primary aim of this pilot study was to test hypothesized MI active ingredients and mechanisms of change in reducing drinking during the initiation of a behavior change episode. Problem drinkers (N = 89) seeking treatment were randomly assigned to MI, relational MI without directive elements (spirit-only MI [SOMI]), or a self-change (SC) control condition. Participants were followed during an 8-week treatment period. The first 2 of 4 treatment sessions were videotaped and coded for fidelity, discriminability, and change talk. Overall, conditions demonstrated high fidelity. As predicted, change talk significantly increased in MI relative to the SOMI condition. Drinking was significantly reduced at end treatment, but the reduction was equivalent across conditions. Post hoc analyses found that MI reduced drinking more rapidly than SOMI and SC and that increased change talk mediated the effects of MI relative to SOMI during the week immediately following the first session. Findings are discussed in the context of the pilot nature of the study and the relative absence of experimental tests of mechanisms of behavior change in SUD treatment research.

Article: Predictors of moderated drinking in a primarily alcohol-dependent sample of men who have sex with men.
[show abstract] [hide abstract]
ABSTRACT: Understanding for whom moderated drinking is a viable, achievable, and sustainable goal among those with a range of alcohol use disorders (AUD) remains an important public health question. Despite common acceptance as severe risk factors, there is little empirical evidence to conclude whether co-occurring mental health disorders or drug dependence contribute to an individual's inability to successfully moderate his drinking. Utilizing secondary data analysis, the purpose of this study was to identify predictors of moderation among both treatment-seeking and non-treatment-seeking, primarily alcohol-dependent, problem-drinking men who have sex with men (MSM), with an emphasis on the high risk factors psychiatric comorbidity and drug dependence. Problem drinkers (N = 187) were assessed, provided feedback about their drinking, given the option to receive brief AUD treatment or change their drinking on their own, and then followed for 15 months. Findings revealed that neither psychiatric comorbidity or drug dependence predicted ability to achieve moderation when controlling for alcohol dependence severity. Those who were younger, more highly educated, and had more mild alcohol dependence were more likely to achieve moderated drinking. Impact of treatment on predictors is explored. Limitations of this study and arenas for future research are discussed.
