The efficacy of motivational interviewing: A meta-analysis of controlled clinical trials (original) (raw)

Objective. The study sought to assess the effectiveness of Motivational Interviewing (MI) interventions in reducing alcohol consumption among college students, as compared to no intervention or alternative interventions. It also sought to identify the potential moderators to MI intervention effects. Data Source. Database sources consulted included Cochrane Central Register of Control Trials, PsycINFO, PsycARTICLE, PsycLIT, CINAHL, and MEDLINE. Study Inclusion and Exclusion Criteria. Included studies were (1) underpinned by experimental, quasi-experimental, and nonexperimental designs; (2) studies in which participants were either college males only or females only or both; and (3) studies in which adaptations of MI were based on key MI principles. Excluded studies were (1) non-English language studies; (2) studies not published from 2000–2012; (3) studies in which participants were not college students; (4) studies in which intervention was not delivered by face-to-face approach; an...

Motivational Interviewing is a well-known, scientifically tested method of counselling clients developed by Miller and Rollnick and viewed as a useful intervention strategy in the treatment of lifestyle problems and disease. To evaluate the effectiveness of motivational interviewing in different areas of disease and to identify factors shaping outcomes. A systematic review and meta-analysis of randomised controlled trials using motivational interviewing as the intervention. After selection criteria a systematic literature search in 16 databases produced 72 randomised controlled trials the first of which was published in 1991. A quality assessment was made with a validated scale. A meta-analysis was performed as a generic inverse variance meta-analysis. Meta-analysis showed a significant effect (95% confidence interval) for motivational interviewing for combined effect estimates for body mass index, total blood cholesterol, systolic blood pressure, blood alcohol concentration and sta...

Background—Methadone-Maintained (MM) clients who engage in excessive alcohol use are at high risk for HIV and Hepatitis B virus (HBV) infection. Nurse-led Hepatitis Health Promotion (HHP) may be one strategy to decrease alcohol use in this population. Objective—To evaluate the impact of nurse-led HHP, delivered by nurses compared to Motivational Interviewing (MI), delivered by trained therapists in group sessions or one-on-one on reduction of alcohol use. Methods—A three-arm randomized, controlled trial, conducted with 256 MM adults attending one of five MM outpatient clinics in the Los Angeles area. Within each site, moderate-to-heavy alcohol-using MM participants were randomized into one of three conditions: 1) nurse-led hepatitis health promotion group sessions (n=87); 2) MI delivered in group sessions (MI-group; n=90), or 3) MI delivered one-on-one sessions (MI-single, n=79). Results—Self-reported alcohol use was reduced from a median of 90 drinks/month at baseline to 60 drinks/month at six month follow-up. A Wilcoxon sign-rank test indicated a significant reduction in alcohol use in the total sample (p < .05). In multiple logistic regression analysis controlling for alcohol consumption at baseline and other covariates, no differences by condition were found. Discussion—As compared to two programs delivered by MI specialists, a culturally-sensitive and easy to implement nurse-led HHP program produced similar reductions in alcohol use over six months. Employing nurse-led programs may allow cost savings for treatment programs as well as a greater integration of alcohol reduction counseling along with a more comprehensive focus on general health-related issues than previously conducted.
