Alcohol interventions for mandated college students: A meta-analytic review.

ABSTRACT: When college students violate campus alcohol policies, they typically receive disciplinary sanctions that include alcohol education or counseling. This meta-analysis evaluated the efficacy of these "mandated interventions" to prevent future alcohol misuse.Studies were included if they evaluated an individual- or group-level intervention, sampled students mandated to an alcohol program, used a pretest-posttest design, and assessed alcohol use as an outcome. Thirty-one studies with 68 separate interventions (N = 8,621 participants; 35% women; 85% White) were coded by independent raters with respect to sample, design, methodological features, and intervention content; the raters also calculated weighted mean effect sizes, using random-effects models. A priori predictors were examined to explain variability in effect sizes.In the 5 studies that used assessment-only control groups, mandated students reported significantly less drinking relative to controls (between-groups contrasts), d+ ranged from 0.13-0.20 for quantity and intoxication outcomes. In the 31 studies that provided within-group contrasts, significant effects were observed for all outcomes in the short-term (i.e., ? 3 months postintervention), with d+ ranging from 0.14-0.27; however, fewer significant effects appeared at longer follow-ups. Four commercially available intervention protocols (i.e., BASICS, e-CHUG, Alcohol 101, and Alcohol Skills Training Program) were associated with risk reduction.Providing mandated interventions to students who violate campus alcohol policies is an effective short-term risk reduction strategy. Continued research is needed to maintain initial gains, identify the most useful intervention components, and determine the cost-effectiveness of delivery modes. (PsycINFO Database Record

Project description:Risky alcohol consumption among college students is a significant public health issue. In the college setting, students can collaborate in the implementation of peer-led interventions. To date, evidence of peer-led programmes in reducing harmful alcohol consumption in this population is inconclusive. The aim of the current scoping review is to provide a broad overview by systematically examining and mapping the literature on peer-led interventions for preventing risky alcohol consumption by college students. The specific aims were to (1) identify the underlying focus of the interventions and assess their (2) effectiveness and (3) feasibility. A comprehensive search was conducted in PubMed, PsycINFO, CINAHL, Cochrane Library, Web of Science, DART-Europe, RCAAP, Trove and ProQuest. The inclusion criteria were peer-led interventions that exclusively addressed alcohol consumption, college students as the target population and interventional studies (randomised controlled trials, quasi-experimental studies, systematic reviews and meta-analyses of interventions). The methodological quality of the articles was evaluated. From 6654 potential studies, 13 were included. Nine interventions were described within these studies: Voice of Reason programme, Brief Advice sessions, Peer Theatre, Alcohol Education programme, Perceptions of Alcohol Norms intervention, Motivational Intervention, Alcohol Skills Training programme, Lifestyle Management Class and the Brief Alcohol Screening and Intervention for College Students. Only the last showed significant reductions in three of the four outcome measures: quantity and frequency of drinking, estimated peak blood alcohol concentration and alcohol-related consequences. It did not significantly decrease the number of heavy-drinking episodes. Peer interventions may be effective in preventing alcohol use among college students, although the evidence is weak and scarce. Further research is needed to strengthen the findings about peer-led interventions.

Project description:BackgroundAlcohol-induced blackouts, a form of anterograde amnesia that restricts the encoding of short-term memories into long-term ones, are among the most severe alcohol-related consequences. College students are at high risk of experiencing alcohol-induced blackouts, and there is a need to determine whether alcohol interventions can effectively reduce blackouts in this population. The current study uses data from 3 randomized clinical trials to examine the effect of various intervention approaches on alcohol-induced blackouts.MethodsFour interventions were compared over 3 studies: (i) a computerized feedback intervention (electronic Check-Up To Go [e-Chug]; Study 1); (ii) a single-session brief motivational intervention (BMI; Study 1); (iii) a BMI plus behavioral economic session focused on increasing substance-free activities (BMI + Substance-Free Activity Session [SFAS]; Studies 2 and 3); and (iv) a BMI plus supplemental Relaxation Training session (BMI + Relaxation Training; Studies 2 and 3). Studies 1 and 3 also included an assessment-only control condition. For each study, participants reported whether they had experienced an alcohol-induced blackout at each time point; binary logistic regressions examined differential likelihood of experiencing an alcohol-induced blackout over time.ResultsNeither the single-session BMI nor e-Chug reduced alcohol-induced blackouts over assessment only; however, participants in the BMI + SFAS or BMI + Relaxation Training condition were significantly less likely to experience an alcohol-induced blackout compared to assessment only at 1-month (Wald = 4.77, odds ratio [OR] = 0.53, p = 0.03) and 6-month follow-ups (Wald = 5.72, OR = 0.52, p = 0.02). Study 2 also revealed a larger effect for the BMI + SFAS over the BMI + Relaxation Training condition at 6 months (Wald = 4.11 OR = 0.22, p = 0.043), although this was not replicated in Study 3. The effects for the 2-session BMIs lasted 6 months, at which point maturation effects diminished differences between assessment-only and intervention conditions.ConclusionsTwo sessions of BMI are a substantial enough dose to result in reductions in alcohol-induced blackouts among college student heavy drinkers.

Project description:BACKGROUND:As mobile technology continues expanding, researchers have been using mobile phones to conduct health interventions (mobile health-mHealth-interventions). The multiple features of mobile phones offer great opportunities to disseminate large-scale, cost-efficient, and tailored messages to participants. However, the interventions to date have shown mixed results, with a large variance of effect sizes (Cohen d=-0.62 to 1.65). OBJECTIVE:The study aimed to generate cumulative knowledge that informs mHealth intervention research. The aims were twofold: (1) to calculate an overall effect magnitude for mHealth interventions compared with alternative interventions or conditions, and (2) to analyze potential moderators of mHealth interventions' comparative efficacy. METHODS:Comprehensive searches of the Communication & Mass Media Complete, PsycINFO, Web of Knowledge, Academic Search Premier, PubMed and MEDLINE databases were conducted to identify potentially eligible studies in peer-reviewed journals, conference proceedings, and dissertations and theses. Search queries were formulated using a combination of search terms: "intervention" (Title or Abstract) AND "health" (Title or Abstract) AND "*phone*" OR "black-berr*" (OR mHealth OR "application*" OR app* OR mobile OR cellular OR "short messag*" OR palm* OR iPhone* OR MP3* OR MP4* OR iPod*) (Title or Abstract). Cohen d was computed as the basic unit of analysis, and the variance-weighted analysis was implemented to compute the overall effect size under a random-effects model. Analysis of variance-like and meta-regression models were conducted to analyze categorical and continuous moderators, respectively. RESULTS:The search resulted in 3424 potential studies, the abstracts (and full text, as necessary) of which were reviewed for relevance. Studies were screened in multiple stages using explicit inclusion and exclusion criteria, and citations were evaluated for inclusion of qualified studies. A total of 64 studies were included in the current meta-analysis. Results showed that mHealth interventions are relatively more effective than comparison interventions or conditions, with a small but significant overall weighted effect size (Cohen d=0.31). In addition, the effects of interventions are moderated by theoretical paradigm, 3 engagement types (ie, changing personal environment, reinforcement tracking, social presentation), mobile use type, intervention channel, and length of follow-up. CONCLUSIONS:To the best of our knowledge, this is the most comprehensive meta-analysis to date that examined the overall effectiveness of mHealth interventions across health topics and is the first study that statistically tested moderators. Our findings not only shed light on intervention design using mobile phones, but also provide new directions for research in health communication and promotion using new media. Future research scholarship is needed to examine the effectiveness of mHealth interventions across various health issues, especially those that have not yet been investigated (eg, substance use, sexual health), engaging participants using social features on mobile phones, and designing tailored mHealth interventions for diverse subpopulations to maximize effects.
