Effectiveness of web-based personalised feedback interventions for reducing alcohol consumption among university students: A systematic review and meta-analysis.

ISSUES: Meta-analysis was conducted to examine standalone web-based personalised feedback interventions (PFI) delivered in non-structured settings for reducing university students' alcohol consumption. Subgroup analyses by gender-focus, type-of-content and accessibility were conducted. Characteristics of the sample, the intervention and study quality were examined as moderators. APPROACH: Ten databases were searched from 2000 to 2023. Eligible articles involved only randomised controlled trials. Random-effects meta-analysis was conducted to calculate the effect size on weekly alcohol consumption comparing web-PFIs and non-active controls. Meta-regressions were applied to explore effect moderators. KEY FINDINGS: Thirty-one studies were included in the narrative synthesis, 25 of which were meta-analysed. Results found significant effect size differences on weekly alcohol consumption in favour of the intervention group in the short- (SMD = 0.11, 95% confidence interval [CI] 0.06, 0.15) and long-term period (SMD = 0.09, 95% CI 0.02, 0.15). Subgroup analyses identified that interventions which were gender-specific, multicomponent and had unlimited access had higher and significant effect sizes, although they were very similar with respect to comparative groups. Moderator analyses showed that times feedback was accessed significantly contributed to the effectiveness of the intervention. Effects diminished over time, although they remained significant. IMPLICATIONS: The meta-analysis evidences the effectiveness of web-PFI for addressing university students' alcohol use, decreasing by 1.65 and 1.54 drinks consumed per week in the short- and long-term, respectively. CONCLUSIONS: The results offer empirical evidence that supports the significant, although small, effect of web-PFI delivered remotely in universities. Future research should focus on increasing their impact by introducing booster sessions and content components based on students' preferences.

Peer-led BASICS intervention to reduce alcohol consumption and alcohol-related consequences among university students: a randomized controlled trial.

Introduction: Alcohol consumption is the main substance abused during university and is associated with physical, legal, emotional, social, and cognitive consequences. The peer-led BASICS intervention has been shown to be effective in decreasing the quantity and frequency of drinking, the estimated peak blood alcohol concentration (BAC), and the number of binge drinking episodes among this population. Objective: This study evaluated the effectiveness of the peer-led BASICS intervention to reduce risky alcohol consumption among university students in the Spanish context. Materials and methods: A two-arm randomized controlled trial in a university in northern Spain including 308 first- and second-year university students recruited between October 2022 to March 2023. The intervention was a 30-min in-person peer-led motivational interview. Participants were assessed at baseline and 1-month postintervention. The primary outcome was the quantity and frequency of alcohol consumption during a typical week. The intervention effect was verified using a mixed factorial ANOVA model. Results: Compared with students in the control group, students who received the intervention reduced the number of drinks per week by 5.7 (95% CI 5.54, 5.86); the number of drinks consumed in a typical weekend by 5.2 (95% CI 5.07, 5.33); the number of drinks consumed on the occasion of greatest consumption by 4.9 (95% CI 4.78, 5.02); the number of binge drinking episodes by 1.4 (95% CI 1.37, 1.43); the peak BAC on a typical week and on the occasion of greatest consumption decreased by 0.06 (95% CI 0.058, 0.062) and 0.09 (95% CI 0.088, 0.092); the number of alcohol-related consequences by 5.8 (95% CI 5.67, 5.93); and the motivation to change their alcohol use increased by -0.8 (95% CI -0.85, -0.75). Conclusion: The peer-led BASICS intervention is effective in changing alcohol consumption and its related consequences among Spanish university students in the short term. The action of nursing students as counselors positively impacted drinking patterns among their peers.

Peer-led interventions to reduce alcohol consumption in college students: A scoping review.

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.
