BACKGROUND aaa OBJECTIVE to evaluate the effectiveness of a web-based personalized normative feedback (PNF) intervention in reducing alcohol use and negative consequences among college students with different motivation levels for receiving the intervention. METHODS : Parallel-group pragmatic randomized controlled trial among college drinkers aged 18 to 30 years from all Brazilian regions. Participants were randomized to a Control (assessment only) or PNF group - 1) drinking profile; 2) normative comparisons; 3) practical costs; 4) alcohol consequences; 5) strategies to decrease risks. Outcomes were: AUDIT scores (primary outcome), the maximum number of drinks, the number of consequences, the frequency of use and number of typical drinks. Motivation for receiving the intervention was assessed with a continuous scale (range=0-10) and students were categorized either as having low motivation (score <3) or being motivated (score ≥3). Students were followed after 1, 3 and 6 months (N=4,460). Generalized mixed models assessed intervention effects via two paradigms: observed cases and attrition models (multiple imputation and pattern-mixture). RESULTS Regardless of motivation, the PNF reduced typical drinks after 1 and 3 months and maximum drinks after one month (observed and attrition models), compared to the control. When considering motivation, motivated students (N=3,552) receiving PNF reduced the typical drinks after one (b=-0.51, 95CI:-0.76;-0.27, p<0.001), three (b=-0.60, 95CI:-0.91;-0.29, p<0.001) and six months (b=-0.58, 95CI:-0.93;-0.23, p=0.001), compared to control. Attrition models showed that effects were more robust after 1 and 3 months. In contrast, students with low motivation in the PNF group increased their AUDIT score after 6 months. There were no other significant effects. CONCLUSIONS The web-based PNF for alcohol use among college students reduced only alcohol use among students, and motivation for receiving the intervention moderated the intervention effects. The intervention reduced the alcohol use only among motivated students, whereas low motivated students had an increased AUDIT score.

BACKGROUND Alcohol consumption, including binge drinking (BD) and heavy episodic drinking (HED), is one of the leading risk factors among Spanish adolescents leading to significant social, health, and economic consequences. Reduction of BD and HED in adolescents can be achieved using Web-based, computer-tailored (CT) interventions, providing highly personalized feedback that is adapted to a person’s individual characteristics and needs. Randomized controlled trials assessing the effects of tailored BD reduction programs among Spanish adolescents are scarce. OBJECTIVE The aim of this study was to test the effectiveness of the Web-based, CT intervention Alerta Alcohol, aimed at the prevention of BD in Spanish adolescents. As a secondary outcome, effects on HED, weekly consumption, and any consumption were also assessed. The adherence and process evaluation were assessed. METHODS A cluster randomized controlled trial conducted among 15 Spanish schools was developed. Each school was randomized into either an experimental condition (EC) (N=742) or a control condition (CC) (N=505). Finally, 351 participants for the EC and 261 for the CC were included in the analysis (N=612). Baseline assessment took place in January and February 2017. Demographic variables and alcohol use were assessed at baseline. Follow-up assessment of alcohol use took place 4 months later in May and June 2017. Participants were compared according to their randomization group (EC versus CC). After the baseline assessment, participants in the EC started the intervention, which consisted of short stories about BD, in which CT feedback was based on the I-Change Model for behavior change. Participants in the CC group only received the baseline questionnaire. Effects of the intervention were assessed using a three-level mixed logistic regression analysis for BD, HED, and any consumption, and a three-level mixed linear regression analysis for weekly consumption. RESULTS In total, 1247 adolescents participated in the baseline assessment and 612 participated in the follow-up assessment; the attrition rate was 50.92%. The intervention was effective in reducing HED among adolescents; the odds of HED in the CC was nine times that in the experimental condition (<i>P</i>=.04). No effects were found for BD, weekly consumption, and any consumption. Process evaluations revealed that the adolescents were satisfied with the program (68.8%), would use the program again (52.9%), and would recommend it to someone else (62.8%). Females and non-binge drinkers showed better responses in the process evaluation. CONCLUSIONS Our intervention was effective regarding HED but not regarding BD, weekly consumption, and any consumption. It may be that limiting alcohol consumption to prevent HED was easier in the Spanish context than it was to carry out further steps, such as reducing other patterns of alcohol consumption. Hence, additional actions are needed to accomplish these latter goals, including community approaches and policy actions aimed at denormalizing alcohol consumption among Spanish adolescents.
