A cluster-randomized controlled trial (CRCT) is carried out in students aged 14-19 enrolled in 24 high schools from Andalusia (Spain), which are randomized either to experimental (EC-1, EC-2) or waiting-list control conditions (CC). EC-1 receives an online intervention (Alerta Alcohol) with personalized health advice, using textual feedback and several gamification techniques. EC-2 receives an improved version (Alerta Alcohol 2.0) using animated videos and new gamification strategies. Both programs consist of nine sessions (seven taking place at high school and two at home): session 1 or baseline, sessions 2 and 3 that provide tailored advice based on the I-Change Model; sessions 4, 5, 7, and 8 are booster sessions, and sessions 6 and 9 are follow-up questionnaires at six and twelve months. The CC completes the baseline and the evaluation questionnaires. The primary outcome is BD within 30 days before post-test evaluations, and as secondary outcomes we assess other patterns of alcohol use. The findings should help the development of future alcohol drinking prevention interventions in adolescents.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/adolescentsalcohol useanimationbinge drinkingcluster-randomized controlled trialcomputer-tailoringweb-based interventionsAdolescentAlcohol DrinkingBinge DrinkingComputersEthanolHumansRandomized Controlled Trials as TopicText Messagingresearch article34639280open access10.3390/ijerph181999781660-4601PMC8508351https://www.mdpi.com/1660-4601/18/19/9978/pdf?version=1632376849https://pmc.ncbi.nlm.nih.gov/articles/PMC8508351/pdf
