Funding: The Alerta Alcohol. Design and evaluation of web-based computer-tailored intervention for selective prevention of binge-drinking in adolescents project is financed by a grant from the Consejería de salud de la Junta de Andalucía, Spain; contract PI-0031-2014, register date: 04 August 2015.
Objective: To determine the effectiveness of the program ALERTA ALCOHOL, a web-based computer-tailored intervention, in preventing binge drinking in spanish adolescents aged from 16 to 18 years. We will analyze the effectiveness of the program taking into account the risk factors associated with this behavior and by using the I-change model.
Method: The design and validation of the program is carried out, based on the I-Change Model, and using focus and Delphi groups and a pilot study. Then a Cluster Randomized Controlled Trial is performed to test the effectiveness of Alerta Alcohol with students aged from 16 to 18 years, which will be implemented at high schools in Andalusia (southern Spain), who are randomized at school level into the experimental and control condition (EC and CC). The EG receives the Alerta Alcohol intervention, which consists in four sessions at school (baseline questionnaire, two sessions that provide three scenarios: at home, celebrations, and public places, and the evaluation). In the three scenarios, information and motivational messages are provided to prevent binge-drinking (by improving the knowledge, risk perception, self-esteem, attitude, social influence, and self-efficacy). In addition, two booster sessions are developed at home. The CC only fills the baseline and the evaluation questionnaire and then receives access to the intervention (i.e., a waiting list control condition). The evaluation takes places after four months since the baseline and the primary result is the reduction of binge drinking in the previous 30 days and alcohol use in the last week. A process evaluation will be conducted and analyses will carry out to determine the differential effect of the program dosage (quality of the implementation) on the program outcomes.
