This study appraises the results of an intervention to prevent drinkdriving in a cohort of pre-drivers in the region of Catalonia (Spain). The program applied, based on attitude change, sets out to reduce significantly the risk of being involved in drink-driving. A classic quasiexperimental pretest-posttest design with control group was used, and two questionnaires were applied: a general one measuring several risk factors, and another one specifically addressing the question of alcohol. The study was carried out with three groups: a) experimental 1, which received the entire program, b) experimental 2, which received a part of the program, and c) control, which did not receive the benefits of the program. Results from the factor analysis (PCA) and the repeatedmeasures ANOVA suggest that young pre-drivers who received the program obtained better results in road safety and showed less risk of drink-driving than those who did not receive the program or received only part of it. Significant differences were also found between men and women. The results confirm the effectiveness of the attitude-change program and the possibility of reducing alcohol use among young predrivers.
