Stop to think: prevention programme of use/abuse of alcohol in school aged adolescents


The "Stop to think" prevention programme was developed in the classroom with interactive methodologies with an objective to prevent alcohol use/abuse among school-aged adolescents. Quasi-experimental study was used as a method, with pre- and post-test. 178 participants were involved, 70 of them were in experimental group and 108 were in the control group.

The Alcohol Knowledge Questionnaire, Alcohol Expectancy Questionnaire and Social Skills Rating System were used.

The experimental group showed a positive evolution of knowledge and expectations about alcohol, perception of peer alcohol use and reported consumption.

The programme proved to be effective in stabilizing alcohol consumption, increasing knowledge, stabilizing the positive expectations, and in the perception of peer alcohol use.
