OBJECTIVE: To describe the process of elaboration and validation of the Scale of Perceptions about Alcohol Consumption in Higher Education Students in a Portuguese sample, considering the relationship between alcohol use rates and students’ perceptions about the effects of this consumption. METHODS: The validation study included 531 Portuguese college freshmen who answered the instrument, which is composed of five items that express positive perceptions and five items that express negative perceptions about the effects of alcohol consumption. RESULTS: Evidence of content validity, internal structure and external variables were obtained. The results of the factor analysis confirm the distribution of positive and negative perceptions by two different factors according to the theoretical model. Adequate internal consistency indexes were obtained for each dimension. The data obtained showed expected correlations between the perceptions and consumption behaviors of the students, indicating evidence of criterion validity of the scale. Moreover, the study showed that different consumption patterns between men and women, with higher alcohol consumption in the students’ households and restaurants or cafés by male students, in addition to the similarity in the consumption pattern between the two genders in parties and bars or nightclubs. CONCLUSION: The data obtained show the validity of the instrument. In the discussion, the article presents considerations about the responsibility of higher education institutions in the prevention and reduction in consumption rates among their students.
