Abstract
Alcohol is a substance commonly used by adolescents. Due to the relevant role alcohol expectancies have for understanding adolescent use behavior, valid and reliable instruments need to be designed to evaluate these beliefs. The purpose of this study was to validate the Spanish version of the Alcohol Expectancy Questionnaire-Adolescent, Brief (AEQ-AB). The sample was comprised of 315 adolescents aged 14 to 18 years who filled in an ad hoc questionnaire on demographic data the Spanish version of the EQ and the (AEQ-AB). Factor analysis showed that the original seven-item model clustered in two factors (positive and negative), fit the Spanish sample correctly. The reliability and validity analysis showed adequate translation and adaptation of the AEQ-AB questionnaire in Spanish adolescents.
