Adaptación y validación del Cuestionario Breve de Confianza Situacional en universitarios mexicanos que consumen alcohol

Abstract

Introduction: self-efficacy for the control of alcohol consumption is a relevant variable in addiction intervention programs. The Brief Situational Confidence Questionnaire (CBCS) was developed for adult problem drinkers in Canada and subsequently included in intervention programs for adults and adolescents in Mexico. Although, the only data reported in our country has been its internal consistency index. Therefore, it was proposed to evaluate whether the questionnaire had similar psychometric characteristics, as previously reported with Canadian adults, with Mexican college students. Objective: obtain the validity and reliability of the CBCS with Mexican students. Method: 1,175 university volunteers, alcohol consumers in the last year and who reported two or more indicators for DSM 5 alcohol use disorder. The evaluation followed the standards for the development and review of instrumental studies. Results: the confirmatory factor analysis yielded a final model of a single dimension of four reagents: testing control over consumption, physical need, conflicts with others and pleasant moments with others, with an internal consistency index of .78. Discussion and conclusions: unlike what was found with adult problem drinkers, in this work a questionnaire composed of a single dimension was obtained, possibly due to the characteristics of the population, with an acceptable level of reliability. The questionnaire can be used in intervention programs or in studies that measure the situational self-efficacy for alcohol consumption in Mexican university students.
