Adaptação transcultural do adolescent Asthma Self-Efficacy Questionnaire (AASEQ) para a população brasileira

Abstract

Introduction: Self-efficacy is considered an important predictor of therapeutic adherence and health promotion in achieving the control of chronic diseases, and its evaluation is essential for the management of asthma. So far, in Brazil, there are no specific instruments to assess the self-efficacy of adolescents with asthma. Objective: To provide the cross-cultural adaptation of the Adolescent Asthma SelfEfficacy Questionnaire (AASEQ) for the Brazilian population. Methods: This is an exploratory study, which involves the cross-cultural adaptation of the AASEQ. The study followed international recommendations, including the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN), and involved translation steps, synthesis of translations, reverse translation, synthesis of reverse translations, review by an external researcher, evaluation and approval of the author of the original version, analysis by a multidisciplinary committee of experts and pretest. Similar to the original study, internal consistency was tested; content validity; convergent validity; discriminant validity, and construct validity, verified by the Confirmatory Factor Analysis (AFC). Results: The instrument adapted for the Portuguese in Brazil proved to have a content equivalent to the original, in which adequate comprehensibility indexes were obtained for the Brazilian population. A total of 148 adolescents with asthma aged 12 to 18 years were considered eligible to participate of the study. The AASEQ showed adequate value for internal consistency. The construct validity showed a regular adjustment to the data. The convergent and discriminant validities were confirmed through correlations with the General SelfEfficacy Scale (GSES), Asthma Knowledge Scale, and the number of hospitalizations for asthma in the last year. Conclusion: The AASEQ proved to be an appropriate questionnaire to assess asthma self-efficacy in Brazilian adolescents
