摘要：O presente estudo teve como objetivo realizar a tradução, adaptação transcultural, validação de construto, consistência interna e reprodutibilidade da Escala de Autoe cácia baseada nos Estágios de Mudança de Comportamento para a Prática de Atividade Física (EABEMC). A escala composta por 20 itens foi adaptada à realidade brasileira utilizando-se da técnica de back translation. Em termos empíricos testou-se a validade de construto e a consistência interna do instrumento em 281 técnicos servidores públicos de ambos os sexos maiores de 18 anos, enquanto a reprodutibilidade foi verificada em 91 universitários. Na análise fatorial exploratória, os 19 itens carregaram num único fator, com as cargas fatoriais variando de 0,41 a 0,88, explicando 52,7% da variância total das respostas dos sujeitos. A EABEMC apresentou boa consis- tência interna satisfatória (alfa de 0,94) e boa reprodutibilidade (CCI 0,60. A EABEMC alcançou níveis adequados de validade, consistência interna e reprodutibilidade, podendo ser utilizada para mensurar a autoe cácia para prática de atividade física.
其他摘要：The present study aimed to perform the translation, cross-cultural adaptation, and construct validation of the Self-Efficacy Scale based on the Stages of Behavior Change for Physical Activity Practice (SESBC), and also to test its internal consistency and reproducibility. The scale, composed of 20 items, was adapted to the Brazilian reality using the technique of back-translation. In empirical terms, construct validation and the internal consistency of the instrument were tested in 281 state public servant technicians of both sexes, older than 18 years, while reproducibility was tested in 91 university students. In the exploratory factor analysis, the 19 items loaded onto one single factor, and factor loadings varied from 0.41 to 0.88, explaining 52.7% of the total variance of the subjects’ responses. e SESBC showed good reliability in terms of internal consistency (alpha of 0.94) and good reproducibility in terms of test and re-test (ICC < 0.40-0.80) after two weeks. Of the 19 items, 17 presented ICC > 0.60. Therefore, the SESBC reached adequate levels of validity, internal consistency and reproducibility and can be used to measure self-efficacy for physical activity practice.
