The Exercise Confidence Survey is a questionnaire measuring self-efficacy for engaging in regular physical activity. Sallis (1996) has identified two dimensions within the Exercise Confidence Survey: sticking to it and making time for exercise. The purpose of the present study was to investigate the psychometric properties of the French version of this questionnaire. Two hundred ninety-three volunteers filled in the French version of the Exercise Confidence Survey. A confirmatory factor analysis confirmed the two-factor model proposed by Sallis (1996). However, we also found a best-fit two-factor model in which one item of each original dimension proposed by Sallis actually was allocated to the other dimension. Finally, self-efficacy is significantly associated with the other components of transtheoretical model (TTM): stages of change, decisional balance, and processes of change. These results demonstrate that the French version of the Exercise Confidence Survey exhibits satisfactory internal consistency and can be validly applied to a French-speaking population.
