The aim of the present study was to translate and evaluate the psychometric properties of the Perceived Autonomy Support: Exercise Climate Questionnaire that measures the autonomy support given by fitness instructors in accordance with the self-determination theory. In order to fulfill such purpose, it was collected a sample of 935 fitness exercisers, male (N = 344) and female (N = 591) in 16 different Health Centers in the area of Lisbon and west coast of Portugal. The analysis performed revealed that the translated version had an adequate internal, temporal, construct and predictive validity, supporting its use with Portuguese exercisers.
