The aim of this study was to examine the validity and reliability of the Turkish version of Behavioural Regulation in Exercise Questionnaire-3 (BREQ-3). Four hundred-one male and 299 female exercisers participated in this study. The Behavioural Regulation in Exercise Questionnaire-3 BREQ-3, Basic Psychological Needs in Exercise Scale and Goal Orientation in Exercise Measure were administered with personal information form to all participants. The psychometric proporties of the scale were investigated using confirmatory factor analysis, internal consistency, convergent and discriminant validity. Findings regarding the construct validity of the scale demonstrated that six-factor model showed acceptable fit to the data. The results demonstrated an adequate internal consistency. Furthermore, correlations of the behavioral regulations with goal orientations and basic needs satisfactions in exercise provided the evidence for the convergent and discriminant validity of the measure. In sum, results indicated that BREQ-3 is a reliable and valid scale in within the context of exercise in Turkey.
