The purpose of this study was to examine select psychometric properties of the Behavioral in Exercise Questionnaire (BREQ; Mullen, Markland, & , 1997). To accomplish this aim, data were gathered in 2 phases to evaluate BREQ’s factorial composition and structure and the relation between the BREQ, satisfaction, exercise behavior, and relevant motivational constructs. Participants measures assessing psychological need satisfaction, optimism, perceived control, exercise behavior, and the BREQ. Phase 1 results supported original 4-factor measurement model and a simplex model of structural between latentBREQconstructs suggested within self-determination theory (Deci & Ryan, 1985), and results supported the positive relations between more -determined motives and greater psychological need satisfaction and frequent exercise . Phase 2 results provided further construct validity evidence for the by linking subscale scores with greater perceived behavioral control in a manner with theory (Deci & Ryan, 1985). Collectively, these results further the construct validity of the BREQ and lend credence to the notion of measuring motivation from a multidimensional perspective using self-determination as a guiding framework in the exercise domain.
