Based on self-determination theory, the purpose of the present study was to provide the first Italian validation of two different instrument to assess the exercise behaviour: the Mullan et al.'s (1997) BREQ which measures external, introjected, identified and intrinsic forms of regulation and Ryan et al.'s (1997) MPAM-R, which assesses five distinct motives for physical activity (appearance, health and fitness, social, competence, and enjoyment). Confirmatory factor analysis conducted on data collected from 1995 students attending three different secondary schools empirically supported respectively the four-factor structure of behavioural regulation and the five-factor structure of motives for physical activity, supporting convergent and discriminant validity of both scales. Furthermore, multi-group confirmatory factor analysis showed the invariance of the factor structures, structural parameters and correlations of the two scales across gender. Criterion-related validity of the scales also received partial empirical support. Finally, the factor structure of behavioural regulation and motives for physical activity was empirically supported when both constructs were included in a single measurement model.
