Abstract:
The Basic Psychological Needs in Exercise Scale (BPNES; Vlachopoulos &Michailidou, 2006) is a domain-specific self-report instrument designed to assess the extentto which the needs for autonomy, competence, and relatedness are fulfilled in exercise. Thestructural and predictive validity of BPNES responses were evaluated among communityexercise program participants together with the extent to which the responses weremeasurement invariant across the community and the private fitness contexts. A sample of851 participants attending community exercise programs and two samples totaling 1012participants attending private fitness centers were used. The results supported thehypothesized dimensionality, internal consistency, and predictive validity of the BPNESamong community-program exercise participants, as well as the partial metric invariance,partial measurement error invariance and partial scalar invariance of BPNES responsesacross the exercise contexts.
