Psychometric properties of the “sport motivation scale (sms)” adapted to physical education

The aim of this study was to investigate the factor structure of a spanish version of the sport motivation scale adapted to physi-cal education. a second aim was to test which one of three hypothesized models (three,five and seven-factor) provided best model fit. 758 spanish high school students completed the sport motivation scale adapted for physical education and also com-pleted the learning and performance orientation in physical education classes questionnaire. we examined the factor struc-ture of each model using confirmatory factor analysis and also assessed internal consistency and convergent validity. the re-sults showed that all three models in spanish produce good indicators of fitness,but we suggest using the seven-factor model (χ2/gl = 2.73; ecvi = 1.38) as it produces better values when adapted to physical education,that five-factor model (χ2/gl = 2.82; ecvi = 1.44) and three-factor model (χ2/gl = 3.02; ecvi = 1.53). ©journal of sports science and medicine.
