AbstractThe aim of this study was to investigate the factor structure of a Spanish version of the Sport Motivation Scale adapted to physical 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 completed the Learning and Performance Orientation in Physical Education Classes Questionnaire. We examined the factor structure of each model using confirmatory factor analysis and also assessed internal consistency and convergent validity. The results showed that all three models in Spanish produce good indicators of fitness, but we suggest using the seven-factor model (χ(2)/gl = 2.73; ECVI = 1.38) as it produces better values when adapted to physical education, that five-factor model (χ(2)/gl = 2.82; ECVI = 1.44) and three-factor model (χ(2)/gl = 3.02; ECVI = 1.53). Key PointsPhysical education research conducted in Spain has used the version of SMS designed to assess motivation in sport, but validity reliability and validity results in physical education have not been reported.Results of the present study lend support to the factorial validity and internal reliability of three alternative factor structures (3, 5, and 7 factors) of SMS adapted to Physical Education in Spanish.Although all three models in Spanish produce good indicators of fitness, but we suggest using the seven-factor model.
