VALIDITY AND RELIABILITY OF SITUATIONAL MOTIVATION SCALE FOR PHYSICAL EDUCATION CLASS ENVIRONMENT

The aim of this study was to test reliability and validity of Situational Motivation Scale for physical education class environment. Participants were 291 secondary-school students (M±SDAge= 13.38 ±0.83) who are 154 boys (M±SDAge= 13.37 ±0.88) and 137 girls (M± SDAge= 13.39 ±0.77) aged between 12 to 15 years. Confirmatory factor analysis and Cronbach Alpha coefficients was used to confirm its validity and reliability in physical education class environment. Findings regarding the construct validity of the scale demonstrated that four-factor model showed acceptable to good fit to the data (χ2/sd= 2.62, RMSEA= 0.06, NFI= 0.94, NNFI= 0.96, CFI= 0.97, GFI= 0.93 and AGFI= 0.89). The Cronbach’s alpha coefficients were 0.71 for intrinsic motivation, 0.72 for identified regulation, 0.79 for external regulation, and 0.78 for amotivation. Results showed that the SIMS can be used to determine secondary school students’ situational motivational levels in physical education class environment.
