Purpose: This research was to confirm the overall fit, reliability, convergent validity, and discriminate validity of the Passion Scale. Methods: Two hundred and twenty one senior high school elite athletes were voluntarily participated in the study. Their average age was 16.58 years. All the participants were asked to complete the Passion Scale. Results: The results of confirmatory factor analysis showed a two-factor oblique model of Passion Scale, named harmonious passion and obsessive passion. This theoretical model was found to be good overall fit (χ^2 (76)=183.44, p＜.05; RMSEA=.08; CFI=.97; NNFI=.96; PNFI=.79), reliability (R^2=.22~.67; ρ=.84~.88), convergent validity (λ=.48~.82, t=6.96~14.31, p＜.05), and discriminate validity (△χ2=180.28, p＜.05; r=.67~.83 for 90% Confidence Interval). Conclusion: It is suggested that the internal measurement model in Passion Scale has demonstrated all needed evidence of construct validity.
