Abstract：The present study was based on Psychological Need Satisfaction in Exercise Scale proposed by Wilson, Rogers, Rodgers and Wild (2006) and aimed to develop a revised scale of Chinese version for the Taiwanese athletes. The theoretical foundation of the scale was according to Self-determination Theory by Deci and Ryan (1985) that includes three factors competence, autonomy and relevance with a total of 18 questions. This investigation consisted of two studies and the constructive validity as well as internal validity was used in two different studies, Scales of item analysis, exploratory factor analysis, confirmatory factor analysis and simultaneous multigroup covariance analyses were carried out. The results showed that the scale has construct validity of ”content representativeness” and the ”internal structure.” This study concluded that the scale had good reliability and validity, future research could use the scale to combine with other study areas.
