Abstract：The purpose of this study was, based on Eccles and Wigfield's theory (1995), to develop a Chinese language scale to measure university students' expectancy and value beliefs in sports. Two studies (N=421 and 347) were conducted with a series of back-translation, item analysis, exploratory and confirmatory factor analyses. Four factors were confirmed, including ability expectancy, required effort, psychological cost of failure, and task value. Predictive validity tests with the amount of physical activity as a criterion, and a known group difference method with gender difference as a criterion were also conducted, to examine the construct validity of the scale. Finally, a 17-item, Chinese version of scale for measuring ”Expectancy and Value Beliefs Scale in Sports for University Students” was developed. (Full text)
