This article describes the contrivance of a recreational sport constraints scale with in controvertible reliability and validity. Two studies, the qualitative and the quantitative analyses were examined. In the qualitative study, a recreational sport constraints scale was created by means of inducing and categorizing in-depth interviews with students and answers of open-ended questionnaires. In the quantitative study, the discrimination was found by the item analysis among 979 samples of students employed by experiments from 12 colleges in the central Taiwan, while four aspects significantly developed by the explanatory factor analysis were the constraints of experience, opportunity, society and individual. Given that the factor loading is between.532 ∼.806, the explanatory cumulative is 63.231% and the Cronbach α coefficient is between .8262 ∼.9035, the findings of the study suggest that the new denies manifests itself in both high constructive validity and reliability.
