This study was focused on construct a reliable and valid scale of sport tourism constraints for the physically challenged based on confirmatory factor analysis. The questionnaires were used as research methods in this study with convenience sampling collected 400 questionnaires to the physically challenged that live at Northern Taiwan, Central Taiwan, and Southern Taiwan, and 326 questionnaires were retrieved, 262 valid questionnaires were received (with valid questionnaire rate of 80%). The results verify that the scale has a good level of convergent validity, discriminant validity, and composite reliability. Therefore, the sport tourism constraints scale for the physically challenged proposed by this study is a first-order-three-factor model with three factors. They are intrapersonal constraints, interpersonal constraints, and structural constraints.
