Examining the Commitment for Competitive Sports

Development of Japanese Version of Sports Commitment Scale

Abstract

The purpose of this study was to develop a Japanese version of the Sport Commitment Scale (SCS-J), originally developed by Scanlan et al. (1993a; 1993b), and examine the relationship between sports commitment and the frequency of competitive sports participation. The participants were 1125 college students who played competitive sports in collegiate athletics or another sports activity (male: 822, female: 285). The Sport Commitment Scale (Scanlan et al., 1993a; 1993b) was translated into Japanese using the back translation method, and the reliability and validity of the SCS-J were examined. The results indicated the reliability (internal consistency, reproducibility) and validity (construct validity, criterion-related validity) of the SCS-J and illustrated the scale's usefulness. In addition, the result of examining the relationship between sports commitment and frequency of sports participation, sports commitment was positively associated with the frequency of sports participation. This result supported previous findings of a relationship between sports commitment and sports participation. In conclusion, this study confirmed the reliability, validity, and usefulness of the SCS-J.
