The Coaching Behavior Scale for Sport (CBS-S) is designed to evaluate coaches' involvement in developing athletes, taking into considerations the complex training and competition environment. Although the CBS-S has been used in a number of empirical studies, the factor structure of the instrument has not been examined rigorously. The present study was, therefore, conducted to assess the factor structure of the CBS-S for Singaporean youth athletes. A total of 519 participants completed the CBS-S, and their responses were examined with confirmatory factor analysis (CFA) and recent exploratory structural equation modeling (ESEM). Both seven-factor CFA and ESEM models ft to the sample data adequately. In addition, the sizes of factor loadings on target factors were substantial and found comparable between the CFA and ESEM solutions. The findings from this study supported the factorial validity of the CBS-S for the present sample.
