Psychometric properties of the controlling coach behaviors scale for Japanese athletes

Abstract

Two studies examined the validity and reliability of the Japanese version of the Controlling Coach Behaviors Scale (CCBS). The CCBS is a multidimensional self-report measure designed to evaluate sports coaches’ controlling interpersonal style from the perspective of self-determination theory (SDT). It comprises 15 items measuring the controlling use of rewards, negative conditional regard, intimidation, and excessive personal control on a seven-point Likert scale. The study 1 sample comprised 526 university student-athletes (Mage = 19.59 years, SD = ±0.94, 364 females) who completed the Japanese CCBS, which was developed through back-translation. Confirmatory factor analyses provided support for the tenability of the hypothesized factor structure of the Japanese CCBS (CFI=.927; NNFI=.909; RMSEA=.079). Moreover, the results supported the invariance of the scale across sex, sport types, and competitive levels. The subscale internal consistency and discriminant validity scores were all acceptable. Test-retest reliability evidence was obtained in Study 2 (N=108), suggesting a positive and significant intraclass correlation between the pre-test and the post-test CCBS (ICC range: .65–.87). These findings support the Japanese CCBS as a valid and reliable measure for use in research which will enhance our understanding of coaches’ controlling interpersonal styles in sports.
