Validity and reliability of the Czech adaptation of the Sport Motivation Scale-6

Abstract

This study examined the factorial validity and reliability of the Czech adaptation of the Sport Motivation Scale-6 (SMS-6) in a sample of 303 competitive athletes. Confirmatory factor analysis supported the six-factor structure after the removal of one low-loading item, with acceptable model fit. Reliability indices for all subscales ranged from satisfactory to strong. The validated Czech SMS-6 provides a theoretically grounded and reliable tool for assessing the quality of sport motivation among Czech athletes.
