Abstract
The Sport Motivation Scale (SMS) is commonly used to measure motivation in young athletes. The purpose of this investigation was to examine the factorial validity of the SMS among a sample of senior athletes. A correlational research design, in addition to confirmatory factor analyses (CFAs), was used to examine the factor structure of the SMS in a sample of senior game participants at the Florida Senior State Championships held in Kissimmee, Fla, from November 28 to December 3, 2000. Results of psychometric testing on the SMS did not support the hypothesized factor structure of this instrument in assessing motivation in the senior athlete population.
