Psychometric Properties of the Sport Motivation Scale: An Evaluation with College Varsity Athletes from the U.S.

Motivation, particularly different types of motivation (i.e., intrinsic, extrinsic, and amotivation), is a topic that has been of interest to both psychologists and sport psychologists. One area of interest in sport psychology is the assessment of different types of motivation. The Sport Motivation Scale (SMS) (Pelletier et al., 1995) was created to assess an athlete's intrinsic motivation, extrinsic-motivation, and a motivation toward sport participation. The psychometric properties of the SMS, however, have not been tested on a sample of college athletes in the U.S., which is an important component if researchers and applied sport psychologists are to use the SMS with this population. A total of 270 U.S. college athletes participated in this study. Results provided some evidence for the reliability and validity of the SMS for this population, although a confirmatory factor analysis yielded relatively poor fit indices, indicating problems with model specification. A "piecewise" model testing approach, in which different components of the model were tested separately, indicated that the biggest problems with model specification may involve the extrinsic and amotivation components of the measure.
