A broad cross-section of elite athletes (n = 83) was compared to a normative sample (n = 2,436) of nonathletes on the 13 self-concept scales for the Self-Description Questionnaire III (SDQIII). On these scales athletes had substantially higher Physical Ability self-concepts than nonathletes, but did not differ on Physical Appearance self-concepts. There were smaller differences favoring athletes on social scales (Same Sex, Opposite Sex, and Parent Relationships), Global Esteem, and the total self-concept. Group differences were not statistically significant for the academic scales (Math, Verbal, Academic, and Problem Solving) and Emotional self-concept, whereas nonathletes had marginally higher Spiritual and Honesty self-concepts. Athlete/nonathlete differences varied somewhat according to gender, generally favoring women athletes. Because the pattern of group differences (e.g., large differences in Physical Ability and minimal differences in Academic self-concept scales) is reasonably similar to a priori predictions, the results provide further support for the construct validity of SDQIII responses.
