One’s athletic identity, developed and maintained by others as well as the self, is likely important in sustaining long-term physical activity over many years. The 21-item Athletic Identity Questionnaire (AIQ) is presented as a multidimensional measure of the components of athletic identity that reflects an attribute all people possess to varying degrees and encompasses exercise, sports, and physical activity. Confirmatory factor analyses in two samples of young adults (n = 446 and 485) supported a first-order model of four correlated factors: athletic appearance; importance of exercise/ sports/ physical activity; competence; and encouragement from others. A latent factor of physical activity with two indicators—stage of exercise behavior and exercise frequency per week—correlated significantly with the four athletic identity factors in both samples (r = 0.57–0.89 in Sample 1, r = 0.56–0.90 in Sample 2), and this 5-factor measurement model also represented an adequate fit. Results provide support for the reliability and validity of the AIQ.
