In sports research, defining athletic identity of individuals is an important study subject. The subject owes its significance to the fact that an individual's athletic identity affects his other identities throughout his life span. The aim of this study is to test the reliability and validity of the Turkish version of Athletic Identity Measurement Scale (AIMS). The sample of the study was selected among 501 university students, composed of 194 female and 307 male students. The original "Athletic Identity Measurement Scale" is a 10-item inventory developed by Brewer, Van Raalte and Linder (1993) and was used to measure the athletic identity levels of subjects. Subjects were asked to select the responses that fit them the most on a five point Likert type scale. According to the results of this study, 7-item multidimensional structure of AIMS was proven reliable and valid for Turkish population.
