This study investigated the relationships among the construct of athletic identity, life satisfaction and self-concept among adolescent males and females. Fifty students from a suburban high school participated in this study. Forty-eight participants completed a demographic questionnaire, the Athletic Identity Measurement Scale (AIMS), the Multidimensional Students Life Satisfaction Scale (MSLSS), and the Multidimensional Self-Concept Scale (MSCS). The study utilized recommendations of previous researchers to examine the level with which adolescent athletes identify with the athlete role and how that level impacts their overall life satisfaction, including how they perceive themselves. One specific component of athletic identity, sport exclusivity, was also examined. This investigation revealed that as athletic identity increases, self-concept increases. This is consistent with past literature as it relates to college aged athletes and other adult athletes; however, this has not been studied in adolescents until this point. Thus, this finding is striking and important as it relates directly to the fields of education and school psychology. No significant effects were seen with regards to life satisfaction or exclusivity. Implications for school psychologists, limitations of this investigation, and future suggested areas of investigation were discussed.
