Athletic Identity may be defined as being the degree of importance, strength and exclusivity that is attached to the athlete's role which is maintained by him/herself and his/her context (Cieslak, 2004). In this study, using a confirmatory factor analysis, the measure of Athletic Identity (AIMS-plus) was examined. A total of 650 athletes completed the AIMS-plus. The psychometric features of the original scale were replicated to the Portuguese population. Validity and reliability were positive. AIMS-plus and AIMS were high correlated suggesting that both scales derive from similar athletic identity concepts. These results suggest that AIMS-plus seems to be an acceptable psychometric instrument and a good measure to be explored in research and intervention for athletic identity. It's also recommended further studies of the psychometric characteristics.
