Sociological traditions suggest that role identities serve to give meaning and impor­tance to past behavior as well as provide direction for future behavior. The Exercise Identity Scale (EIS) was developed to measure the extent to which exercise contributes to an individual's role-identity. This investigation examined age norms on the EIS. Data were collected from three populations including a convenience sample of 203 college students enrolled in three elective health-studies courses (92% Caucasian and 63% female), 441 of 531 (83%) law enforcement employees in a state department concerned with public safety (98% Caucasian and 96% male), and 1253 of 4000 (32%) randomly selected employees of a large financial services corporation (66% female) . Exercise identity was measured by the sum of nine scaled items. To test the overall effects, these three samples were combined (N=1882). ANOVA results revealed statistically significant main effects for both exercise and age group for exercise identity scores and ruled out statistically significant gender differences . Neither the gender and age group interaction nor the exercise and age group interaction were statistically significant . Examination of the means reveals consistent score differences between exercisers and nonexercisers for exercise identity scores of approxi­mately one standard deviation. There was also a trend for higher mean scores at the younger ages. These norms provide comparative information for other researchers who are inter­ested in the use of the EIS in their efforts to study and predict fitness behaviors.
