Abstract
This study investigated the psychometric properties of Persian version of exercise dependence scale in Iranian athletes. To do this, 230 athletes from group and individual sport were selected through accessible sampling method. Selected athletes were professional who accomplished exercise dependence scale. According to the result of experimental factor analysis, one structure with 6 factors components was found which encompass 72/71% of the total variability of the data. Result of Confirmatory factor analysis revealed six factor structures of exercise dependence (Withdrawal, Continuance, Tolerance, Lack of control, Time, Intention effect) has a good fit. The internal consistency (0/7) and (0/86) showed that exercise dependence questionnaire has suitable reliability coefficients. Therefore, the results of the present study showed that after deleting 3 items, the exercise dependence questionnaire has satisfactory reliability and validity which researchers are able to use exercise dependence questionnaire as a reliable and valid tool to measure exercise dependence.
