Abstract
Exercise dependence, a process in which a person feels compelled to exercise and suffers physical and psychological symptoms when exercise is withdrawn, appears to be commonplace among bodybuilders. The purpose of this study was determining the validity and reliability of the Persian version of the bodybuilding dependence. In this regard 196 male and female bodybuilders selected by random cluster sampling and then completed the questionnaire. This scale at the first, with use of translation-back translation methods, face validity and translate accuracy of the Persian version of the questionnaire was confirmed. Then Confirmatory factor analysis (CFA) based on structural equations was used for validation of structure of the questionnaire, Cronbach alpha coefficient was used for validation of internal consistency of the questionnaire. The results for Confirmatory factor analysis showed that the first model bodybuilding dependence scale was not supported the favorable fit. But after eliminating the one question, the second model with 8 questions, had an acceptable fit index (Root Mean Square Error of Approximation=0.06, Comparative fit index=0.91, Tucker Lewis index=0.86) and internal consistency (Internal consistency for whole of scale 0.74 and subscales mastery dependence, training dependence and social dependence were equal to, 0.80, 0.70 and 0.73 respectively). Therefore, The Persian version of the modified bodybuilding dependence scale can be characterized as a valid and reliable tool to evaluate and study the bodybuilding dependence of Iranian athletes will benefit.
