OBJECTIVES: The aim of the study was to explore the relationship between exercise identity and exercise dependence. We hypothesized that stronger exercise identities would be associated with greater odds of experiencing exercise dependence symptoms. DESIGN: Logistic regression was used to assess the extent of association between exercise identity and the risk of experiencing exercise dependence symptoms. METHOD: Participants (101) were recruited online via sports clubs and social networking sites and were asked to complete online measures of exercise identity and exercise dependence. RESULTS: The overall model fit was a significant improvement on the baseline model, but only the exercise beliefs factor was significantly associated with the odds of dependence symptoms, with higher scores on the belief scale predicting greater odds of experiencing dependence symptoms. Exercise role identity, in contrast, was not significantly associated with odds of experiencing dependence symptoms. Per cent correct classification was 55.9% for asymptomatic and 88.2% for symptomatic individuals and the overall per cent correct classification was 77.5%. CONCLUSIONS: The relation between identity and dependence could represent both a fruitful research avenue and a potential therapeutic target for those experiencing dependence symptoms; although our findings only showed a relationship between one of the two factors of the exercise identity measure and dependence. Longitudinal research is required to examine the relationship between identity and dependence in the context of other variables to better understand why some individuals become exercise dependent whereas others do not. STATEMENT OF CONTRIBUTION: What is already known on this subject? Exercise identity has been identified as an important determinant of exercise behaviour and studies within the exercise identity framework have proven elucidative with respect to the psychological processes that may underpin commitment to exercise. It has separately been established that some individuals may become dependent on exercise and exhibit symptoms indicative of a behavioural addiction to exercise according in line with clinical definitions. What does this study add? Psychological explanation for exercise dependence based on escalation of normal exercise identity processes. Empirical investigation of identity-dependence link using a sample of physically active individuals. Comparison of two alternative structures for the exercise identity construct.
