| Abstract: | This paper presents five studies with 2,420 total participants on the development and validation of the Exercise Dependence Scale (EDS), which is conceptualized based on the Diagnostic and Statistical Manual-IV (APA, 1994) criteria for substance dependence, and differentiates among at-risk, nondependent-symptomatic, and nondependent-asymptomatic exercisers. Results of the studies revealed evidence for the a priori hypothesized components, acceptable test-retest and internal consistency reliability, and content and concurrent validity of the EDS. Individuals at-risk for exercise dependence reported more strenuous exercise, perfectionism, and self-efficacy compared to the nondependent groups. The findings provide initial support for the EDS and indicate the need for a multifaceted approach to its conceptualization and measurement. |
