Abstract Behavior-based addictions are widely researched phenomena, though they are not included in the DSM-IV-TR (2000) with their substance-based counterparts. Exercise dependence is one such behavioral addiction that has garnered a lot of interest, yet is still poorly understood. The goal of the current study was to contribute to the understanding of exercise dependence by examining its latent structure. A community sample of 577 exercisers completed the Exercise Dependence Scale, Revised (EDS-R; Hausenblas and Downs, 2002b). The seven subscales of the EDS-R were used as indicators of exercise dependence in two taxometric analyses, MAMBAC and MAXEIG. Results of these analyses consistently indicated that the latent structure of exercise dependence is dimensional in nature, suggesting that exercise dependence represents an extreme on the full spectrum of all exercise behavior.
