Abstract
|
|
|
|
The purpose of this study was to validate the Exercise Addiction Inventory (Terry et al., 2004) and Exercise Dependence Scale-Revised (Downs, et al., 2004) for those who participate in sports regularly in Korea. The original scales were translated into Korean and reverse-translated. Participants were 504 adults (287 males, 217 females) who participate in sports at least twice weekly. Exploratory and confirmatory factor analyses were conducted to determine the appropriateness of the EAI and EDS-R factor structures, and assess reliability and validity. EAI demonstrated the same 6-item 1-factor structure as the original scale, and EDS-R demonstrated the same 21-item, 7-factor structure as the original scale, both with adequate internal consistency. The EAI and EDS-R showed a significant positive correlation with the Exercise Addiction Test (EAQ) confirming validity. The results indicate that each sub-factor of the EAI and EDS-R independently explains exercise addiction in a Korean sample. Implications and limitations are discussed.
