Development of the Compulsive Exercising Scale for Extreme Sports Participants

The purpose of this study was to develop a scale to measure extreme sports participants' levels of compulsive exercising. There are a number of compulsive exercising scales; however, none of them is targeted for extreme sports participants, whose emotional responses differ from those of non-extreme sports participants. Five hundred extreme sports participants were involved in this study, which included literature analysis, expert review, and exploratory and confirmatory factor analysis. Firstly, 95 items were selected from previous studies related to extreme sports and compulsive exercising. Secondly, nine experts scrutinized the content validity of the 95 items, and 82 items were found to be valid. Thirdly, the 82-item survey was initially administered to 253 participants for the purposes of exploratory factor analysis. Lastly, the 20-item survey that came out as a result of the 82 items being put through the exploratory factor analysis was distributed to the other 247 participants in the confirmatory factor analysis. In the final results, 16 items regarding the four factors of the "withdrawal symptom", "attachment", "struggle", and "obsession" were confirmed. The factors used to measure extreme sports participants' compulsiveness in this study reflect somewhat different dimensions from those developed in previous studies for non-extreme sports participants or exercisers. Only factors in the affective and behavioral dimensions are included in the present study's scale, while factors in the cognitive or the combined cognitive, affective, and behavioral dimensions were investigated in previous studies. This explains the need for the present study.
