Abstract
Objectives- Exercise addiction can be secondary to eating disorders, or a primary condition in the absence of another disorder. Currently, to determine secondary exercise addiction, two screening tools must be administered. The aim of this study was to validate a novel screening tool able to stratify between primary and secondary exercise addiction, called the secondary exercise addiction scale (SEAS). Methods- Phase 1 (n = 339) described the statistical reduction of an initial pool of scale items. Phase 2 (n = 382) used a confirmatory factor analysis (CFA) to examine the robustness of the latent structure. Phase 3 (n = 721) determined cut off scores for the eating disorder and exercise addiction sections of the SEAS and determine concurrent reliability with the exercise addiction inventory (EAI) and the SCOFF questionnaires. Phase 4 (n = 45) determined test–retest reliability. Results- Phase 1 extracted two components: exercise addiction and eating disorder symptomology, with 11 items retained. The CFA in Phase 2 showed an acceptable fit to the proposed model (comparative fit index = 0.93, Tucker Lewis Index = 0.91). Phase 3 determined cut off scores of ≥ 28 (specificity = 91.97%), and ≥ 20 (specificity = 96.27%) in the respective exercise addiction and eating disorders sections of the SEAS. The respective sections also correlated well with the EAI (r = 0.70, p = < 0.001) and the SCOFF (r = 0.72, p = < 0.001). Phase 4 showed excellent test–retest reliability (exercise addiction r = 0.95, p = < 0.001, eating disorders r = 0.93, p = < 0.001). Conclusion- The SEAS appears to be a valid and reliable tool for measuring primary and secondary exercise addiction. Further studies are warranted to further validate this tool amongst clinical populations. Level of evidence- Level III: evidence obtained from cohort or case–control analytic studies.
