Validity of the compulsive exercise test in regular exercisers

ABSTRACT

Measurement of compulsive exercise is important for the study of eating pathology in individuals who regularly participate in sport and exercise. The current study examined the factor structure, internal consistency and validity of the compulsive exercise test (CET) in regular exercisers. Participants were recruited via the internet and from sport clubs (n = 313 adults; M = 32 years; 57% female). A three-factor model for the CET was supported which included the weight control exercise, avoidance and rule-driven behaviour, and mood improvement subscales (fit statistics for the three-factor model: χ²_{SB =} 4.39; CFI = .95; NNFI = .94, RMSEA = .100, 95% CI: .093—.110, AIC = 656.92). The subscales lack of exercise enjoyment and exercise rigidity were not retained. All factors demonstrated acceptable internal consistency with Cronbach’s α = .77 to .91. The weight control exercise and avoidance and rule-driven behaviour subscales were significantly related to eating disorder symptoms. Given the association between CET subscales and eating disorder symptoms, the CET three-factor model may be informative when assessing eating pathology in individuals who regularly exercise.
