Abstract

Irrational beliefs are a risk factor for mental ill-health and exercise dependence. In addition to this, researchers have also proposed that body image inflexibility can determine mental health and behavioural outcomes. However, research is yet to explore whether and to what extent irrational beliefs and body image inflexibility align to influence mental health and exercise dependence. We examined the latent profile structure of irrational beliefs and body image inflexibility, and how these latent profiles relate to mental health and exercise dependence in exercise active adults. Results indicate a two class profile, whereby class 1 is characterized by high irrational beliefs and body image inflexibility, and class 2 is characterized by low irrational beliefs and body image inflexibility. Those in class 1 reported significantly greater depression, anxiety, stress, and exercise dependence than those in class 2 (p ≤ .02). The findings are discussed in relation to the implications for practitioners in the mental health of exercise participants.
