RESUMEN
Aesthetic athletes face higher risks of disordered eating, and perfectionism is one of the determinants involved. While research suggests that perfectionism in sport may play a role in physical and psychological well-being, its influence remains to be confirmed. As such, further examination of the influence of perfectionism on health is warranted as it could lead to better interventions. This preregistered research sought to shed new light on these relationships by investigating the mediating role of passion in the perfectionism-disordered eating relationship as well as physical and psychological well-being in aesthetic sports. In Study 1, 229 American recreational and competitive athletes practicing either gymnastics (n = 150) or artistic swimming (n = 79) were recruited on MTurk to complete an online questionnaire. The same recruitment procedure was used for Study 2, with 107 American gymnasts (n = 69) and artistic swimmers (n = 38) completing the questionnaire at two timepoints, one year apart. Results from path analyses showed that socially prescribed perfectionism was associated with obsessive passion, which in turn was associated with disordered eating. Self-oriented perfectionism was associated with both obsessive and harmonious passion, the latter being more adaptative as it was associated with physical and psychological well-being. Thus, the way one engages in aesthetic sports matters, as engaging with obsessive passion may take a toll on one's health and lead to disordered eating. Conversely, fostering harmonious engagement seems to temper the negative associations between perfectionism and health outcomes and promote positive relationships with athlete's well-being, but requires further study.
