Examining a mediation model of body image-related cognitive fusion, intuitive eating, and eating disorder symptom severity in a clinical sample.

Abstract

This study sought to explore the associations between Intuitive Eating (IE), eating disorder (ED) symptom severity, and body image-related cognitive fusion within a clinical sample. IE was also examined as a possible mediator in the relationship between body image-related fusion and ED symptoms. This study includes cross-sectional analyses with data from 100 adult females and 75 adolescent females seeking residential treatment for an ED. Self-reported demographic information, ED symptoms, IE behaviors, and body image-related cognitive fusion were collected from participants within the first week of treatment following admission to the same residential ED treatment facility. ED symptom severity was significantly negatively associated with three of the four domains of IE; unconditional permission to eat, reliance on hunger and satiety cues, and body-food choice congruence. A significant mediational effect of IE on the relationship between body image-related fusion and ED symptoms through IE behaviors was observed (β = 11.3, SE = 0.003, p < 0.001). This effect was only observed for the unconditional permission to eat (β = 0.13, p = 0.003) and reliance on hunger and satiety cues (β = 0.10, p = 0.005) domains of IE when the domains were subsequently analyzed individually. Unconditional permission to eat and reliance on hunger and satiety cues appear to be particularly influential domains of IE in the relationship between body image-related fusion and ED symptom severity. It is possible that changes in these IE domains may be mechanisms through which body image-related fusion influences ED symptoms. Future longitudinal research is needed to better understand the relationship between body image-related cognitive fusion and IE and the potential for targeting these constructs specifically in the context of ED treatment.
