Abstrakt: Objective: This study sought to examine whether anxiety sensitivity was associated with eating disorder (ED) symptom severity among patients with severe EDs, and to determine whether this relationship was mediated by experiential avoidance.
Method: Adolescent and adult females (N = 625) seeking residential ED treatment completed self-report measures of anxiety sensitivity, experiential avoidance, and ED psychopathology. Linear regression evaluated the cross-sectional association between ED symptom severity and three dimensions of anxiety sensitivity (social, physical, and cognitive). Regression-based mediation analysis with bootstrapping tested the associations among the three dimensions of anxiety sensitivity and ED symptom severity through experiential avoidance.
Results: The social dimension of anxiety sensitivity was positively associated with severity of ED psychopathology. Experiential avoidance mediated this association.
Discussion: ED symptoms in this sample were more severe among patients who endorsed greater concern about appearing nervous or anxious to others. The current results indicate that this relationship was driven by a tendency to avoid experiences that evoke emotional discomfort. If replicated, these findings suggest that targeting both social anxiety sensitivity and experiential avoidance may improve ED treatment outcomes. Further study of the mechanistic relationships among social anxiety sensitivity, experiential avoidance, and ED psychopathology, is warranted.
