This study aimed to assess the relationship between self‐disgust and sensory processing within eating psychopathology. Five hundred and ninety‐one women with a self‐reported diagnosis of anorexia nervosa, bulimia nervosa or who had no previous history of an eating disorder completed a battery of online questionnaires measuring disgust, emotion and sensory variables. Those with an eating disorder reported significantly higher rates of self‐disgust than those with no history of disordered eating. In groups of women with self‐reported bulimia, self‐disgust was associated with sensation avoidance and sensation seeking. Within the group with anorexia nervosa, self‐disgust was associated with low registration and sensation seeking. This report is the first to examine the expression of the emotion self‐disgust within eating psychopathology and examine associations of this factor with sensory processing. The emotion self‐disgust needs to be further examined to understand its possible role in the onset and maintenance of disordered eating.
