Self-disgust mediates the relationship between dysfunctional cognitions and depressive symptomatology.
Disgust has been linked to several psychopathologies, although a role in depression has been questioned. However, it has recently been proposed that rather than general disgust sensitivity, disgust directed toward the self (self-disgust) may influence the development of depression, providing a causal link between dysfunctional cognitions and depressive symptomatology. This possibility was examined by developing a scale to measure self-disgust (the Self-Disgust Scale; SDS) and then using mediator analysis to determine if self-disgust was able to explain the relationship between dysfunctional cognitions (measured with the use of the Dysfunctional Attitudes Scale) and depressive symptomatology (measured with the use of the Beck Depression Inventory and the Depression, Anxiety and Stress Scale). The developed SDS was found to exhibit a high level of internal consistency, test-retest reliability, and concurrent validity. Principal-components analysis revealed two factors to underlie responses to SDS items: the 'Disgusting self,' concerned with enduring, context independent aspects of the self, and 'Disgusting ways,' concerned with behavior. Self-disgust was found to mediate the relationship between dysfunctional cognitions and depressive symptomatology, demonstrating for the first time that self-disgust plays a role in depression.
