Introduction: Disgust has been identified to play a role in the development of several psychological disorders (1). Recent studies have tried to explore the relationship between disgust and eating disorders, with heterogeneous findings (2). Elevated levels of disgust are associated to traumatic events involving sexual victimization. One of the suggested mechanism implicated in this association is a feeling of mental contamination (3). Objectives: The aim of this study is to investigate the relationship between disgust and history of maltreatment in patients with Eating Disorder. We also predict that levels of propensity and sensitivity to disgust in patients diagnosed with Eating Disorders and Anxiety Disorders are higher than healthy controls. Methods: We enrolled 114 patients admitted in Psychiatric Unit of Careggi: 41 with diagnosis of Eating Disorder, 33 with Anxiety Disorders and 40 healthy controls. We administered to all groups: Childhood Trauma Questionnaire (CTQ), Eating Disorder Examination-2 (EDI-2), Disgust Propensity and Sensibility Scalerevised (DPSS-r). Results: We noted higher scores at DPSS-r in the two psychopathological groups compared to the healthy group, in accordance with previous literature (barchart 1, table 1). We found a significant linear correlation between the DPSS-R scores and the CTQ subscales Emotional Abuse and Physical Neglect (table 2). Disgust Propensity was finally identified as a possible mediator of the relationship between Emotional Abuse and altered Interoceptive Awareness (Indirect Effect: 0,59; I.C. 95%: 0,30-0,95) Conclusions: These preliminary data could suggest a possible role of childhood traumatic events in the development of Sensitivity and Propensity to Disgust in Eating Disorders patients.
