Abstract: Objectives: To assess the clinical significance and distinctiveness of purging disorder (PD) from other eating disorder (ED) diagnoses. Method: Participants included 3127 women consecutively admitted to an ED treatment centre (246 PD, 465 anorexia nervosa restrictive [AN‐R], 327 AN‐binge purging [AN‐BP], 1436 bulimia nervosa [BN], 360 binge eating disorder [BED], 177 atypical AN and 116 unspecified feeding or eating disorder [UFED]) who were diagnosed according to DSM‐5 criteria. Additionally, 822 control participants were recruited from the community. All participants completed measures assessing ED symptoms (EDI‐2), general psychopathology (SCL‐90‐R) and personality (TCI‐R). Results: Patients with PD, when compared to controls, scored significantly higher on the EDI‐2 and SCL‐90‐R, and most TCI‐R dimensions. Most of the significant differences between PD and the other ED diagnoses emerged between PD and AN‐R, followed by Atypical‐AN, UFED, AN‐BP and BED, with patients with PD typically reporting higher scores on the EDI‐2 and SCL‐90‐R subscales. Significant differences between PD and BN were also present, but to a lesser extent. The findings for personality varied amongst the different ED diagnoses. Conclusions: PD is a clinically significant disorder, which seems to be more similar to BN than it is to AN and the other ED subtypes.
