There is extensive evidence for the clinical significance of Purging Disorder (PD), an eating disorder characterized by recurrent purging behavior (self-induced vomiting, laxative use, and diuretic use) in the absence of binge eating and low weight (Smith, Crowther, & Lavender, 2017). Research on the personally profile of PD is still developing but evidence supports an association with impulsivity (Brown, Haedt-Matt, & Keel, 2011). The personally underpinnings of impulsive behavior include several different impulsigenic traits. To investigate personally contributors to impulsive behavior among women with PD, we compared 31 women with PD to 57 women with bulimia nervosa (BN) and 31 healthy control women on four impulsigenic traits: negative urgency, lack of premeditation, lack of perseverance, and sensation seeking. Compared to healthy controls, women with PD reported significantly greater levels of negative urgency, but no significant differences on the other traits. Compared to BN, PD was associated with significantly lower levels of negative urgency, but no other significant differences. Compared with controls, women in the BN group had significantly higher scores on lack of premeditation and lack of perseverance, but no significant difference on sensation seeking. Findings indicate negative urgency is a potentially important personally trait for distinguishing those with PD.
