Some contend however that BN\u2010NP is more like binge eating disorder (BED) than BN\u2010P. This study examines clinical characteristics, eating disorder symptomatology, and Axis I comorbidity in BN\u2010NP, BN\u2010P, and BED groups to establish whether BN\u2010NP more closely resembles BN\u2010P or BED.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>Women with BN\u2010P (<jats:italic>n<\/jats:italic>\u2009=\u200929), BN\u2010NP (<jats:italic>n<\/jats:italic>\u2009=\u200929), and BED (<jats:italic>n<\/jats:italic>\u2009=\u200954) were assessed at baseline in an outpatient psychotherapy trial for those with binge eating.

Both BN subtypes had higher Restraint and Drive for Thinness scores than BED. Body Dissatisfaction was highest in BN\u2010NP and predicted BN\u2010NP compared to BN\u2010P. Higher Restraint and lower BMI predicted BN\u2010NP relative to BED. BN\u2010NP resembled BED with higher lifetime BMIs; and weight\u2010loss clinic than eating disorder clinic attendances relative to the BN\u2010P subtype. Psychiatric comorbidity was comparable except for higher lifetime cannabis use disorder in the BN\u2010NP than BN\u2010P subtype<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>These results suggest that BN\u2010NP sits between BN\u2010P and BED however the high distress driving inappropriate compensatory behaviors in BN\u2010P requires specialist eating disorder treatment. These results support retaining the BN\u2010NP group within the BN category. Further research is needed to determine whether there are meaningful differences in outcome over follow\u2010up. \u00a9 2013 Wiley Periodicals, Inc.
