Based on the partial \u03b7<jats:sup>2<\/jats:sup> values, the distinction between BN and EDNOS\u2010BN accounted for &lt; 5% of the criterion variance in general psychopathology measures. Post hoc analyses comparing EDNOS\u2010BN with objective bulimic episodes (OBEs; <jats:italic>n<\/jats:italic> = 34) versus no OBEs (<jats:italic>n<\/jats:italic> = 23) found greater EDEQ\u20104 Restraint subscale scores for EDNOS\u2010BN without OBEs.
