Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <sec id="abs1-1" sec-type="section"> <title>Objective:</title> <p>Some investigators have suggested subtyping bulimia nervosa (BN) by anorexia nervosa (AN) history. We examined trait‐level and momentary eating‐related and psychosocial factors in BN with and without an AN history.</p> </sec> <sec id="abs1-2" sec-type="section"> <title>Method:</title> <p>Interview, questionnaire, and ecological momentary assessment data of eating‐related and psychological symptoms were collected from 122 women with BN, including 43 with (BN+) and 79 without an AN history (BN−).</p> </sec> <sec id="abs1-3" sec-type="section"> <title>Results:</title> <p>Body mass index (kg/m<sup>2</sup>) was lower in BN+ than BN− (<italic>p</italic> = 0.001). Groups did not differ on trait‐level anxiety, shape/weight concerns, psychiatric comorbidity, or dietary restraint; or on momentary anxiety, dietary restriction, binge eating, purging, or exercise frequency, or affective patterns surrounding binge/purge behaviors. Negative affect increased prior to exercise and decreased thereafter in BN+ but not BN−, although groups did not statistically differ.</p> </sec> <sec id="abs1-4" sec-type="section"> <title>Discussion:</title> <p>Results do not support formally subtyping BN by AN history. Exercise in BN+ may modulate negative affect, which could have important treatment implications. © 2012 by Wiley Periodicals, Inc. (Int J Eat Disord 2013)</p> </sec> </abstract>
