Given the important prognostic role that WS plays in ED course and outcome, we hypothesized that WS would represent a clinically useful indicator of impairment for bulimic syndromes. We further posited that WS would demonstrate incremental validity above\u2010and\u2010beyond other proposed indicators in explaining clinical impairment in bulimic syndromes. Participants were community\u2010recruited adults (<jats:italic>N<\/jats:italic>\u2009=\u2009101; 80.2% female) with full\u2010threshold (<jats:italic>n<\/jats:italic>\u2009=\u200951) or subthreshold (<jats:italic>n<\/jats:italic>\u2009=\u200950) bulimia nervosa. Other indicators of impairment included body mass index, frequency of inappropriate compensatory behaviors, lifetime history of any internalizing disorder, and multiple purging. Clinical impairment was assessed with the clinical impairment assessment (CIA). Hierarchical linear regression tested whether WS added to the explanation of CIA score variance above\u2010and\u2010beyond other indicators of bulimic\u2010syndrome impairment. WS was significantly associated with clinical impairment (<jats:italic>p<\/jats:italic>\u2009=\u2009.011), but did not demonstrate incremental validity over other independent variables in predicting CIA scores. WS explained an additional 1.7% of the variance in CIA scores above\u2010and\u2010beyond other variables and the independent effect of WS on CIA scores represented a medium\u2010sized effect (Cohen's <jats:italic>d<\/jats:italic>\u2009=\u20090.521). Results suggested that WS may be an indicator of ED\u2010related clinical impairment. Inquiring about WS could be an informative component of routine bulimic\u2010syndrome assessment, given that WS explains some of the variance in clinical impairment in bulimic syndromes.<\/jats:p>","DOI":"10.1002\/eat.22673","type":"journal-article","created":{"date-parts":[[2017,1,17]],"date-time":"2017-01-17T06:49:39Z","timestamp":1484635779000},"page":"672-678","source":"Crossref","is-referenced-by-count":7,"title":["Incremental validity of weight suppression in predicting clinical impairment in bulimic syndromes"],"prefix":"10.1002","volume":"50","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5723-3591","authenticated-orcid":false,"given":"Kelsey E.","family":"Hagan","sequence":"first","affiliation":[{"name":"Department of Psychology University of Kansas 1415 Jayhawk Blvd. Lawrence KS 66045"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kelsey E.","family":"Clark","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Kansas 1415 Jayhawk Blvd. Lawrence KS 66045"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kelsie T.","family":"Forbush","sequence":"additional","affiliation":[{"name":"Department of Psychology University of Kansas 1415 Jayhawk Blvd. Lawrence KS 66045"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2017,1,17]]},"reference":[{"key":"e_1_2_5_2_1","unstructured":"Advanced Analytics LLC.
