PD has received relatively little attention, and questions remain about the clinical significance of \u201cpurging\u201d by exercise that is driven or compulsive (i.e., as extreme compensatory or weight\u2010control behavior). The little available research suggests that individuals who use exercise as a compensatory behavior might have less eating\u2010disorder psychopathology than those who purge by vomiting or laxatives, but those studies have had smaller sample sizes, defined PD using low\u2010frequency thresholds, and defined exercise without weight\u2010compensatory or driven elements.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>Participants (<jats:italic>N<\/jats:italic>\u2009=\u20092,017) completed a web\u2010based survey with established measures of eating\u2010disorder psychopathology, depression, and physical activity.

Findings provide further support for the clinical significance of PD. Clinicians and researchers should recognize the severity of driven exercise as a compensatory behavior, and the need for further epidemiological and treatment research.<\/jats:p><\/jats:sec>","DOI":"10.1002\/eat.22811","type":"journal-article","created":{"date-parts":[[2017,12,7]],"date-time":"2017-12-07T14:06:55Z","timestamp":1512655615000},"page":"139-145","source":"Crossref","is-referenced-by-count":20,"title":["Driven exercise in the absence of binge eating: Implications for purging disorder"],"prefix":"10.1002","volume":"51","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6425-514X","authenticated-orcid":false,"given":"Janet A.","family":"Lydecker","sequence":"first","affiliation":[{"name":"Department of Psychiatry, Yale School of Medicine New Haven Connecticut United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Megan","family":"Shea","sequence":"additional","affiliation":[{"name":"Department of Psychiatry, Yale School of Medicine New Haven Connecticut United States"},{"name":"Amherst College Amherst Massachusetts United States"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0245-3444","authenticated-orcid":false,"given":"Carlos M.","family":"Grilo","sequence":"additional","affiliation":[{"name":"Department of Psychiatry, Yale School of Medicine New Haven Connecticut United States"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2017,12,7]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1176\/appi.books.9780890425596"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.3758\/s13428-011-0081-0"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.20167"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/erv.769"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1177\/1745691610393980"},{"key":"e_1_2_5_7_1","doi-asserted-by":"crossref","first-page":"373","DOI":"10.1007\/978-981-287-104-6_11","volume-title":"Encyclopedia of feeding and eating disorders","author":"Cook B.","year":"2017"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.22551"},{"key":"e_1_2_5_9_1","volume-title":"Anorexia and bulimia","author":"Fairburn C.
