Studies comparing those who do and do not participate in research on eating disorder treatment are scarce, but necessary to evaluate the impact of self\u2010selection bias on outcomes. All consecutive underweight adult first admissions (<jats:italic>N<\/jats:italic> = 392) to an integrated inpatient (IP)\u2010partial hospital (PH) behavioral specialty program were invited to participate in a longitudinal study of eating disorder treatment. Demographic and hospital course data were collected on participants (<jats:italic>n<\/jats:italic> = 234) and non\u2010participants (<jats:italic>n<\/jats:italic> = 158). Participants and non\u2010participants had similar BMI at admission, lengths of stay, and weight gain rates. Participants were less likely than non\u2010participants to end treatment prematurely from IP and were discharged at a higher BMI; the effect size was small. Few differences in hospital course were observed between participants and non\u2010participants. Although participants were more likely to transition to PH and were discharged at a higher BMI, completion of step\u2010down to PH within this integrated IP\u2010PH program rather than research participation status at admission was a better indicator of discharge BMI, which remains the strongest predictor of long\u2010term weight\u2010maintenance in eating disorders.<\/jats:p>","DOI":"10.1002\/eat.22650","type":"journal-article","created":{"date-parts":[[2017,2,22]],"date-time":"2017-02-22T15:16:50Z","timestamp":1487776610000},"page":"602-605","source":"Crossref","is-referenced-by-count":6,"title":["Self\u2010selection bias in eating disorders outcomes research: Does treatment response of underweight research participants and non\u2010participants differ?"],"prefix":"10.1002","volume":"50","author":[{"given":"Colleen C.","family":"Schreyer","sequence":"first","affiliation":[{"name":"Johns Hopkins School of Medicine Baltimore Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Graham W.","family":"Redgrave","sequence":"additional","affiliation":[{"name":"Johns Hopkins School of Medicine Baltimore Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennifer L.","family":"Hansen","sequence":"additional","affiliation":[{"name":"Johns Hopkins School of Public Health Baltimore Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Angela S.","family":"Guarda","sequence":"additional","affiliation":[{"name":"Johns Hopkins School of Medicine Baltimore Maryland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2017,2,22]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1037\/0022-3514.51.6.1173"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM200006223422506"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.20513"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(13)61940-6"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.psychres.2012.04.037"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1037\/0033-2909.112.1.155"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.3758\/BF03193146"},{"key":"e_1_2_6_9_1","volume-title":"Structured clinical interview for dsm\u20105 diagnoses\u2010 clinical version","author":"First M.
