To address this gap, we compared responses on the Difficulties in Emotion Regulation Scale\u2010Positive questionnaire and the traditional DERS questionnaire (measuring negative affect dysregulation) between females with AN (<jats:italic>n<\/jats:italic>\u00a0=\u00a030) and demographically\u2010matched controls without an eating disorder history (NC; <jats:italic>n<\/jats:italic>\u00a0=\u00a030) and examined relations between positive emotion regulation and clinical symptoms. Results indicated that individuals with AN demonstrated greater difficulty regulating negative (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001, <jats:italic>d<\/jats:italic>\u00a0=\u00a02.75) and positive (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001, <jats:italic>d<\/jats:italic>\u00a0=\u00a01.08) emotions compared to NC participants. Specifically, the AN group reported heightened positive emotion nonacceptance (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.004, <jats:italic>d<\/jats:italic>\u00a0=\u00a00.78) and impulsivity (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.003, <jats:italic>d<\/jats:italic>\u00a0=\u00a00.81). Greater positive emotion nonacceptance was associated with higher anxiety (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.015) and depression (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.022) among individuals with AN. Unexpectedly, more positive emotion impulsivity was associated with less restrictive eating in AN (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001). Findings were largely maintained even after controlling for negative emotion dysregulation and psychotropic medication use. The results suggest that reducing shame related to positive emotions could improve mood in AN; alternatively, relinquishing control when experiencing positive emotion could reduce restriction. More research is warranted on positive emotion regulation as a treatment target for AN.<\/jats:p>","DOI":"10.1002\/erv.2973","type":"journal-article","created":{"date-parts":[[2023,3,1]],"date-time":"2023-03-01T04:29:51Z","timestamp":1677644991000},"page":"520-528","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Difficulties with positive emotion regulation in anorexia nervosa"],"prefix":"10.1002","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3782-1841","authenticated-orcid":false,"given":"Bolade M.","family":"Santos","sequence":"first","affiliation":[{"name":"Department of Psychiatry and Behavioral Sciences University of Minnesota  Minneapolis Minnesota USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ann F.","family":"Haynos","sequence":"additional","affiliation":[{"name":"Department of Psychiatry and Behavioral Sciences University of Minnesota  Minneapolis Minnesota USA"},{"name":"Department of Psychology Virginia Commonwealth University  Richmond Virginia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,2,28]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1176\/appi.books.9780890425596"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/jclp.22638"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1001\/archpsyc.1961.01710120031004"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.2307\/1165312"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.20931"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10862\u2010015\u20109514\u2010x"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0133827"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.neubiorev.2015.08.011"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.23147"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1037\/ccp0000396"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1002\/da.22490"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.psychres.2016.01.078"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1186\/1471\u2010244x\u201013\u2010291"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.janxdis.2009.02.001"},{"key":"e_1_2_7_16_1","doi-asserted-by":"publisher","DOI":"10.1037\/a0034010"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1002\/1098\u2010108x(199412)16:4(363::aid\u2010eat2260160405)3.0.co;2\u2010#"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.23041"},{"key":"e_1_2_7_19_1","doi-asserted-by":"publisher","DOI":"10.1177\/1745691617692106"},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.1023\/b:joba.0000007455.08539.94"},{"key":"e_1_2_7_21_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40337\u2010021\u201000417\u20105"},{"key":"e_1_2_7_22_1","doi-asserted-by":"publisher","DOI":"10.1037\/abn0000202"},{"key":"e_1_2_7_23_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468\u20102850.2011.01250.x"},{"key":"e_1_2_7_24_1","doi-asserted-by":"publisher","DOI":"10.1007\/s40519\u2010014\u20100161\u20100"},{"key":"e_1_2_7_25_1","doi-asserted-by":"publisher","DOI":"10.1002\/eat.22675"},{"key":"e_1_2_7_26_1","doi-asserted-by":"publisher","DOI":"10.1002\/acr.20561"},{"key":"e_1_2_7_27_1","doi-asserted-by":"publisher","DOI":"10.1002\/erv.2706"},{"key":"e_1_2_7_28_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.psychres.2015.12.004"},{"key":"e_1_2_7_29_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cpr.2015.05.010"},{"key":"e_1_2_7_30_1","doi-asserted-by":"publisher","DOI":"10.3389\/fpsyg.2017.00780"},{"key":"e_1_2_7_31_1","doi-asserted-by":"publisher","DOI":"10.2174\/1871530318666180213111637"},{"key":"e_1_2_7_32_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jad.2013.12.037"},{"key":"e_1_2_7_33_1","first-page":"224","volume-title":"The self\u2010report method, inHandbook of research methods in personality psychology","author":"Paulhus D.
