However, little research has examined whether within\u2010person fluctuations in ER longitudinally predict ED behaviors in daily life or the mechanisms of ER effects. Investigating daily ER could help us better understand why people experience ED behaviors at a given time. We examined whether day\u2010to\u2010day changes in adaptive (e.g., cognitive reappraisal) and maladaptive (e.g., rumination) ER longitudinally predicted core ED behaviors (binge eating, purging, dieting) and whether changes in affect mediated effects.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method<\/jats:title>\n                    <jats:p>\n                      Female participants (\n                      <jats:italic>N<\/jats:italic>\n                      \u2009=\u2009688) ages 15\u201330 from the Michigan State University Twin Registry reported their adaptive and maladaptive ER use, negative affect (NA), positive affect (PA), binge eating, purging, and dieting on 49 consecutive days. Using structural equation modeling, we examined whether within\u2010person fluctuations in ER predicted same\u2010 and next\u2010day ED behaviors and whether changes in affect mediated longitudinal ER effects.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Greater maladaptive ER predicted increased likelihood of same\u2010day binge eating and next\u2010day binge eating and purging. The association between maladaptive ER and next\u2010day binge eating and purging was mediated by increased next\u2010day NA. In contrast, dieting was more closely related to changes in PA. Adaptive ER did not predict reduced likelihood of any ED behavior.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Maladaptive ER may longitudinally increase risk for binge eating and purging by amplifying NA.

We found that maladaptive emotion regulation (e.g., rumination) was associated with a higher likelihood of binge eating and purging on the next day because it predicted increased next\u2010day negative affect. In contrast, dieting was more closely tied to fluctuations in positive affect. Targeting daily emotion regulation and affective processes may help disrupt cycles of disordered eating.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1002\/eat.24162","type":"journal-article","created":{"date-parts":[[2024,2,9]],"date-time":"2024-02-09T01:54:37Z","timestamp":1707443677000},"page":"1181-1191","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Changes in affect longitudinally mediate associations between emotion regulation strategy use and disordered eating"],"prefix":"10.1002","volume":"57","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9262-3683","authenticated-orcid":false,"given":"Megan E.","family":"Mikhail","sequence":"first","affiliation":[{"name":"Department of Psychology Michigan State University  East Lansing Michigan USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5538-7431","authenticated-orcid":false,"given":"S.
