However, there is no evidence on the performance in the implementation of expressive suppression in BN. The aim of this study was to investigate brain activity (in terms of ERP) and self\u2010reported ratings associated with expressive suppression of emotions elicited by positive and negative stimuli in women with BN.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>Event\u2010related potentials (ERP) were recorded from 23 female individuals with BN and 26 matched healthy controls. Participants were shown emotional pictures under two conditions: using facial suppression or attentively viewing. High\u2010density EEG was used to characterize the time course of emotion regulation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>ERP amplitudes varied significantly with valence, with positive (vs. neutral and negative) pictures eliciting larger ERP amplitudes. However, no significant differences in ERP were observed between the groups or conditions. The BN group reported lower self\u2010efficacy in implementing suppression compared to the control group, the latter with a positive correlation between the perceived self\u2010efficacy and the change in emotional arousal between conditions.<\/jats:p><\/jats:sec><jats:sec><jats:title>Discussion<\/jats:title><jats:p>Our findings suggest that individuals with BN might have difficulties in monitoring the emotion regulation process compared to healthy individuals. This suggests that other processes (e.g., metacognitive difficulties, self\u2010esteem) rather than a failure to implement suppression, might underlie these results. However, further research is needed to validate this interpretation. Implications and directions for future research are discussed.<\/jats:p><\/jats:sec>","DOI":"10.1002\/jclp.23761","type":"journal-article","created":{"date-parts":[[2024,12,20]],"date-time":"2024-12-20T08:37:29Z","timestamp":1734683849000},"page":"158-170","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Expressive Suppression of Emotions in Bulimia Nervosa: An Electroencephalography Study"],"prefix":"10.1002","volume":"81","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0929-4514","authenticated-orcid":false,"given":"Lorena","family":"Desdentado","sequence":"first","affiliation":[{"name":"Clinical and Health Psychology, Institute of Psychology and Education Ulm University Ulm Germany"},{"name":"CIBER of Physiopathology of Obesity and Nutrition (CIBEROBN), Instituto de Salud Carlos III Madrid Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0512-565X","authenticated-orcid":false,"given":"Olga","family":"Pollatos","sequence":"additional","affiliation":[{"name":"Clinical and Health Psychology, Institute of Psychology and Education Ulm University Ulm Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,12,20]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cpr.2009.11.004"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1176\/appi.books.9780890425596"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/0022-3999(94)90005-1"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijpsycho.2015.02.022"},{"key":"e_1_2_9_6_1","volume-title":"Beck Depression Inventory Manual","author":"Beck A.
