Little is understood regarding the correlates and drivers of EDA; understanding these better may lead to targeted interventions and support strategies. Cross\u2010sectional data from parent\u2010rated measures were analyzed for 63 children referred to a specialist neurodevelopmental clinic in the United Kingdom. The relationship between EDA traits and a number of psychological (intolerance of uncertainty, anxiety, emotional dysregulation [reactivity and dysphoria], cognitive inflexibility, alexithymia [i.e., difficulty identifying emotions]), and neurodevelopmental (autistic and ADHD) traits was tested. No differences in EDA traits were found by diagnostic group (autistic vs. not\u2010autistic) or gender (male and female). Across the whole sample, EDA traits were negatively correlated with age and positively correlated with emotional dysregulation reactivity, ADHD traits, cognitive inflexibility, intolerance of uncertainty and alexithymia. EDA was not associated with autistic traits or anxiety. Path models were used to identify which cognitive and behavioral features predicted EDA scores, once inter\u2010correlations among predictors were controlled for. Only emotional dysregulation, ADHD traits and age predicted EDA\u2010Q scores. Further research is needed to assess how these variables contribute to EDA in larger more diverse samples, capturing potentially unmeasured variables, and exploring possible mediation pathways.<\/jats:p>","DOI":"10.1002\/aur.70384","type":"journal-article","created":{"date-parts":[[2026,10,24]],"date-time":"2026-10-24T02:45:01Z","timestamp":1792809901000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Psychological and Neurodevelopmental Correlates of Extreme Demand Avoidance in a Clinical Sample, an Exploratory Study"],"prefix":"10.1002","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7598-5340","authenticated-orcid":false,"given":"Oliver","family":"Lack","sequence":"first","affiliation":[{"name":"Department of Child and Adolescent Psychiatry, Institute of Psychiatry, Psychology &amp; Neuroscience King's College London  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9513-6917","authenticated-orcid":false,"given":"Matthew J.","family":"Hollocks","sequence":"additional","affiliation":[{"name":"Department of Child and Adolescent Psychiatry, Institute of Psychiatry, Psychology &amp; Neuroscience King's College London  London UK"},{"name":"South London and Maudsley NHS Foundation Trust  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gillian","family":"Baird","sequence":"additional","affiliation":[{"name":"Newcomen Centre, Evelina London Children's Hospital, Guy's &amp; St Thomas' NHS Foundation Trust  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ann","family":"Ozsivadjian","sequence":"additional","affiliation":[{"name":"Department of Child and Adolescent Psychiatry, Institute of Psychiatry, Psychology &amp; Neuroscience King's College London  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0577-1897","authenticated-orcid":false,"given":"Michael","family":"Absoud","sequence":"additional","affiliation":[{"name":"Newcomen Centre, Evelina London Children's Hospital, Guy's &amp; St Thomas' NHS Foundation Trust  London UK"},{"name":"Department of Women and Children's Health, School of Life Course Sciences, Faculty of Life Sciences and Medicine King's College London  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francesca","family":"Happ\u00e9","sequence":"additional","affiliation":[{"name":"Social, Genetic and Developmental Psychiatry Centre, Institute of Psychiatry, Psychology &amp; Neuroscience King's College London  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5450-0823","authenticated-orcid":false,"given":"Emily","family":"Simonoff","sequence":"additional","affiliation":[{"name":"Department of Child and Adolescent Psychiatry, Institute of Psychiatry, Psychology &amp; Neuroscience King's College London  London UK"},{"name":"South London and Maudsley NHS Foundation Trust  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,10,23]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00787\u2010015\u20100815\u20100"},{"key":"e_1_2_11_3_1","doi-asserted-by":"crossref","DOI":"10.1176\/appi.books.9780890425596","volume-title":"Diagnostic and Statistical Manual of Mental Disorders","author":"American Psychiatric Association","year":"2013"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10803\u2010024\u201006246\u20100"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jaac.2024.11.004"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10803\u2010013\u20102001\u2010x"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s42761\u2010025\u201000318\u20109"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0005\u20107967(01)00092\u20104"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.janxdis.2006.03.014"},{"key":"e_1_2_11_10_1","unstructured":"Cheung S.
