This study aimed to determine the prevalence, clinical correlates and predictive factors of catatonia in adolescents with ASD, focusing on sociodemographic, behavioural and affective characteristics.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A total of 107 adolescents aged 12\u201320\u2009years with ASD were evaluated at a tertiary child and adolescent psychiatry outpatient clinic. The diagnosis of catatonia was established using DSM\u20105 criteria and the Bush\u2013Francis Catatonia Rating Scale (BFCRS). ASD severity, repetitive behaviours and internalizing symptoms were assessed using the Global Assessment Scale, the Autism Behaviour Checklist (ABC), the Repetitive Behaviour Scale\u2013Revised (RBS\u2010R) and the Revised Child Anxiety and Depression Scale\u2013Parent version (RCADS\u2010P). Group comparisons, correlation analyses and binary logistic regression were performed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Catatonia was identified in 21.5% of participants. The most frequent symptoms were stereotypy (73.8%), impulsivity (37.4%), echolalia (36.4%), verbigeration (30.8%) and agitation\/excitement (30.8%). Female sex, greater ASD severity, depressive symptoms and separation anxiety were significantly associated with catatonia. The catatonia group demonstrated higher scores on the ABC\u2010Relationship Building, RBS\u2010R\u2010Stereotyped Behaviour and RCADS\u2010P\u2010Depression subscales. Logistic regression revealed that female gender and clinically significant separation anxiety symptoms were independent predictors of catatonia (Nagelkerke\n                      <jats:italic>R<\/jats:italic>\n                      <jats:sup>2<\/jats:sup>\n                      \u2009=\u20090.26,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.001).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>These findings highlight the importance of targeted screening for catatonia in ASD populations, particularly in females and individuals with co\u2010occurring separation anxiety symptoms.
