PURPOSE: This study assessed psychiatric and personality characteristics in relation to pediatric functional seizures (FS). METHODS: In a 1:1 prospectively matched-control study design, children with documented FS (confirmed via video EEG; ages 13–18) were matched to controls (MCs) on income, sex, race, and age. Primary outcomes were Behavior Assessment System for Children, Second Edition (BASC-2) and Millon Adolescent Clinical Inventory (MACI). Secondary measures included questionnaires assessing trauma, somatization, body awareness and quality of life (QOL). T-tests investigated differences between groups on T-scores. Due to lack of significant outcomes, an experimental analysis was conducted assessing differences in number of clinically elevated BASC-2 and MACI scores between groups. Binary logistic regressions determined the influences of clinically elevated scores on likelihood participants have FS. T-tests assessed differences on secondary measures. RESULTS: Participants included 84 children, 42 with FS and 42 MCs (Children with FS: Mean(age)=15.4, Interquartile Range(age)=3; 73.5% female; 59.5% white). Children with FS had greater parent-reported somatization (t(23)=5.67, p
