Few studies have examined the self-reported mental health of children with an acquired brain injury (ABI). The current study aimed to: 1) identify levels of child-reported depressive and anxiety symptoms and poor self-concept, 2) investigate demographic and injury-related factors associated with children's mood and self-concept, and 3) examine associations between children's self-reported mental health and parents' reports of children's emotional and behavioral functioning in children specifically with traumatic brain injury (TBI). 122 children (66% male) aged 8-16 years with ABI of mixed etiology were consecutively recruited through an outpatient rehabilitation clinic. Children were administered the Beck Youth Inventories -Second Edition, and parents completed the Adaptive Behaviour Assessment System and the Child Behaviour Checklist (CBCL). Relative to the norms, 16.4% of children scored in the clinical range for the depression and anxiety scales, and 24.6% reported clinically low self-concept. Children with lower functional status had greater anxiety symptoms. Older children (13-16 years) reported significantly higher depressive and anxiety symptoms and lower self-concept than younger children (8-12 years). A significant interaction between age and sex indicated that older girls reported greater depressive and anxiety symptoms than younger girls whereas no age-based differences were found for boys.Parent-reported total emotional and behavioral problems were positively associated with children's self-reported depressive and anxiety symptoms and were negatively correlated with self-concept. These findings indicate that adolescents, particularly girls, may be at heightened risk of poor mental health following ABI. Further research investigating the reasons for these demographic differences may inform developmentally sensitive interventions.

People with severe traumatic brain injury (TBI) often make errors on everyday tasks that compromise their safety and independence. Such errors potentially arise from the breakdown or failure of multiple cognitive processes. This study aimed to investigate cognitive deficits underlying error behavior on a home-based version of the Cooking Task (HBCT) following TBI. Participants included 45 adults (9 females, 36 males) with severe TBI aged 18–64 years (M = 37.91, SD = 13.43). Participants were administered the HBCT in their home kitchens, with audiovisual recordings taken to enable scoring of total errors and error subtypes (Omissions, Additions, Estimations, Substitutions, Commentary/Questions, Dangerous Behavior, Goal Achievement). Participants also completed a battery of neuropsychological tests, including the Trail Making Test, Hopkins Verbal Learning Test-Revised, Digit Span, Zoo Map test, Modified Stroop Test, and Hayling Sentence Completion Test. After controlling for cooking experience, greater Omissions and Estimation errors, lack of goal achievement, and longer completion time were significantly associated with poorer attention, memory, and executive functioning. These findings indicate that errors on naturalistic tasks arise from deficits in multiple cognitive domains. Assessment of error behavior in a real life setting provides insight into individuals' functional abilities which can guide rehabilitation planning and lifestyle support.
