Detecting mental health problems after paediatric acquired brain injury: A pilot Rasch analysis of the strengths and difficulties questionnaire.

The parent-reported Strengths and Difficulties Questionnaire (SDQ-P) is commonly used to assess for mental health problems, but its psychometric properties have not been studied in the paediatric Acquired Brain Injury (ABI) population. This study investigated the properties of the SDQ-P and its subscales in this population using Rasch analysis. One hundred and forty-three SDQ-Ps and 123 Impact Supplements were analyzed. Sixty-nine percent of SDQ-Ps were completed by female carers, 59% of young people were male, and 58% had Traumatic Brain Injury (TBI). In this population the SDQ-P Total Difficulties Scale and the Conduct Problems subscale showed questionable construct validity. The individual subscales and Impact Supplement did not meet the criteria for reliability. Two items had disordered thresholds. The individual subscales showed mistargeting and 13-24% person misfit. Two items were significantly underdiscriminating. There was differential item functioning with age and time post-injury, and local dependence between subscale items. The Total Difficulties scale was multidimensional. The most easily endorsed items were in keeping with common symptoms of brain injury. These findings suggest the SDQ-P in its current form may not be a reliable and valid assessment measure for mental health difficulties in the paediatric ABI population and requires further investigation.

What do Kids with Acquired Brain Injury Want? Mapping Neuropsychological Rehabilitation Goals to the International Classification of Functioning, Disability and Health.

OBJECTIVE: To increase understanding of the community neuropsychological rehabilitation goals of young people with acquired brain injuries (ABIs). METHOD: Three hundred twenty-six neuropsychological rehabilitation goals were extracted from the clinical records of 98 young people with ABIs. The participants were 59% male, 2-19 years old, and 64% had a traumatic brain injury. Goals were coded using the International Classification of Functioning, Disability and Health: Children and Youth Version (ICF-CY). Descriptive statistical analysis was performed to assess the distribution of goals across the ICF-CY. Chi-squared and Cramer's V were used to identify demographic and injury-related associations of goal type. RESULTS: The distribution of goals was 52% activities and participation (AP), 28% body functions (BF), 20% environmental factors (EF), and <1% body structures (BS). The number of EF goals increased with age at assessment (V = .14). Non-traumatic causes of ABIs were associated with more EF goals (V = .12). There was no association between sex or time post-injury and the distribution of goals across the ICF-CY. CONCLUSIONS: Young people with ABIs have a wide range of community neuropsychological rehabilitation goals that require an individualized, context-sensitive, and interdisciplinary approach. Community neuropsychological rehabilitation services may wish to ensure they are resourced to focus intervention on AP, with increasing consideration for EF as a young person progresses through adolescence. The findings of this research support models of community neuropsychological rehabilitation that enable wellness by combining direct rehabilitative interventions with attention to social context and systemic working across agencies.
