The association between neuropsychological performance and self-reported traumatic brain injury in a sample of adult male prisoners in the UK.

This study employed a correlational and group comparison design to investigate whether self-report of traumatic brain injury (TBI) in a sample of male prisoners screened using the Brain Injury Screening Index (BISI) was associated with impaired cognitive performance on standardised questionnaires and neuropsychological tests. A total of 139 male prisoners who reported having suffered a TBI in the BISI were interviewed, and completed further questionnaires and neuropsychological assessments. Their results were compared to 50 prisoners who had no reported history of TBI.
