The premorbid adjustment of 85 six- to sixteen-year-old children with traumatic brain injury was assessed by means of standardized rating forms that were completed by the children's parents and teachers. Parents and teachers were in moderate agreement when rating children's premorbid functioning. Less than 11% of the children appeared to have premorbid disturbances. Premorbid adjustment did not appear to be clearly related to injury severity or to type of injury. It is concluded that premorbid behavioral and psychosocial factors are not strongly related to the incidence of traumatic brain injury in a sample of children with predominantly relatively severe injuries.
