Abstract
The personality scores from Cattell's 16 PF for 188 patients who had been referred for neuropsychological assessment following motor vehicle incidents were analyzed as a function of the severity of neuropsychological impairment (Halstead-Reitan Index) and time since the injury. Patients who were impaired (Index >0.4) exhibited lower scores on Factor B (more concrete thinking), Factor E (more submissive), and Factor F (more cautious) than patients who were not impaired. The presence of impairment accommodated only 10% of the variance in Factor E scores, associated with the largest group difference. There were no significant differences between scores on any of the personality factors, verbal intelligence, or standardized reading ability as a function of time since the injury.
