Background The purpose of this study was to evaluate the validity of the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) for examining outcomes after multiple trauma and to investigate whether the addition of items selected to measure cognitive function could improve the sensitivity of the SF-36 for identifying differences in outcomes for patients with and without head injury. Methods One thousand two hundred thirty patients discharged from 12 trauma centers were interviewed 1 year after injury. The interview included the SF-36 supplemented with four items chosen to assess cognitive function. Results The resulting cognitive function scale is internally consistent and measures a component of health that is independent of the dimensions incorporated in the SF-36. It correlates well with established measures of brain injury severity and discriminates among patients with and without brain injury. Conclusion This study underscores the need to supplement the SF-36 with a measure of cognitive function when evaluating outcome from multiple trauma involving head injury. Further studies are needed to validate the supecific items chosen for measuring cognitive function.
