Abstract

Little research has been conducted towards the development and evaluation of a measure of quality of life specific to head/brain injury populations. Accordingly, we examined responses to the Neurobehavioral Functioning Inventory in the context of a clinical trial for head injury patients (n = 655) conducted in 14 countries. To reduce the 66 item scale into a smaller number of composite scales, principal components analysis was conducted. Scales were constructed assessing four categories of symptoms: cognitive deficits, depression, aggression and somatization. The internal reliabilities (alpha coefficient) of the four scales were generally acceptable (range = 0.79-0.92). Scores on all four scales correlated significantly with patient-rated overall quality of life and all but the aggression scale correlated significantly with overall clinical severity. The need for more formal evaluation of this and other disease-specific measures is discussed.
