Abstract

To determine the factor structure of the Traumatic Brain Injury-Quality of Life (TBI-QOL) measurement system. Observational. 3 TBI Model Systems rehabilitation centers. Twenty TBI-QOL item banks were administered to a sample of community-dwelling adults with TBI (N=504) as part of a study of TBI classification. A subsample of participants (n=200) was randomly selected for exploratory factor analyses, while data from the remaining participants (n=304) were used for the confirmatory factor analysis. To examine a wide range of conceptual models, confirmatory factor analyses were conducted on a total of 16 models, ranging from 1 to 7 factors. Not applicable. Not applicable. Initial exploratory factor analysis yielded support for a 5-factor model (negative emotion, cognitive impairment, functioning and participation, positive emotion, pain). Confirmatory factor analysis results, however, indicated a 7-factor model including physical function, physical symptoms, cognition, negative emotion, positive emotion, sense of self, and social participation (model 16; robust fit statistics root mean square error of approximation =.063, standardized root mean square residual =.035, comparative fit index =.955, Tucker-Lewis Index =.943, Bayes In...Continue Reading
