Abstract:

Study assessed the factor structure of the Traumatic Brain Injury-Quality of Life (TBI-QOL) measurement system. Twenty TBI-QOL item banks were administered to a sample of 504 community-dwelling adults with TBI as part of a study of TBI classification. A subsample of 200 participants was randomly selected for exploratory factor analyses, while data from the remaining 304 participants 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. 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. The complex 7-factor model of the TBI-QOL provides a more nuanced framework for understanding health-related quality of life for people with TBI than the commonly used 3-factor model including physical health, mental health, and social health.
