Abstract

The goal of the present study was to test the reliability and validity of the Japanese version of the Quality of Life after Brain Injury (QOLIBRI) scale. Correlations between the QOLIBRI and Glasgow Coma Scale scores, anxiety, depression, general quality of life (QOL), and demographic characteristics were examined to assess scale validity. The structure of the QOLIBRI was investigated with exploratory and confirmatory factor analyses, as well as the Partial Credit Model. Test-retest reliability was assessed over a 2-week interval. Participants were 129 patients with traumatic brain injury (TBI) recruited from rehabilitation centers in Japan. The QOLIBRI showed good-to-excellent internal consistency (Cronbach's α: 0.82-0.96), test-retest reliability, and validity (r = 0.77-0.90). Factor analyses revealed a 6-factor structure. Compared to an international sample (IS), Japanese patients had lower QOLIBRI scores and lower satisfaction in several domains. There were positive correlations between the QOLIBRI scales and the Short Form 36 Health Survey (r = 0.22-0.41). The Japanese version of the QOLIBRI showed good-to-excellent psychometric properties. Differences between JS and IS may reflect sampling bias and cultural norms regarding self-evaluation. The QOLIBRI could be a useful tool for assessing health-related QOL in individuals with TBI.
