N2 - This study analyzed the linguistic and psychometric validation of the Japanese version of the Quality of Life after Brain Injury-Overall Scale (QOLIBRI-OS) consisting of six items which cover several TBI-relevant domains. We hypothesized that the Japanese version has good reliability, convergent validity, and divergent validity, compared with its long version, the 37-item QOLIBRI. The QOLIBRI-OS Japanese version was forward and back-translated from the English version. In total, 129 individuals participated in this study after experiencing a traumatic brain injury and attending clinics, rehabilitation centers, and support centers in Japan. The structure of the QOLIBRI-OS was investigated by confirmatory factor analyses and compared with the QOLIBRI. Only one factor was extracted, and a model with one underlying factor had a good fit. The QOLIBRI-OS showed good-to-excellent internal consistency and test-retest reliability. The QOLIBRI-OS was positively correlated with the QOLIBRI, Short Form Health Survey-36 version 2, and Glasgow Outcome Scale Extended, and negatively correlated with the Hospital Anxiety and Depression Scale. The results suggest that the QOLIBRI-OS Japanese version is a reliable and valid tool for assessing disease-specific health-related QOL in individuals after traumatic brain injury in Japan.
