Abstract

Background: The QOLIBRI–Quality of Life after Brain Injury questionnaire was developed by the QOLIBRI Task Force (QTF). Our goal was to investigate the applicability, validity and reliability of the QOLIBRI in Israel. Methods: Validation of the Hebrew questionnaire was performed after it had been administered to 128 adults with traumatic brain injury (TBI), who were between 3 months’ and 15 years’ post-discharge from rehabilitation. Results: The internal consistency of the QOLIBRI subscales with the QOLIBRI Total scale was high (Cronbach’s α = 0.92); the same was true regarding the correlations between each QOLIBRI subscale and its own items (α = 0.92–0.95). Significant and high Pearson’s and Spearman’s correlations of the QOLIBRI subscales with demographic and clinical characteristics of the GOSE, ADL, HADS, SF-36, and various aspects of self-reported health status were found. Factor analyses (FA) were applied to confirm the validity of the Hebrew version, using the maximum likelihood method. The six subscales explained 100% of the variance. Conclusion: The Hebrew version of the QOLIBRI was found to be useful, meaningful and meeting psychometric criteria in persons after TBI in Israel. The findings support the cross-cultural applicability of the QOLIBRI, regardless of cultural and social differences.
