| Summary: | Background: Patients with Traumatic Brain Injury (TBI) often experience various complications following their injuries, which can significantly affect their quality of life. The Quality of Life after Brain Injury (QOLIBRI) questionnaire is a validated English questionnaire designed to assess the quality of life in TBI patients.Objectives: The present study was conducted to translate and validate a Persian version of the QOLIBRI questionnaire for the Iranian culture.Methods: Translation and cross-cultural adaptation of the QOLIBRI questionnaire were carried out according to guidelines provided by the QOLIBRI Task Force (QTF) team. Two hundred patients with TBI filled out the Persian version of the QOLIBRI, along with the Persian versions of HADS (Hospital Anxiety and Depression Survey) and SF-12 (Short Form-12) questionnaires, as well as a 29-item health status form. We also collected clinical and demographic data and reported descriptive statistics, Cronbach’s alpha for internal consistency, and Spearman’s correlation for concurrent validity. After a three-week interval, 30 patients completed the questionnaire again to assess test-retest reliability.Results: Some modifications were made to the QOLIBRI questionnaire to improve its readability and cultural compatibility. The mean total QOLIBRI score was 56.2 (SD=20.4). QOLIBRI scores did not significantly differ by gender or marital status; however, a significant difference was found among various occupational groups. The test-retest reliability demonstrated strong stability (ICC=0.9), and the internal consistency for both the total and subscales was found to be high, with a Cronbach’s alpha of 0.90. Correlations between QOLIBRI scores and SF-12 subscales (MCS and PCS) were statistically significant. Furthermore, negative correlations with depression and the number of comorbidities, along with high intercorrelations among QOLIBRI subscales, further supported the scale's validity.Conclusion: This study indicates that the Persian version of QOLIBRI is a valid and reliable tool for assessing the quality of life in TBI patients. |
