Objective: the purpose of this article was to report the translation of the Quality of Life in Epilepsy Inventory-89 (QOLIE-89) into a Portuguese-Brazilian version and evaluate its reliability and validity.Methods: This study involved 105 Outpatients: 54 patients with refractory temporal lobe epilepsy (TLE) with mesial temporal sclerosis (MTS) and 51 with juvenile myoclonic epilepsy (JME). Reliability and test-retest reliability were assessed. Relationships between QOLIE-89 domains and other questionnaires (Nottingham Health Profile, Beck Depression Inventory, Adverse Event Profile, Neuropsychological Evaluation), and external measures such as demographic and clinical variables were analyzed to examine construct validity.Results: Internal consistency (Cronbach's alpha = 0.73-0.92) and test-retest reliability (intraclass correlation coefficient = 0.60-0.84) for individual domains were acceptable. for construct validity, we verified high correlations between the QOLIE-89 and the Nottingham Health Profile, Beck Depression Inventory, Adverse Event Profile, and Neuropsychological Evaluation. for clinical characteristics, the patients with juvenile myoclonic epilepsy had better quality-of-life scores on 11 of 17 QOLIE-89 subscales compared with patients with temporal lobe epilepsy (P < 0.05).Conclusion: These results Support the reliability and validity of the Portuguese-Brazilian translation of QOLIE-89.
