title: Validity and reliability of the Portuguese version of the quality of life in epilepsy inventory (QOLIE-31) for Brazil.
abstract: OBJECTIVE
  We report the cultural adaptation and psychometric properties of the Quality of Life in Epilepsy-31 Inventory (QOLIE-31) for the Portuguese language and Brazilian culture.
  
  
  METHODS
  This study involved 150 outpatients: 50 presurgical patients with refractory temporal lobe epilepsy (TLE) related to mesial temporal sclerosis (MTS), 50 patients with juvenile myoclonic epilepsy (JME), and 50 seizure-free patients with TLE. They completed the QOLIE-31, Nottingham Health Profile (NHP), Beck Depression Inventory (BDI), and Adverse Events Profile (AEP) and underwent a neuropsychological evaluation (NE). Internal consistency reliability, interrater and test-retest reliability, and construct validity were assessed.
  
  
  RESULTS
  QOLIE-31 mean scores were 33.1 (Social Function), 68.9 (Overall Quality of Life), 56.5 (Seizure Worry), 64.1 (Emotional Well-Being), 63.7 (Energy/Fatigue), 38.9 (Cognitive Function), and 49.7 (Medication Effects). Internal consistency was high (Cronbach's alpha), as were the associations between QOLIE-31 and the BDI, NHP, AEP, and NE.
  
  
  CONCLUSIONS
  The Portuguese/Brazilian version of the QOLIE-31 inventory showed good reliability, validity, and construct validity.
