Background: To develop a Korean version of the QOLIE-31 and to confirm its psychometric properties.
Methods: The QOLIE-31 was adapted to Korean language through a translation-back translation procedure. Data were collected from 397 adult epilepsy patients. Patients were administered the Quality of Life in Epilepsy Inventory-31 (QOLIE-31), Korean Wechsler Intelligence Scale (KWIS), the Functional Assessment of Cancer Therapy-General (FACT-G), state scale of the State-Trait Anxiety Inventory (STAI), and the Center for Epidemiological Studies-Depression Scale (CES-D). We assessed internal consistency and test-retest reliabilities and construct validity.
Results: Cronbach’s alpha ranged from 0.69 to 0.86, and test-retest reliability was between 0.50 and 0.71, demonstrating that the items of OOLIE-31 are internally consistent and temporally stable. Pearson’s correlations among the QOLIE-31 and emotional well-being, state anxiety, and depressive symptoms were high. Most QOLIE-31 sub-scales discriminated well between patients according to seizure frequency, number of antiepileptic drugs, employment, economic status and depressive symptoms.
Conclusion: The Korean version of the QOLIE-31 was reliable, and showed construct validity comparable with the original U.S version. Results confirmed that the QOLIE-31 can be applied as one of the specific measures of quality of life in Korean epilepsy patients.
