The Thai version of the quality-of-life in epilepsy inventory (QOLIE-31-Thai version): translation, validity and reliability.

ABSTRACT

OBJECTIVE: To assess the validity and reliability of the QOLIE-31-Thai Version. MATERIAL AND METHOD: The original questionnaire of the QOLIE-31 was first translated into Thai and, then, item comprehension was assessed. Back translation into English and cross-cultural modification were conducted. Its reliability was assessed using a sample of consenting epileptics aged 18-65 years visiting community hospitals in Nakhon Ratchasima Province, Thailand. RESULTS: One hundred and sixty one epileptics completed the questionnaire. The internal consistency of each scale of the QOLIE-31 was above the accepted standard of 0.7, except for Cognitive Functioning, Medication Effect and Social Functioning. CONCLUSION: The QOLIE-31-Thai Version is reliable for use in Thai rural epileptics even for low educated epileptics but interviews might have to be used instead.
