Objective : To assess the validity and reliability of the QOLIE-31-Thai Version.
Materials and Methods : 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 con-
ducted. Its reliability was assessed using a sample of consenting epileptics aged 18-65 years visiting commu-
nity 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.
