Objectives : To develop and test the reliability of a Thai version of the King’s Health Questionnaire (KHQ).
Materials and Methods : Three Thai Urologists forward translated the original English KHQ into a Thai
version. Back translations were performed by an independent group of physicians. A consensus was reached
on a final Thai version after comparing the original KHQ and various translations. Fifty Thai female patients
with symptoms of overactive bladder were tested and retested every two weeks using the Thai version (twice)
as well as the English version (once) of the KHQ. Test-retest reliability of the Thai questionnaire was measured
using the kappa statistic.
Results and
Conclusion : The Thai version of the KHQ was found to be reasonably reliable for use in Thai
female patients with over active bladder symptoms.
