A trained interviewer and 5 Korean patients carried out cognitive debriefing.Results: Noun words such as "energy" and "responsibilities" were very difficult to translate to Korean. They were substituted by more comprehensive words. After backward translation, translated sentences showed a good agreement with the original WISQOL. During backward translation and the second reconciliation, previously translated Korean version was revised in 5 sentences. In the cognitive debriefing process, all 5 patients thought that these questions explained the patient's situation well. Most of these respondents answered that explanatory notes of questionnaire were well written and the format of the questionnaire was easy to follow.Conclusions: The present study demonstrated that, despite language differences, translation and linguistic validation of the KWISQOL were successfully performed. This K-WISQOL could be useful tools for treatment plan and patient care.
