Validation study of the Korean version of the McGill Quality of Life Questionnaire.
This study aimed to test the reliability and validity of the Korean version of McGill Quality of Life Questionnaire (MQOL-K) for use with 140 palliative care patients in Korea. Our results confirmed the suitability of using the 16 questions of the questionnaire clustered into four domains (physical, psychological, existential and support) as in the original version of the MQOL, although the distribution of items among the domains differed somewhat from the original. The MQOL-K demonstrated moderate to high internal consistency (Cronbach's alpha, 0.62-0.90), convergent validity without scaling error, and a good concurrent validity with European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30, sense of dignity, and general health perception. In addition, we tested the clinical validity of the MQOL-K using a known group comparison to quantify sensitivity. Regression results indicated that the existential and psychological domains had independent effects on the overall quality of life of patients in Korea. Therefore, the MQOL-K is deemed suitable for assessing the quality of life in a Korean palliative care setting.
