The Korean version of the University of Washington Quality of Life Questionnaire for Patients with head and neck cancer, and its use in an initial validation study of 56 patients.
The University of Washington Quality of Life (UW-QOL) questionnaire is often used to assess health-related quality of life (HRQOL) of head and neck cancer patients. The aim of this study was to translate the UW-QOL version 4 into the Korean language and to carry out an initial validation study. A recognized methodology for translation of questionnaires was used. The validation study used the final Korean version between March and September 2009. Adult patients were recruited, with a confirmed diagnosis of head and neck cancer, therapy completed and disease-free for at least 1 year. The UW-QOL was successfully translated into Korean. 56 patients completed Korean versions of UW-QOL, the Beck Depression Inventory and the World Health Organization Quality of Life-BREF and various expected correlations were confirmed first between the two UW-QOL subscales (Spearman 0.54 p<0.001) and then of these subscales with the other concurrent measures. Lower (worse) UW-QOL scores were seen for later stage patients in all 12 domains. The Korean version of UW-QOL is ready for use in the assessment of HRQOL for Korean patients. Validation work needs to be continued to further establish psychometric properties of the questionnaire for use in this population.
