ContextThe European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 15-Palliative Care (EORTC QLQ-C15-PAL) is a shortened version of the EORTC QLQ-C30, developed for use in advanced cancer patients.ObjectivesWe evaluated the psychometric properties of the Korean version of the EORTC QLQ-C15-PAL to determine if this tool can be used to evaluate Korean patients with cancer who receive palliative care.MethodsA multicenter, cross-sectional survey was performed in palliative care units and hospices in Korea from September to October 2009. A total of 102 patients with cancer completed the questionnaires that included the EORTC QLQ-C15-PAL.ResultsThe compliance rate was high, with the missing rate for each item ranging from 0% to 7.8% (mean 3.1%). A multitrait scaling analysis revealed good convergent and discriminant validity, with only three scaling errors. The Cronbach's alpha coefficients ranged from 0.65 to 0.89. The questionnaire discriminated among patient subgroups with different clinical profiles (e.g., performance status and degree of oral intake), thereby demonstrating the clinical validity of this tool.ConclusionOur findings indicate that the Korean version of the EORTC QLQ-C15-PAL is a reliable and valid instrument with regard to its psychometric properties. This tool is suitable for measuring quality of life, particularly with regard to physical aspects, in Korean cancer patients who receive palliative care.Copyright © 2011 U.S. Cancer Pain Relief Committee.
