The purpose of this study was to develop and validate a Korean version of McMaster Quality of Life Scale (K-MQLS) suitable for evaluating clinical hospice and palliative care. The McMaster Quality of Life Scale (MQLS) is a brief and comprehensive scale that is used to assess cancer patients receiving palliative care due to poor physical condition. To further develop the K-MQLS, we followed rigorous international translation steps and performed validity, reliability, and sensitivity analyses. The results of our study show that the K-MQLS is an efficient tool in terms of its validity, reliability, and sensitivity for the measurement of the health-related quality of life during the palliative phase. This developed tool could be used in research or clinical settings to assess health-related quality of life in Korean palliative care patients.
