Validation of the Korean version of the McMaster Quality of Life Scale in terminal cancer patients.

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.
