Validation of the McGill Quality of Life Questionnaire in home hospice settings in Israel.

Given that the meaning and significance of 'quality of life' can differ among language and cultural groups, it is incumbent upon researchers to assess whether the tool they have chosen is appropriate to the population under study. This study aimed to test the reliability and validity of the McGill Quality of Life Questionnaire (MQOL) translated into Hebrew for use with palliative care patients in Israel. In this, as in previous studies, the 16 questions of the tool clustered into four domains (physical, psychological, existential well-being and support), although the distribution of items among them differed somewhat. The existential well-being and psychological domains had an independent effect on the overall quality of life of patients in Israel, as in other countries. It seems that this tool produces similar responses in metastatic cancer patients around the world, and hence can be used to compare palliative care services in different countries.
