Meaning in life and quality of life: comparison between palliative care patients and a representative sample of the Swiss population

Background and objectives Existential areas, and in particular the concept of meaning in life, represent a key topic in palliative care. The aims of this study are to explore (i) the differences in perceived meaning in life (MIL) and in the meaning-relevant life areas between a representative sample of the Swiss population and palliative care patients, and (ii) to what extent MIL can be considered as a significant predictor of quality of life (QOL) in the two populations.

Results indicated high MIL scores in both population even if the difference was significant (patients 81.9 vs general population 87, p
