MAiD = Medical assistance in dying; NDPC = Natural death assisted by palliative care; RGEI = Revised grief experience inventory; PG-13 = Prolonged Grief-13; ANCOVA = Analysis of covariance.

^aScale range refers to minimum and maximum scores. Higher scores on the PG-13 and RGEI global score indicate greater grief distress/intensity. Higher scores on the RGEI subscales indicate that these grief dimensions are more problematic for the individual.

^bThe cut-off score for Prolonged Grief Disorder’s diagnosis proposed by Pohlkamp and colleagues (2018) is 35.
