Indicators of homogeneity or internal consistency of the scale.

Items	Scale average if item is deleted	Scale variance if the item is deleted	Correlation between the item and the total if the item is deleted	Squared multiple correlation coefficient between the item and the rest of the items^*	Cronbach’s alpha if the item is deleted
P1 (daily chores)	16.82	279.337	0.768	0.771	0.942
P2 (family life)	17.11	272.692	0.839	0.850	0.934
P3 (professional life)	16.07	256.069	0.883	0.814	0.929
P4 (social life)	17.21	283.952	0.785	0.832	0.941
P5 (mental state)	15.50	261.148	0.880	0.815	0.929
P6 (relationship with caregivers	15.68	252.522	0.856	0.833	0.933
			Cronbach’s Alpha = 0.945 (95% confidence interval 0.906 to 0.971).

*Equivalent to the proportion of the item variance explained by the rest of the items.
