Significant components of the Palliative Care Outcome Scale identified by principal component analysis (N = 504), and comparison of components with eigenvalues >1 with significant components identified by Horn’s parallel analysis

Component	PCA: initial eigenvalues			Horn’s parallel analysis: significant mean eigenvalues (SD)
	Total	% of variance	Cumulative %
1	2.908	29.080	32.807	1.2609	(0.0359)
2	1.269	12.693	41.773	1.1833	(0.0355)
3	1.013	10.128	51.901	1.1134	(0.0242)

Bold formatting indicates the significant eigenvalue levels identified using each approach
