	χ2	df	CFI	RMSEA
1 factor	829.28	107	0.78	0.064
3 factors	578.63	89	0.85	0.058
4 factors (Stefanis et al.17)	632.44	106	0.84	0.055
4 factors (Yung et al.15)	590.88	106	0.85	0.053
5 factors	352.28	105	0.92	0.038

Note: Note that Yung and colleagues¹⁵ used 18 of 20 positive Community Assessment of Psychic Experiences items for the 3-factor model; therefore, the df is lower in this model. CFI, Comparative Fit Index; RMSEA, Root Mean Square Error of Approximation.
