Is a prostate cancer screening anxiety measure invariant across two different samples of age-appropriate men?

Table 6 Measurement invariance for the two 1–factor anxiety models

	Chi–square (df)	P–value	CFI	TLI	RMSEA	WRMR
1–Factor PSA anxiety
1. less restrictive	13.052 (13)	.4438	1.00	1.00	.004	.560
2. more restrictive	34.804 (12)	.0005	.989	.988	.092	1.225
1. vs 2.	23.312 (4)	.0001
1–Factor PCS-D anxiety
1. less restrictive	14.206 (12)	.2878	.999	.999	.029	.577
2. more restrictive	23.553 (16)	.0997	.996	.997	.046	.833
1. vs 2.	9.554 (5)	.0889

Note. df = degrees of freedom; PSA = prostate–specific antigen test, DRE=digital rectal examination; PCS-D = prostate cancer screening decision; CFI = comparative fit index; TLI = Tucker–Lewis index; RMSEA = root mean square error of approximation; WRMR = weighted root mean square residual; bold font indicates adequate fit.
