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.
