  1. Results are based on the original DSM-5 structure of PTSD12. When the use of the response range was limited, item categories were collapsed. MI models are increasingly restricted and nested. The previous model always serves as a reference. CFA confirmatory factor analysis, CFI comparative fit index, ΔCFI, difference in CFI; CI confidence interval, df degrees of freedom; Δdf, difference in df; p statistical significance of χ2, Δp, statistical significance of Δχ2; RMSEA root mean square of approximation; ΔRMSEA, difference in RMSEA; SRMR standard root mean square residual; ΔSRMR, difference in SRMR; TLI Tucker-Lewis index; ΔTLI, difference in TLI; χ2, overall scaled chi-square statistic; Δχ2, scaled chi-square difference statistic.
