S-B χ 2 = Sattora-Bentler χ 2. CFI = comparative fit index. TLI = Tucker Lewis Index. RMSEA = root mean square of approximation. SRMR = standardized root mean square residual. BIC = Bayesian information criterion. S-B Δχ 2 = Sattora-Bentler χ 2 difference test. PTG = posttraumatic growth. PTSD-R = posttraumatic stress disorder reexperiencing symptoms.
