RMSEA = Root mean square error of approximation; 90% CI = Upper and lower bounds for the RMSEA; SRMR = Standardized root mean square residual; CFI = Comparative Fit Index. Probability values are adjusted for multivariate non-normality using Bollen-Stine corrections from bootstrapping with 10,000 samples.
