  1. CFI Comparative Fit Index. TLI Tucker-Lewis Index. RMSEA Root Mean Square Error of Approximation. SRMR Standardized Root Mean Square Residual. The models with collapsed categories were analysed with the two lowest (worst scoring) categories merged into one, including the same modifications as the models with correlated residuals
