χ2 (df) chi-square test (degrees of freedom); RMSEA root mean square error of approximation (< 0.05 = good fit and upper CI < 0.08); SRMR standardized root mean square residual (< 0.05 = good fit and < 0.08 = adequate fit); CFI Comparative Fit Index (> 0.95 = good fit and > 0.90 = adequate fit); TLI Tucker-Lewis Index (> 0.95 = good fit and > 0.90 = adequate fit)
