  1. Notes: df = degree of freedom; 4F model = 4-factor model; 6F model = 6-factor model; CFI = Comparative fit index; RMSEA = root mean square error; AIC = Akaike index. Ideal fit indices are nonsignificant discrepancy (p > .05), relative chi-square < 3, CFI > .9, RMSEA ≦ .08, lower AIC.
  2. * p < .001.
