 NOTES: DF = degrees of freedom; 6F mod = 6factor model; 5F mod = 5factor model; 4d mod = 4domain model; 6d mod = 6domain model; GFI = goodness of fit index; FI = fit index; RMSEA = root mean square error; AIC = Akaike index; Gen popn = general population
 * Ideal fit indices are: Discrepancy/Df < 5; GFI, AGFI ≥ 0.9; RMSEA = 0.05 – 0.08; lower AIC
