marginally significantP ≥ 0.05
The Wald tests of parameter constraints with 1 degree of freedom indicate that constraining the unstandardized b coefficients or residual variances to be equal led to statistically significant loss of fit (χ 2 ≥ 3.86, P < 0.05) in 5 comparisons and marginally significant loss of fit ( P ≥ 0.05, <0.10) in 4 comparisons.
