Based on the univariate χ² incremental values (p < 0.05)
a: The cut-off points of model fit: CFI greater than .90, Changes in CFI equal or less than 0.01, the point estimate of RMSEA less than 0.05 and the 90%CI of RMSEA less than 0.08, SRMR less than 0.08.
b: Equality constraints related to item Enjoy3 and item Comp3 were removed sequentially
