  1. aThe interpretation of χ2-values is not meaningful because the WLSMV estimator for categorical indicators was used. Therefore, the model-comparison test implemented in Mplus software (DIFFTEST) was used
  2. bThese values refer to corrected χ2 values, provided in the output of the DIFFTEST implemented in Mplus
