^aThe fitting indices were as follows: χ²/df=2.1, adjusted goodness-of-fit index (AGFI)=0.858, goodness-of-fit index (GFI)=0.893, comparative fit index (CFI)=0.935, and root mean square error of approximation (RMSEA)=0.063.

^bN/A: not applicable; average variance extracted was calculated for each dimension, not for each item.
