  1. Scale indicates the version of scale which we obtained the scale readings; * Indicates the item pairs were not the largest correlated pairs but exceeded ± .0.20; #1 indicates item 1 and so on; HFI indicates the item with highest item fit MNSQ; LFI indicates the item with lowest item fit MNSQ; 4pt indicates the 4 point-scale version; 1st indicates the 1st contrast in the PCAR and so on.
