Outif mean was 1.03 (SD = 0.54) with minimum value 0.67 and maximum of 1.90. Regarding people fit parameters, the infit mean was 1.02 (SD = 0.49) and outfit 1.03 (SD = 0.54). Items with higher loading in positive and negative dimension were selected. The correlation analysis between positive and negative items corrected by Spearman‑Brown form was r = 0.68.
