t value: independent-sample test. r: the correlation coefficient of item and the total score.

It is divided into two groups according to the scores: a high mark group and a low mark group. 27% of the participants in high score sorted into the high score group, and 27% who got the low scores entered the low score group. ∗∗∗: P < 0.001, ∗∗: P < 0.01, ∗: P < 0.05.
