(1)Spearman correlation coefficient. Symbols indicate level of significance: * 𝑃 < 0 . 0 5 ; ** 𝑃 < 0 . 0 1 ; *** 𝑃 < 0 . 0 0 1 .
(2)1 = when the cut-off point of the GHQ-12 was 3/4, those who scored 4 or more; 0 = those who scored 3 or less.
(3)1 = those who are scored in the upper 30th percentile; 0 = others.
(4)Affective temperaments assessed by the TEMPS-A.
