柯氏以習慣為關鍵概念，將「心理健康」定義爲「良好習慣多，不良習慣少的心態謂之健康；而良好習慣少，不良習慣多的心態，謂之不健康」。本文之目的旨在驗證上述的心理健康定義，以柯氏性格量表（1985）測量試者的心理健康狀態，並自編一套思考習慣問卷，這兩套量表都有積極與消極兩項分數。研究結果指出，良好的思考習慣分數與健康分數成顯著正向關係，但與不健康分數成顯著負向關係；定義。而不良的思習考慣分數分別與健康及不健康分數成顯著負向及正向關係，支持了柯氏的心理健康在討論部分本文討論社會讚許分數對於習慣與心理健康的關係可能造成的混淆作用，並建議在將來的研究裏，編製多向度的習慣問卷，俾能更提高習慣與心理健問的關係。

The purpose of the present study is to test the hypothesis proposed by Ko for mental health, which states that condition of mental health of a person is significantly related in positive and negative way respectively to the good and bad habits he has. Subjects were given the Ko's mental health questionnaire (1985) and a thinking habits scale. Each questionnaire consists of positive and negative score. Results indicate the scores of good thinking habits have sigifnicant positive correlation with positive mental health score, but have negative correlation with negative mental health score. Reversely, the scores of bad thinking habits have. significant negative correlation with positive mental health, but have positive correlation with negative mental health. All results support Ko's hypothesis for mental health. In Discussion, it was proposed that the factor of social desirability is eliminated before computing the relation between mental health and good or bad habits. In the future, we can design a multi-dimensional habit questionnaire in benefit of raising the relationship of habits and mental health.
