Happiness is an issue on college campuses because college is a time of transition to adult and professional life. In particular, nursing college students feel an excessive burden on patient care and relationships with medical staff in heavy academic stress and clinical practice at universities, causing psychological disorders such as tension, anxiety, depression, etc. due to these problems. The purpose of this study is to identify the temperament and personality types of nursing college students and to identify the factors that affect each type of subjective happiness.

The research method used TCI-RS to identify the temperament and character, and subjective happiness was measured using Oxford’s happiness sensitivity tool. The statistical methods utilized the methods of technical statistics, ANOVA, and multiplicity.

The percent of below 30 percentile of self-transcendence (ST) and persistence (P) were 48.4%, 43.7% whereas The percent of above 70percentile correspondence (CO), self-directedness+cooperativeness (SC), and reward dependence (RD) were 50.7%, 49.3%, 39.0%. Factors affecting the subjective happiness of nursing college students are harm avoidance (HA) (β=−.16), p＜.001), RD (β=27, p＜.001), self-directedness (SD) (β=.59, p＜.001) and 69% explained. Nursing college students had higher subjective happiness as autonomous students and higher social sensitivity. In comparison, the lower the hedging tendency, the higher subjective happiness.

To enhance subjective happiness of nursing college students, arbitration seems to be necessary considering the temperament and character of individual students.
