- Abstract
- Objective: Suicide is a major cause of death in university students. Personality traits have been suggested as possible risk factors for suicidal behaviors. This study looked at the relationship between the personality dimensions of the Temperament and Character Inventory (TCI) and suicidal behaviors. Method: A total of 5644 college students took the TCI test and the suicidality module of the M.I.N.I. The students were divided into the suicidal ideation group (n = 302; 5.4%) and the suicide attempt group (n = 301; 5.3%). Each group's TCI dimension and sub-dimension scores were compared with one another. To find out which TCI dimension affects suicide risk when depressed, regression analysis and mediation analysis were conducted. Results: First, we adjusted for age, sex and depressive mood and compared the TCI scores of the participants based on their suicide risk. After the adjustment, self-directedness decreased in the suicidal ideation group while novelty seeking and persistence increased in the suicide attempt group. It turned out that self-directedness has a partial mediating effect between depressive symptom and suicide risk (beta = -0.068 P < 0.001). Conclusion: We adjusted for depressive mood and it turned out that the suicidal ideation group is affected by character whereas the suicide attempt group is affected by temperament. Among the character dimensions, self-directedness was found to reduce the effect of depressive mood on suicide risk. Therefore, when evaluating suicide risk, assessing character dimensions, especially self-directedness along with depressive mood, a risk factor, will be helpful.
