abstract="The purpose of this study was to identify personality traits associated with suicide attempt in a clinical sample. Temperament and character inventory (TCI) profiles of 759 patients who met the inclusion criteria among 1000 randomly selected hospital records collected. Of these 759 patients, 103 had a history of at least 1 actual suicide attempt (suicidal group) whereas 656 had no such history (nonsuicidal group). The suicidal group showed higher scores of novelty seeking (mean ± SD: 36.1 ± 1.2 vs 33.3 ± 0.5; P =.026) and harm avoidance (57.1 ± 1.5 vs 53.0 ± 0.6; P =.01) but lower scores of self-directedness (27.5 ± 1.5 vs 34.4 ± 0.6; P <.001) than the nonsuicidal group. Higher novelty seeking (OR [95% CI]: 1.031 [1.008-1.054]; P =.007) and lower self-directedness: 0.955 [0.927-0.983]; P =.002 were also associated with suicide attempts in the analysis of 7 personality scales. These findings suggest that patients who attempt suicide differ from nonattempters in terms of personality traits, especially in novelty seeking (NS), harm avoidance (HA), and self-directedness (SD). It is noteworthy that this study contains data from actual visits to the emergency room to evaluate suicide attempts. Abbreviations: CO = cooperativeness, Ha = harm avoidance, NS = novelty seeking, PS = persistence, RD = reward dependence, SD = self-directedness, ST = self-transcendence, TCI = temperament and character inventory.<p /> <p>Language: en</p>",
