Abstract

The aim of the current study was to identify personality traits associated with suicidal behavior in patients with depression. Of the 1183 patients screened for an observational cohort study of depression, 334 (28.2%) who completed the Temperament and Character Inventory (TCI) were included in these analyses. To minimize the effect of current mood state, the TCI was performed 12 weeks after initiation of treatment, and we adjusted for the severity of depression. Of the 344 participants, 59 had a lifetime history of at least one suicide attempt, 37 had a lifetime history of multiple suicide attempts, and 5 attempted suicide during the 12-week study period. At baseline, patients with a lifetime history of at least one suicide attempt, a lifetime history of multiple suicide attempts, and a suicide attempt during the study period expressed more serious current suicidal ideation than did those without such a history, despite the absence of differences among the groups in the severity of depressive and anxiety symptoms. Of the seven personality scales of the TCI, lower scores on the self-directedness scale of the character dimension were associated with a history of at least one suicide attempt (OR [95% CI], 0.91 [0.87-0.96]; p < 0.001), a history of multiple suicide attempts (0.91 [0.86-0.97]; p = 0.003), and suicide attempts during study period (0.80 [0.69-0.94]; p = 0.006). These findings suggest that depressed patients with a history of suicidal behavior differ from non-attempters with regard to personality traits, especially the character dimension of self-directedness. It is noteworthy that this result emerged after controlling for the effect of current mood state.
