Abstract

Objective: To examine the associations between personality traits and suicidal ideation (SI) and attempt (SA) in mood disorder patients and community controls. Method: We recruited 365 bipolar, 296 major depressive disorder patients, and 315 community controls to assess their lifetime suicidality. Participants filled out self-reported personality questionnaires to collect data of personality traits, including novelty seeking (NS), harm avoidance (HA), extraversion (E), and neuroticism (N). We used logistic regression models adjusted for diagnoses to analyze combinational effects of personality traits on the risk of suicide. Additionally, radar charts display personality profiles for suicidal behaviours by groups. Results: All personality traits were associated with the risk of suicidality with various effect size, except for E that showed protective effect. High N or HA had prominent and independent risk effects on SI and SA. Combinations of high N and low E, or high HA and NS were the risk personality profiles for suicidality. Higher N scores further distinguished SA from SI in mood disorder patients. Conclusion: Introvert personality traits showed independent risk effects on suicidality regardless of diagnosis status. Among high-risk individuals with suicidal thoughts, higher neuroticism tendency is further associated with increased risk of suicide attempt.
