Area of Science:

  • Psychiatry
  • Psychology
  • Genetics

Background:

  • Bipolar disorder is a severe mental illness associated with an increased risk of suicide.
  • Understanding factors contributing to suicide attempts is crucial for prevention and treatment.

Purpose of the Study:

  • To investigate the influence of personality traits (temperament and character) on suicide attempts in individuals with bipolar disorder.
  • To identify specific personality dimensions and demographic factors associated with suicide attempts.

Main Methods:

  • A cohort of 100 euthymic bipolar patients (Types I and II) and 100 controls were assessed.
  • The Temperament and Character Inventory (TCI) was administered to evaluate personality dimensions.
  • Demographic data, age of onset, and family history of suicide were collected.

Main Results:

  • Patients with suicide attempts exhibited significantly higher harm avoidance (HA) and reward dependence.
  • Earlier age of onset was observed in bipolar patients with a history of suicide attempts.
  • Harm avoidance (HA) and psychasthenia (PS) were significantly correlated with suicide attempts, as were family history of suicide and gender.

Conclusions:

  • Personality traits, particularly harm avoidance (HA) and psychasthenia (PS), along with early age of onset, gender, and family history of suicide, are significant predictors of suicide attempts in bipolar disorder.
  • These findings highlight the importance of assessing personality and family history in the management of bipolar disorder to mitigate suicide risk.
