How thinking and clinical features relate to suicide attempts in bipolar disorder: Can suicide be predicted?
Updated
Abstract
Patients who did not attempt suicide had significantly higher trait impulsivity scores compared to those who did.
- Nonattempters scored higher on the Barratt Impulsiveness Scale compared to attempters, with a significant difference (t(57) = 2.2, P = .03).
- Among attempters, lower trait impulsivity scores were associated with higher lethality of prior attempts (r(25) = -0.53, P = .01).
- No significant differences were found in demographic, clinical, or neurocognitive variables when comparing attempters and nonattempters.
- Regression models did not identify significant predictors of past suicide attempts.
- The study highlights challenges in predicting serious suicide attempts among bipolar disorder patients.
