Differentiating suicide attempters from suicidal ideators: Differences between major depressive and bipolar...

Area of Science:

• Psychiatry
• Psychology
• Mental Health Research

Background:

• Identifying psychological variables is crucial for distinguishing suicide attempters from those with suicidal ideations.
• Understanding these differences is key for effective suicide prevention strategies.

Purpose of the Study:

• To investigate differences between major depressive disorder (MDD) and bipolar disorder (BD) in the progression from suicidal ideations to suicide attempts.
• To apply the ideation-to-action framework to understand suicide risk in these patient groups.

Main Methods:

• Assessed outpatients with MDD and BD using self-report questionnaires for suicidal history, schemas, personality features, maltreatment, and interpersonal-psychological factors.
• Utilized independent t-tests and multivariable logistic regression to identify differentiating factors between suicidal ideations (SIs) and suicide attempts (SAs).

Main Results:

• In MDD patients, factors included specific maladaptive schemas, self-harm, childhood emotional abuse, perceived burdensomeness, and fearlessness about death.
• In BD patients, factors included multiple schemas, borderline personality features, childhood physical/sexual abuse, and perceived burdensomeness.

Conclusions:

• Distinct psychological factors differentiate suicide attempts from ideations in MDD versus BD patients.
• Emphasizes the importance of considering diagnostic differences within the ideation-to-action framework for suicide risk assessment.
• Recommends future prospective research to validate these differentiating factors for suicide risk prediction.
