Are suicide attempters who self-mutilate a unique population?

Area of Science:

• Psychiatry
• Clinical Psychology
• Behavioral Science

Background:

• Self-mutilation is associated with increased suicide risk.
• A clinical perception exists that self-mutilators' suicide attempts are attention-seeking rather than genuine.
• Understanding differences between suicide attempters with and without self-mutilation history is crucial.

Purpose of the Study:

• To identify distinct characteristics differentiating suicide attempters with a history of self-mutilation from those without.
• To investigate differences in psychopathology, attempt lethality, and behavioral patterns.

Main Methods:

• Comparative analysis of 30 self-mutilating suicide attempters and 23 non-self-mutilating suicide attempters, all with cluster B personality disorders.
• Assessment of demographic data, psychopathology, objective and perceived suicide attempt lethality, and suicidal behavior perceptions.

Main Results:

• No difference in objective suicide attempt lethality between groups.
• Self-mutilators perceived their attempts as less lethal with a higher likelihood of rescue.
• Self-mutilators exhibited higher depression, hopelessness, anxiety, impulsivity, suicide ideation, and childhood abuse history.

Conclusions:

• Suicide attempters with self-mutilation history are more depressed, anxious, and impulsive.
• They tend to underestimate the lethality of their suicide attempts.
• Clinicians may underestimate the suicide risk of self-mutilators due to these misperceptions.
