Personality disorders, particularly explosive types, are common after suicide attempts, especially in men. However, personality traits alone do not predict suicide intent when depression severity is controlled, though they interact with age.

Area of Science:

  • Psychiatry
  • Psychology
  • Behavioral Sciences

Background:

  • Suicide intent is linked to attempt seriousness and personality traits.
  • Understanding personality's role in suicide attempts is crucial for intervention.

Purpose of the Study:

  • To investigate the relationship between personality disorders, depression, and suicide intent in patients following a parasuicide.
  • To examine gender differences in personality traits and their association with suicide intent.

Main Methods:

  • Assessed 60 patients post-parasuicide using measures of depression, suicide intent, and personality.
  • Utilized both categorical and dimensional approaches to personality assessment.
  • Controlled for depression severity in correlational analyses.

Main Results:

  • Over 65% of patients exhibited personality disorder, predominantly of the explosive type.
  • Personality disorder was more prevalent in men; sociopathy dimension linked to male gender.
  • No significant correlation found between personality measures (dimensional or categorical) and suicide intent when depression was controlled.
  • Personality did not significantly predict intent variance independently but interacted significantly with age.

Conclusions:

  • While personality disorders are common in parasuicide patients, they do not independently predict suicide intent when depression is accounted for.
  • The interaction between personality and age may be a significant factor in determining suicide intent.
  • Further research is needed to elucidate the complex interplay of personality, depression, age, and suicide intent.
