Suicidal individuals often exhibit lower academic achievement, smoking habits, and psychiatric issues. Aggressiveness and depression scores were elevated in both suicide and accidental death groups compared to controls.

Area of Science:

  • Psychiatry
  • Psychology
  • Criminology

Background:

  • Suicide and accidental deaths represent significant public health concerns.
  • Understanding the psychological and social precursors to these outcomes is crucial for prevention.

Purpose of the Study:

  • To investigate personality factors and social characteristics associated with suicide and accidental deaths.
  • To examine these factors from adolescence into adulthood.

Main Methods:

  • Analysis of a random sample of Swiss army conscripts (28 suicide, 36 accidental deaths, 2754 controls).
  • Assessment of social, psychological, and personality features at age 19.
  • Longitudinal follow-up data collected until age 36.

Main Results:

  • Suicide cases showed higher rates of low school achievement, smoking, and psychiatric disorders.
  • Elevated scores for aggressiveness (excitability, reactive, spontaneous) and depression were observed in both suicide and accidental death groups compared to controls.
  • Findings suggest impulsiveness may play a role in suicide.

Conclusions:

  • Specific personality traits and social factors are linked to increased risk of suicide and accidental death.
  • Aggressiveness and depression are significant indicators in both fatal outcomes.
  • Results align with existing research and biological theories on impulsivity and suicide.
