Scientific reports·2026

This study found that impulsivity in suicidal behavior is complex, with neither the attempter's traits nor the attempt's state reliably predicting the other. Prevention requires monitoring suicidal ideation and intent.

Area of Science:

  • Psychiatry
  • Psychology
  • Behavioral Science

Background:

  • Impulsivity in suicidal behavior is conceptualized as both a trait of the individual and a state related to the attempt.
  • Previous research has not simultaneously examined these two facets of impulsivity in representative suicide attempt samples.

Purpose of the Study:

  • To investigate the relationship between attempter impulsivity (trait) and attempt impulsivity (state) in a sample of suicide attempts.
  • To compare continuous versus dichotomous measurement approaches for assessing impulsivity in suicidal behavior.

Main Methods:

  • A one-year prospective study involving 278 suicide attempts in a general hospital setting.
  • Utilized the Barratt Impulsiveness Scale to measure attempter impulsivity.
  • Assessed attempt impulsivity using the planning subscale of Beck's Suicidal Intent Scale.

Main Results:

  • Attempter impulsivity did not significantly predict attempt impulsivity, regardless of whether variables were treated as continuous or dichotomous.
  • Impulsive suicide attempts were associated with lower lethality and less severe depression.
  • Lack of depression and lower lethality were observed in impulsive attempts.

Conclusions:

  • The distinction between trait and state impulsivity is crucial for understanding suicidal behavior.
  • Effective suicide prevention strategies may involve monitoring suicidal ideation and intent, particularly in individuals with major depression or certain personality traits.
  • Further research is needed to clarify the interplay between different dimensions of impulsivity in suicide attempts.
