Abstract

Impulsivity in suicidal behavior can describe the attempt (state) or the attempter (trait). There are no studies simultaneously measuring attempt impulsivity and attempter impulsivity in representative samples of suicide attempts. A one-year study of 278 suicide attempts in a general hospital tested the continuous versus dichotomous relationship between attempter impulsivity (Barratt Impulsiveness Scale) and attempt impulsivity (low scores in the planning subscale of Beck's Suicidal Intent Scale). Attempter impulsivity was not a good predictor of attempt impulsivity independently of how both dimensions were measured (continuous or dichotomous ways). Impulsive attempts were associated with low lethality and lack of depression. Opportunities for prevention of suicide attempts in major depression and some personality traits may exist but require attentive monitoring of suicidal ideation and intent.

Funding Information:
■ Acknowledgments The sample was recruited at the Hospital Ramon y Cajal, Madrid, Spain. The study was supported by a 1999 and 2001 National Alliance for Research on Schizophrenia and Depression (NARSAD) Young Investigator Awards and a grant from the Spanish Government (Fondo de Investigacion Sanitaria, FIS 01/0077-01). A description of the preliminary analysis was presented as a poster at the 56th Annual Meeting of the Society of Biological Psychiatry, New Orleans, LA, May 3–5, 2001. A reviewer challenged us by questioning our definition of attempt impulsivity; this led us to use a new definition and to make profound changes in the article.
