Abstract

This study deals with the psychophysiological (electrodermal reactivity in a habituation experiment, habituation score) basis of suicidal behaviour. It shows habituation data of 30 suicides with violent method compared to age- and sex-matched control groups with different suicidal expressions, on a large database of a total sample of 504 depressed inpatients. The major finding of a significantly reduced electrodermal reactivity (habituation score) in suicidal action versus suicidal thinking confirms early results but in a comprehensive large sample. Also, it confirms our clinical hypothesis of a biological basis of suicidal action, specially in suicidal acts with violent methods. © 1999 Kluwer Academic Publishers. All rights reserved.
