Psychobiological Concomitants of History of Suicide Attempts Among Violent Offenders and Impulsive Fire Setters

Arch Gen Psychiatry. 1989;46(7):604-606. doi:10.1001/archpsyc.1989.01810070030004

• Psychobiological data on 58 violent offenders and impulsive fire setters were analyzed for associations with history of suicide attempts. Subjects with a history of suicide attempts serious enough to require an admission to a medical facility had significantly lower mean cerebrospinal fluid 5-hydroxyindoleacetic acid and 3-methoxy-4-hydroxyphenylglycol concentrations than subjects who had not made such attempts. A linear discriminant function analysis based on psychobiological and behavioral variables correctly classified 79% of the subjects according to the suicide attempt history positive and negative outcomes.
