Abstract

The Eysenck Personality Questionnaire (EPQ) and scales purporting to measure sensation seeking, impulsivity and introversion-schizoidia, and scales related to aggressivity from two personality inventories, the Karolinska Scales of Personality (KSP) and the Eysenck Impulsiveness- Venturesomeness-Empathy (IVE) inventory were given to 58 male subjects. Monoamine oxidase (MAO) activity was measured in platelets. The two sensation seeking scales were not associated with platelet MAO activity in the present subjects. The two impulsivity scales (IVE Impulsiveness and KSP Impulsiveness) and the KSP Irritability scale (an aggressivity-related scale) were negatively correlated with platelet MAO activity. Subgroups classified on the basis of platelet MAO activity differed in IVE Impulsiveness, KSP Detachment (introversion-schizoidia) and in KSP Irritability, low MAO subjects scoring higher in Impulsiveness and Irritability and high MAO subjects higher in Detachment. There were striking differences between the low MAO subgroup and the other subgroups in the percentage agreement responses in items of the IVE Impulsiveness scale, as well as in self-rated anger-proneness.
