Personality correlates of platelet monoamine oxidase (MAO) activity in female and male subjects.
Associations between platelet monoamine oxidase (MAO) activity and scale scores from the Eysenck Personality Questionnaire, the Impulsiveness-Venturesomeness-Empathy inventory and the Karolinska Scales of Personality were studied in 32 female and 29 male students (age range 17-19 years). There were significant negative correlations between MAO activity and extraversion-related scales for male subjects; in the female group the correlations were also negative but nonsignificant. When comparing subgroups with low, intermediate, and high platelet MAO activity subjects, consistent trends were observed in the direction of higher scores in the impulsivity scales, the sensation seeking-related Monotony avoidance scale, and the Indirect Aggression scale for both female and male low MAO activity groups.
