The association between the harm avoidance subscale of the Tridimensional Personality Questionnaire and serotonin transporter availability in the brainstem of male volunteers.

The relationship between harm avoidance scores of the Tridimensional Personality Questionnaire and serotonin transporter availability, as approximated using single photon emission computed tomography with [(123)I] ADAM, was examined. Our results showed a significant negative correlation between the harm avoidance total score, as well as the asthenia subscore, and serotonin transporter availability, particularly in males.
