title: Harm avoidance and serotonin.
abstract: The relationships between the Tridimensional Personality Questionnaire (TPQ) and serotonergic activity has been described in some studies with controversial results. These studies have focused on specific patient populations rather than normal controls. Therefore, the aim of the present study is to examine the relationships between the TPQ and serotonergic activity in a group of non-patient subjects. Twenty-three normal subjects answered the TPQ, and the serotonergic activity was assessed by the prolactin response to a highly potent and selective 5-HT1a agonist (flesinoxan). A positive relationship between harm avoidance and PRL response to flesinoxan was found. This study is consistent with the hypothesized link between serotonergic activity and the harm avoidance dimension of the biosocial model of Cloninger.
