Abstract
We tested the hypothesis of an association between the serotonin transporter (5-HTT) gene regulatory region polymorphism and the Temperament and Character Inventory (TCI) personality dimension of Harm Avoidance. For the study, 124 subjects seeking inpatient treatment for primary alcohol dependence were grouped by their 5-HTT genotype and assessed with the TCI. Genotypes differed statistically significantly in Harm Avoidance but not in any other personality trait. This gives support to the hypothesis that the TCI temperament Harm Avoidance is associated with serotonergic neurotransmission in primary alcohol dependence.
