Converging evidence indicates that a considerable amount of variance in self-estimated emotional competency can be directly attributed to genetic factors. The current study examined the associations between the polymorphisms of the Catechol-O-methyltransferase (COMT Met158Val) and the serotonin transporter (5-HTTLPR) and specific measures of the self-estimated effectiveness of an individual’s emotion perception and regulation. Emotional competence was measured in a large sample of 289 healthy women by using the Self-report Emotional Ability Scale (SEAS), which includes two subscales for the assessment of emotion perception and regulation in the intra-personal domain and two subscales for the assessment of emotion perception and regulation in the inter-personal domain. Participants’ reports of effective emotion regulation in everyday life were associated with the COMT Met-allele, with women homozygous for the Val-allele scoring lowest on this scale. Self-estimated effectiveness of emotion perception of the individual’s own emotions was related to the 5-HTTLPR. Both homozygous groups (s/s and l/l) rated their intra-personal emotion perception less effective than participants in the heterozygous s/l group. Taken together, the results indicate that genetic variants of the COMT and 5HTTLPR genes are differentially associated with specific measures of the self-estimated effectiveness of an individual’s emotion perception and regulation in the intra-personal domain.
