ABSTRAKT:OBJECTIVES: The aim of our study was to investigate whether genetic variations in the Arginine vasopressin Receptor 1A (AVPR1A) gene or the presence of a child is associated with couple satisfaction. METHODS: A total of 53 healthy volunteers (32 women) participated in this study. The average age was 28.7 years (SD = 8.7). All participants were required to have a relationship of at least one year with their partner. The RS3 microsatellite in the AVPR1A promoter region was genotyped. The couple satisfaction was evaluated by Couple Satisfaction Index questionnaire. RESULTS: It was shown that the variability of the AVPR1A gene was not associated with couple satisfaction (p = 0.114), but childless participants had a higher level of couple satisfaction than those with children (p = 0.032, Cohen’s d = 0.735). CONCLUSION: However, it cannot be considered a causal relationship, these findings indicate the importance of non-genetic factors in the context of partner satisfaction. Our results suggest a link between the presence of a child and the quality of a partnership and attachment. This observation could have implications for behavioral research, as well as for awareness programs, education, and support services for parents.
