Abstract

OXTR rs53576, a polymorphism on the oxytocin receptor gene, has previously been linked to individual differences in social behaviors. That is, individuals with the GG genotype show greater empathy, sociability, and emotional stability. In the context of close relationships, such psychological resources are associated with better relationship outcomes. However, no studies to our knowledge have examined associations between spouses' OXTR polymorphisms, attachment security, and marital satisfaction. In the current study, 178 married couples (N = 356; ages 37-90) completed self-report measures of attachment security and marital satisfaction and provided saliva samples for genotyping. Results from Actor Partner Interdependence Models showed that individuals who had the GG genotype (actor effect) or had a spouse with the GG genotype (partner effect) reported greater marital satisfaction than individuals with AA or AG genotypes. Furthermore, greater attachment security mediated associations between GG genotype and marital satisfaction.

  • Genetic polymorphisms in the human OXTR and AVP1RA genes have been linked to bonding and relationship outcomes.

    “Genetic polymorphisms in the human OXTR and AVP1RA genes have been linked to bonding and relationship outcomes.”

    From The Neurobiology of Love and Pair Bonding from Human and Animal Perspectives (2023) · cites this paper as [149]

    The Introduction (§ OXTR gene and romantic relationships) reports links between OXTR variants and partner bonding or relationship quality, and the Results report an association between OXTR rs53576 and marital satisfaction. Our copy does not report a link between AVP1RA polymorphisms and bonding or relationship outcomes; the reference mentioning vasopressin receptor 1a concerns empathy instead. (LLM, conf=0.88)

  • Women with the GG genotype of the rs53576 OXTR polymorphism display enhanced empathy, sociability, and emotional stability while also reporting greater marital satisfaction than those with the AA or AG genotype.

    “Women with the GG genotype of the rs53576 OXTR polymorphism display enhanced empathy, sociability, and emotional stability while also reporting greater marital satisfaction than those with the AA or AG genotype, suggesting genetic variations in OXTR expression may influence human social behavior [149].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
