OXTR and Anxiety: Gene*environment interaction on the Eastern sample: We expected to observe a statistically significant effect of the interaction between OXTR polymorphism and parental bonding features (assessed using the PBI scales) over the main features of adult social relationships (measured with the ECR-R), with Singaporean G-carriers exhibiting different rates of distress in terms of anxiety and avoidance than A/A homozygotes when they recalled low levels of parental care and high levels of parental overprotection.
