Related Data for: Association between Oxytocin Receptor Gene polymorphisms and number of followed people on Instagram: an exploratory analysis

So far the existing literature has considered the association between environmental factors, such as those involved in the relationship with people, and the correlates of genetic vulnerability (i.e. on the Oxytocin Receptor Gene) in the comprehension of social behavior. Although an extensive knowledge on in-person social interactions has been obtained, little is known about online social behavior. A gene-environment perspective is adopted to examine how Oxytocin Receptor Gene (OXTr) and adult attachment with a romantic partner interact in moderating Instagram users' behavior. The Experience in Close Relationships-Revised questionnaire was used to collect participants' (N = 57, 16 males) attachment pattern with the partner through the dimensions of anxiety and avoidance. The genetic factors within the regions rs53576 (A/A homozygotes vs. G-carriers) and rs2254298 (G/G homozygotes vs. A-carriers) of the Oxytocin Receptor Gene were assessed via buccal mucosa samples. Number of posts, followed people ("followings") and followers were obtained from Instagram, and the Social Desirability Index was calculated as the ratio of followers to followings. Interaction effects between genetic groups and ECR-R scores on the number of posts and SDI were hypothesised. Even though no interaction effects were observed, results showed a main effect of OXTr/rs53576 on the number of Instagram followings. Specifically, A/A homozygotes had a high number followings than G-carriers independently from the quality in the relationship with their partner. These preliminary results are discussed in light of the current debate of behavioral genetics and offer insights into future investigations on social media behavior.
