Communicating Commitment: A Relationship-Protection Account of Dyadic Displays on Social Media.

People often make their romantic relationships visible to others through dyadic displays (DDs). Yet, their reasons for doing so are not well-understood. We proposed and tested a relationship-protection account of DD use, focusing on a social media environment. We predicted that relationship-protection motivation would predict DDs and that DDs would serve a relationship-protective function. In Study 1, a correlational study of romantically involved Facebook users, relationship-protection motivation positively predicted DD use on Facebook even when controlling for feelings of interconnectedness. Relationship-protection motivation also mediated effects of relationship satisfaction and commitment on DD use. In Study 2, participants perceived a target whose Facebook profile we experimentally manipulated to include DDs (vs. not) as more likely to be in a high-quality relationship and less receptive to romantic advances from others, with implications for participants' interest in affiliating with the target. Our findings support a relationship-protection account of DD use on social media.
