Exploring romantic relationships on social networking sites using the self-expansion model

Several hypotheses were derived from the self-expansion model (Aron & Aron, 1986) concerning romantic relationships and social networking sites (SNSs). A sample of 276 participants responded to questions about their relationship history and SNS uses and a subset of those (N = 149) responded to additional questions about a current romantic partner. Results suggest that past self-expansion leaves a residue shown by more interests. This finding was moderated by overall Facebook use. Particular Facebook behaviors such as tagging one’s partner in status updates, appearing together in photographs, and listing similar interests on profiles are indicative of self-expansion processes typically found in romantic relationships.

► Tagging romantic partners in posts on SNSs positively affect relationships. ► Appearing in photos together on SNSs positively affect relationships. ► Self-expansion model expanded to include effects of past relationships. ► Overall SNS use can a moderator of the effect of SNS use on relationships.
