When a romantic relationship ends in dissolution, the ex-partners may experience distress similar to post-traumatic stress or complex grief (i.e., dysphoric mood, feelings of loss, intrusive memories, negative rumination regarding the relationship, and a loss of self-esteem). Interventions designed to reduce post-breakup distress have historically attempted to foster integration of the breakup into the self-narrative through techniques such as expressive writing. Recent research indicates centrality, or heightened integration of an event or concept into an individual’s identity, predicts heightened levels of distress in the case of negative life events, including romantic relationship dissolution. Given the role romantic relationships themselves play in identity formation, exploration is warranted of the potential distress resulting from over-identification with a romantic relationship itself, or relationship centrality, after a breakup has occurred. Furthermore, if an individual has overly-integrated a relationship into their identity, the effectiveness of interventions focusing on further integration of the breakup is called into question. This study explored the centrality of participants’ previous romantic relationships, the distress resulting from the dissolution of those relationships, and the role of expressive writing as a distress reduction tool when centrality is taken into account.
