The termination of a romantic relationship, be it by breakup or divorce, is a fairly ubiquitous experience. Most individuals will recover from a traumatic experience of this nature; some however, experience substantial difficulties in recuperating that persist over time. For these individuals, relationship termination can invoke a variety of negative physical and psychological health outcomes. This project examines the role of social cognitive maturity, operationalized as Interpersonal Decentering, in recovery following a relational loss. Participants in this study were assigned to a pre/post control or measurement intensive (four visits) condition over the course of nine weeks. Individuals in the latter condition completed a Stream of Consciousness (SOC) task in which they discussed their breakup experience out loud for four minutes. These narratives were then transcribed and scored using the Interpersonal Decentering manual as adapted for Expressive Writing. Results indicate that – for women only – mature social cognition is inversely related to depressive mood at the initial visit. However, it is not related to initial PSTD symptomatology for men or women, nor does it predict decreases in depression and trauma symptomatology from the initial visit to the nine-week follow-up. Implications, limitations, and future directions for research of this nature are discussed.
