Narcissism in Romantic Relationships: Using Communal Activation to Promote Relationship Enhancing Attitudes.

People with elevated vulnerable narcissism (VN) or grandiose narcissism (GN) trait levels tend to experience greater difficulties in their romantic relationships than their counterparts with lower levels of VN or GN. Although there are no evidence-based approaches to alter the interpersonal behavior of persons with VN or GN traits, experimental research shows that it is possible to produce relationship-enhancing attitudes in people with GN traits through communal activation (CA). : We examined whether a CA manipulation in the context of relationship education improves attitudes that promote romantic relationship health, and whether VN and GN would moderate these associations. : Participants ( =148, = 71) watched psychoeducational videos on relationships and were randomly assigned to either answer questions about the videos' content (control group) or to complete CA exercises (experimental group) in addition to questionnaires to measure empathy, criticism, commitment, desire for closeness, and communication (positive interaction, demand/withdraw communication, criticize/defend communication) before and after the experimental manipulation. : There was a main effect of condition, such that, relative to the control group, fewer improvements in perceived demand/withdraw communication were observed in the experimental condition. VN, but not GN, moderated the link between condition and commitment, demand/withdraw and criticize/defend communication, such that elevated VN levels predicted the most improvement in commitment, demand/withdraw and criticize/defend communication in the experimental condition. : We conclude with recommendations to adopt ego-enhancing reinforcement for communal behaviors with clients who endorse GN traits and considering less personally relevant CA exercises with clients who endorse VN traits.
