An agency-communion model of narcissism distinguishes between agentic narcissists (individuals satisfying self-motives of grandiosity, esteem, entitlement, and power in agentic domains) and communal narcissists (individuals satisfying the same self-motives in communal domains). Five studies supported the model. In Study 1, participants listed their grandiose self-thoughts. Two distinct types emerged: agentic ("I am the most intelligent person") and communal ("I am the most helpful person"). In Study 2, we relied on the listed communal grandiose self-thoughts to construct the Communal Narcissism Inventory. It was psychometrically sound, stable over time, and largely independent of the Narcissistic Personality Inventory-the standard measure of agentic narcissism. In Studies 3 and 4, agentic and communal narcissists shared the same self-motives, while crucially differing in their means for need satisfaction: Agentic narcissists capitalized on agentic means, communal narcissists on communal means. Study 5 revisited the puzzle of low self-other agreement regarding communal traits and behaviors. Attesting to the broader significance of our model, this low self-other agreement was partly due to communal narcissists: They saw themselves as high, but were seen by others as low, in communion.
