State And Trait Narcissism Predict Everyday Helping

Though grandiose narcissism may seem incompatible with prosocial behavior, evidence of how they relate is mixed. We extend research on this relation by (1) assessing everyday helping, (2) distinguishing narcissistic admiration and rivalry, and (3) assessing state narcissism. Using daily diary methodology and multilevel modeling (N = 380; total observations = 4292), we assess trait narcissism (grandiose, admiration and rivalry), state narcissism, and daily helping over 14 days. Trait grandiose narcissism positively predicted helping but narcissistic rivalry predicted it negatively. State narcissism also positively predicted helping: Participants reported more helping on days they felt more narcissistic. Mood, however, interacted with state narcissism: state narcissism predicted greater helping when daily mood was low but not high.
