We examined the tendency to react to failure by derogating others. A situation was constructed to test this reaction among those posited to exhibit this behavior most often-narcissistically inclined individuals. The participants (N = 64) consisted of college students screened for pathological personality traits using self-report and peer report measures. Participants completed a two-part lab task and received false feedback indicating that they had been outperformed by fellow participants. Among self-report items, the best predictor of other-derogation was narcissism; among peer-report items, the best predictor items described cold, aloof, and avoidant personality tendencies. Findings are discussed with regard to identifying personality trait-situation-behavior patterns through multiple assessment methods. (C) 2002 Elsevier Science (USA). All rights reserved.
