Research concerning the role of narcissism in influencing perceptions of situations is sparse. In this study, the daily in#uences of two compone,18 of trait narcissism, admiration and rivalry, were explored using narrative life-logging cameras. We examined the in#uences of admiration and rivalry on perceptions of situation desire, situation choice, momentary self-esteem, authenticity, and the DIAMONDS (Duty, Intellect, Adversity, Mating, pOsitivity, Negativity, Deception, and Sociality) characteristics of situations among a sample of undergraduate students. Rivalry was found to be predictive of lower situation desire and choice, while admiration and overall narcissism were not. Admiration showed a significant positive association with both momentary self-esteem and momentary authenticity, while rivalry showed a negative association with these two variables. Patterns emerged demonstrating that the two facets, admiralion and rivalry, diferentially predict perceptions of the DIAMONDS characteristics of situations. This research hirther illuminates the need to study narcissism as muitidimensional and provides various implications for counselors working with clients· who display narcissistic tendencies.
