    Development and Validation of the Single Item Narcissism Scale (SINS)
    (PLOS, 2014-08-05) Konrath, Sara H.; Meier, Brian P.; Bushman, Brad J.
    Main Objectives The narcissistic personality is characterized by grandiosity, entitlement, and low empathy. This paper describes the development and validation of the Single Item Narcissism Scale (SINS). Although the use of longer instruments is superior in most circumstances, we recommend the SINS in some circumstances (e.g. under serious time constraints, online studies). Methods In 11 independent studies (total N = 2,250), we demonstrate the SINS' psychometric properties. Results The SINS is significantly correlated with longer narcissism scales, but uncorrelated with self-esteem. It also has high test-retest reliability. We validate the SINS in a variety of samples (e.g., undergraduates, nationally representative adults), intrapersonal correlates (e.g., positive affect, depression), and interpersonal correlates (e.g., aggression, relationship quality, prosocial behavior). The SINS taps into the more fragile and less desirable components of narcissism. Significance The SINS can be a useful tool for researchers, especially when it is important to measure narcissism with constraints preventing the use of longer measures.

    Narcissism
    (2014) Konrath, Sara H.; Bonadonna, John P.
    Narcissism is a personality trait that is characterized by excessively positive self-views and low empathy. It is a complex constellation consisting of mostly positive individual correlates and mostly negative social correlates. We present two different theoretical models that attempt to reconcile these apparently contradictory implications of narcissism. There are predictable age and gender differences in narcissism. In addition, narcissism is relatively high in Western individualistic cultures, and increasing over time in the United States, yet it is relatively lower in Eastern collectivistic cultures. This suggests that cultural norms and developmental experiences can possibly influence it.

    Physiological and health-related correlates of the narcissistic personality
    (2014) Konrath, Sara H.; Bonadonna, John P.
    Narcissism is a personality trait that is characterized by excessively high self-esteem in combination with low empathy. Since the development of sound instruments to measure the narcissistic personality in the 1970s, scholars have discovered a lot about the interpersonal correlates and consequences of narcissism. For example, people scoring high on narcissism have difficulty maintaining healthy, long-term close relationships and have a tendency to behave aggressively in response to critical feedback. In the current chapter, we summarize known health (Part I) and physiological correlates (Part II) of the narcissistic personality. We review the well-developed literature on narcissism and psychological health, and then move on to less developed research on cognitive performance, health-risk behaviors, and physical-health outcomes, including mortality risk. Research that goes beyond self-reports and examines the physiological underpinnings of the narcissistic personality is very rare, but it is important to use such measures, given narcissistic tendencies to self-enhance. Thus, we thoroughly review the extant literature examining cardiovascular, endocrine, neural, and genetic correlates of narcissism. Given the limited amount of research on this topic, we conclude by discussing potential directions for future research.
