New longitudinal research investigated how narcissism affects romantic relationships. The study followed more than 5,000 couples for up to six years and was published in the Journal of Personality. Participants completed questionnaires that measured two dimensions of narcissism: narcissistic admiration and narcissistic rivalry.
Researchers explained that admiration involves puffing oneself up to impress others, while rivalry involves putting others down to appear superior. The results showed that rivalry traits were consistently associated with lower relationship satisfaction for both partners. By contrast, admiration had no meaningful effect on partner satisfaction.
The study also found that the rate of decline in satisfaction was not steeper for couples where one partner scored highly on narcissism, and relationships under one year showed no link between narcissistic traits and satisfaction. Lead author Gwendolyn Seidman of Michigan State University said the reality may be more complicated than common assumptions.
