University of Illinois researchers have found that measuring the quality of romantic relationships is more complex than previously conducted personality studies suggest.
Psychology professor Glenn Roisman and graduate student Ashley Holland say that while personality has been found to be predictive of perceived relationship satisfaction and success, other measures of relationship quality may offer additional insight into how a romantic relationship is functioning.
"Obviously there are going to be strong links between how you perceive your relationship and how you perceive yourself. But maybe there are not going to be such strong links between how you perceive yourself and how well you actually interact with your partner," said Holland, who led the research as part of her master's thesis.
"Our question was whether personality traits get reflected not just in how people perceive their relationships, but actually how they're behaving toward one another - and how their bodies respond while they interact," added Prof. Roisman, a co-author on the study.
For their study, the researchers gave dating, engaged and married participants a questionnaire about their own and their partners' personalities and the quality of their relationships.
The subjects were asked to indicate where they fell on a spectrum of each of the "big five" personality traits: extroversion, neuroticism, conscientiousness, agreeableness and openness to experience.
This part of the analysis confirmed that how an individual describes his own personality characteristics corresponds to how satisfied or dissatisfied he is in his romantic relationship.
