When the Partner's Reality Bites: Associations Between Self- and Partner Ratings of Psychopathic Traits, Relationship Quality and Conflict Tactics.

The present study examined associations of self- and partner-reported psychopathic traits, as well as the level of agreement between these reports (perceptual accuracy), with relationship quality, and the moderating role of violent and non-violent conflict tactics. Participants were 259 heterosexual couples from the community. Results indicated that, despite moderate convergence between self- and partner-reports, the female partners tended to underreport the levels of psychopathic traits in their male partner. Relationship quality was negatively associated with partner-reported and, albeit to a lesser extent, self-reported psychopathic traits. Contrary to expectations, perceptual accuracy was barely associated with relationship quality. Whereas no evidence was found for the moderating role of aggressive conflict tactics, non-violent negotiation seemed to buffer the effect of psychopathic traits on relationship quality. The study highlights the importance of considering the partner's perceptions as well as constructive conflict tactics when examining psychopathic traits in intimate relationships.
