The Dark Triad (narcissism, Machiavellianism, psychopathy) represent subclinical but prototypically antisocial personality traits. Obsessive relational intrusion (ORI) represents a continuum of behaviors common to the crime of stalking. Substantive proportions of stalkers have clinical disorders, but the majority are subclinical and do not have diagnosed disorders. The purpose of this study was to investigate personality traits associated with the Dark Triad as possible predictors of perpetrating obsessive relational intrusion. Because there are examples of socially successful Dark Triadic individuals, this study also investigated the roles of adult attachment style and communication competence as moderators in ORI perpetration. The data show that Dark Triad traits and ORI perpetration are positively correlated, however, only psychopathy emerged as a strong, individual predictor of ORI perpetration.
