The Five-Factor Model of Personality (FFM) has been used to conceptualize personality disorders as maladaptive variants of normal personality traits. This study assessed the convergence of 6 lower order traits, or facets, of FFM agreeableness versus antagonism (trust, straightforwardness, altruism, compliance, modesty, and tender-mindedness) with antisocial, borderline, narcissistic, paranoid, and passive-aggressive personality traits. Interview-based scores for all of the antagonism facets except compliance demonstrated the expected relations with these personality disorder traits. Results for self-reported facet scores were less clearly supportive, only yielding convergence for straightforwardness and altruism with respect to antisocial traits. It is suggested that future investigations of the FFM, or other normal personality trait models, and personality disorder symptomatology include analyses at the lower order trait level.
