Personality disorders may also share a correlation with a respective FFM domain but do so for different reasons. For instance, Saulsman and Page (2004, 2005) found that five of the personality disorders were meaningfully related to the domain of neuroticism. However, the current facet level analysis indicated that only one of these five personality disorders correlated above .20 with the facet of impulsivity (i.e., borderline). Similarly, in Saulsman and Page the paranoid, schizotypal, antisocial, borderline, and narcissistic personality disorders all correlated with low agreeableness, but the facet level analysis indicated that only narcissistic PD involves the facet of low modesty. The antisocial and dependent personality disorders both correlated with neuroticism but for entirely different reasons. Antisocial personality disorder correlated only with the facets of angry hostility and impulsiveness, whereas the dependent PD failed to correlate with these two facets, correlating instead with the other four facets of neuroticism. Thus, antisocial persons will obtain elevated scores on neuroticism due to their impulsiveness and angry hostility, whereas dependent persons may obtain a similar domain score but it will be because of an anxiousness, depressiveness, self-consciousness, and/or vulnerability that is not evident in antisocial persons.
