Abstract
Research has examined the use of basic personality traits in describing problematic personality traits, such as borderline and psychopathic traits. Specifically, the Honesty–Humility factor of the HEXACO model of personality appears to account for a large proportion of the variance in these traits. The purpose of the present study was to examine whether the HEXACO model would similarly predict borderline traits. As found in previous research, psychopathic traits were predicted by low Honesty–Humility, Emotionality, Agreeableness, and Conscientiousness, whereas borderline traits were found to be negatively related to eXtraversion and Conscientiousness but had a significantly positive relationship with Emotionality. As Emotionality appeared to be a differential predictor in this study, future research should further examine how Emotionality distinguishes between the various problematic personality traits, which may aid potential treatments/therapies.
