Identifying Psychopathy Subtypes Using a Broader Model of Personality: An Investigation of the Five Factor Model Using Model-Based Cluster Analysis.

Early research examined psychopathy subtypes in terms of traits specific to psychopathy. However, recent research suggests that psychopathy may be conceptualized more dimensionally as an extreme variation in normative personality traits.
