Abstract:
The personality structure of persons within clinical populations may not be fundamentally different from the personality structure of persons who have not sought treatment for their maladaptive personality traits. Indeed, there has long been an interest in understanding personality disorders as maladaptive variants of general personality structure. Presented herein is an understanding of personality disorder from the perspective of basic personality research; more specifically, the five factor model (FFM) of general personality structure. Potential advantages of understanding personality disorders from the perspective of the FFM are provided.
