title: Temperament as a unifying basis for personality and psychopathology.
abstract: Personality and psychopathology long have been viewed as related domains, but the precise nature of their relations remains unclear. Through most of the 20th century, they were studied as separate fields; within psychopathology, clinical syndromes were separated from personality disorders in 1980. This division led to the revelation of substantial overlap among disorders both within and across axes and to the joint study of normal and abnormal personality. The author reviews these literatures and proposes an integrative framework to explain personality-psychopathology relations: Three broad, innate temperament dimensions--negative affectivity, positive affectivity, and disinhibition--differentiate through both biologically and environmentally based developmental processes into a hierarchical personality trait structure and, at their extremes, are risk factors (diatheses) for psychopathology, especially given adverse life experiences (stress).
