Personality in a Hierarchical Model of Psychopathology
The categorical model of classification in the American Psychiatric Association’s (APA) Diagnostic and Statistical Manual of Mental Disorders (DSM-5; APA, 2013) is sorely problematic. A proposed solution is emerging in the form of a quantitative nosology, an empirically based dimensional organization of psychopathology. More specifically, a team of investigators has proposed a Hierarchical Taxonomy Of Psychopathology (HiTOP; Kotov et al., 2017). The purpose of the current paper is to discuss the potential role, importance, and implications of personality within the HiTOP dimensional model of psychopathology. Suggested herein is that personality provides a foundational base for the HiTOP dimensional model of psychopathology. Implications concern the potential value of early assessment of and screening for personality as well as the development of protocols for the treatment of personality trait domains, which may in turn contribute to substantial improvements in quality of life, as well as mental and physical health.
