Our current nosology of psychopathology relies on a categorical model that has notable limitations. For example, this medical model of classifying mental disorders does not account for the significant heterogeneity of symptom presentations across psychopathology. Today, we speak with Robert Latzman, Ph.D., to discuss the Hierarchical Taxonomy of Psychopathology (HiTOP), an alternative nosology that uses factor analysis to address the issues with our current diagnostic classification standard.

- Overview of the Hierarchical Taxonomy of Psychopathology (HiTOP)
- Major challenges to our current nosology of psychopathology
- Comparing the diagnostic approach between the DSM-5 and HiTOP
- The role of exploratory and confirmatory factor analysis in HiTOP
- The “p” factor of psychopathology
- Integrating HiTOP with the RDoC to improve clinical research
- Assessment instruments that are consistent with HiTOP
- Limitations in structured diagnostic inventories
- How HiTOP can inform the next iteration of the DSM
- The clinical utility of HiTOP in psychiatric and neurocognitive disorders
Dr. Robert D. Latzman received his Ph.D. in Clinical Psychology from the University of Iowa. He completed his internship and his postdoctoral fellowship at the University of Mississippi Medical Center. Rob is currently an Associate Professor in the Department of Psychology at Georgia State University. He is interested in characterizing etiological mechanisms that underlie the development of externalizing disorders and related psychopathology, including aggression, delinquency, substance use, and psychopathy. He is also interested in the development of a multi-modal and dimensional model that examines the role of individual differences as central mechanisms in the clinical manifestation of psychopathology (i.e., the Hierarchical Taxonomy of Psychopathology; HiTOP). Rob is the co-chair of the HiTOP neurobiological foundations workgroup.
