Hierarchical Taxonomy of Psychopathology (HiTOP)

The Hierarchical Taxonomy of Psychopathology (HiTOP) consortium is an effort by nosologists from mental health disciplines to describe and measure psychopathology. HiTOP seeks to facilitate research and clinical practice by developing more informative nosology than current psychiatric classification systems (DSM-5, ICD-11) by addressing limitations such as arbitrary boundaries between psychopathology and normality, frequent co-occurrence of disorders, heterogeneity within disorders, and diagnostic instability. The consortium was founded in 2015 and has since grown rapidly to over 160 members with over 30 published papers that have advanced the classification of psychopathology.

The consortium includes a Developmental workgroup, which Dr. Wilson co-chairs. The Developmental workgroup seeks to incorporate developmental considerations into the creation of HiTOP measures, elaborate on how the HiTOP model represents psychopathology across the lifespan, and develop conceptual and empirical bridges among clinical constructs in order to promote a taxonomy that aligns with the temperament, personality, and psychopathology literatures.
