“…This component perpetrated at Level 6 of the hierarchy (although factor signs were reversed) and seemed to map the Detachment spectra (Kotov et al, 2017), being characterized by the higher factor loadings of PID‐5‐BF+ Detachment scale and CAPE Negative Symptom scale. Specifically, this component seemed to map a relevant aspect of psychosis (e.g., Muñoz‐Negro et al, 2017), such as HiTOP Detachment spectrum was conceived to include normal introversion, negative schizotypy traits, and negative symptoms of schizophrenia, ranging from sociable and expressive behavior to apathy, disinterest in people, and blunted affect (Kotov et al, 2022).…”

To examine the hierarchical structure of psychopathology and dysfunctional personality domains, 2416 Italian community‐dwelling adult volunteers were administered a set of psychometrically sound psychopathology measures and the Personality Inventory for DSM‐5 Brief Form+ (PID‐5‐BF+). Parallel analysis, minimum average partial, and very simple structure results suggested that 1–6 principal components (PCs) should be retained. Goldberg's bass‐ackwards model of the joint psychopathology measure and PID‐5‐BF+ ipsatized domain scale correlation matrix evidenced a hierarchical structure that was consistent with the working model proposed by the Hierarchical Taxonomy of Psychopathology (HiTOP) consortium. Hierarchical agglomerative cluster analysis around latent variables of the psychopathology indicators and PID‐5‐BF+ domain scales recovered four latent dimensions, which were akin to the corresponding bass‐ackwards components and nicely reproduced the HiTOP Internalizing, Externalizing, Thought Disorder, and Eating Pathology dimensions.

“…Similarly, the placements of symptoms that are used to diagnose obsessive–compulsive and related disorders and eating pathology have been a focus in several recent studies with implications for revisions and additions to the HiTOP framework (e.g., Cooper et al, 2023; Dunkley et al, 2020; Faure & Forbes, 2021; Marshall et al, 2020; Rossell et al, 2020). As research has begun to address disorder-level heterogeneity, it has become increasingly clear that symptom components from within one diagnosis can load on different HiTOP dimensions (e.g., negative schizophrenia symptoms loading on detachment, rather than thought disorder; Cicero et al, 2019; Kotov et al, 2022), so more fine-grained approaches to analysis may help to advance research in this area. A fundamental HiTOP aim is to move beyond traditional diagnostic categories to establish the empirical structure that emerges from quantitative analyses of comprehensive symptom-level and trait-level measurement of psychopathology.…”

Authors are listed in blocks that are intended to reflect their contributions to the manuscript and to developing the revisions process itself, although we note that these are crude distinctions, and the work has been a team effort spanning 5 years. Miriam K. Forbes and Aidan G. C. Wright led and oversaw the process of developing the revisions framework, as well as drafting and revising this manuscript. MKF also made the figures for the manuscript.

Quantitative, empirical approaches to establishing the structure of psychopathology hold promise to improve on traditional psychiatric classification systems. The Hierarchical Taxonomy of Psychopathology (HiTOP) is a framework that summarizes the substantial and growing body of quantitative evidence on the structure of psychopathology. To achieve its aims, HiTOP must incorporate emerging research in a systematic, ongoing fashion. In this paper, we introduce the conceptual background, organizing principles, core assumptions, and procedures for revising the HiTOP framework. Informed by strengths and shortcomings of previous classification systems, the proposed revisions protocol is a formalized system focused around three pillars: 1) prioritizing systematic evaluation of quantitative evidence by a set of transparent criteria and processes, 2) balancing stability with flexibility, and 3) promoting inclusion over gatekeeping in all aspects of the process. We detail how the revisions protocol will be applied in practice, including the scientific and administrative aspects of the process. Additionally, we describe areas of the HiTOP structure that will be a focus of early revisions and outline challenges for the revisions protocol moving forward. The proposed revisions protocol will ensure that the HiTOP framework reflects the current state of scientific knowledge on the structure of psychopathology and fulfills its potential to advance clinical research and practice.
