Abstract

The diagnostic concepts of post-traumatic stress disorder (PTSD) and other disorders specifically associated with stress have been intensively discussed among neuro- and social scientists, clinicians, epidemiologists, public health planners and humanitarian aid workers around the world. PTSD and adjustment disorder are among the most widely used diagnoses in mental health care worldwide. This paper describes proposals that aim to maximize clinical utility for the classification and grouping of disorders specifically associated with stress in the forthcoming 11th revision of the International Classification of Diseases (ICD-11). Proposals include a narrower concept for PTSD that does not allow the diagnosis to be made based entirely on non-specific symptoms; a new complex PTSD category that comprises three clusters of intra- and interpersonal symptoms in addition to core PTSD symptoms; a new diagnosis of prolonged grief disorder, used to describe patients that undergo an intensely painful, disabling, and abnormally persistent response to bereavement; a major revision of "adjustment disorder" involving increased specification of symptoms; and a conceptualization of "acute stress reaction" as a normal phenomenon that still may require clinical intervention. These proposals were developed with specific considerations given to clinical utility and global applicability in both low- and high-income countries.

  • The ICD-11 proposal for complex PTSD was derived from the ICD-10 EPCACE diagnosis, but many aspects of its operationalization were based on the empirical literature that emerged from the DESNOS investigations.

    “The ICD-11 proposal for complex PTSD 23 was derived from the ICD-10 EPCACE diagnosis, but many aspects of its operationalization were based on the empirical literature that emerged from the DESNOS investigations.”

    From Emerging experience with selected new categories in the <scp>ICD</scp>‐11: complex <scp>PTSD</scp>, prolonged grief disorder, gaming disorder, and compulsive sexual behaviour disorder (2022) · cites this paper as [23]

    The Complex PTSD section says the proposal replaces the overlapping ICD-10 diagnosis of enduring personality change after catastrophic experience. It also says the proposed symptoms draw on recent research, including a cited DESNOS study, but names other research and expert opinion as well; it does not establish that many aspects of operationalization came from DESNOS investigations.

  • Symptoms of PGD are associated with impairment of the bereaved person's familial, social, and occupational functioning to a similar extent as depression and post-traumatic stress disorder.

    “Research have found symptoms of PGD to be associated with impairment of the bereaved person's famil ial, social, and occupational functioning to a similar extent as found for other mental disorders, e.g., depression and post-traumatic stress disorder (Jordan and Litz, 2014; Maercker et al., 2013; Prigerson et al., 2009; Shah and Meeks, 2012).”

    From Prevalence of prolonged grief disorder in adult bereavement: A systematic review and meta-analysis (2017) · cites this paper as Maercker et al., 2013

    The Prolonged grief disorder section says persistent severe grief is associated with significant impairment in general functioning and can make social activities difficult. It does not specify familial and occupational impairment or say that the impairment is similar in extent to that associated with depression or PTSD. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • The grouping of disorders specifically associated with stress brings together disorders in which the experience of an identifiable stressor is a requirement (though not sufficient) for manifestation of the condition.

    “The grouping of disorders specifically associated with stress brings together disorders in which the experience of an identifiable stressor is a requirement (though not sufficient) for manifestation of the condition.[48]”
  • Based on its review of the evidence, the ICD-11 Working Group on Disorders Specifically Associated with Stress recommended inclusion of complex PTSD in the ICD-11.

    “Based on its review of the evidence, the ICD-11 Working Group on Disorders Specifically Associated with Stress recommended inclusion of complex PTSD in the ICD-11 23 .”
  • PGD is included in the Appendix of DSM-5 and is expected to be included as a mental disorder in ICD-11.

    “From a nosological perspective, expansions and alignment of this research seems crucial as PGD is included in the Appendix of DSM-5 and is expected to be included as a mental disorder in ICD-11 (Bryant, 2014; Maciejewski et al., 2016; Maercker et al., 2013; Rosner, 2015).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
