Abstract

Background Although only a few people exposed to a traumatic event (TE) develop posttraumatic stress disorder (PTSD), symptoms that do not meet full PTSD criteria are common and often clinically significant. Individuals with these symptoms sometimes have been characterized as having subthreshold PTSD, but no consensus exists on the optimal definition of this term. Data from a large cross-national epidemiologic survey are used in this study to provide a principled basis for such a definition.Methods The World Health Organization World Mental Health Surveys administered fully structured psychiatric diagnostic interviews to community samples in 13 countries containing assessments of PTSD associated with randomly selected TEs. Focusing on the 23,936 respondents reporting lifetime TE exposure, associations of approximated DSM-5 PTSD symptom profiles with six outcomes (distress-impairment, suicidality, comorbid fear-distress disorders, PTSD symptom duration) were examined to investigate implications of different subthreshold definitions.Results Although consistently highest outcomes for distress-impairment, suicidality, comorbidity, and PTSD symptom duration were observed among the 3.0% of respondents with DSM-5 PTSD rather than other symptom profiles, the additional 3.6% of respondents meeting two or three of DSM-5 criteria B-E also had significantly elevated scores for most outcomes. The proportion of cases with threshold versus subthreshold PTSD varied depending on TE type, with threshold PTSD more common following interpersonal violence and subthreshold PTSD more common following events happening to loved ones.Conclusions Subthreshold DSM-5 PTSD is most usefully defined as meeting two or three of DSM-5 criteria B-E. Use of a consistent definition is critical to advance understanding of the prevalence, predictors, and clinical significance of subthreshold PTSD.

  • During the COVID-19 pandemic, the prevalence of self-reported modest-to-severe posttraumatic stress symptoms in the global general population ranged from 7% to 53.8%, compared with a world average of 3.9%-7.8% prior to the pandemic.

    “The prevalence of self-reported modest-to-severe posttraumatic stress symptoms in the global general population ranged from 7 % to 53.8 % during the pandemic (Xiong et al., 2020; Krishnamoorthy et al., 2020), compared to the world average of 3.9 %–7.8 % prior to the pandemic (McLaughlin et al., 2015; Koenen et al., 2017).”

    The Results section (Prevalence of PTSD symptom profiles; page unavailable) provides a pre-pandemic, cross-national PTSD estimate, but reports 3.0% meeting the study’s approximation of DSM-5 PTSD and an additional 4.6% meeting at least one subthreshold definition—not the claimed 3.9%–7.8%. The Methods (Samples; page unavailable) cover trauma-exposed respondents in 13 countries, so these estimates are not presented as a world average for the general population. The pandemic range is attributed to other citations, not this paper. (LLM, conf=0.84)

  • In a WHO World Mental Health Survey of 23,936 trauma-exposed people across 13 countries, 6.6% evidenced clinical or subclinical PTSD symptoms consistent with DSM-V criteria.

  • Subthreshold PTSD is more prevalent in the community than full PTSD.

    “While this condition does not fulfill the diagnosis of PTSD, it is found to be more prevalent in the community [4].”

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.
