Abstract

Background: Post-traumatic stress disorder (PTSD) is highly prevalent in patients with a psychotic disorder. Because a PTSD diagnosis is often missed in patients with psychosis in routine care, a valid screening instrument could be helpful. Aims: To determine the validity of the Trauma Screening Questionnaire (TSQ) as a screening tool for PTSD among individuals with psychotic disorders. Method: Among 2608 patients with a psychotic disorder, the rate of trauma exposure was determined and the TSQ was administered to screen for PTSD. PTSD status was verified in 455 patients using the Clinician-Administered PTSD Scale (trial registration: ISRCTN 79584912). Results: Trauma exposure was reported by 78.2% of the 2608 patients. PTSD prevalence was estimated at 16% (95% CI 14.6–17.4%) compared with 0.5% reported in the patients' clinical charts. A TSQ cut-off score of six predicted PTSD with 78.8% sensitivity, 75.6% specificity, 44.5% correct positives and 93.6% correct negatives. Conclusions: The TSQ seems to be a valid screening tool for PTSD in patients with a psychotic disorder.

  • The estimated under-report of PTSD in clinical practice is as much as 96.9%.

    “Research of de Bont et al. (19) indicates an estimated under-report of PTSD of as much as 96,9% in clinical practice.”

    From Making meaning of trauma in psychosis (2023) · cites this paper as de Bont et al. (19)

    The section ‘Clinical documentation of PTSD in patients with psychotic disorders’ reports an estimated 96.9% under-report in clinical practice, comparing estimated PTSD prevalence with diagnoses recorded by mental health organisations. That estimate is for the study’s sample of patients with psychotic disorders; the citing sentence omits this population limit. (LLM, conf=0.87)

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.
