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.
To determine the validity of the Trauma Screening Questionnaire (TSQ) as a screening tool for PTSD among individuals with psychotic disorders.
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).
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.
The TSQ seems to be a valid screening tool for PTSD in patients with a psychotic disorder.
The T.TIP trial, including the TSQ study, is supported by the Dutch Support Foundation ‘Stichting tot Steun VCVGZ’ (awarded to the principal investigator M.v.d.G.). The Dutch Support Foundation ‘Stichting tot Steun VCVGZ’ played no further role in any of the aspects or phases of this study.
