|Abstract:||AIM: We examined the validity of the PTSD Symptom Scale - Self-Report (PSS-SR) as a screening instrument for post-traumatic stress disorder (PTSD) in patients recovering from first-episode psychosis. METHODS: Sixty-one patients from the Early Psychosis Intervention Programme in Singapore completed the PSS-SR questionnaire. The Clinician-Administered PTSD Scale was administered by a blinded interviewer as the 'gold standard' to identify patients with PTSD. The sensitivity, specificity and receiver operating characteristic curve were used to determine the screening performance of the PSS-SR. RESULTS: The score representing the optimal cut-off point for the PSS-SR was 14, with a sensitivity and specificity of 0.83 and 0.71, respectively. The area under the curve was determined to be 0.82 (95% CI: 0.70-0.95). CONCLUSION: These data suggest that the PSS-SR can be a useful screening instrument for PTSD in patients recovering from their first psychotic episode.|
