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.
