Method: The K‐SADS‐PL‐P was administered to 102 inpatients (mean age = 15.3 yrs, SD = 1.81) in a child and adolescent psychiatric ward. The psychometric properties were evaluated in comparison to the results of clinical diagnosis. Results: The K‐SADS‐PL‐P showed good‐to‐excellent concurrent validity in diagnosing current major disorders. Test‐retest reliabilities of most of the current diagnoses were also good to excellent. Conclusion: The Persian version of the K‐SADS‐PL provides reliable and valid youth psychiatric diagnoses.
