Background: The validity and reliability of a Persian version of the Kiddie Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version (K-SADS-PL-P) was evaluated.
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.
