Reliability And Validity Of The Schedule For Affective Disorders And Schizophrenia For School-Age Children-Present And Lifetime Version, Dsm-5 November 2016-Turkish Adaptation (K-Sads-Pl-Dsm-5-T)

Abstract

Objective: The aim of this study was evaluate the reliability and validity of the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version, DSM-5 November 2016 -Turkish Adaptation (K-SADS-PL-DSM-5-T). Method: A total of 150 children and adolescents between 6 and 17 years of age were assessed with K-SADS-PL-DSM-5-T. The degree of agreement between the DSM-5 criteria diagnoses and the K-SADS-PL-DSM-5-T diagnoses were considered as the measure of consensus validity. In addition, concurrent validity was examined by analyzing the correlation between the diagnoses on K-SADS-PL-DSM-5-T and relevant scales. Interrater reliabilities were assessed on randomly selected 20 participants. Likewise, randomly selected 20 other participants were interviewed with K-SADS-PL-DSM-5-T three weeks after the first interview to evaluate test-retest reliability. Results: The consistency of diagnoses was almost perfect for eating disorders, selective mutism and autism spectrum disorder (K=0.92-1.0), substantial for elimination disorders, obsessive-compulsive disorder, oppositional defiant disorder, generalized anxiety disorder, social anxiety disorder, depressive disorders, disruptive mood dysregulation disorder and attention deficit hyperactivity disorder (K=0.67-0.80). Interrater reliability was perfect for selective mucism (K=1.0), substantial for oppositional defiant disorder, disruptive mood dysregulation disorder, attention deficit hyperactivity disorder, depressive disorders and social anxiety disorder (K=0.63-0.73). Test-retest reliability was almost perfect for autism spectrum disorder (K=0.82), substantial for attention deficit hyperactivity disorder, oppositional defiant disorder, disruptive mood dysregulation disorder, depressive disorders and generalized anxiety disorder (K=0.62-0.78). Conclusion: The results of this study show that the K-SADS-PL-DSM-5-T is an effective instrument for diagnosing major childhood psychiatric disorders including selective mutism, disruptive mood dysregulation disorder and autism spectrum disorder which have recently been added to the schedule.
