The Psychometric Properties of Turkish Version of Autism Spectrum Screening Questionnaire in Children aged 6-18 years

Objective: The objective of this study is to determine the psychometric properties of the Turkish version of the Autism Spectrum Screening Questionnaire (ASSQ-TR) and to find the best cutoff score for Pervasive Developmental Disorder (PDD) cases. Method: Children between 6 to 18 years old with diagnoses of PDD, Obsessive Compulsive Disorder (OCD), and Attention Deficit Hyperactivity Disorder (ADHD) were included. The healthy control (HC) group was recruited from children who did not have any psychiatric complaints or history. Furthermore, parents of 268 children filled the ASSQ-TR. Of the children, 51 were PDD, 67 were ADHD, 50 were OCD, and 100 were HC. In order to show the reliability of the ASSQ-TR, Cronbach's alpha values and test-retest were evaluated. ROC analyses was carried out to show concurrent validity and to determine the cutoff score. Results: The Cronbach's alpha of ASSQ-TR is 0,86, while the test retest reliability is r: 0,98. Total ASSQ-TR scores of children with PDD (27,96 +/- 9,5) were significantly higher than other groups (p
