Abstract

Questions form essential components of everyday speech; therefore, it is appropriate to evaluate children with autism to understand what they are asking during the daily conversation. A proper tool is required to assess questions formed through interrogative pronouns (what are commonly known as Wh-questions). The present study investigates the validity and reliability of the WH-Question comprehension test in children with autism. A sample of 52 neurotypical children were recruited from nursery and primary schools, and a sample of 28 children with autism were recruited from different centers for children with autism. The WH-Comprehension test was translated into Persian according to the international test commission (ITC) guideline. The reliability of the test was determined by test-retest and Cronbach’s alpha approach. The face validity of the Persian version of the “WH-Comprehension test” was confirmed. The CVR for the test was equal to 0.85%, and the CVI was equal to 0.89%. Furthermore, the Intraclass Correlation Coefficient (ICC) for the total score was equal to 0.95, and Cronbach’s Alpha Coefficient was calculated as 0.92. The results indicate that the translated WH-Comprehension test has acceptable validity and reliability within the sampled Persian groups and can be a helpful research tool. © 2022 Taylor & Francis Group, LLC.
