Abstract
The Test of Gross Motor Development – 3rd Edition (Ulrich, 2016) has been suggested in the autism spectrum with visual support, in this study, standardization in healthy boys and autism has been investigated. The strategy, design, and method of the research were descriptive-normative, cross-sectional and clinical. The samples of research were 160 children with an average age of 7.73 ± 3.09 from 3-10-year-old boys in Urmia that 80 boys with autism spectrum disorder and 80 boys were normal and had no disorder or developmental- delay. The data collection tool was TGMD-3 test with the visual support that evaluated children's fundamental skills in the age range of 3 to 10 years. This test consists of six locomotion and seven ball skills. The reliability of the test by Cronbach's alpha, the interrater reliability, the intrarater reliability, and the retest showed that the TGMD-3 test in healthy boys and TGMD-3 with vision support in children with autism is a lasting tool. The validity of the test was also evaluated by comparing the raw scores of healthy and autism children, confirmatory factor analysis and age correlation with the gross motor function of children. Healthy children had a significant superiority in motor function compared to children with autism, and the motor function of autism children with visual support was significantly improved compared with the test without visual support. Finally, the association between age and locomotion subtest, ball skill and the total raw score of both the autism and healthy children was confirmed and in locomotion subtest in the test with visual support was obtained at a very low level. The Test of Gross Motor Development – 3rd Edition as a valid and reliable test in healthy and autistic children in 3-10age range has the credibility and reliability of evaluation and use.
