Video modeling and Test of Gross Motor Development-3 performance among children with autism spectrum disorder

Abstract

The purpose of this study was to explore the effects of video modeling on Test of Gross Motor Development-3 (TGMD-3) performance among children with autism spectrum disorder (ASD). Thirteen participants with ASD were assessed under two separate TGMD-3 protocol conditions-traditional and video modeling. Raters were blind to the protocol condition they were observing in order to prevent bias towards one condition. Total gross motor scores were analyzed using a one-way repeated-measures ANOVA. While improvements in overall gross motor scores with the video modeling condition were observed among children with ASD, differences were not statistically significant. Additionally, the video modeling condition took significantly longer time to complete than the traditional approach. The results do not provide support for the use of video modeling to improve TGMD-3 motor performance scores. Future research is necessary considering the promotion and use of video modeling is increasing.
