New Video Tool To Assist In The Autism Screening Process
An online video-guided screening tool may improve the reliability and accuracy of parent reports about autism-like behaviours.
A video-guided screening tool may boost the reliability of parent reports about autism-like behaviors, researchers reported yesterday at the 2016 International Meeting for Autism Research in Baltimore. The online tool could improve the accuracy of home-based autism screening and educate families about age-appropriate behaviors.
The Child Behavior Checklist and the Modified Checklist for Autism in Toddlers (M-CHAT) are fast and easy screening tools for autism. But the efficiency of these parent questionnaires comes at the cost of accuracy. These tests incorrectly flag as much as 88 percent of children who have conditions other than autism.
One source of inaccuracy comes from asking parents to judge their child’s behavior using vague or subjective measures. For example, a question asks whether the child ‘wants a lot of attention’ but does not explain what ‘a lot’ might mean for a child of that age. Some screening tests, including the M-CHAT, also require yes-or-no answers instead of graded responses.
