Screening for autism in early intervention. From 16–30 months, we have the M-CHAT-R. What do you use beyond 30 months? The SRS-2 is an option now, but there is not a lot of research on how well it works yet. The SCQ starts at 4 years. And all of those are completed through parent report.
What if we had a screener that combined parent report with objective measurement, that could be administered on a parent’s smart phone? Enter Cognoa!
This two-part screener, intended for ages 18–72 months, is contained in a mobile app. Parents answer 15 questions (similar to the M-CHAT-R or SCQ), and then are prompted to record 1- to 2-minute videos of their children in everyday interactions. The questionnaire is scored immediately, and the videos are reviewed by experienced clinicians for a rating score. All of those scores go into algorithms (yay technology) to determine level of risk. Results are then sent to the family, physician, EI team, etc. Kanne, et al. evaluated Cognoa against other screening measures like the M-CHAT-R, SCQ, SRS, and CBCL and found it to be comparatively sensitive and more specific than those screenings. In other words, Cognoa correctly flagged for ASD evaluation as well as the screenings we already use, and it had fewer false positive screenings. Not bad! Unfortunately, there is a downside. Currently, Cognoa is only really available for parents whose employers buy access to the screenings as a health incentive to their employees. In the meantime, we might have to stick with the measures we already know, but keep your eyes and ears peeled in case this app picks up steam!

Hey, wait! This isn’t the only article on autism screening tools found this month! Janvier et al. found that a simple picture-based developmental checklist could successfully differentiate children with and without ASD among low-income, minority families. This screening tool, The Developmental Check In, may be a useful way to screen for autism among underserved children, particularly when parents are not native English speakers.
