If your child has special needs they will need to take an IQ test every few years in order to maintain or modify services through your school district. For decades, the Wechsler Intelligence Scale for Children is the gold-standard test neuropsychologists use to determine the intellectual abilities of children with special needs. Unfortunately this test can take over two hours to administer and many children with special needs have a hard time participating in such a long test.

To solve this problem, researchers at the University of Missouri’s Thompson Center for Autism and Neurodevelopmental Disorders identified measures in the test that appeared to be repetitive and succeeded in shortening the test by up to 20 minutes while still maintaining its accuracy in determining a child’s IQ.

“As neuropsychologists, we spend a considerable amount of time — usually a full day or a full afternoon at least — with patients to really get to know them, and that can be a lot for a child with a neurological disorder like autism or attention deficit hyperactivity disorder (ADHD),” said John Lace, a doctoral student who is completing an internship in clinical neuropsychology in the MU School of Health Professions. “If we can efficiently maximize the information we get from our patients during this test without overburdening them, we can save time and money for both clinicians and patients, which reduces the overall health care burden on families with neurodevelopmental disabilities.”

Neuropsychologists use the Wechsler Intelligence Scale for Children test to not only assist in diagnosing individuals with neurodevelopmental disorders, but also to help inform decisions about treatment and educational plans.

“Our overall goal is to help people understand any cognitive or learning differences they may have, which can lead to treatment options such as behavioral therapy or interventions at school,” said Lace. “As neuropsychologists, our profession is at the crux of addressing these challenges both academically and practically to help clinicians streamline what they do and positively impact patient care.”
