Assessment & Research

Agreement of parent-reported cognitive level with standardized measures among children with autism spectrum disorder.

Lee et al. (2023) · Autism research : official journal of the International Society for Autism Research 2023
★ The Verdict

A short parent survey gives a good-enough IQ range for research and helps you spot kids whose daily skills lag behind their scores.

✓ Read this if BCBAs doing intake or program planning for autistic clients of any age.
✗ Skip if Clinicians who already have recent full-scale IQ scores for every client.

01Research in Context

01

What this study did

The team asked parents a few short questions about past IQ tests and diagnoses.

They compared the answers to real test scores already on file.

Kids had autism and ranged from toddlers to teens.

02

What they found

Parent guesses matched the real scores well enough for big research use.

Agreement was best when kids were older, had clearer IQ ranges, fewer autistic traits, and stronger daily-living skills.

03

How this fits with other research

Wang et al. (2024) and Chang et al. (2013) show the same kids often score high on IQ yet still struggle with daily tasks.

Richman et al. (2001) found this gap years earlier, so the new survey tool now lets us spot the mismatch faster in large samples.

Ben-Itzchak et al. (2014) warn that only kids with baseline DQ above 70 keep their gains in real-life skills; quick parent questions can flag who needs extra adaptive teaching early.

04

Why it matters

You can open intake with four parent questions instead of waiting months for full testing.

If parents say high IQ but you see low adaptive scores, start teaching dressing, chores, and social routines right away.

This saves clinic time and gets kids the life-skills help they actually need.

03Original abstract

Assessing cognitive development is critical in clinical research of autism spectrum disorder (ASD). However, collecting cognitive data from clinically administered assessments can add a significant burden to clinical research in ASD due to the substantial cost and time required, and it is often prohibitive in large-scale studies. There is a need for more efficient, but reliable, methods to estimate cognitive functioning for researchers, clinicians, and families. To examine the degree to which caregiver estimates of cognitive level agree with actual measured intelligence/developmental scores and understand factors that may impact that agreement, 1,555 autistic individuals (81.74% male; age 18 months-18 years) were selected from a large cohort (Simons Foundation Powering Autism Research for Knowledge, SPARK). Results suggest that querying parents about recent testing results and developmental diagnoses can provide valid and useful information on cognitive ability. The agreement of parental estimates varied with age, measured cognitive ability, autistic traits, and adaptive skills. In the context of large-scale research efforts, parent-reported cognitive impairment may be a good proxy for categorical IQ range for survey-based studies when specific IQ scores are not available, circumventing the logistical and financial obstacles of obtaining neuropsychological or neurodevelopmental testing.
