Brief Report: Is IQ Measured Equally in ASD, ADHD, Language Disorders, and the General Population?
Article in Journal of autism and developmental disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeAutism spectrum disorder (ASD) is a heterogeneous condition that has led some to question whether IQ scores can be meaningfully compared across neurodivergent and neurotypical populations. The purpose of this study was to evaluate the measurement invariance of the Stanford-Binet Intelligence Scales, Fifth Edition (SB-5), among 3,050 clinically referred youth ages 2-16 with a diagnosis of ASD (n = 1,329; 43.6%), ADHD (n = 942; 30.9%), or a language-related disorder (n = 779; 25.5%), as well as the general population standardization sample within the same age range.
methodsThe clinical sample consisted of retrospective chart review data from a large pediatric hospital in the Midwestern United States. We used multigroup confirmatory factor analysis to test measurement invariance.
resultsThe three clinical groups demonstrated full strong (scalar) invariance. The combined clinical sample also demonstrated full strong (scalar) invariance relative to the standardization sample.
conclusionThese findings indicate that the SB-5 measures IQ in a consistent manner across both general and clinical populations, including the three most common neurodevelopmental disorders, supporting the meaningful comparison of scores across these groups.
