PMID 40366092WHAT IT FOUND
People with intellectual disability and autism showed lower emotional development scores than those with intellectual disability only.
This pattern held across all eight domains of the assessment tool, suggesting autism adds specific challenges to emotional growth.
Key findings
01The group with both intellectual disability and autism had significantly lower total emotional development scores than the group with intellectual disability only.
02Individuals with both intellectual disability and autism showed lower emotional development levels in all eight assessed domains compared to those with intellectual disability only.
03Item-level analysis revealed significant differences in responses for 27 out of 200 items, with the autism group showing fewer affirmative responses on average.

What it does not show
The study relied on informant reports, which may be biased or inaccurate, especially for complex emotional behaviors. There was a high rate of psychiatric comorbidity in the sample, which could influence the results. Diagnoses were based on ICD-10 criteria without a standardized diagnostic procedure across the three countries involved. The number of participants at the higher emotional development stages (4 and 5) was very small, limiting the reliability of findings for those groups. The study design is cross-sectional, so it cannot determine causality or track development over time.
Declared interests
One author received royalties from publishers for the SED-S manual. The study was funded by ZonMW and the Bartiméus Fund.
The easy way to misread this
Do not assume that emotional development differences are solely due to autism severity or intellectual disability level, as the study matched for these factors. Also, be cautious in generalizing findings to higher developmental stages, as very few participants reached stages 4 and 5.
