Executive function as measured by the Behavior Rating Inventory of Executive Function-2: children and adolescents with Williams syndrome.
C Greiner de Magalhães, C H Pitts, C B Mervis
PMID 34110652WHAT IT FOUND
Children with Williams syndrome show severe executive function deficits, particularly in cognitive regulation.
Inhibit difficulties predict attention problems, while Shift difficulties predict anxiety. These parent-reported deficits are unrelated to intellectual ability but strongly linked to poor adaptive living skills.
Key findings
01More than two-thirds of participants scored in the potentially clinically elevated or clinically elevated range on the Cognitive Regulation Index, indicating significant difficulty with executive function.
02Difficulty with inhibition was the only significant predictor of attention problems, while difficulty with shifting focus was a significant predictor of anxiety symptoms.
03Executive function deficits were not related to intellectual ability but were significantly related to behaviour problems and adaptive behaviour limitations.

What it does not show
The findings represent a group-level profile; the test cannot identify specific executive function profiles for individual children. Data relies entirely on parent report, which may vary based on parental expectations and does not include teacher reports. The study is cross-sectional, so it cannot determine if executive function deficits cause behavioral issues or if they co-occur due to other factors.
The easy way to misread this
Do not assume that executive function deficits in children with Williams syndrome are secondary to low intellectual ability. The study found no significant relationship between overall executive function scores and IQ, meaning these deficits require direct intervention regardless of the child's cognitive level.
