Adaptive behavior in Chinese children with Williams syndrome

Area of Science:

• Neurodevelopmental disorders
• Pediatric psychology
• Behavioral genetics

Background:

• Williams syndrome (WS) is a genetic disorder with distinct psychological and behavioral characteristics.
• WS affects multiple cognitive domains, notably social behavior patterns.
• Understanding adaptive behavior in WS is crucial for targeted interventions.

Purpose of the Study:

• To investigate adaptive behavior in Chinese children with Williams syndrome.
• To compare the adaptive functioning of WS children with typically developing controls.

Main Methods:

• A structured interview using the Infants-Junior Middle School Students Social-life Abilities Scale was administered.
• Participants included children with WS (n=26), typically developing children matched for mental age (MA, n=30), and typically developing children matched for chronological age (CA, n=40).
• Mean scores for adaptive behavior domains were compared across the three groups.

Main Results:

• WS children had more siblings and lower caregiver education levels than controls.
• No significant differences were found in locomotion, work skill, socialization, or self-management between WS and MA groups.
• WS children showed significantly higher self-dependence and communication skills compared to the MA group, but lower overall adaptive behavior scores than the CA group.

Conclusions:

• Williams syndrome children exhibit enhanced self-dependence and communication abilities relative to mental-age-matched peers.
• Intervention strategies should focus on promoting social development in individuals with WS.
• Findings highlight the complex adaptive profile in Williams syndrome.
