Rapid video-referenced ratings of reciprocal social behavior in toddlers: a twin study.
J Child Psychol Psychiatry
December 2015
Article Synopsis
- Reciprocal social behavior (RSB) is crucial for social skills development and is often impaired in children with autism spectrum disorder (ASD), but there aren't effective ways to quantitatively measure RSB in toddlers yet.
- A new 20-minute video-referenced rating scale (vrRSB) was developed, allowing caregivers to reliably assess RSB in their toddlers, with high test-retest reliability observed over six months.
- Results showed a clear difference in RSB scores between children who passed and failed autism screening, strong heritability in scores among monozygotic twins, and a correlation with vocabulary development, indicating that RSB improves as toddlers grow.
