Summary
This study presents a reliable assessment for joint attention in children with autism spectrum disorder (ASD) and typically developing peers. Children with ASD showed more significant difficulties initiating joint attention than responding to it.
Area of Science:
- Developmental Psychology
- Clinical Psychology
- Neurodevelopmental Disorders
Background:
- Joint attention is crucial for social and cognitive development.
- Deficits in joint attention are a hallmark of autism spectrum disorder (ASD).
- Objective and reliable assessment tools are needed to quantify these deficits.
Purpose of the Study:
- To describe a structured assessment protocol for joint attention behaviors.
- To evaluate the reliability and validity of this protocol in children with and without ASD.
- To compare joint attention responding and initiation in young children with ASD and typically developing (TD) children.
Main Methods:
- A structured assessment protocol with objective behavioral measures was developed.
- The protocol was administered to 26 children with ASD and 21 TD children, aged 2-4 years.
- Interobserver agreement was calculated to ensure reliability.
Main Results:
- High interobserver agreement was achieved for all behavioral measures.
- Children with ASD exhibited minor deficits in joint attention responding.
- Children with ASD showed more severe deficits in joint attention initiation compared to TD children.
Conclusions:
- The developed protocol reliably assesses joint attention behaviors.
- The findings confirm and quantify specific joint attention challenges in young children with ASD.
- This reliable assessment can aid in early identification and intervention planning for ASD.
