Quantitative assessment of autistic symptomatology in preschoolers.

Pine et al. (2006) tested the 15-minute Social Responsiveness Scale on preschoolers. They wanted to know if the short parent form gives stable, trustworthy scores for kids under six.

The team gave the SRS twice to a group of children with autism and to typically developing peers. They checked if scores stayed the same and if they lined up with other autism measures.

The SRS showed good reliability and its scores moved in step with other autism tools. Autistic-trait scores dropped slightly over time, even before treatment started.

This means the scale can track small changes, making it useful for watching progress during early intervention.

Constantino et al. (2003) first showed the SRS matches the long ADI-R in older kids. Pine et al. (2006) extends that work down to preschool, proving the same 15-minute form still works at age three.

Scahill et al. (2015) later pooled many studies and listed the SRS as one of only five tools ready for clinical trials. Their review treats the 2006 preschool data as key evidence.

Lubomirska et al. (2022) built a new preschool screener called SoROS. Both papers agree brief parent reports can flag autism early, but the SRS is already trial-ready while SoROS is still new.

You can give the SRS in the waiting room before therapy starts. It takes parents 15 minutes and gives you a number you can trust. Re-score every three months to see if your treatment is moving the needle. No extra clinic time, no long interview, just a quick snapshot that holds up in research and in court reports.
