Sibling-Implemented Script Fading to Promote Play-Based Statements of Children with Autism

The researchers asked: can big brothers and big sisters run script fading at home?

They taught three neurotypical siblings to hand over, then fade, short play scripts.

The kids with autism were preschool age; sessions happened during normal toy play at home.

All three autistic children started saying new, fitting play lines right away.

The words stayed high even months after the last script was gone.

Siblings ran every step with near-perfect accuracy—no adult in the room.

Johnson et al. (2009) first showed moms and dads can do script fading; Akers simply swaps in brothers and sisters and gets the same strong jump in words.

Wichnick-Gillis et al. (2019) taught teachers to script-fade at school and saw gains spill over to siblings at home. Akers skips the school part and trains siblings first, proving the home team alone is enough.

Glugatch et al. (2021) also used siblings, but taught broad play tactics instead of scripts. Both teams saw more back-and-forth play, showing siblings can wear many helpful hats.

You now have two proven helpers in the same house: parents and siblings. If a brother or sister is willing, give them a short script, a quick rehearsal, and let the pair play. You free up parent time, build the sibling bond, and still get strong language gains that stick.
