The inclusion of siblings in social skills training groups for boys with Asperger syndrome.

Researchers ran an 8-week social skills group for boys with Asperger syndrome. Half the groups included a brother or sister; the other half did not.

Kids practiced reading faces, taking turns, and handling teasing. The team tested the boys in the lab and asked parents and teachers to rate them before and after.

Boys got better at spotting emotions and social cues on lab tasks. Parents and teachers saw no change at home or on the playground.

Having a sibling in the room made no difference either way. The lab skills did not travel to real life.

Porter et al. (2008) warned that most social-skills studies for kids with Asperger lack solid proof. Our null parent/teacher data line up with that warning.

Amanollahi et al. (2025) looks like a contradiction: they saw better social give-and-take when siblings attended an autism-only support group. The key difference is Zahra’s siblings met alone, then went home to practice, while L et al. kept siblings side-by-side inside every lesson. Separate support plus home practice may work better than co-teaching every drill.

Kalyva (2010) helps explain the rater gap: kids with Asperger, parents, and teachers often disagree on social skill levels. If we want real-world gains, we need measures that happen where the skills should show up—lunchroom, recess, Xbox chat.

Stop adding siblings to groups just for the sake of it. Instead, teach the peer at home exactly what to prompt and reinforce, then track data in natural spots like the kitchen table or park. Pick outcome tools that happen in those same spots—short parent checklists, video clips, or peer play counts. Lab scores feel good but they can hide the true generalization picture.
