The development and maintenance of friendship in high-functioning children with autism: maternal perceptions.

Bauminger et al. (2003) asked moms of high-functioning kids with autism about their children's friends.

The survey wanted to know how many friends the kids had, how often they met, and where they played.

The children had fewer friends and shorter playdates than typical kids.

When they did have a friend without disabilities, the meet-ups almost always happened at home, not at school.

Bauminger et al. (2008) watched the same kind of kids and saw that mixed pairs played more like typical friends than pairs of two autistic kids. This backs up the 2003 moms' view that typical peers matter.

Chamberlain et al. (2007) mapped classroom networks and found autistic kids sat on the edge even in regular classes. Together these studies show friendships are scarce both in and out of school.

Chang et al. (2016) looked at preschoolers and found only one in five had a classroom friend. The pattern starts early and stays steady.

Mandelberg et al. (2014) gave parents friendship coaching and the kids kept more playdates three years later. The sparse baseline in 2003 helps explain why training helps.

You now know autistic friendships are rare and home-based. Use this when you write social goals. Push for playdates after school, not just peer time in class. Track who the friend is and where they meet. If parents say "no friends," believe them and start teaching friendship skills right away.
