special education / peer-mediated interventions for autism

Peer-mediated interventions — training typically developing peers to model and prompt social interaction — reliably increase the social interaction of autistic students in inclusive settings and are among the better-supported social interventions, though effects are strongest for increasing interaction frequency and weaker for child-initiated social bids, with generalization and maintenance less consistently demonstrated.

For the Court

Established that peer-mediated interventions increase autistic students' social interaction in inclusive settings; effects on spontaneous initiations and generalization are weaker.

What This Claim Does NOT Say

Does not claim PMIs normalize or 'cure' autistic social behavior; they increase measured peer interaction, primarily in structured inclusive settings.
Effects are stronger for interaction frequency than for spontaneous child-initiated social bids, and generalization/maintenance are less consistently shown.
Much of the evidence is single-case research design; group RCT evidence is thinner.
Does not establish outcomes for any individual student; effects depend on peer training, setting, and fidelity.

Scope — Where It Holds

Supported by systematic reviews and an overview of 10 reviews concluding PMIs are "strongly supported" and most robust in inclusive settings (Watkins et al., 2015; Reichow et al., 2024), a single-subject meta-analysis showing high effectiveness for social interaction (Zhang & Wheeler, 2011), and a What-Works-standards meta-analysis showing moderate-to-large effects on social communication (Watkins et al., 2019). A single-case review cautions effects are weaker for child initiations and that generalization evidence is limited (Martinez et al., 2019).

Limits & Counter-considerations

Much evidence is single-case design rather than group RCT; effects are stronger for interaction frequency than spontaneous initiations; and generalization/maintenance are inconsistently demonstrated and depend on peer training and fidelity.
