Peer influence on problem behaviors among students with intellectual disabilities.
Peers alone do not sway problem behavior in special-ed classes; you need structured peer programs to see real change.
01Research in Context
What this study did
The team watched students with intellectual disability in special-education classrooms. They asked: do classmates make each other’s problem behaviors better or worse?
No extra program was added. The researchers just tracked natural day-to-day behavior and looked for peer-to-peer effects.
What they found
Overall, peers did not push problem behaviors up or down.
Small, quiet effects did show up. In mixed-ability rooms, students felt less anxiety and talked more when peers modeled calm, clear communication.
How this fits with other research
Groves et al. (2019) ran the Good Behavior Game in similar rooms. They saw disruptive behavior drop and friendly talk rise. The new study saw almost no peer pull without an active program, so the Game’s rules and points likely create the change, not just peer presence.
Laposa et al. (2017) built trained peer networks for high-schoolers with severe disabilities. Friendships lasted two semesters. Their active peer-to-peer teaching fits the idea that structure, not chance peer contact, drives gains.
McKenna et al. (2019) found almost no solid evidence for academic fixes for students with emotional disturbance in general-ed rooms. Together, these papers warn: hoping peers will naturally help is weak; planned, taught peer contact is what works.
Why it matters
If you run a self-contained room, do not count on peer osmosis to curb anxiety or boost talk. Instead, script roles, set clear group goals, and reward prosocial moves. A quick Monday tweak: pick one student to model calm breathing before a task and reinforce the class when anyone copies.

03Original abstract
BACKGROUND: Students with intellectual disabilities (ID) exhibit increased rates of problem behaviors compared to those without ID. AIMS: Given the evidence of peer influence in typical development, we examined the impact of classmates' characteristics on problem behaviors of students with ID. We expected higher levels of problem behaviors in special needs classrooms will influence individual development of such behaviors. METHODS: A longitudinal design with measurements at the beginning and the end of a school year was applied. Staff reported on problem behaviors of 1125 students with ID (69 % boys; age 11.30 years,SD = 3.75) attending 16 Swiss special needs schools. RESULTS: The peer influence hypothesis was not supported for an overall problem behavior score. However, exploratory analyses suggested that peer influence did occur for the domains anxiety, problems in relating socially, and communication disturbances (not disruptive/antisocial, self-absorbed and other types of problem behaviors). The influence of classmates on anxiety was lower when there was more variability in anxiety within the classroom. The development of communication skills benefitted from attending a classroom that was heterogeneous in the level of communication problems. CONCLUSION: Our results suggest that the influence of peers on problem behaviors in special needs schools is not universal but varies between domains and depends on classroom characteristics.
