Cumulative risk effects in the bullying of children and young people with autism spectrum conditions.
Bullying surges suddenly when risk factors add up, so count the risks and act early.
01Research in Context
What this study did
The team asked teachers and parents to rate how often students with autism were bullied. They also counted each child’s risk factors, like behavior problems or regular classes instead of special-ed rooms.
By adding up the risks they gave every child a "cumulative risk score," then looked to see if higher scores meant more bullying.
What they found
Bullying did not rise in a straight line. Once a student had several risks, bullying shot up much faster.
Teacher reports showed this jump most clearly, meaning adults in school spotted the sudden leap in victimization.
How this fits with other research
Maïano et al. (2016) already showed that almost half of youth with autism face bullying. Hebron et al. (2017) now explain why some face even more: risk piles up and then bullying explodes.
Buse et al. (2014) and Zablotsky et al. (2014) listed single risk factors like older age or full-inclusion classes. The new paper stacks those same factors together and reveals their combined punch.
Deniz et al. (2026) followed the same kids over time and found many stay on a chronic bullying track. Their long view supports the 2017 warning: without help, high-risk students stay trapped.
Why it matters
If you tally each student’s risks, you can spot the ones nearing the danger zone before bullying spikes. Move high-score students to smaller groups, boost adult monitoring, or add social-skills plans. A quick count beats waiting for reports of new bruises or missing lunch money.

03Original abstract
Students with autism are more likely to be bullied than their typically developing peers. However, several studies have shown that their likelihood of being bullied increases in the context of exposure to certain risk factors (e.g. behaviour difficulties and poor peer relationships). This study explores vulnerability to bullying from a cumulative risk perspective, where the number of risks rather than their nature is considered. A total of 722 teachers and 119 parents of young people with autism spectrum conditions participated in the study. Established risk factors were summed to form a cumulative risk score in teacher and parent models. There was evidence of a cumulative risk effect in both models, suggesting that as the number of risks increased, so did exposure to bullying. A quadratic effect was found in the teacher model, indicating that there was a disproportionate increase in the likelihood of being bullied in relation to the number of risk factors to which a young person was exposed. In light of these findings, it is proposed that more attention needs to be given to the number of risks to which children and young people with autism spectrum conditions are exposed when planning interventions and providing a suitable educational environment.
