Social anxiety predicts aggression in children with ASD: clinical comparisons with socially anxious and oppositional youth.

Robertson et al. (2013) compared three groups of kids: children with high-functioning autism, kids with social anxiety disorder, and kids with oppositional or conduct problems.

They gave parents and kids questionnaires about social fears and aggressive behavior. Then they looked for patterns between fear levels and aggression in each group.

Children with autism showed the same amount of aggression as the oppositional group and the same social fears as the anxious group.

For kids with autism only, aggression was highest when social fears were very low or very high. In the middle fear range, aggression dropped. This U-shaped pattern did not appear in the other two groups.

Amore et al. (2011) surveyed parents and found that 68% of youth with autism showed aggression toward caregivers. Their work set the stage by showing aggression is common, while E et al. added the twist that social anxiety level shapes who is most at risk.

Aller et al. (2023) tracked autistic youth across childhood and found physical aggression fades with age while verbal aggression lingers. E et al.'s curvy link between social fear and aggression may help explain why some kids stay verbally aggressive into the teen years.

Shyu et al. (2026) later showed that higher social anxiety predicts poorer quality of life in autistic adolescents. Together with E et al., this suggests assessing social fears early could improve both behavior and life satisfaction.

When a child with autism shows aggression, check how they feel about social situations. Very low fear can mean they miss social cues that normally curb hitting or yelling. Very high fear can trigger fight-or-flight outbursts. Aim for the middle ground: teach social skills and coping tools so fear stays moderate and aggression drops.
