Children with Autism Spectrum Disorder (ASD) Engage in More Verbal Aggression with Greater Intensity than Others

Quetsch and colleagues compared 450 autistic children to 432 neurotypical controls based on caregiver reports of aggressive behavior. Their analysis of results indicated that, across development, autistic children engaged in more verbal aggressive behavior with greater intensity than neurotypical children, although the degree of difference diminished as the children grew older.

Aggressive Behavior by Youth with Autism Spectrum Disorder (ASD) Is Influenced by the Environment

To what extent is the aggressive behavior of youth with Autism Spectrum Disorder (ASD) moderated (or aggravated) by attributes of their environment? Brown and colleagues tried to answer this question based on caregiver reports for 511 ASD youth. Overall, their data indicated that demographic and environmental factors accounted for up to 40% of the variance in children’s aggressive behavior. The main factors influencing reported aggressive behavior were:

Family income
The child’s age and social communication skills
Parental distress arising from having to deal with a difficult child

Besides these factors, the researchers also found a slight effect of family warmth as measured by the Family Environment Scale and Caregiver-Child Dyad Satisfaction, but this factor barely accounted for an additional one percent of the observed total variance.
