Aggression is a common occurrence in households of children with disabilities. This can be overwhelming for most parents. The purpose of this post is to identify variables that affect aggression, along with basic preventative and response strategies. While these are strategies commonly used in various settings, a descriptive assessment or functional analysis should be conducted by a Board Certified Behavior Analyst (BCBA) to identify the function of aggression. After identifying the function, the BCBA can then assist in identifying individualized antecedent and response strategies, accompanied with functional replacement behaviors to decrease aggression and improve functional skills.
