CB are displayed by up to 60% of the adult IDD population. Example behaviors include physical aggression toward others including self (self-injurious) and property, and verbal aggression.

CB may be difficult to manage as it can cause stress to the individual, their families, and those around them. It can also lead to restrictive practices as well as loss of community based placements. This can lead to hospitalization and a limited access to long term care facilities.
