A child with a complex trauma history may be easily triggered or “set off” and is more likely to react very intensely. The child may struggle with self-regulation (i.e., knowing how to calm down) and may lack impulse control or the ability to think through consequences before acting. As a result, complexly traumatized children may behave in ways that appear unpredictable, oppositional, volatile, and extreme.
A child who feels powerless or who grew up fearing an abusive authority figure may react defensively and aggressively in response to perceived blame or attack, or alternatively, may at times be overcontrolled, rigid, and unusually compliant with adults. If a child dissociates often, this will also affect behaviour. Such a child may seem “spacey”, detached, distant, or out of touch with reality.
Complexly traumatized children are more likely to engage in high-risk behaviours, such as self-harm, unsafe sexual practices, and excessive risk-taking such as operating a vehicle at high speeds. They may also engage in illegal activities, such as alcohol and substance use, assaulting others, stealing, running away, and/or prostitution, thereby making it more likely that they will enter the juvenile justice system.
