When children with disruptive behaviour seem angry, it may be the result of unresolved circumstances. They are quick to blame others for mistakes. They generally have poor peer relationships and often display behaviours that alienate them from their peers. In addition, these children may have an unusual response to positive reinforcement or feedback: when given public praise, for example, they may respond by destroying or sabotaging the project for which they were given recognition.
Some children develop disruptive behaviours as a result of the stress and frustration resulting from experiences such as divorce, death, loss of family, or family disharmony. Disruptive behaviour may also be a way of dealing with depression or the result of inconsistent rules and expectations for behaviour.
