Behavioural disorder

Getting angry quickly, suddenly for no reason. Wanting to hit or kick someone. If someone says something you don’t like, you want to scream and curse. You can’t do anything about it, but it keeps happening. You also frequently lie or you break things on purpose. Everyone can get really angry from time to time for no reason, but if you are prone to this it may be that you exhibit a lot of aggressive behaviour.

What is behavioural disorder?

Everyone gets extremely angry from time to time, but when you are prone to this and your parent and friends also notice this it may be that your behaviour is too aggressive. For example, you might get extremely angry all of a sudden because your parents want you to do something you don't want to do or because someone at school says something to you. Your preferred response is to curse or hit the person.
Often, however, you have no idea at all where this feeling comes from and you are really bothered that others don't like you anymore because of your anger issues.

There is a distinction in behavioural disorder between two kinds of aggressive behaviour:

  • Oppositional defiant behaviour: This means that you can’t stand it when someone tells you that you have to do something or, as it may be, that you can’t do something. This makes you extremely angry. For example, if your mother says that you can't go outside, you want to run away as fast as you can and you feel like cursing at her or kicking her. This behaviour is known of as Oppositional Defiant Disorder (ODD). 
  • Antisocial behaviour: When you act antisocially, you get not only angry, but you also often do things – like screaming, teasing, lying and fighting – that you ought not to do. Occasionally, you also might destroy or steal things. You often believe that you are right to get angry and that the other person is entirely to blame. This behaviour is known of as Conduct Disorder (CD).

What causes this kind of behaviour?

Aggressive behaviour can be hereditary, meaning that you are born with a certain tendency to get angry quickly. For example, you may be hyperactive and you therefore get angry quickly. You can’t do anything about this.

You may also develop aggressive behaviour due to things happening in your environment at the time or if you experienced something bad in the past. For example, big problems and fights might be common in your family.

How common is behavioural disorder?

About two out of every 100 children in the Netherlands exhibit aggressive behaviour.
