By far, this is the most difficult type. Fortunately, their numbers are small. Some other subtypes may have characteristics similar to this type, but not all. He sees the world from an adversarial point of view. The world is against him. Everyone is out to get him and no one can be trusted. The only coping strategy he has is to maintain a good "offense" and so he attacks before others do or say anything. Even the slightest issue is a source of provocation. Once he begins his attack he can be relentless, and keep coming at you until he is exhausted. If he is younger, you might have the stamina to deal with this. If he is older, the police are often called. These children are unusually bright. Their thinking involves violent themes and their actions are hostile and aggressive to others. They want to "fire, murder, devour, shoot, destroy" people who go against them in any situation, no matter how trivial. Typically, they receive multiple diagnoses, often oppositional defiant disorder or some other psychiatric condition such as bipolar disorder.
Recommended Approach: Since this is the most difficult type by far, you must take extraordinary means to help these children. Placating your child or "walking on eggshells" will only give you a momentary reprieve. Most parents of these children refrain from physical interventions, but may be using a good deal of restraining techniques. This again is a temporary solution. To begin with, you must seek professional help, in terms of both medication and behavioral interventions. You must maintain calmness in your interactions with these children. Only the most powerful reinforcers may be of some use. A highly structured environment with firmness is needed, along with great persistence and patience. Dealing with this type is something you don't do alone.
