Add "oppositional defiant disorder" to the list
Oppositional defiant disorder is a childhood disorder that is characterized by negative, defiant, disobedient, and often hostile behavior toward adults and authority figures primarily. In order to be diagnosed, the behaviors must occur for at least a period of 6 months.
Oppositional defiant disorder (ODD) is characterized by the frequent occurrence of at least four of the following behaviors: losing ones temper, arguing with adults, actively defying or refusing to comply with the requests or rules of adults, deliberately doing things that will annoy other people, blaming others for his or her own mistakes or misbehavior, being touchy or easily annoyed by others, being angry and resentful, or being spiteful or vindictive.
Negativistic and defiant behaviors are expressed by persistent stubbornness, resistance to directions, and unwillingness to compromise, give in, or negotiate with adults or peers. Defiance may also include deliberate or persistent testing of limits, usually by ignoring orders, arguing, and failing to accept blame for misdeeds.
Hostility can be directed at adults or peers and is shown by deliberately annoying others or by verbal aggression (usually without the more serious physical aggression seen in conduct disorder).
