Oppositional defiant disorder

Children with Oppositional Defiant Disorder (ODD) display age-inappropriate amounts of stubbornness, are irritable, defiant, disobedient, and behave in a hostile manner. Individuals with ODD do not see themselves as angry, oppositional, or defiant and often justify their behaviour as reaction to circumstances/demands. Thus, the symptoms of the disorder become entangled with the problematic interactions with others.
