Oppositional Defiant Disorder (ODD) is characterized by a recurrent pattern of negativistic, defiant, disobedient, and hostile behavior toward authority figures. This may be evident through frequent loss of temper, persistent arguments with adults, defiance of rules/requests, deliberate annoyance of others, frequent blame of others for one’s mistakes, and frequent displays of anger, resentment, spite, or vindication.
Conduct Disorder (CD) involves a repetitive and persistent pattern of behavior in which basic rights of others or major age-appropriate societal norms or rules are violated. This may be in the form of aggression to people and animals, destruction of property, deceitfulness or theft, and/or serious violation of rules.
Intermittent Explosive Disorder (IED) is characterized by difficulty controlling aggressive impulses which lead to behavioral outbursts which can be in the form of verbal aggression (e.g., temper tantrums, frequent elevated arguments) or behavioral aggression (e.g., damage to property or physical assault to individuals and/or animals). Outbursts are recurrent, out of proportion to the magnitude of the stressor, cause impairments in functioning, and are not pre-meditated.
Antisocial Personality Disorder Individuals with Antisocial Personality Disorder are characterized by a pattern of disregard for or violation of other people’s rights since adolescence. They exhibit a tendency to violate social norms, and may engage in behaviors that may lead to run-ins with the law. They may be involved in deception, lying, or conning for personal gain or pleasure. They have a tendency to be impulsive and/or aggressive, leading to physical altercations. They may have little awareness of personal or others’ safety. They lack a sense of responsibility, leading to failure to meet work demands or financial obligations. Furthermore, individuals with Antisocial Personality Disorder lack remorse and may rationalize negative consequences that they may have inflicted on others.
