All of the following are symptoms of conduct disorder except.

A. Stabilization phase. The stabilization phase occurs after the acute phase, when psychotic symptoms begin to improve with treatment. During this phase, the focus is on reducing symptom severity, medication adjustment, and preventing relapse.

B. Maintenance phase. The maintenance phase follows stabilization and involves long-term management to prevent relapse. During this phase, symptoms are either in remission or significantly reduced, and the goal is to ensure medication adherence, therapy, and social reintegration.

C. Prodromal phase. The prodromal phase precedes the acute phase and is marked by early warning signs such as social withdrawal, decreased motivation, mild paranoia, and subtle cognitive changes. It may last weeks to years before full-blown psychotic symptoms appear.

D. Acute phase. The acute phase is the period of full-blown psychotic symptoms, including hallucinations, delusions, disorganized speech, and impaired functioning. This is the most severe phase, often requiring hospitalization and intensive treatment to stabilize the patient.

A. Argumentative. Oppositional defiant disorder (ODD) is characterized by a pattern of defiant, hostile, and argumentative behavior toward authority figures. Children with ODD frequently argue with adults, refuse to comply with rules, and deliberately provoke others.

B. Resentful. Children with ODD often display persistent resentment and anger, particularly when they feel they have been wronged. They may hold grudges and struggle to forgive perceived slights, leading to ongoing conflicts with parents, teachers, or peers.

C. Aggressive toward animals. Aggression toward animals is not a symptom of ODD but is a key feature of conduct disorder (CD). Children with conduct disorder engage in severe violations of social norms, including cruelty to animals, destruction of property, and physical aggression toward people. ODD, in contrast, involves defiant and disruptive behaviors without serious violations of others' rights.

D. Vindictive. A vindictive attitude is one of the diagnostic criteria for ODD. Children with ODD may seek revenge, retaliate excessively, or intentionally annoy others to provoke a reaction. This behavior is often fueled by feelings of frustration and perceived injustice.
