All of the following describes schizoid personality disorder except

A. Severe temper outbursts. Disruptive Mood Dysregulation Disorder (DMDD) is characterized by frequent, severe temper outbursts that are out of proportion to the situation. These outbursts can be verbal or physical and occur at least three times per week, persisting for one year or more.

B. Struggle to regulate emotions. Individuals with DMDD have difficulty managing emotions, particularly anger and frustration. This emotional dysregulation leads to persistent mood instability, which interferes with daily functioning at home, school, and in social settings.

C. Hyperactivity. Hyperactivity is not a core symptom of DMDD but is more commonly associated with Attention-Deficit/Hyperactivity Disorder (ADHD). While some children with DMDD may also have ADHD, DMDD primarily involves severe mood disturbances rather than impulsivity or excessive movement.

D. Chronic irritability. Persistent irritability is a hallmark of DMDD, with children and adolescents experiencing near-constant irritability between temper outbursts. Unlike episodic mood disorders like bipolar disorder, DMDD symptoms are chronic and ongoing without distinct mood episodes.

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.
