Which of the following disorders is most closely related to impulsive and reckless behavior?

Conduct disorder is most closely related to impulsive and reckless behavior. This disorder typically manifests in children and adolescents and is characterized by a range of antisocial behaviors, including aggression toward people and animals, destruction of property, deceitfulness, or serious violations of rules. Individuals with conduct disorder frequently display a lack of empathy and disregard for social norms and the feelings of others, which can lead to impulsive actions that may put themselves and others at risk.

The core features of conduct disorder highlight not only impulsivity but also a pattern of behavior that is disruptive and harmful, differentiating it from the other listed disorders.

Hysterical personality disorder, while it can involve dramatic behaviors, does not specifically focus on impulsiveness akin to conduct disorder. Anxiety disorder involves excessive worry and fear, leading to avoidance behaviors rather than impulsivity. Adjustment disorder involves a reaction to a stressor that leads to emotional or behavioral symptoms but does not inherently include the impulsive and reckless behaviors associated with conduct disorder. Similarly, adjustment disorder does not portray a pattern of behavior that would consistently manifest as impulsivity, making conduct disorder the most relevant choice for this question.
