A client who challenges rules and lacks personal responsibility is most closely related to which disorder?

The traits of challenging rules and lacking personal responsibility are most aligned with antisocial personality disorder. This disorder is characterized by a disregard for others' rights and societal norms, often leading to manipulative or deceitful behavior. Individuals with antisocial personality disorder may exhibit impulsivity, lack of remorse, and difficulty in maintaining relationships, reflecting their challenges with personal responsibility.

Narcissistic personality disorder is more associated with an inflated sense of self-importance and a need for admiration, rather than a blatant disregard for rules or personal accountability. Borderline personality disorder typically involves intense emotional experiences and unstable relationships rather than rule-challenging behavior. Lastly, paranoid personality disorder primarily focuses on pervasive distrust and suspicion of others rather than rule-breaking or irresponsibility. Therefore, antisocial personality disorder is the most fitting diagnosis for a client exhibiting those specific characteristics.
