Which personality disorder is marked by anxiety?

Paranoid personality disorder is characterized by a pervasive distrust and suspicion of others. Individuals with this disorder often feel that others are out to harm or deceive them, leading to significant anxiety in interpersonal relationships. They may constantly be on guard, interpreting benign remarks as hostile, which contributes to their anxiety and emotional distress. This constant anxiety can manifest in various ways, affecting their social interactions and overall functioning.

In contrast, other personality disorders listed, such as antisocial, narcissistic, and borderline personality disorders, feature different core characteristics. Antisocial personality disorder is more associated with a disregard for the rights of others and a lack of empathy, which does not predominantly revolve around anxiety. Narcissistic personality disorder focuses on grandiosity and a need for admiration, often masking underlying vulnerabilities but not primarily characterized by anxiety. Borderline personality disorder does involve intense emotions and fear of abandonment, which can cause anxiety; however, it is more focused on mood instability and interpersonal challenges than the chronic distrust central to paranoid personality disorder.

Thus, the clarity and pervasive anxiety linked with paranoid personality disorder make it the correct choice among the options provided.
