Stephen constantly brags to his teammates that he is the best player on the team. He dreams of making the big play that wins the game, but in reality the opposite often occurs. Stephen even believes his teammates would never win another game if he quit the team. Stephen may have which personality disorder?

Dependent personality disorder involves a strong reliance on others for emotional and decision-making support. Individuals with this disorder typically exhibit submissive behavior and an excessive need to be taken care of, which contrasts with Stephen’s self-aggrandizing attitude and belief in his superiority.

Avoidant personality disorder is marked by social inhibition, feelings of inadequacy, and hypersensitivity to negative evaluation. Stephen's bravado and boastful claims indicate a lack of avoidance; rather, he seeks attention and validation, which is inconsistent with the characteristics of this disorder.

Antisocial personality disorder involves a pattern of disregard for the rights of others and social norms, often manifesting as deceitfulness and impulsivity. While Stephen may exhibit some self-centered behaviors, he does not display the manipulative or harmful characteristics that are typical of antisocial personality disorder.
