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 pervasive and excessive need to be taken care of, leading to submissive and clinging behaviors. Stephen's behavior does not exhibit dependence on others for support or guidance; instead, he shows an inflated self-image and a belief in his superior abilities, which contradicts the characteristics of dependent personality disorder.

Avoidant personality disorder is marked by social inhibition, feelings of inadequacy, and hypersensitivity to negative evaluation. Stephen's behavior, which includes boasting about his skills and seeking attention, indicates a desire for validation rather than avoidance of social situations. Therefore, his actions do not align with the avoidance traits typical of this disorder.

Antisocial personality disorder is characterized by a disregard for the rights of others and social norms, often leading to deceitful or manipulative behavior. While Stephen's behavior may seem self-centered, it is not indicative of the manipulative or harmful tendencies associated with antisocial personality disorder. His focus on self-importance does not align with the violation of others' rights typical of this condition.
