Which personality disorder is characterized by excessive emotionality and attention-seeking behavior?

Histrionic personality disorder is characterized by a pattern of excessive emotionality and attention-seeking behavior. Individuals with this disorder often display a high level of emotional expressiveness and may use their physical appearance to draw attention to themselves. They tend to be overly concerned with their appearance and may become uncomfortable if they are not the center of attention. Their actions may seem theatrical or exaggerated, and they often seek approval and reassurance from others. These traits lead to a significant impact on their interpersonal relationships and social functioning.

In contrast, borderline personality disorder is marked by instability in mood, self-image, and interpersonal relationships, but it does not focus primarily on attention-seeking behavior. Narcissistic personality disorder involves a grandiose perception of self-importance and a need for admiration rather than the emotionality and need for attention seen in histrionic personality disorder. Schizotypal personality disorder is primarily characterized by social and interpersonal deficits along with cognitive or perceptual distortions, rather than emotionality or attention-seeking traits. This distinction makes histrionic personality disorder the most fitting choice for the characteristics described.
