Histrionic personality disorder (HPD) is defined by the American Psychiatric Association as a personality disorder characterized by a pattern of excessive emotionality and attention-seeking, including an excessive need for approval, usually beginning in early adulthood. These individuals are lively, dramatic, enthusiastic, and flirtatious.

They may express strong emotions with an impressionistic style, and be easily influenced by others. Associated features may include egocentrism, self-indulgence, continuous longing for appreciation, and persistent manipulative behavior to achieve their own needs.

People with this disorder are usually able to function at a high level and can be successful socially and professionally. People with histrionic personality disorder usually have good social skills, but they tend to use these skills to manipulate other people and become the center of attention.

Histrionic personality disorder may affect a person's social or romantic relationships or their ability to cope with losses or failures.

They often fail to see their own personal situation realistically, instead tending to dramatize and exaggerate their difficulties. They may go through frequent job changes, as they become easily bored and have trouble dealing with frustration. Because they tend to crave novelty and excitement, they may place themselves in risky situations. All of these factors may lead to greater risk of developing depression.

Additional symptoms include:

    Exhibitionist behavior.
    Constant seeking of reassurance or approval.
    Excessive dramatics with exaggerated displays of emotions.
    Excessive sensitivity to criticism or disapproval.
    Proud of own personality, unwillingness to change and any change is viewed as a threat.
    Somatic symptoms, and using these symptoms as a means of garnering attention.
    A need to be the center of attention.
    Low tolerance for frustration or delayed gratification.
    Rapidly shifting emotional states that may appear superficial or exaggerated to others.
    Tendency to believe that relationships are more intimate than they actually are.
