Histrionic Personality Disorder
- Histrionic personality disorder (HPD) is one of the cluster B personality disorders (PDs).
- HPD is characterized by persistent and excessive emotionality and attention seeking that deviate from cultural and social norms and produce functional impairment or distress.
- With the advent of the DSM-5, an alternative model is being promulgated that may come to define diagnosis as impairment in personality function AND the presence of pathologic traits. Using this alternative model, a person previously diagnosed with HPD would be diagnosed with PD—trait-specified. The alternative model does not include the HPD diagnosis. Poor construct validity has been suggested for the diagnostic category of HPD.
- No data available on the incidence of HPD
- HPD typically begins to manifest by early adulthood and persists throughout life in the absence of treatment (2).
Etiology and Pathophysiology
- Both genetic and environmental factors play a role in development of HPD.
- Biosocial learning theory: According to the biosocial model in psychology, persons might develop HPD from inconsistent or inappropriately low parental attention. For example, a parent might respond only when the child has intense emotional affect, eventually leading the individual to unconsciously learn to be excessively emotional to draw attention to themselves.
Commonly Associated Conditions
- Depression, anxiety, panic disorder
- Somatic symptom disorder
- Body dysmorphic disorder
- Posttraumatic stress disorder
- Dissociative disorders
- Substance use disorder
- HPD can co-occur with other PDs, particularly other cluster B PDs (antisocial, borderline, narcissistic) (2).
