9 Histrionic Personality Disorder Statistics for 2026
Histrionic personality disorder, or HPD, is a personality disorder marked by intense emotions (doctors call this excessive emotionality) and attention-seeking behaviors. It belongs to Cluster B personality disorders, a group that also includes antisocial, borderline, and narcissistic personality disorder.
To be diagnosed with HPD under the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), a person needs to meet at least five of the following diagnostic criteria, starting in early adulthood and showing up across many parts of life:
- Feeling uncomfortable when they’re not the center of attention.
- Acting in ways that are inappropriately flirty or sexually seductive with others.
- Emotions that change quickly and don’t feel deep or lasting.
- Using their looks to grab attention.
- Speaking in a vague, dramatic way without much real detail.
- Being overly dramatic or theatrical (sometimes called self-dramatization).
- Being suggestible, meaning easily talked into things or swayed by others.
- Thinking relationships are closer than they really are.
Below is a set of statistics on HPD, followed by other established facts about the disorder that don’t come with a specific number. Each links to its source.
Methodology
Every fact and figure here comes from peer-reviewed studies, government health surveys, and trusted references such as StatPearls, the Merck Manual, and PsychDB, prioritizing the original study or survey over websites that repeat a statistic without citing its source.
Every number was checked against its original source before inclusion. Several numbers found in secondary write-ups actually traced back to a different study than the one credited, or weren’t supported by that source at all; those were fixed or removed. Where two studies disagreed, both are shown with their sources rather than picking one as “correct.”
Numbers with a specific figure are kept separate from broader facts that don’t reduce to one number, like the typical age HPD starts.
HPD is also one of the least-studied disorders in epidemiology, the research tracking how common a condition is and who it affects. Several figures here, including the NESARC survey, come from data collected in 2001-2002, and no newer national survey has measured HPD since. However, it’s still listed as its own diagnosis in the DSM-5-TR, the manual’s most recent update. Where a stronger, more recent source was available, like a 2019 study combining data from many countries, that’s used as the main figure, with older numbers shown for comparison.
Statistics on Histrionic Personality Disorder
1. Worldwide, an estimated 0.6% of people have histrionic personality disorder
A 2019 study combining data from 46 studies across 21 countries estimated that about 0.6% of people worldwide have HPD. The Merck Manual also notes that HPD affects fewer than 2% of the general population.

2. An estimated 3.8 million American adults, or 1.8% of the population, have HPD
A major U.S. survey conducted in 2001-2002, interviewing more than 43,000 adults, found that 1.8% of American adults, or roughly 3.8 million people at the time, met the criteria for HPD, with no meaningful gender difference.
A later re-analysis using different diagnostic rules found a much lower estimate (0.27%), showing how much prevalence figures can shift depending on how “having HPD” is defined.

3. HPD is more common among people already in psychiatric care, ranging from 1-6%, and as high as 15% in some studies
Studies generally estimate 1-6% of people already receiving psychiatric care meet the diagnostic criteria for histrionic personality disorder. Newer studies using broader, trait-based definitions or focusing on specific groups report rates as high as 10-15%, illustrating how prevalence varies depending on how HPD is measured.

4. A study spanning seven countries and roughly 114,000 people found HPD prevalence of 0.83%
Combining data from about 114,000 people across seven Western countries, researchers found 12.16% of people had some kind of personality disorder, and 0.83% specifically had HPD.

5. A twin study found that genetics explain about 67% of the risk for HPD specifically
Researchers studied 92 identical and 129 non-identical twin pairs to see how much of each personality disorder’s risk comes from genes versus environment. For HPD, genes accounted for about 67% of the trait differences, higher than schizoid (29%), paranoid (28%), and avoidant (28%), though significantly lower than narcissistic (79%) and obsessive-compulsive (78%).

6. Women are diagnosed with HPD about four times more often than men, but the actual rates may be similar
Older studies found women diagnosed with HPD far more often than men. But a major 2001-2002 U.S. survey found no real difference between men and women, matching an earlier Baltimore population study that also found HPD affects both at close to the same rate (about 2.1%).
This suggests HPD in men may be underdiagnosed, and that the gap may be related to inconsistencies in how doctors label behavior such as sexual forwardness in men and women rather than a true difference in prevalence by gender.

7. In one of the largest recent HPD treatment studies, 82% of patients were women, despite men and women having similar underlying rates of the disorder
In the same 159-patient psychotherapy study referenced below, 82% of participants were women, matching earlier findings that women are diagnosed with HPD about four times as often as men.
That contrasts with epidemiological surveys finding the disorder affects men and women at close to the same rate, suggesting potential bias in diagnosis and the possibility that women are more likely to seek treatment, not necessarily more likely to have HPD.

8. HPD is under-studied compared to other personality disorders, with a group of just 159 patients counting as one of the leading studies on the disorder
One of the relatively few published treatment studies focused specifically on HPD included 159 participants receiving a form of talk therapy.
By comparison, treatment studies for disorders such as borderline personality disorder often enroll several hundred participants, and evidence is frequently pooled across multiple randomized trials involving thousands of patients.
The relatively small size of the HPD evidence base highlights how much less attention the disorder has received from researchers.

9. HPD is the personality disorder most strongly linked to divorce
Researchers studied 1,241 adults ages 55-64 in St. Louis to examine how symptoms of all 10 personality disorders related to the number of divorces. Personality disorder symptoms were measured three ways: through a clinical interview, self-report, and reports from someone who knew the participant.
In these analyses, larger positive numbers indicate a stronger link to divorce, while negative numbers indicate a link to fewer divorces.
After accounting for gender and overlap between personality disorders, HPD was the strongest predictor of divorce in every analysis, with effect sizes of .29, .24, and .18. Researchers proposed that histrionic charm and a need for closeness may work early in a relationship but grow harder to sustain, feeding repeated cycles of marriage and divorce.
For comparison, paranoid personality disorder showed a much weaker link (.12, .09, and .08), while avoidant personality disorder was linked to fewer divorces (−.09, −.08, and −.07). Lower divorce rates among patients with APD may be due to those traits making leaving a marriage less likely even when unhappy.
Antisocial personality disorder (ASPD) was linked to divorce only once other traits were factored in.

Other Facts About Histrionic Personality Disorder
HPD typically begins in the late teens or early twenties
Like most personality disorders, HPD involves a long-standing pattern of behavior starting by early adulthood, showing up across many areas of life, not just occasionally.

Both genes and childhood environment appear to play a role in HPD
Genetics, childhood experiences, and environment are all thought to contribute, though research on its etiology, meaning what causes it, remains limited. Twin studies suggest genes matter, but no specific gene has been linked to it.

Childhood trauma, including child abuse, neglect, and certain parenting styles, is linked to a higher chance of developing HPD
Child abuse or neglect, especially sexual abuse, is linked to higher risk, backed by a 2023 study. Inconsistent, overly permissive parenting is also linked to higher risk, as is a parent who behaves in a dramatic or inappropriately sexual way.

Surviving a sexual assault is linked to HPD traits, separate from a person’s underlying temperament
A study of college students found sexual assault linked to HPD’s more sexualized traits, even after accounting for temperament, which was the factor researchers had focused on previously.

HPD very often shows up alongside other personality disorders, especially borderline, narcissistic, and dependent personality disorder
In a study of psychiatric day hospital patients, most people with HPD also had at least one of those three, a pattern called comorbidity. This overlap is common enough that some question whether HPD should be its own diagnosis.

People with HPD tend to also struggle with depression, anxiety, physical symptoms with no clear medical cause, and substance use
Research shows higher-than-average rates of depression (sometimes diagnosed as major depressive disorder), anxiety disorders, unexplained physical symptoms (somatic symptom disorder), and substance use disorders.
One study found teenagers with histrionic traits were more likely to develop binge-eating and purging behaviors later in life.

People with personality disorders, including HPD, are more likely to think about or attempt suicide than the general population
Clinical professionals typically watch for warning signs throughout treatment.

Several other conditions must be ruled out before settling on an HPD diagnosis, a process called differential diagnosis
HPD’s dramatic behavior and quick mood swings can resemble bipolar disorder, though HPD doesn’t involve the reduced need for sleep seen in a manic episode. Its physical complaints can also resemble somatization disorder, conversion disorder, or illness anxiety disorder.

Talk therapy focused on understanding underlying emotional patterns is the main treatment for HPD, and there isn’t strong evidence for other approaches
This approach, known as psychodynamic psychotherapy or psychodynamic therapy, focuses on a strong, trusting patient-therapist relationship.
There’s no medication approved for HPD specifically, and little is known about how well cognitive behavioral therapy (CBT) works for it, since most personality disorder research has focused on borderline personality disorder.
Doctors may prescribe antidepressants for co-occurring depression or anxiety, and some programs include group therapy alongside individual sessions.

HPD usually lasts a lifetime and improvement usually requires treatment
People do best when treatment also addresses other conditions they’re dealing with and helps stabilize relationships and daily life.
Source: StatPearls, NCBI Bookshelf
Stigma, and the fact that people with HPD often don’t see anything wrong with their own behavior, make it harder for them to get treatment
People with HPD often see their own behavior as normal, so they’re less likely to seek help on their own. Family members of people with personality disorders also often face judgment and stigma when trying to get their loved one help.

What These Histrionic Personality Disorder Statistics Reveal
- Epidemiology: HPD affects roughly 0.6-1.8% of the population, with historical diagnosis rates skewed toward women, though large surveys find the disorder actually affects men and women at close to the same rate.
- Development of histrionic personality disorder: Genetics appear to play an unusually large role, with one twin study estimating heritability around 67%, while childhood trauma, child abuse, neglect, and certain parenting styles also raise risk.
- Personality traits and symptoms of HPD: Core traits include excessive emotionality, attention-seeking behaviors, self-dramatization, suggestibility, and sexually seductive behavior, which strain relationships and are linked to a higher rate of divorce.
- Comorbid conditions and substance use: People with HPD show elevated rates of depression, anxiety, somatic symptom disorder, and substance use disorders, often alongside other Cluster B personality disorders.
- Environmental factors: Child abuse, neglect, inconsistent or overly permissive parenting, and even surviving a sexual assault are linked to higher risk, alongside genetic predisposition.
- Mental illness and psychiatric disorders: HPD frequently co-occurs with borderline, narcissistic, and dependent personality disorder, and carries an elevated risk of suicidal thoughts and attempts.
- Consequences and prognosis: HPD is typically lifelong without treatment, contributes to a higher likelihood of divorce, and remains one of the most under-researched and under-treated personality disorders, in part because of stigma and low self-recognition.
