Histrionic Personality Disorder

Histrionic Personality Disorder (HPD)

*(Cluster B Personality Disorder – DSM-5)*

A pervasive pattern of excessive emotionality and attention-seeking behavior, characterized by theatricality, exaggerated emotions, and a need to be the center of attention.

DSM-5 Diagnostic Criteria

Requires ≥5 of the following:

1. Discomfort when not the center of attention.
2. Inappropriately seductive/provocative behavior (not limited to romantic contexts).
3. Rapidly shifting, shallow emotions (appear exaggerated or insincere).
4. Consistently uses physical appearance to draw attention.
5. Speech is excessively impressionistic (lacks detail, overly dramatic).
6. Self-dramatization, theatricality, exaggerated emotional expression.
7. Suggestible (easily influenced by others/fads).
8. Considers relationships more intimate than they are (e.g., calls acquaintances “best friends”).

Key Features

Behavioral Patterns:

✔ Attention-seeking antics (e.g., exaggerated stories, sudden emotional outbursts).
✔ Seductive/flirtatious behavior (even in professional settings).
✔ Impressionistic speech (e.g., “The meeting was amazing!” without specifics).

Cognitive Style:

• “If I’m not noticed, I don’t matter.”
• “Being average is unbearable.”

Emotional Experience:

• Emotions shift rapidly but lack depth.
• Frustration when others receive attention.

Epidemiology & Comorbidity

• Prevalence: ~2% (more frequently diagnosed in women; potential gender bias).
• Onset: Late teens/early adulthood.
• Common Comorbidities:
  • Borderline PD (shared impulsivity/emotional dysregulation).
  • Somatization disorder (physical symptoms for attention).
  • Major depressive disorder (when attention-seeking fails).

Differential Diagnosis

Condition	Distinguishing Features
Borderline PD	Fear of abandonment + self-harm (vs. HPD’s focus on attention).
Narcissistic PD	Grandiosity + lack of empathy (vs. HPD’s warmth/sociability).
Bipolar Disorder	Episodic mood swings with functional impairment (vs. HPD’s constant dramatics).

Etiology

Biological:

• Genetic overlap with other Cluster B disorders.
• Possible dysregulation in serotonin/dopamine systems.

Psychological:

• Childhood reinforcement for “cute” or dramatic behavior.
• Parental modeling of exaggerated emotionality.

Cultural Factors:

• More prevalent in cultures that reward expressiveness.

Treatment Approaches

1. Psychotherapy (First-Line)

• Cognitive Behavioral Therapy (CBT):
  • Challenge beliefs like “I must be adored to be valuable.”
  • Replace dramatic behaviors with authentic communication.
• Schema Therapy: Addresses schemas like Approval-Seeking.
• Group Therapy: Provides feedback on social boundaries.

2. Pharmacotherapy (For Comorbid Symptoms Only)

• SSRIs (e.g., Fluoxetine): For comorbid depression/anxiety.
• Mood Stabilizers (e.g., Lamotrigine): If emotional lability is severe.

3. Social Skills Training

• Practice nuanced emotional expression.
• Learn to tolerate being “ordinary.”

Prognosis

• Moderate improvement with therapy (if patient acknowledges issues).
• Risks without treatment:
  • Chaotic relationships.
  • Professional setbacks (e.g., seen as “unserious”).

Clinical Pearls

✔ Avoid reinforcing dramatic behavior (e.g., don’t overreact to crises).
✔ Use humor carefully (HPD patients may feel mocked).
✔ Set clear boundaries (e.g., “I can’t respond to texts after 9 PM”).
