Cluster B Personality Disorders and Traits

Personality disorders are often considered severe mental health conditions that affect a person’s thinking patterns, feelings, and behaviors. Untreated personality disorders can cause disruption and turmoil in a person’s life, potentially leading to failed or strained relationships, friendships, job performance, or schooling. Unfortunately, personality disorders can be hard to diagnose because those who have them often do not believe anything is wrong with their behavior, or they do not see the need for treatment.

Personality disorders are categorized into three clusters (Cluster A, Cluster B, and Cluster C) according to the Diagnostic and Statistical Manual of Mental Disorders. Of the ten personality disorders, four belong within the cluster B personality disorders.

Read on to learn more about the characteristics, diagnosis, and treatment of cluster B personality disorders. 

What Is a Cluster B Personality Disorder?

Cluster B personality disorders are characterized by dramatic, emotional, intense, or erratic behaviors [1]. Although each of the four cluster B personality disorders exhibits different symptoms, they are all tied together by a commonality of the individual displaying volatile emotionality and unpredictable behavior.  A single, clear diagnosis of cluster B personality disorders is rare, especially because symptoms can overlap.

What are the Cluster B Personality Disorders?

The four cluster B personality disorders are Antisocial, Borderline, Histrionic, and Narcissistic Personality Disorder. We’ll review them in more detail below.

Antisocial Personality Disorder (ASPD)

People who have antisocial personality disorder have a long-term pattern of disregarding or violating the emotional and physical rights of others. They often exhibit a lack of empathy, impulsivity, irresponsibility, manipulation, arrogance, or a lack of remorse. These behaviors can lead to more severe actions, such as criminal behavior or substance abuse. The prevalence rate for antisocial personality disorder is about 3.3%. Research also suggests that ASPD is approximately three times more prevalent among males than females [2].

Borderline Personality Disorder (BPD)

Borderline personality disorder is characterized by chronic mood instability, unpredictable or unstable behavior, difficulty maintaining personal relationships, and frequent bouts of self-harm or suicidal ideation or behavior. People with BPD have difficulty regulating and managing their emotions, leading to issues with relationships and their sense of self. They often feel a fear of abandonment, explosive anger, or impulsiveness. Studies show that BPD is diagnosed about twice as often in females as in males, though this may be partly skewed by referral and diagnostic patterns [2].

Histrionic Personality Disorder (HPD)

Individuals who have histrionic personality symptoms always feel the need to be the center of attention and constantly seek external approval and validation. They are often prone to extremely seductive behavior, even if the situation is inappropriate. HPD can also cause a person to be easily influenced by others, display overly dramatic behavior, and communicate in vague or exaggerated terms.

Narcissistic Personality Disorder (NPD)

NPD is a mental health condition in which the affected person exhibits a long-term, persistent pattern of grandiose behavior, including an inflated sense of self-importance, a need for admiration, or a lack of empathy. People with narcissistic personality disorder often feel a strong sense of entitlement and superiority, so much so that they are willing to exploit or manipulate others in order to uphold and further this unfounded belief. Narcissists experience frequent envy and disregard for others. 

What Are the Traits of Cluster B Personality Disorders?

Although all cluster B personality disorders have their own unique symptoms, there are some common traits that are shared among them, including:

• Emotional instability
• Impulsivity
• Interpersonal challenges
• manipulation

How Cluster B Differs from Other Personality Disorders

To understand the specific challenges of Cluster B, it’s helpful to look at how these conditions compare with other personality disorders categorized in Clusters A and C:

• Cluster A Personality Disorders: marked by social withdrawal, eccentric beliefs, and cognitive distortions. These include: Paranoid Personality Disorder, Schizoid Personality Disorder, and Schizotypal Personality Disorder.
• Cluster C Personality Disorders: defined by anxious or fearful behaviors and chronic insecurity. These include: Avoidant Personality Disorder, Dependent Personality Disorder. Obsessive Compulsive Personality Disorder.

Diagnosing Cluster B Personality Disorders

Diagnosing personality disorders can be challenging, particularly because individuals with these disorders often don’t recognize that anything is wrong. This is also true for those with cluster B personality disorders.

Once a person begins treatment with a mental health professional, a diagnosis may be made. To accurately diagnose a cluster B personality disorder, your provider might ask questions related to:

• Your perception of yourself, others, and events
• The appropriateness of your emotional reactions
• Your interactions and relationships with others, especially in close connections
• Your impulse control

The clinician may also request to speak with someone who knows you well, such as a spouse or family member, as their insights can greatly aid in making an accurate diagnosis. In addition to interviews and questionnaires, your doctor will refer to the latest edition of the Diagnostic and Statistical Manual of Mental Disorders, published by the American Psychiatric Association, which outlines the diagnostic criteria for personality disorders, including the duration and severity of symptoms.

After a diagnosis is made, plans for treatment and symptom management can begin.

Treating Cluster B Personality Disorders

Cluster B personality disorders are considered incurable, as are all personality disorders, including clusters A and C. However, medication and psychotherapy can help treat them and improve the patient’s quality of life.

Medication

There are no medications specifically approved for treating personality disorders; however, some mental health professionals may prescribe medications to help manage associated symptoms. These can include antidepressants, anti-anxiety medications, mood stabilizers, or antipsychotics. While medications can ease some symptoms, psychotherapy appears to be more effective, particularly for cluster B personality disorders [3].

Psychotherapy

Psychotherapy, often referred to as talk therapy, involves patients meeting with a therapist to explore their thoughts, feelings, and behaviors. Treatment often focuses on identifying and modifying harmful personality traits that contribute to relational instability and emotional dysregulation.

Several types of psychotherapy may be beneficial for treating cluster B personality disorders, including:

• Cognitive Behavioral Therapy (CBT)
• Dialectical Behavior Therapy (DBT)
• Psychoanalytic Therapy
• Psychoeducation

The primary aim of talk therapy is to equip individuals with cluster B personality disorders with tools to enhance their quality of life. This includes helping them identify challenges, learn from experiences, and become more aware of their emotional distress.

How to Help Someone Who Has a Cluster B Personality Disorder

If you know someone with a cluster B personality disorder or suspect that a close friend or family member may have a personality disorder, there are several ways you can offer support. Keep in mind that individuals with personality disorders often do not recognize their condition, especially if it hasn’t been formally diagnosed, or they may feel they don’t need help.

If you think someone is undiagnosed, gently encourage them to visit their primary care physician, who can refer them to a psychiatrist. People may be more inclined to listen to a doctor’s advice rather than that of a friend or family member.

For those who have a diagnosed personality disorder, here are some ways to support them during their treatment:

• Take care of yourself first. You can’t support others without prioritizing your own well-being.
• Be patient. Change takes time.
• Don’t take things personally. Their behavior often reflects the disorder.
• Use “I” statements. This keeps communication respectful.
• Acknowledge their effort. Encouragement goes a long way.
• Offer practical help. Assist with appointments or transportation.
• Join a session if invited. Your support can make a huge difference.
