What Are Cluster C Personality Disorders?

Personality disorders are patterns of thought, feeling, and behavior that significantly deviate from what is considered typical in a given culture. These patterns affect the way an individual interacts with others and perceives the world around them. Cluster C personality disorders are one of the three main categories of personality disorders, and they are characterized by anxiety and fear-based behavior. People with these disorders often have difficulty with relationships and are prone to intense worry or fear of rejection. Let’s dive into the different types of Cluster C personality disorders and how they manifest.


The Three Types of Cluster C Personality Disorders

Cluster C disorders include avoidant, dependent, and obsessive-compulsive personality disorders (OCPD). These disorders are marked by anxious and fearful behavior. Let’s take a closer look at each:

1. Avoidant Personality Disorder (AVPD)

People with avoidant personality disorder tend to feel socially inept, inadequate, and overly sensitive to criticism or rejection. These individuals usually have a strong desire for close relationships but are held back by a fear of being judged or humiliated. They often isolate themselves due to this anxiety and may avoid social situations where they feel they might be negatively evaluated.

Common characteristics of someone with avoidant personality disorder include:

  • Fear of rejection or criticism in social situations

  • Intense feelings of inadequacy

  • Avoiding work or social activities due to fear of embarrassment

  • Low self-esteem

2. Dependent Personality Disorder (DPD)

Dependent personality disorder is characterized by an overwhelming need to be taken care of. Individuals with DPD often have difficulty making decisions without the input or reassurance of others. They may have difficulty standing up for themselves and may go to great lengths to avoid conflict, sometimes to the detriment of their own needs. This can lead to submissive or clingy behavior in relationships, and a fear of abandonment is often a central concern.

People with dependent personality disorder may display:

  • Difficulty making decisions without input from others

  • A fear of being abandoned or left alone

  • A tendency to stay in unhealthy relationships

  • A need for excessive reassurance and approval from others

3. Obsessive-Compulsive Personality Disorder (OCPD)

It’s important to distinguish obsessive-compulsive personality disorder (OCPD) from obsessive-compulsive disorder (OCD). While both share some traits, OCPD is a personality disorder, whereas OCD is an anxiety disorder. People with OCPD are preoccupied with orderliness, perfectionism, and control. They may have difficulty relaxing and letting go of control, leading to inflexible behavior and a rigid sense of how things should be done. These individuals can become frustrated or angry if their plans or routines are disrupted.

Symptoms of obsessive-compulsive personality disorder include:

  • A preoccupation with orderliness, rules, and schedules

  • Perfectionism that interferes with task completion

  • Overly focused on work and productivity

  • Difficulty delegating tasks or trusting others to do them correctly

Causes and Risk Factors

Like most personality disorders, the exact causes of Cluster C personality disorders are not fully understood. However, a combination of genetic, environmental, and social factors may contribute to their development. Trauma, childhood abuse, or overprotective parenting styles can increase the risk of developing these disorders. Genetics may also play a role, as family members of people with Cluster C disorders are more likely to develop similar conditions.

Treatment Options for Cluster C Personality Disorders

While personality disorders can be challenging, they are treatable with the right approach. Treatment typically involves psychotherapy, which helps individuals understand their thoughts and behaviors and learn coping strategies. Cognitive-behavioral therapy (CBT) is particularly effective in addressing the anxious and fearful patterns associated with Cluster C disorders. In some cases, medication may be prescribed to address specific symptoms such as anxiety or depression.

  1. Cognitive Behavioral Therapy (CBT): This form of therapy helps individuals identify and change negative thought patterns, leading to healthier behaviors and better emotional regulation.

  2. Dialectical Behavior Therapy (DBT): DBT focuses on teaching coping mechanisms for managing emotional distress and improving interpersonal relationships.

  3. Medication: Selective serotonin reuptake inhibitors (SSRIs) and other medications may be prescribed to help manage anxiety and depressive symptoms.


Cluster C personality disorders can significantly impact a person’s quality of life and relationships. Individuals with these disorders often experience chronic anxiety and fear, which can make it difficult for them to engage fully in the world around them. However, with the right treatment, including therapy and sometimes medication, people with Cluster C personality disorders can learn to manage their symptoms and build healthier relationships.
