Personality Disorders Cluster C
Overview – Personality Disorders, Cluster C
Personality Disorders, Cluster C, involves a group of mental illnesses that involve long-term patterns of thoughts and behaviors that are unhealthy and inflexible. Cluster C disorders are known as the “anxious, fearful” cluster and include three disorders that share anxious and fearful features. They are characterized by:
- Avoidant behaviors (social inhibition, feelings of inadequacy, and hypersensitivity to negative evaluation).
- Obsessive-compulsive behaviors (preoccupation with orderliness, perfectionism, and mental and interpersonal control).
- Dependent behaviors (submissive, clinging, and fearful of separation).
There is a tendency for personality disorders within the same cluster to co-occur, meaning that an individual may be diagnosed with more than one personality disorder. Those diagnosed with Cluster C personality disorders may be seen by others as antisocial or withdrawn. They tend to behave in anxious or avoidant ways and often need things to be orderly and controlled.
As with other personality disorders, Cluster C demonstrates four defining characteristics In order to be diagnosed with a personality Disorder in Cluster C, the individual must exhibit at least two of the four defining characteristics:
- Distorted thinking patterns
- Problematic emotional responses
- Over- or under-regulate impulse control
- Interpersonal difficulties.
Information is presented about four types of Personality Disorders in Cluster C, one type each day for four days. These are:
Avoidant Personality Disorder
To be diagnosed with Avoidant Personality Disorder, the individual must exhibit at least four of seven criteria:
Avoids occupational activities involving significant interpersonal contact, due to fears of criticism, disapproval, or rejection
Is unwilling to get involved with people unless certain of acceptance
Shows restraint within intimate relationships due to fears of shame or ridicule
Preoccupied with fears of receiving criticism or rejection in social situations
Inhibited in new interpersonal situations due to feelings of inadequacy
Considers self as inferior to others, socially inept, or personally unappealing
Is unusually reluctant to take personal risks or to engage in any new activities because they may prove embarrassing
Dependent Personality Disorder
A diagnosis may be made based on an excessive and pervasive need to be taken care of that includes submissive, clinging, needy behavior due to fear of abandonment. This may be exhibited as:
Difficulty making routine decisions without input, reassurance, and advice
Requires others to assume responsibilities which they should be attending to.
Fear of disagreeing with others and risking disapproval.
Difficulty starting projects without support from others.
Excessive need to obtain nurturance and support from others,
Feels vulnerable and helpless when alone.

Unrealistic preoccupation with being left alone and unable to care for the self.
Obsessive-Compulsive Personality Disorder
Some forms of obsessive-compulsive personality disorder also present as obsession with work and productivity to the point of complete exclusion of leisure activities and interpersonal relationships. Individuals presenting in this manner will often refuse to delegate tasks unless others will follow the same methods of doing things, despite being overwhelmed by their workload. Their devotion to perfectionism and rigid control can make it difficult for them to function. Obsessive-Compulsive Personality disorder involves an excessive need for orderliness, neatness, and perfection. Unfortunately, the individual tries to impose their personal standards for orderliness, neatness, and perfection on others, which can be stressful for all types of relationships.
