Cluster A Personality Disorders (Paranoid, Schizoid, Schizotypal)

What are cluster A personality disorders? Cluster A personality disorders are one of three clusters of personality disorders, and includes paranoid personality disorder, schizoid personality, and schizotypal personality disorder.

Paranoid Personality Disorder:

  • Distrustful and suspicious
  • These individuals are mistrustful and suspicious of the motivations and actions of others and are often secretive and isolated
  • They are emotionally cold and odd
  • They often take legal action against other people  due to thoughts that they are out to get them.


Schizoid Personality Disorder:

  • Schizoid Personality Disorder is characterized by a long-standing pattern of detachment from social relationships. A person with schizoid personality disorder often has difficulty expression emotions and does so typically in very restricted range, especially when communicating with others.
  • A person with this disorder may appear to lack a desire for intimacy, and will avoid close relationships with others. They may often prefer to spend time with themselves rather than socialize or be in a group of people. In laypeople terms, a person with schizoid personality disorder might be thought of as the typical “loner.”
  • They are absorbed in their own thoughts and feelings.
  • Remember schizOID liked to avOID.


Schizotypal Personality Disorder:

  • Schizotypal personality disorder is characterized by someone who has great difficulty in establishing and maintaining close relationships with others. A person with schizotypal personality disorder may have extreme discomfort with such relationships, and therefore have less of a capacity for them. Someone with this disorder usually has cognitive or perceptual distortions as well as eccentricities in their everyday behavior.
  • Individuals with Schizotypal Personality Disorder often have ideas of reference (e.g., they have incorrect interpretations of casual incidents and external events as having a particular and unusual meaning specifically for the person). People with this disorder may be unusually superstitious or preoccupied with paranormal phenomena that are outside the norms of their subculture.
  • Odd beliefs or magical thinking that influences behavior and is inconsistent with subcultural norms (e.g., superstitiousness, belief in clairvoyance, telepathy, or “sixth sense”; in children and adolescents, bizarre fantasies or preoccupations)
  • Odd thinking and speech (e.g., vague, circumstantial, metaphorical, overelaborate, or stereotyped)
  • Suspiciousness or paranoid ideation
  • Behavior or appearance that is odd, eccentric, or peculiar
