Updated: Jan 22, 2020

In our last post, we talked briefly about the different clusters of personality disorders, today, we will be exploring more about the personality disorders in Cluster A.


Personality disorders in Cluster A are characterised by eccentric or unusual behaviour or thoughts. They include paranoid, schizoid and schizotypal personality disorders (Mayo Clinic, 2016).

 

Paranoid Personality Disorder

According to Cherry (2019), paranoid personality disorder is “a chronic and pervasive condition characterized by disruptive patterns of thought, behavior, and functioning”.


Some symptoms that people with paranoid personality disorder may have are (Cherry, 2019):

  • Having persistent and chronic suspicion and distrust of others

  • Thinking that others lied to, deceived or exploited them

  • Believing that they have untrustworthy and unfaithful friends, family and romantic partners

  • Having outbursts of rage when they believed they have been tricked

  • Usually seen as cold, secretive, jealous or serious

  • Searching for secret meanings in conversations and actions

 

Schizoid Personality Disorder

Schizoid personality disorder is “an uncommon condition in which people avoid social activities and consistently shy away from interaction with others” (Mayo Clinic, 2017).


People with schizoid personality disorder might (Mayo Clinic, 2017):

  • Favour being alone and doing activities by themselves

  • Not enjoy or desire close relationships

  • Have little need for sexual relationships

  • Feel that they are unable to feel pleasure

  • Have trouble expressing their feelings and reacting suitably to situations

  • Seem to be cold, indifferent or lack a sense of humour

  • Seem to lack motivation and goals

  • Not have any reaction to praise or criticism from others

 

Schizotypal Personality Disorder


According to Martel (2016), people with this disorder may have behaviours and mannerisms that seem strange to others. While schizotypal personality disorder part of the schizophrenia spectrum, people with this disorder usually do not have psychosis.


Symptoms of schizotypal personality disorder include (Martel, 2016):

  • Having weird behaviours or way of thinking

  • Having strange beliefs

  • Being uncomfortable in social situations

  • Lacking emotions or having inappropriate emotional reactions

  • Having vague and odd speech or rambles on

  • Lacking close friends

  • Having severe social anxiety
