Symptoms of Schizoid Personality Disorder

Rashmi Nemade, Ph.D. & Mark Dombeck, Ph.D., edited by Kathryn Patricelli, MA

person on bench People with Schizoid personality disorder are detached from society. They tend to be lifelong loners who come across as emotionless, cold or distant. They tend to prefer activities by themselves, rather than ones that involve others. They have few social interactions other than with relatives. They almost never develop intimate romantic relationships or even friendships. Although they share some negative symptoms in common with some people who have schizophrenia, they do not experience the psychotic behavior of hallucinations, delusions and loss of reality.

To be diagnosed with this disorder, a person must display four or more of the following symptoms:

  • Doesn't want or enjoy close relationships, including being a part of a family
  • almost always chooses solitary activities
  • has little or no interest in sexual experiences with another person
  • takes pleasure in few, if any, activities
  • doesn't have any close friends other than first-degree relatives (parents and siblings)
  • doesn't seem to be affected by the praise or criticism of others
  • shows emotional coldness, detachment, or very little emotion

These symptoms must not happen only as part of Schizophrenia, bipolar disorder or major depressive disorder with psychotic features, another psychotic disorder, or autism spectrum disorder. They must also not be caused by another general medical condition.
