  • not wanting or enjoying close relationships
  • almost always preferring solitary activities
  • having little or no interest in sexual activity with others
  • enjoying few or no activities
  • lacking close friends
  • being indifferent to others’ praise
  • emotional detachment

Is there a test for schizoid personality disorder?

A mental health professional can diagnose schizoid personality disorder based on your symptoms.

In the United States, clinicians will use the symptoms listed in the DSM-5-TR to diagnose schizoid personality disorder. To receive this diagnosis you will have a consistent pattern of social detachment and a limited range of emotional expression present from early adulthood.

What triggers schizoid personality disorder?

Schizoid personality disorder is a lifelong behavior pattern that stems from childhood. As such, there are no specific triggers and the exact causes are unknown.

There may be a genetic component, but according to a 2021 report, specific genes have not been found. Brain chemistry may also play a role, but research has not confirmed this.

According to the DSM-5-TR, there may be a higher prevalence of schizoid personality disorder in relatives of people with schizophrenia or schizotypal personality disorder.
