Tests and diagnosis

By Mayo Clinic Staff

Diagnosing schizoid personality disorder is usually based on an in-depth interview with your doctor about your symptoms as well as your medical and personal history. Your doctor may perform a physical exam to rule out other conditions that may be causing or contributing to your symptoms. If your initial visit is with a primary care doctor, you'll likely be referred to a mental health professional for further evaluation.

To be diagnosed with schizoid personality disorder, you must meet criteria in the Diagnostic and Statistical Manual of Mental Disorders (DSM), published by the American Psychiatric Association. Diagnosis of schizoid personality disorder includes four or more of these characteristics:

  • You neither desire nor enjoy close relationships, including being part of a family.
  • You almost always choose solitary activities.
  • You have little, if any, interest in sexual experiences with another person.
  • You take pleasure in few, if any, activities.
  • You don't have any close friends or confidants other than first-degree relatives.
  • You seem not to care about praise or criticism.
  • You seem emotionally cold, detached or unexpressive.

For schizoid personality disorder to be diagnosed, doctors need to rule out conditions with similar symptoms.
