How is schizoid personality disorder diagnosed?

A doctor or mental health professional can diagnose schizoid personality disorder by conducting a thorough physical, behavioral, and emotional assessment. Psychiatrists, psychologists, and psychotherapists are usually the most qualified people to provide this service. The professional may request a physical exam and blood test to rule out medical conditions that may cause  symptoms that mimic those of schizoid personality disorder. If no medical cause is found, the person will be screened to see if they display any of the following symptoms:

• Person appears numb, or lacks a normal range of emotions
• Does not respond to compliments or critiques
• Has a low sex drive or low desire for intimacy
• Has few friends, or none at all
• Does not experience pleasure in daily life experiences
• Prefers to be alone almost all of the time
• Does not desire friendships or close familial relationships

When a person clearly shows four or more of the above traits, he or she is likely to be diagnosed with schizoid personality disorder.
