Description of Schizoid Personality Disorder (SPD)

People with a schizoid personality are introverted, withdrawn, and solitary. They are emotionally cold and socially distant. They are most often absorbed with their own thoughts and feelings and are fearful of closeness and intimacy with others. They talk little, are given to daydreaming, and prefer theoretical speculation to practical action. Fantasizing is a common coping (defense) mechanism.

Although they experience little anxiety, people with schizoid personality disorder can still see the difference between themselves and the rest of the world. One patient with SPD noted that he could not fully enjoy the life he has because he feels that he is living in a shell. Furthermore, he stated that his inability distressed his wife. According to Beck and Freeman, patients with schizoid personality disorders consider themselves to be "observers rather than participants in the world around them."

Schizoid Personality Disorder is relatively rare and is estimated to occur in just 1% of the population.

Diagnostic Criteria for Schizoid Personality Disorder (SPD)

Full description of Schizoid Personality Disorder. Definition, signs, symptoms, and causes of Schizoid Personality Disorder.Does not occur exclusively during the course of Schizophrenia, a Mood Disorder With Psychotic Features, another Psychotic Disorder, or a Pervasive Developmental Disorder and is not due to the direct physiological effects of a general medical condition. Note: If criteria are met prior to the onset of Schizophrenia, add "Premorbid," e.g., "Schizoid Personality Disorder (Premorbid)."

DSM-IV does say that a person with Schizoid Personality Disorder may feel sensitive to the opinions of others and may even feel lonely but cannot do anything about the loneliness due to the disorder.

Causes of Schizoid Personality Disorder (SPD)

While scientists haven't found the causes of personality disorders, it is generally suspected that they result from a combination of genetic, biological and environmental factors. Although people with Schizoid Personality Disorder do not have Schizophrenia, it appears that many of the same risk factors in Schizophrenia also apply to Schizoid Personality Disorder.
