Schizoid Personality Disorder

The schizoid personality rarely feels there is anything wrong with him/her; symptoms are an indifference to social relationships and a limited range of emotional expression.


The word personality describes deeply ingrained behavior patterns and the way individuals perceive, relate to, and think about themselves and the world. Personality traits are enduring patterns of perceiving, relating to and thinking about the environment and oneself that are exhibited in a wide range of social and personal contexts. A personality disorder has the characteristics of an enduring pattern of inner experience and behavior that deviates markedly from the expectations of the individual's culture, inflexibility and pervasiveness, an onset in adolescence or early adulthood stability over time and causing significant impairment in functioning or internal distress. Personality disorders are not isolated, atypical episodes of maladaptive behavior.

Schizoid personality disorder is a pattern of indifference to social relationships, with a limited range of emotional expression and experience. The disorder manifests itself by early adulthood through social and emotional detachments that prevent people from having close relationships. People with it are able to function in everyday life, but will not develop meaningful relationships with others. They are typically loners and may be prone to excessive daydreaming as well as forming attachments to animals. They may do well at solitary jobs others would find intolerable. There is evidence indicating the disorder may be the start of schizophrenia, or just a very mild form of it. People with schizoid personality disorder are in touch with reality unless they develop schizophrenia.


  • Takes pleasure in few, if any, activities
  • Does not desire or enjoy close relationships, including family
  • Appear aloof and detached
  • Avoid social activities that involve significant contact with other people
  • Almost always chooses solitary activities
  • Little or no interest in sexual experiences with another person
  • Lacks close relationships other than with immediate relatives
  • Indifferent to praise or criticism
  • Shows emotional coldness, detachment or flattened affect
  • Exhibits little observable change in mood

People with schizoid personality disorder maintain contact with reality. Also, men may be more likely to have this disorder than women.


Though the cause of personality disorders isn't known, both genetics and environment are suspected to play a part in its development. Some mental health professionals speculate that a bleak childhood where warmth and emotion were absent contributes to the development of the disorder. A higher risk for schizoid personality disorder in families of schizophrenics suggests that there is greater genetic susceptibility to develop this disorder might be inherited.

Those with schizoid personality disorder do not have schizophrenia, but it is thought that many of the same risk factors in schizophrenia may cause schizoid personality disorder. Relatives are not thought to be at risk for developing this disorder.

Diagnostic Evaluation

A psychological evaluation may be performed, and questionnaires and personality tests aid in the diagnosis. Symptoms must not occur solely during a schizophrenic episode for schizoid personality disorder to be deemed.


People with this disorder rarely seek treatment, and little is known about which treatments work. Talk therapy may not be effective, because people with schizoid personality disorder have difficulty relating well to others. Therefore, treatment can be difficult because of initial reduced capacity or desire to form a relationship with a health professional. A non-intrusive support group can alleviate feelings of solitude, and fears of social interactions and close relationships. Individual therapy, in most cases, has proven relatively ineffective and often temporarily addresses immediate conditions instead of seeking to terminate the disorder entirely.


Medications are not usually recommended for schizoid personality disorder. However, they are sometimes used for short-term treatment of extreme anxiety states associated with the disorder. The presence of anxiety--usually caused by fear of other people--may mean that a diagnosis of the related Schizotypal Personality Disorder is more appropriate. 


Individual therapy that successfully attains a long-term level of trust may be useful in certain cases of schizoid personality disorder by giving patients an outlet to transform their false perceptions of friendships into authentic relationships. As a therapist-client relationship develops, a patient can start to reveal imaginary friendships and terrors of dependency. Individual psychotherapy can gradually affect the formation of a true relationship between the patient and therapist.

Long-term psychotherapy should not be pursued because of its poor treatment outcomes and the costs inherent in lengthy therapy. Instead, therapy should focus on simple treatment goals to alleviate current pressing concerns or stressors within the individual's life. Cognitive-restructuring may be proper to address certain types of clear, irrational thoughts which are negatively influencing the patient's behaviors. This therapeutic plan should be clearly defined at the onset of treatment. Stability and support are the keys to good treatment with someone who suffers from schizoid personality disorder. Care should be taken not to "smother" the person with Schizoid personality disorder and be able to tolerate possible "acting-out" behaviors.

Group therapy is another potentially effective form of treatment but it generally is not a good initial treatment.Although patients may initially withdraw from the therapy group, they often grow participatory as the level of comfort is gradually established. Protected by the therapist, who must safeguard schizoids from criticism by others in the group, patients have the chance to conquer fears of intimacy by making social contact in a supportive environment.

Social consequences of serious mental disorders—family disruption, loss of employment, and housing—are sometimes calamitous. Comprehensive treatment, including services existing beyond the formal treatment system, is crucial to ameliorate symptoms, assist recovery, and redress stigma. Self-help programs, family self-help, advocacy and services for housing and vocational assistance complement and supplement the formal treatment system.
