A Schizoid personality disorder is one of a group of conditions called “Cluster ‘A’ ” or eccentric personality disorders. People with these disorders often appear odd or peculiar. People with schizoid personality disorder also tend to be distant, detached, and indifferent to social relationships. They generally are loners who prefer solitary activities and rarely express strong emotion. Although their names sound alike and they might have some similar symptoms, a schizoid personality disorder is not the same thing as schizophrenia. Many people with a schizoid personality disorder can function fairly well, although they tend to choose jobs that allow them to work alone, such as night security officers, library, or lab workers.
What Are the Symptoms of Schizoid Personality Disorder?
People with a schizoid personality disorder often are reclusive, organising their lives to avoid contact with other people. Many never marry or may continue to live with their parents as adults. Other common traits of people with this disorder include the following:
- They do not desire or enjoy close relationships, even with family members.
- They choose solitary jobs and activities.
- They take pleasure in few activities, including sex.
- They have no close friends, except first-degree relatives.
- They have difficulty relating to others.
- They are indifferent to praise or criticism.
- They are aloof and show little emotion.
- They might daydream and/or create vivid fantasies of complex inner lives.
How Common Is Schizoid Personality Disorder?
It is difficult to accurately assess the prevalence of this disorder because people with schizoid personality disorder rarely seek treatment. Schizoid personality disorder affects men more often than women and is more common in people who have close relatives with schizophrenia. Schizoid personality disorder usually begins in late adolescence or early adulthood.
What Causes Schizoid Personality Disorder?
Little is known about the cause of schizoid personality disorder, but both genetics and environment are suspected to play a role. Some mental health professionals speculate that a bleak childhood where warmth and emotion were absent contributes to the development of the disorder. The higher risk for schizoid personality disorder in families of schizophrenics suggests that a genetic susceptibility for the disorder might be inherited.
How Is Schizoid Personality Disorder Diagnosed?
If symptoms of this personality disorder are present, the doctor will begin an evaluation by performing a complete medical history and possible physical exam. Although there are no lab tests to specifically diagnose personality disorders, the doctor might use various diagnostic tests to rule out physical illness as the cause of the symptoms. If the doctor finds no physical reason for the symptoms, he or she might refer the person to a psychiatrist or psychologist, health care professionals who are specially trained to diagnose and treat mental illnesses. Psychiatrists and psychologists use specially designed interview and assessment tools to evaluate a person for a personality disorder.
How Is Schizoid Personality Disorder Treated?
People with this personality disorder rarely seek treatment, because their thoughts and behaviour generally do not cause them distress. When treatment is sought, psychotherapy — a form of counselling — is the form of treatment most often used. Treatment likely will focus on increasing general coping skills, as well as on improving social interaction, communication, and self-esteem. Because trust is an important component of therapy, treatment can be challenging for the therapist, because people with schizoid personality disorder have difficulty forming relationships with others. Social skills training also can be an important component of treatment. Medication is generally not used to treat schizoid personality disorder itself. Drugs might, however, be prescribed if the person also suffers from an associated psychological problem, such as depression.
What Are the Complications of Schizoid Personality Disorder?
A lack of social interaction is the main complication of schizoid personality disorder. People with this personality disorder are rarely violent, as they prefer not to interact with people. Co-occurring conditions such as mood disorders, anxiety disorders, and other personality disorders may also be more common than in the general population.
What Is the Outlook for People With Schizoid Personality Disorder?
Although some of their behaviours might be odd, people with schizoid personality disorder are generally able to function in everyday life. However, they might not form meaningful relationships or have families of their own. Studies have shown they may sometimes experience social, financial and work disability.
Can Schizoid Personality Disorder Be Prevented?
There is no known way to prevent schizoid personality disorder.
