Do Those with Schizoid Personality Disorder Often Suffer from Addiction?
Those who have schizoid personality disorder are not detached from reality, only from social relationships. People with schizoid personality disorder usually have a hard time expressing their emotions. When they do, it is often with a detached monotone that can make it difficult for others to understand the emotions the person with schizoid personality disorder is feeling or trying to express.
Schizoid personality disorder is part of what psychology labels Cluster A personality disorders. They include:
- Schizotypal personality disorder
- Paranoid personality disorder
- Schizoid personality disorder
All three tend to be indicated by strange or eccentric behavior as well as many common symptoms and shared genetic and environmental risk factors that may lead to their development.
Specifics of Schizoid Personality Disorder
People with schizoid personality disorder (SPD) are generally not interested in developing close relationships and will actively avoid them. They express little interest in intimacy, sexual or otherwise, and endeavor to spend most of their time alone. They will often, however, form close bonds with animals. A person with schizoid personality disorder is often seen as the prototypical loner, shunning group activities and shutting themselves off from human contact.
Due to a lack of social interaction (however desired it may be), people with schizoid personality disorder exhibit a notable lack of social skills. This, combined with the underlying lack of desire for intimacy or friendship, means they generally have few friends, date little, and very rarely marry.
The social interactions they do have tend to arise out of social or familial pressure to conform to more normative behavior or the economic requirements of needing to interact with others on the job. In fact, they are often drawn to occupations that allow them to work on their own, such as musical instrument repair, software development, or long-haul trucking. The perfect job for a person with schizoid personality disorder would be lighthouse keeper.
Schizoid personality disorder is sometimes expressed in non-expression. In addition to having a flat affect, people with schizoid personality disorder may have an especially hard time expressing anger. Even when directly provoked, someone with schizoid personality disorder might react very coolly, belying what they may be feeling underneath. Even though a person with schizoid personality disorder may seem emotionless, they are still experiencing emotions.
Recognizing the Disorder
Schizoid personality disorder may begin to appear in childhood, but it usually doesn’t fully express itself until the late teens or early 20s. This is because personality disorders like SPD tend to require the establishment of personality into patterns of behavior, and the personalities of children and teens are constantly developing, changing, and maturing.
More men than women tend to experience schizoid personality disorder, and it’s generally thought that about 3.1 percent to 4.9 percent of people have the disorder.
The symptoms generally fall into two key areas: emotional coolness and lack of interest in people or activities. They include:
- Neither desiring nor enjoying close relationships, even with family members
- Failing to find pleasure in many – or any – activities others often enjoy
- Having little to no interest in sexual relationships
- Having no close friends or anyone to confide in other than a few close relatives
- Showing little to no reaction to criticism or praise
- Exhibiting a flat affect, detachment, and emotional coldness
It is usually a mental health professional with specific training, such as a psychologist or psychiatrist, who will diagnose a personality disorder such SPD since other clinicians, including internists and general practitioners, often lack the training required to make this sort of psychological diagnosis. Of course, a family physician may be consulted initially when a personality disorder is suspected, but that family physician should refer the person to a mental health professional for more accurate diagnosis.
People with schizoid personality disorder tend not to seek out treatment unless the condition begins to have a major harmful impact on their life. This will usually occur when coping resources reach their limits, and the stress of the disorder or other life events becomes too much to handle. Sometimes the condition is noticed if a person seeks treatment for another, related disorder, such as depression.
What Causes Schizoid Personality Disorder?
The short answer is that no one knows, but theories abound. The most commonly referenced hypothesis of the cause of schizoid personality disorder is the biopsychosocial model of causation. Basically, this suggests the causes are rather broad and touch many areas of a person’s life. They include biological and genetic factors, including family history of similar conditions. Social factors – including interaction in childhood with family, friends and other children – are also indicated as well as psychological factors, such as a person’s temperament, personality, and ability to deal with stress.
This suggests that no single factor – biological, social, or psychological – is solely responsible for the condition, but a complex and highly interrelated web of all three factors that must be considered. It seems that genetics play some role in schizoid personality disorder, and all the recognized personality disorders, as research suggests an increased risk among people whose parents or close relatives also have schizoid personality disorder.
A hypothesis referenced by Jeffrey Seinfeld in his book, The Empty Core: An Object Relations Approach to Psychotherapy of the Schizoid Personality suggests the disorder and others, including addiction, may be significantly sourced in early childhood through a lack of love and empathy, the need for which is seen as analogous to a newborn’s physiological need for oxygen. This causes the “empty core” of the book’s title, and the person with a personality disorder may try to fill that emptiness with drugs, alcohol, or food, or they may repress and dissociate the “needy self” by denying themselves social interaction (in the case of schizoid personality disorder) or food (in the case of bulimia).
Addiction and Schizoid Personality Disorder
Medical and psychiatric literature does not call out addiction or substance abuse as arising specifically out of schizoid personality disorder. It is not seen as a specific complication of the disorder. People with schizoid personality disorder seem to be at greater risk of developing schizotypal personality disorder or schizophrenia, as well as anxiety or depression, but addiction is not specifically listed as a complication.
However, anxiety and depression can all too often lead to a substance use disorder. In his book, Seinfeld further states that “drug addiction is the perfect intersection for schizoid and symbiotic experience.” The addiction functions as a substitute for human relations. Just as some with schizoid personality disorder create emotional attachments with animals or objects, some may create a relationship with an addiction, or use the addiction to eliminate the need for human interaction.
A study done in the UK of a sampling of treatment centers indicated that 37 percent of people seeking services for drug addiction and 53 percent seeking services for alcohol addiction were also found to have personality disorders. Schizoid personality disorder was not specifically isolated, so it’s unclear if those numbers would be higher or lower if only schizoid personality disorder was being studied. The Australian Department of Health states that “harmful alcohol and other drug use often co-occurs with personality disorders.”
How Is the Disorder Treated?
Schizoid personality disorder is approached at a treatment level from several different avenues. There are some difficulties in treatment for multiple reasons.
Because of the nature of the disorder, people with schizoid personality disorder are far less likely to seek treatment in the first place because it means meeting and interacting with other people. Since the primary treatment – as it is with all personality disorders – is therapy, that means not only interacting with another person, but interacting on a deep, honest, emotional level – something people with schizoid personality disorder avoid to as great a degree as possible.
Creating trust and rapport in a therapeutic relationship often takes quite a long time. Since those with schizoid personality disorder will seek to keep themselves detached from people in their lives, even their families, that rapport is exceedingly difficult to foster. Clinicians will focus their efforts even more closely on establishing a sense of security for their client.Group therapy, which can be beneficial in most instances in helping a person understand they aren’t alone in their struggles is less of an option for those with schizoid personality disorder. Patients have a hard time tolerating the impact of this intense social interaction. However, therapists Birgitte Thylstrup and Morten Hesse suggest in the American Journal of Psychotherapy that group therapy can lead to “less fear of intimacy by making social contact in a supportive, therapeutic environment.”
There are no medications approved to treat schizoid personality disorder, but doctors will sometimes prescribe antidepressants or anti-anxiety medications if those symptoms are also present.
Often, a person with schizoid personality disorder will come against a crisis of some sort or a problem that requires immediate action, and seek out a therapist for assistance in resolving that specific issue. But as soon as the problem is addressed to the patient’s satisfaction – or the patient determines no progress is being made – they will usually stop treatment.
If schizoid personality disorder co-occurs with a substance use disorder, this is called a dual diagnosis or co-occurring disorders. A National Survey on Drug Use and Health indicated that almost 8 million Americans had a mental health disorder and a substance use disorder concurrently.
When a substance use disorder co-occurs with schizoid personality disorder, or when it arises out of the anxiety or depression that can accompany schizoid personality disorder, comprehensive treatment is vital due to the long-term negative impacts of substance abuse.
A person with schizoid personality disorder may not feel they have a problem that needs medical or psychological intervention, but if they develop an addiction and begin to see its negative effects on their lives, they may be persuaded to enter treatment for the addiction. While in treatment, they will have the opportunity to address the underlying anxiety and depression that in itself may be caused by schizoid personality disorder. This would allow the person to then confront the condition they had not previously felt needed intervention or treatment.
