Obsessive-compulsive disorder (OCD) is a mental health condition characterized by obsessive, intrusive thoughts that trigger anxiety (obsessions), and repetitive behaviors aimed at reducing that anxiety (compulsions). People with OCD experience obsessions and compulsions to an excessive or irrational degree, which interferes with daily functioning and causes significant distress. An example of a common OCD obsession is an excessive fear of germs and contamination.
Obsessions in OCD
Obsessions are recurrent, persistent, and unwanted intrusive thoughts, images, or urges that trigger intensely distressing feelings. Common obsessions in OCD include:
- Fear of contamination by germs, dirt, or illness
- Doubting one’s actions, like whether the stove is turned off
- Need for symmetry or exactness
- Forbidden or taboo thoughts, like aggressive or sexual images
- Excessive religious or moral doubt
Obsessions are ego-dystonic, meaning they are inconsistent with the person’s self-image and cause significant anxiety or distress. The individual does not want to have the obsessive thoughts but has little control over them.
Compulsions in OCD
Compulsions are repetitive behaviors or mental acts that a person with OCD feels driven to perform in response to an obsession. Common compulsions include:
- Excessive cleaning and handwashing
- Repeatedly checking locks, appliances, and switches
- Ritualistic behaviors like counting, tapping, or ordering items
- Excessive prayer or reassurance seeking
- Hoarding behaviors
Compulsions are aimed at reducing the distress triggered by obsessions or preventing some dreaded event. However, the compulsions are excessive or not realistically connected to the obsession. A person with OCD recognizes the compulsions as irrational but feels unable to resist performing them.
Fear of Contamination as an OCD Obsession
A common obsession seen in OCD is an extreme or irrational fear of contamination from germs, dirt, or illness. This is sometimes called contamination OCD. Individuals with this obsession are preoccupied with the idea that surfaces, objects, or people are dirty or contaminated by invisible germs or toxins. They may have excessive fears about catching a disease. This obsession triggers intense feelings of anxiety, disgust, or uneasiness.
Common compulsions linked to contamination fears
Some common compulsive behaviors aimed at reducing anxiety about contamination include:
- Excessive washing and cleaning
- Avoiding physical contact with perceived contaminants
- Repeated disinfecting of surfaces
- Seeking constant reassurance that things are clean
- Avoiding public places like restrooms
- Hoarding cleaning supplies, tissues, or paper towels
Despite efforts to ease their anxiety through these rituals, the fears and concerns return quickly. This leads to repeating the compulsions, often for hours at a time.
Examples of contamination obsessions
Here are some examples of obsessive contamination worries:
- Fear of touching objects like doorknobs, money, or handrails because they may be dirty
- Constant thoughts about germs being on kitchen or bathroom surfaces
- Worrying that clothes or dishes aren’t cleaned well enough
- Concern that hands are dirty even after excessive handwashing
- Fears of getting sick after being around other people who may be ill
- Worrying about contamination from chemicals, asbestos, or radiation
The OCD fears are excessive for the actual risks involved. For example, a person may repeatedly wash hands for an hour after brief contact with a public surface despite the low risk of illness. Or they may avoid eating for fear of contamination despite meticulous cleaning.
Treatment for Contamination OCD
OCD often causes significant impairment in daily life, but treatment options are available. The most effective treatment approaches include:
1. Cognitive-behavioral therapy (CBT)
CBT helps the individual learn to tolerate uncertainty about contamination and resist compulsive behaviors. Exposure therapy gradually exposes the person to feared objects to reduce anxiety.
2. Medications
Selective serotonin reuptake inhibitor (SSRI) antidepressants like fluoxetine help reduce OCD symptoms for many people.
3. Acceptance and commitment therapy (ACT)
ACT focuses on accepting obsessive thoughts without reacting to them. Mindfulness skills help reduce distress.
With proper treatment, individuals with contamination OCD can learn to manage their symptoms and improve their quality of life. Getting help early leads to the best outcome.
Case Examples of Contamination OCD
Below are two examples of people struggling with contamination obsessions and related compulsions:
Sarah’s case
Sarah is a 35-year-old teacher who spends about 4 hours a day on cleaning rituals. She constantly worries that her house is contaminated by invisible germs that could make her sick. Her daily compulsions include:
- Disinfecting doorknobs, countertops, and light switches repeatedly
- Washing kitchen utensils for over an hour until it “feels right”
- Showering three times a day and washing hands for 10 minutes at a time
- Cleaning any items that have been “contaminated” by other people
These rituals severely interfere with Sarah’s social and work life. She cannot eat meals prepared outside her home or touch objects in public places. She is often late for school after hours of cleaning each morning. Sarah recognizes her fears are excessive but cannot control them.
Andrew’s case
Andrew is a 27-year-old accountant debilitated by contamination obsessions related to the COVID-19 pandemic. He is consumed with thoughts that he will contract COVID and spreads it to his loved ones. His daily rituals include:
- Taking his temperature and checking for symptoms repeatedly
- Avoiding coworkers and public places, working isolated at home
- Disinfecting all packages that enter his house for over an hour
- Washing hands raw and chapped despite negative COVID tests
- Calling family members repeatedly to ensure they are not sick
Andrew’s extreme safety behaviors provide temporary relief from his obsessions but ultimately reinforce his fears. He wants to stop but cannot control his rituals.
Both Sarah and Andrew’s cases exemplify how contamination OCD severely interferes with normal functioning. With proper treatment, individuals like them can learn to manage their intrusive thoughts and live fuller lives.
