Emotional contamination OCD is a subtype of obsessive-compulsive disorder (OCD) that can be difficult to recognize. It centers around the fear that certain people, places, or objects are “contaminated,” emotionally or mentally. This often leads the person affected to believe they must avoid these triggers or perform rituals to avoid negative outcomes. 

Rather than perceiving contamination in a traditional physical sense, individuals with emotional contamination OCD experience it as an internal feeling—like moral impurity or taboo thoughts. For example, they may not have physically touched something harmful but feel that having a certain thought makes their environment “contaminated.” This can cause them to feel “dirty” or even “evil”, with the belief that these feelings will spread to others, objects, or situations around them.

Emotional contamination is a common feature of OCD, with studies suggesting that as many as 46% of people with OCD experience these types of feelings.

What emotional contamination looks like

Though the emotional contamination feels internal, individuals with this type of OCD often engage in physical compulsions to try to “wash away” these intrusive thoughts. They may fear that without cleansing themselves–such as through excessive hand-washing, showers, or rewashing clothes–the thoughts might become true. This need for certainty keeps the OCD cycle going, often leading to hours of compulsive behaviors, chapped hands, and endless re-cleaning.

Others may instead attempt to deal with emotional contamination by spending countless hours in prayer and confession, hoping to feel “clean” again. They may seek constant reassurance that they are not a bad person. However, this reassurance is short-lived, reinforcing the belief that they cannot trust their own sense of self, further intensifying their anxiety and self-doubt.

OCD can be extremely creative in the way it attaches meaning to certain situations. For example, someone who comes into contact with a person who has cheated on their partner may later have intrusive thoughts about their own potential for infidelity. As a result, they may avoid all contact with anyone connected to infidelity, including people who have been involved in cheating or even media that depicts unfaithfulness. The avoidance becomes more widespread, leading to isolation and further anxiety.

Emotional contamination of objects, people, places, and more 

Emotional contamination can make a person attach this “unclean” feeling to objects, people, or situations. This can cause significant distress, as the person believes that even minor contact with these triggers will lead to emotional contamination.

Take the case of Allie*, a patient I worked with several years ago who struggled with intrusive thoughts she deemed morally wrong. Her obsession centered around eating. If she had a thought she considered “impure,” she began to feel that what she was eating would then become contaminated. This belief led her to feel ashamed and sickened, preventing her from finishing the meal.

For Allie, the color red became a major trigger. She believed it signified the presence of blood in her food, which caused her to have intrusive thoughts that she had harmed someone in her past. Despite knowing that there was no actual blood in her food, the possibility alone made her feel so ashamed and sickened that she could no longer eat red foods. Over time, this fear spread to almost all foods.

Though Allie understood logically that the food wasn’t contaminated, her OCD-driven anxiety made her feel that she could never be completely certain. This uncertainty led to repeated avoidance of the foods associated with these intrusive thoughts, which trapped her in a cycle of fear and isolation.

Another person I treated, John*, had a fear that one of his loved ones would die in a car accident, triggered by a specific compulsive routine: getting dressed. When he dressed in certain clothes, intrusive thoughts would flood his mind. He would then immediately change his clothes to neutralize these thoughts, and eventually, he discarded clothing entirely after such episodes. Over time, John had very few items of clothing that felt “safe” to wear. 

While John recognized that his clothing had no connection to whether someone would be in a car accident, OCD’s whispers of “what if” or “just in case” kept him locked in a cycle of doubt and fear that led to compulsions and avoidance. 

People with emotional contamination OCD often feel relief after engaging in compulsions, but that relief is temporary. The obsessive thoughts will keep coming back until they are faced head-on. To combat these unwanted thoughts, people with OCD must decide that they will not engage in the compulsion and see what will happen. That’s the only way that the brain can learn that there is no real danger or real connection between the feared thought and the resulting behavior.

Magical thinking and emotional contamination 

Many people with emotional contamination fears also struggle with magical thinking–the belief that one’s internal thoughts, beliefs, actions, wishes, or words can influence what happens in the world around them. It also includes superstitious beliefs.

For example, a child with magical thinking OCD may feel the need to say things in a certain manner or repeat a particular prayer or phrase before bed each night to keep their loved ones safe. The child will have a need to say certain words or prayers the same way each time, or they may say it a specific number of times or repeatedly until it feels “just right.” They may say it in their head, but because OCD causes doubt, they’ll question themselves. This will often lead them to restart the whole process again, which can result in endless amounts of time being spent on this compulsion. 

In another example, a child might repeatedly tell their parents, “Wear your seatbelt,” every time they leave the house. They believe that if they don’t say it, something bad–like a car accident–could happen. Though the action (telling them to wear a seatbelt) and the thought (the fear of an accident) are not logically connected, the child feels an overwhelming need to per the action to prevent harm.

Magical thinking doesn’t just affect children. For adults, it might manifest in behaviors like tapping the light switch four times every time they go to turn the lights on or off. They might believe that this action will keep them safe from a fire or other dangers, even though there is no real connection between the thought and the compulsion. Sometimes, these rituals may seem perfectly logical in the mind of the person affected, even if they are irrational or have no actual impact on the feared outcome.

How emotional contamination impacts daily life

The impact of emotional contamination OCD can be severe. Compulsions range from subtle behaviors to extreme rituals. The intrusive thoughts and the anxiety they generate are profound, often leading individuals to avoid people, places, and even situations they once felt comfortable with.

One example that stands out is Jane*, a young adult in her twenties, whom I worked with. Jane’s OCD intensified after a traumatic event: her best friend and roommate was sexually assaulted during spring break. After the assault, she began to attach her fears to her friend’s clothing and began to see them as contaminated. 

At first, Jane was careful not to let her laundry touch her friend’s. However, this soon wasn’t enough. She believed that even using silverware or dishes her friend had used could lead her to become like the person who had assaulted her best friend. She knew this was illogical, but the anxiety was so great, and the sense of urgency so intense, that even the slightest possibility that it could be true led her to take extreme measures. 

The anxiety didn’t stop at avoiding her friend’s clothing or belongings. Even though she wanted to be supportive of her friend in her time of need, Jane began to avoid spending time with her altogether, even rearranging her schedule to limit contact. She was unaware of why this was happening, but she was full of guilt and shame, believing herself to be a terrible friend. 

By the time Jane entered treatment, she had begun making plans to move out. She had decided that her fear and the potential of harming someone else was too great of a risk and that it would be easier to isolate herself. Thankfully, she was able to start OCD treatment before she took that drastic step and began practicing exposure and response prevention (ERP) with me. 

Soon, Jane began to recognize that these were just thoughts and that she didn’t need to avoid her loved ones or perform compulsions to feel safe. She was able to be present with her friend again. Treatment helped her learn to manage the symptoms of OCD and enabled her to regain her life.

Find the right OCD therapist for you

All our therapists are licensed and trained in exposure and response prevention therapy (ERP), the gold standard treatment for OCD.

Treatment for emotional contamination OCD

Like Jane, you can conquer OCD with the right treatment. The most effective approach involves working with a licensed therapist who specializes in OCD and is trained in ERP.

ERP–a form of cognitive behavioral therapy (CBT)–is widely considered the gold-standard treatment for OCD. Studies have found that 80% of people who undergo ERP experience a significant reduction in their symptoms.

ERP is designed to help individuals face their fears without engaging in compulsive behaviors like avoidance. Through ERP, you will learn how to sit with uncomfortable feelings and resist the urge to act on your obsessions. You will see that anxiety, like any other feeling, eventually passes, and you don’t have to do anything to make this happen.

It’s essential to see a specialist for OCD treatment because they are trained to guide you in overcoming avoidance and other compulsions. These therapists teach you how to accept the uncertainty behind OCD fears and give you the tools and knowledge needed to learn how to manage OCD.
