Obsessive-Compulsive Disorder (OCD)
OCD is a condition where the mind can become caught in a loop of intrusive thoughts (obsessions), often experienced as persistent fears or questions that feel impossible to ignore, followed by attempts to gain certainty or relief from them (compulsions).
At its core, OCD is a disorder of doubt. It is driven by a deep intolerance of uncertainty that can leave people stuck in the pursuit of answers to questions that don’t actually have one.
In an effort to resolve that doubt and find certainty, people with OCD turn to a variety of responses known as compulsions. These can include behaviors that are visible to others, as well as things that happen internally in the mind. Common examples include checking, reassurance seeking, avoidance, researching, mentally reviewing situations, or trying to “figure out” the thought.
Because compulsions are driven by specific fears, OCD can attach itself to many different themes, known clinically as subtypes. Although the fears may vary from person to person, the underlying cycle of doubt, anxiety, and attempts to gain certainty remains the same.
Common Forms of OCD We Treat
OCD can attack almost anything that matters to a person. It is common to experience more than one theme, and the focus of the fears can shift over time. As someone begins to face one set of fears, OCD may try to latch onto something new in an effort to keep the doubt going.
The subtypes below are grouped into four categories to help illustrate the different ways OCD can show up.
Germ & Illness Fears
Contamination OCD
The type most people think of when they hear “OCD,” because it’s the one most often portrayed in movies and media. It involves intense fears about germs, illness, or contamination, often leading to repeated washing, cleaning, or avoiding objects and places that feel “dirty” or unsafe.
Health OCD
Persistent worries about having or developing a serious illness, even after reassurance or medical tests. Many people find themselves repeatedly checking symptoms, researching online, or asking for reassurance from doctors or loved ones.
Personal Responsibility & Preventing Harm
Checking OCD
Recurrent fears about causing harm through mistakes or negligence. Individuals may feel compelled to repeatedly check things like locks, appliances, messages, or tasks to make sure nothing bad will happen, often accompanied by the feeling that something important may have been missed.
Redoing/Just-Right OCD
A persistent feeling that something is not quite right or incomplete. Individuals may feel compelled to redo actions, repeat movements, rewrite things, or adjust objects until they feel “just right,” often repeating things a certain number of times or until the action feels complete to prevent a specific fear from happening.
Magical Thinking OCD
A belief that certain thoughts, words, or actions could influence future outcomes. People may feel responsible for preventing something bad from happening and perform rituals or avoid certain behaviors to keep others safe– similar to the idea of “step on a crack, break your mother’s back.”
False Memory OCD
A fear of having done something harmful but not remembering it. People may repeatedly replay events in their mind or seek reassurance, trying to determine whether something bad happened– asking questions like, “What if I hit someone with my car and I don’t remember it?”
Moral Scrupulosity OCD
Overwhelming concern about being a bad person, leading individuals to repeatedly seek reassurance, mentally review situations, or analyze their intentions. They may question whether they are truly a good person or just pretending to be.
For some people, these fears center around religious beliefs— known as religious scrupulosity— such as worrying about offending God or not being faithful enough. These fears can lead to repetitive behaviors like confession, excessive prayer, or cleansing rituals meant to remove a sense of spiritual guilt or impurity.
Relationship & Identity Doubt
Relationship OCD (ROCD)
OCD that targets romantic relationships. It often shows up as persistent doubts about one’s feelings toward a partner— What if I don’t really love them? People may find themselves repeatedly seeking reassurance, checking for signs of attraction, or trying to make sure their feelings about the relationship feel “right.”
Meta OCD
OCD that turns inward, causing people to question whether they actually have OCD– often involving fears of being dishonest or faking it.
Sexual Orientation OCD (SO-OCD)
Intrusive doubts about one’s sexual orientation that lead to repeatedly questioning feelings of attraction, analyzing past experiences, or checking reactions to others.
Trans OCD (TOCD)
Distressing doubts about whether one’s gender identity is “correct”, often leading people to worry that they might be in denial about who they truly are. Individuals may find themselves analyzing personality traits, interests, or past experiences to determine whether they mean something about their gender identity.
Intrusive Harm, Sexual, & Private Thoughts:
While these themes can feel alarming, they are a common way OCD shows up because it tends to target the things that matter most to us. They can feel especially disturbing because thoughts go directly against a person’s values or sense of who they are, something we call ego-dystonic thoughts. The very fact that the thoughts cause so much fear and discomfort is usually a sign that they do not reflect the person’s true intentions or desires.
Harm OCD
Intrusive thoughts and sometimes violent images about harming yourself or someone else that the person has no desire or intention of acting on. The distress comes from uncertainty about what the thoughts might mean and the fear that having them could mean losing control or acting on them.
People may cope by avoiding knives or other potential weapons, avoiding situations where the thoughts tend to show up, or avoiding being alone with themselves or others.
Pedophilic OCD (POCD)
Intrusive thoughts and sometimes images about being sexually attracted to children that feel deeply disturbing and completely inconsistent with the person’s values. The distress often centers around questioning what the thoughts might mean, worrying they could secretly be a bad or dangerous person, or fearing they would be judged as disgusting or immoral if others knew what they were thinking.
People often experience intense shame, may interpret normal body sensations as evidence of attraction, and feel compelled to closely monitor their bodies for signs of arousal. They may also avoid images of children, stay away from places like parks, schools, or playgrounds, distance themselves from children in their lives, or avoid certain words or topics that trigger the fear.
Sexual OCD
Intrusive sexual thoughts or images that appear suddenly and often show up in situations where they feel especially inappropriate, such as in professional settings, public spaces, or around people the individual would never want to think about in a sexual way.
The distress often comes from feeling embarrassed or ashamed that the thoughts are happening at all. People may worry about how they would be judged if others knew what they were thinking.
Mind-Reading OCD (thought broadcasting)
Intrusive fears that others can somehow hear, see, or know what you’re thinking. While the fear often centers around thoughts that feel disturbing or embarrassing, it can also involve ordinary thoughts the person feels should remain private, such as personal insecurities or secrets.
People may worry their thoughts are being exposed or “broadcast” to others and judged. This can lead to closely monitoring or trying to control their thoughts, and sometimes engaging in behaviors meant to prevent others from finding out what they are thinking.
