The first step in the treatment of OCD is conducting a thorough assessment. Your child’s clinician will ask them questions about the intrusive thoughts they experience and the behaviors they use to try to get rid of them. Here are a few examples of types of OCD we commonly treat:
What it is: This type involves a strong fear of getting sick, dirty, or “contaminated” by germs, chemicals, or even certain people or environments that feel “unclean.”
Obsessions (the thoughts): “What if I catch a deadly disease?” or “That surface is dirty—what if I spread germs to my family?”
Compulsions (the behaviors): Repeatedly washing hands, showering, changing clothes, avoiding public spaces, or refusing to touch certain things or people.
How it feels: The anxiety doesn’t go away until the person has cleaned or avoided the “contaminated” thing—but even then, the relief might be short-lived.

What it is: This type is driven by fear that something terrible will happen because of a mistake or oversight.
Obsessions: “What if I left the stove on and the house burns down?” or “What if I didn’t lock the door and someone breaks in?”
Compulsions: Checking appliances, locks, lights, or emails/texts over and over. Some people may ask for repeated reassurance from others too.
How it feels: The person may know they already checked, but doubt creeps in, making them feel like they have to check “just one more time” to be sure.

What it is: People with this type feel intense discomfort when things aren’t arranged in a certain way or don’t feel “even” or “balanced.”
Obsessions: “That picture is crooked—it’s driving me crazy,” or “I need to tap both sides of the table equally or something bad might happen.”
Compulsions: Arranging, reordering, or repeating actions until things feel “right.” This can include touching, tapping, counting, or doing things in a specific sequence.
How it feels: The goal isn’t always to prevent something bad from happening—it’s often about calming a powerful sense of internal discomfort.
What it is: This involves unwanted, upsetting thoughts that go against a person’s values or character. These thoughts are not something the person wants to act on—they’re distressing and feel wrong.
Obsessions: “What if I accidentally hurt my baby?” “What if I shouted something offensive in public?” or “Am I a bad person for having that thought?”
Compulsions: Avoiding certain situations, mentally reviewing past actions, seeking reassurance, or trying to “cancel out” the thought with a different one.
How it feels: These thoughts are scary and confusing, often leaving the person feeling ashamed or worried that they might be dangerous—even though they aren’t.

Exposure and Response Prevention (ERP) is a type of cognitive-behavioral therapy that helps people face their fears (exposure) without doing the usual rituals or behaviors to feel better (response prevention). Over time, this helps the brain learn that the feared outcome doesn’t happen—or that it can be tolerated without the compulsion.
ERP begins with easier exposures from the bottom of the hierarchy. The person intentionally faces a trigger (exposure) without doing the compulsion (response prevention).
Example: Touching a doorknob and resisting the urge to wash hands.
At first, anxiety will go up—but with time, it naturally comes down. This teaches the brain: "I can handle this without doing the ritual."
Exposure is practiced again and again, until the trigger no longer causes overwhelming anxiety. Then the person moves up to more challenging exposures. The key is not doing the compulsion, even when it feels uncomfortable. Over time, the brain learns that the feared consequences don’t happen—or don’t need to be feared. Each success builds confidence and weakens OCD’s grip. One of the deeper goals of ERP is helping the person accept uncertainty instead of trying to feel 100% safe or “just right.” This is powerful, because OCD thrives on the promise of certainty.
Once progress is made, it’s important to keep practicing exposures and using the tools learned in therapy. OCD can sneak back in, especially during stress, so regular practice helps keep it in check.
