Mental Compulsions: The Invisible OCD Symptoms

What Is a Mental Compulsion?

Well, a compulsion, in OCD, is anything done to reduce the anxiety, discomfort or doubt caused by an obsessive or intrusive thought. The goal of a compulsion is relief, but it is almost always only temporary relief. Most people are aware of what behavioral compulsions are (the checking, the cleaning, the counting) because these are often what is portrayed by media. But compulsions don't have to involve any physical action at all.

Mental compulsions are internal responses to obsessions or intrusive thoughts. They are just as time-consuming, just as exhausting, and just as good at keeping the OCD cycle going and therefore, someone stuck.

The tricky part is that mental compulsions often feel productive. They feel like thinking, like problem-solving, like being responsible, like processing, etc. That's part of what makes them so hard to identify and so hard to stop.

What Mental Compulsions Actually Look Like

Mental compulsions can look different depending on the person and the OCD presentation. Some of the most common ones include:

• Mental reviewing- going back over a conversation, an event, or a decision in your mind to check whether you said something wrong, did something harmful, or made the right choice.

• Reassuring yourself- telling yourself over and over that everything is fine, that you're a good person, that the feared thing didn't happen or won’t happen.

• Thought neutralizing- canceling out a bad thought with a good one, replacing a disturbing image with a comforting one, saying a phrase internally to undo the thought.

• Ruminating (or “figuring it out”)- trying to logically argue your way out of an obsessive or intrusive thought, examining the thought from every angle to figure out whether it means something, searching for evidence that you're not the thing the thought implies you might be.

• Mental checking or body checking- checking your feelings to see if they're real, checking whether you love your partner, checking whether you feel attracted to someone, checking whether you feel remorse for something.

• Praying or counting- Using prayer, counting, or specific phrases internally as a way to neutralize anxiety or prevent something bad from happening.

Why Mental Compulsions Are So Hard to Catch

There are a few reasons mental compulsions go unrecognized so often. The first is that they're invisible. There's no behavior to observe and nothing that looks noticeable from an outsider.

The second is that they feel justified. It can feel responsible to mental review, analyze or reason through your fears and thoughts, but this is just your compulsions disguised as problem-solving or processing.

The third is that even therapists can miss it and, particularly those without specific OCD training. When a client describes spending hours thinking about something, a therapist without OCD expertise might focus on the content of the thoughts rather than the function of the thinking.

If you've been in therapy before and felt like something was still being missed, this might be part of why.

So, what about “Pure O”

You may have heard the term Pure O, which is short for pure obsession OCD. It's commonly used to describe OCD that seems to involve only obsessions, with no compulsions. And while it's a (somewhat) useful term for the experience of OCD that doesn't look like the stereotypical presentation, it's a little misleading.Pure O almost always involves compulsions, but they’re just mental ones.

Why Identifying Mental Compulsions Matters for Treatment

This is one of the most important parts to understand about OCD and OCD treatment. When doing ERP treatment (Exposure and Response Prevention Therapy), which is the gold standard treatment for OCD, you have to gradually resist compulsions while engaging in things that trigger your obsessive/intrusive thoughts or things that you are avoiding. If the compulsions are mental and haven’t been identified, then ERP is only partly helpful.

Someone might do all the right behavioral work in treatment (stop checking the stove, stop seeking reassurance from their partner) but still be performing hours of mental compulsions that keep the cycle going. And this may cause progress to feel slower than it should.

Identifying mental compulsions and including them in treatment is a critical part of getting the full benefit of ERP. It's also one of the reasons working with a therapist who is specifically trained in OCD matters so much. Recognizing covert compulsions, naming them, and helping someone develop the capacity to resist them is such an important part of treatment.

What It Looks Like to Resist a Mental Compulsion

One of the most common questions I get asked is: how do I stop mental compulsions? If the compulsion is a thought, how do I not think it? And, to be honest it can be such a “heady” and confusing task.

The answer is not thought suppression (we know that trying to not think a thought makes it come back stronger). But, preventing a mental compulsion isn't about forcing the thought out of your mind, but rather noticing the urge to perform the compulsion and choosing not to follow through on it. It’s letting the obsession or intrusive thought be there (this is different than the mental compulsion), with the anxiety and discomfort that it brings, without picking up the mental thread and running with it or going down the rabbit hole (which is the compulsive part). It's a practice of sitting with uncertainty rather than immediately trying to figure out, fix or fight the thoughts and fears that it brings.

It's hard, but it's also one of the most important parts of OCD recovery.

You Don't Have to Keep Fighting This Alone

If you've been living inside your own head (reviewing, analyzing, reasoning, neutralizing) and you're exhausted, I want you to know that what you're experiencing is real, it has a name, and it is very treatable.

Frequently Asked Questions About Mental Compulsions

What are mental compulsions in OCD? Mental compulsions are internal, invisible responses to OCD obsessions & intrusive thoughts. They are things like mental reviewing, giving yourself reassurance, thought neutralizing, and analyzing intrusive thoughts. Like physical compulsions, they provide temporary relief from anxiety but maintain the OCD cycle over time.

How do I know if I have mental compulsions? If you spend significant time internally reviewing events, reasoning through intrusive thoughts, checking your feelings, or trying to neutralize anxiety with mental processes, those are likely mental compulsions. A key sign is that the relief is temporary and the anxiety returns, often stronger than before. As always, it’s important to get assessed by a therapist in order to truly know what you are struggling with.

Are mental compulsions the same as rumination? Rumination (which is the process of going over something again and again to find an answer to an unanswerable question) is one type of mental compulsion.

Can you have OCD with only mental compulsions? Yes. Many people with OCD have primarily or exclusively mental compulsions. The OCD cycle is the same— obsession, anxiety, compulsion, temporary relief— the compulsions are just mental rather than physical.

Why are mental compulsions so hard to stop? Because they feel productive. Analyzing something (a thought, a situation, a feeling, a sensation) feels like self-awareness. The compulsion disguises itself as something useful, which makes it much harder to recognize and resist.

How are mental compulsions treated? With ERP (Exposure and Response Prevention), the same approach used for behavioral compulsions. The goal is to learn to sit with the obsession or intrusive thought and the anxiety it produces without performing the mental compulsion. This is hard work and is most effective with a therapist specifically trained in OCD.

Does resisting mental compulsions mean suppressing thoughts? No and this is an important (and sometimes confusing) distinction. Thought suppression (trying to force a thought out of your mind) actually makes thoughts more persistent. Resisting a mental compulsion means noticing the urge to review, analyze, or neutralize and choosing not to follow through, while allowing the obsession and discomfort to be present.
