Working with OCD in Therapy: What to Say and What to Avoid
OCD is not anxious perfectionism. It is not being very organized or liking things a certain way. It is not the checking that most people do when they cannot remember if they locked the door.
OCD is a disorder in which intrusive, unwanted thoughts (obsessions) produce intense distress, and the person engages in behaviors or mental acts (compulsions) to reduce that distress — temporarily, and at significant cost. The relief from compulsions is real but short-lived, and the cycle reinforces itself. Over time, the obsessions become more frequent, the distress more intense, and the compulsions more elaborate.
The most important clinical fact about OCD for general outpatient therapists is this: standard approaches to anxiety — exploring the thought content, seeking reassurance, engaging with the “what if,” doing thought records, helping the client examine whether the feared outcome is realistic — make OCD worse. Not neutral. Worse.
Why standard CBT does not work for OCD
In most anxiety presentations, examining the thought content and testing its accuracy is helpful. The client worries they will fail a presentation; you explore the evidence, find it is overstated, and the anxiety reduces.
In OCD, engaging with the content of the obsession is a form of reassurance-seeking. The brain learns: this thought requires a response. The more the therapist and client analyze the obsession — “do you really think you would do that?” “let’s look at the evidence that you’re a bad person” — the more the brain treats it as a real threat requiring management. The OCD strengthens.
The evidence-based treatment is Exposure and Response Prevention (ERP): deliberately triggering the obsessive thought and then resisting the compulsive response, allowing the anxiety to rise and fall without neutralizing it. This requires specialist training and is not something to attempt without it.
What general outpatient therapists can do
If you are not trained in ERP and you have a client with OCD, the most useful things you can do are:
First, recognize it. OCD is frequently misdiagnosed as generalized anxiety, depression, or trauma. The presence of obsessions and compulsions — even if the compulsions are mental rather than behavioral — is the diagnostic signal.
Second, stop reassurance-giving. Reassurance is a compulsion that the therapist is performing. When a client asks “do you think I would ever do that?” — the OCD-informed answer is not reassurance. It is:
“I notice I want to reassure you, and I’ve learned that the reassurance actually feeds the OCD rather than helping it. What if we didn’t answer that question right now and saw what happened?”
Third, refer to ERP-trained treatment. OCD responds dramatically to ERP in a way it does not respond to other approaches. Connecting the client with specialist treatment is the most useful clinical act for moderate to severe presentations.
The question therapists dread
Clients with harm OCD — obsessions about harming themselves or others — frequently ask their therapists some version of: “Do you think I would actually do it?”
The clinical answer is careful. People with harm OCD are not at elevated risk of acting on their thoughts. The horror the thoughts produce is itself evidence that the person does not want to do what they are imagining. But giving reassurance to this specific question feeds the cycle.
“I understand why you’re asking me that. I’m also aware that answering it directly is part of what OCD does — it keeps you seeking certainty in a situation where certainty isn’t available. What if we talked about what it’s like to live with that question rather than trying to answer it?”
