Your Therapist Isn't Going to Let You Off the Hook when it comes to OCD
What is ERP?
If you've ever Googled "OCD treatment," you've probably seen the acronym ERP. Exposure and Response Prevention is the gold-standard, evidence-based treatment for OCD — and it works. But it also asks something of you that feels genuinely counterintuitive: stay with the discomfort instead of escaping it.
What ERP Actually Is
OCD runs on a loop. An intrusive thought or situation triggers anxiety (the obsession), and the brain sends an urgent message: do something to make this stop. The "something" — the compulsion — works in the short term. Anxiety drops. Relief floods in.
The problem is that every time you respond to the obsession with a compulsion, you're teaching your brain that the only way to survive the distress is to escape it. The loop tightens. The threshold for triggering it lowers. Over time, OCD expands its territory.
ERP interrupts that cycle. In ERP, you deliberately encounter the feared trigger (the exposure) and then resist performing the compulsion (the response prevention). You sit with the anxiety — not to punish yourself, but to give your nervous system the evidence it's been denied: I can tolerate this. The worst doesn't happen. The feeling passes.
The goal is to stay present, not necessarily calm.
ERP differs from what most people expect from therapy. The goal is not to soothe your anxiety in the moment. It's not to breathe through it, reframe it, or make it smaller. In fact, trying to nullify distress during an ERP exercise can undermine the work.
The therapeutic target is the peak of distress — the moment when it feels most unbearable. That peak is where the learning happens. When a person experiences the height of their distress and discovers they can tolerate it without performing a compulsion, the brain begins to update its threat model. Anxiety that once felt unsurvivable becomes survivable. And then, over repeated exposures, it becomes less intense.
This is called inhibitory learning — your brain doesn't erase the old fear association, but it builds a new, stronger one: this is tolerable. It’s not meant to be cruel, it is meant to be the point.
The SUDS Scale
To do ERP effectively, your therapist needs to understand your experience from the inside. That's where the Subjective Units of Distress Scale (SUDS) comes in.
SUDS is a personal, 0–100 measure of distress intensity. Zero means no distress at all — you're relaxed, at baseline. One hundred is the most distress you can imagine experiencing. Everything in between maps to your own internal landscape.
"Subjective" is the key word. This scale isn't comparative — it doesn't matter how your 70 compares to someone else's 70. What matters is that it's calibrated to you, so you and your therapist can communicate clearly about where you are during an exposure and track changes over time.
SUDS serves a few important functions in ERP:
Building an exposure hierarchy. Before beginning exposures, your therapist will work with you to rank feared situations or triggers from lowest to highest SUDS. Treatment typically starts at the lower end and works up — not because the low-SUDS exposures are unimportant, but because repeated practice at manageable levels builds tolerance and confidence.
Monitoring distress during exposure. Your therapist may ask you to rate your SUDS periodically during an exercise. The goal is to observe how distress rises, peaks, and — over time, with practice — begins to come down on its own.
Tracking progress. A situation that once triggered an 85 might register at a 50 after several exposures. That shift is data. It tells you and your therapist that the work is doing what it's supposed to do.
How to Build Your Personal SUDS Scale
A SUDS scale is only useful if it's anchored to your actual experience — not a generic number line. Here's how to make it yours:
Anchor your 0 and your 100.
Think of a specific moment when you felt completely at ease — no tension, no worry, genuinely calm. That's your 0. Now think of the most distress you've ever experienced, or can imagine experiencing. That's your 100. You don't have to visit that memory in detail; just note that it exists at the top of your scale.
Place a few landmarks.
Think of real memories or situations that represent different levels of distress for you. A mild annoyance might be a 15. A frustrating conversation, a 35. A panic attack, an 80. Try to find anchors at roughly 25, 50, and 75. These don't have to be OCD-related — everyday experiences work well.
Write them down.
A SUDS scale you can reference is more useful than one you try to reconstruct in the middle of an exposure. Keep a simple written version — a number, a brief description, a memory — somewhere accessible.
Share it with your therapist.
Your SUDS scale becomes a communication tool. The more specific and personal it is, the more clearly your therapist can understand your experience during exposures and adjust accordingly.
ERP and Perinatal OCD: A Note for the Pregnancy and Postpartum Years
OCD can emerge for the first time — or intensify significantly — during pregnancy and the postpartum period. Perinatal OCD often looks different from the contamination or symmetry-based presentations most people picture when they think of OCD. The intrusive thoughts are frequently harm-focused, centered on the baby, and deeply distressing precisely because they feel so out of character. The compulsions — checking, avoiding, seeking reassurance — can be easy to mistake for cautious, loving parenting.
ERP is effective for perinatal OCD, and the core mechanism is the same: building tolerance at the peak of distress rather than escaping it. The exposure hierarchy simply looks different. A new parent might work with their therapist on gradually tolerating proximity to situations that trigger intrusive thoughts, resisting reassurance-seeking after a frightening image, or sitting with uncertainty about their baby's safety without checking.
It's worth naming that ERP during the perinatal period requires a therapist who understands both the treatment and the context. Perinatal OCD is frequently misidentified — as postpartum depression, as parenting anxiety, or sometimes (harmfully) as genuine danger. A clinician who knows the difference can help you move through ERP in a way that's calibrated to this specific season of life.
If you're in the pregnancy or postpartum period and recognizing yourself in any of this, you're not alone — and what you're experiencing is treatable. Reach out to Roots & Branches Wellness to connect with a therapist who specializes in perinatal mental health and ERP.
