Pure O OCD Seattle: When Intrusive Thoughts Won’t Stop
You don’t wash your hands constantly or check locks repeatedly—but intrusive, disturbing thoughts consume your mind. Welcome to Pure O OCD, the “invisible” form of OCD that torments in silence.
You’re a loving parent, but violent images of harming your child flash through your mind. You’re happily married, but intrusive sexual thoughts make you question everything. You’re deeply religious, but blasphemous thoughts plague you constantly.
These thoughts horrify you. They feel completely foreign to who you are. You spend hours mentally analyzing them, seeking reassurance, trying to prove they don’t mean anything. But the more you fight, the stronger they become.
You look completely normal on the outside—no visible rituals, no hand-washing, no checking. But inside, you’re trapped in a mental prison of relentless, disturbing thoughts.
This is Pure O OCD (Purely Obsessional OCD)—and you’re not alone. At Seattle Wellness Center, we specialize in treating this often-misunderstood form of OCD using evidence-based therapy that actually works.
Pure O OCD Seattle: What Is Purely Obsessional OCD?
Pure O OCD (Purely Obsessional OCD) is a form of obsessive-compulsive disorder where compulsions happen entirely inside your mind rather than through visible behaviors. While people with traditional OCD might wash their hands repeatedly or check locks multiple times, people with Pure O engage in hidden mental rituals.
🔬 Research Insight
In a study of 225 patients with OCD, 12.9% reported mental compulsions as their primary compulsion type. Research shows that what appears to be “purely obsessional” OCD actually involves hidden mental rituals—the compulsions are just invisible to others. Pure O is not “obsession-only”; mental compulsions are very much present.

The “Pure O” Name Is Misleading
The term “Pure O” suggests people only experience obsessions without compulsions—but this is a myth. People with Pure O absolutely have compulsions; they’re just mental rather than behavioral.
These hidden compulsions include:
- Mental reviewing – Replaying events to check if you did something wrong
- Mental reassurance – Constantly telling yourself “I would never do that”
- Mental counting or praying – Repeating phrases or numbers to neutralize thoughts
- Analyzing and ruminating – Spending hours trying to figure out what thoughts “mean”
- Checking feelings – Scanning your body for arousal or emotional responses
- Thought suppression – Trying desperately to push thoughts away
Because these compulsions are invisible, Pure O often goes undiagnosed for years—sometimes decades.
Why Pure O Is Often Misdiagnosed
Many people with Pure O are initially misdiagnosed with generalized anxiety disorder (GAD), depression, or even psychosis. Without visible compulsions, even experienced therapists can miss Pure O—especially if they’re not OCD specialists. This leads to years of ineffective treatment and unnecessary suffering.
Common Pure O OCD Themes: The Thoughts That Terrify
Pure O obsessions typically center around taboo, disturbing themes that feel completely contrary to your values. Here are the most common:
Harm OCD
Unwanted, graphic thoughts or images about hurting loved ones or strangers. A loving mother might have intrusive images of dropping her baby or violent thoughts about her child. A kind person might imagine pushing someone in front of a train.
The terror: “What if these thoughts mean I’m secretly dangerous? What if I lose control and actually do it?”
Mental compulsions: Constantly reassuring yourself you’d never hurt anyone, avoiding being alone with loved ones, mentally reviewing past interactions for “evidence” you’re safe.
Sexual Orientation OCD (SO-OCD)
Persistent, intrusive doubts about your sexual orientation that contradict your actual attractions. A straight person might obsess: “What if I’m secretly gay and don’t know it?” A gay person might fear they’re actually straight.
The terror: “What if everything I thought I knew about myself is wrong?”
Mental compulsions: Scanning your body for arousal around certain people, mentally reviewing past relationships, constantly testing your attractions, seeking reassurance online.
Pedophilia OCD (POCD)
Horrifying intrusive thoughts about inappropriate attraction to children. This is particularly devastating for parents, teachers, or anyone who works with children.
The terror: “What if these thoughts mean I’m a pedophile? What if I’m dangerous to children?”
Mental compulsions: Avoiding children entirely, constantly checking for inappropriate arousal, mentally reviewing all interactions with children, seeking reassurance you’re not a predator.
Religious/Scrupulosity OCD
Blasphemous thoughts, fear of offending God, or intrusive images of sacrilege. Deeply religious people might have thoughts like “F*** God” or disturbing sexual images involving religious figures.
The terror: “What if I’ve committed an unforgivable sin? What if God condemns me for these thoughts?”
Mental compulsions: Repetitive mental prayers, confessing thoughts to clergy, mentally asking for forgiveness hundreds of times, analyzing whether thoughts are “sinful.”
Relationship OCD (ROCD)
Obsessive doubts about whether you love your partner, whether they’re “the one,” or whether you should be in the relationship. These thoughts persist even in happy, healthy relationships.
The terror: “What if I don’t actually love them? What if I’m with the wrong person?”
Mental compulsions: Constantly analyzing your feelings, comparing your relationship to others’, mentally listing your partner’s flaws and positive qualities, seeking reassurance from friends.
Existential/Philosophical OCD
Obsessive thoughts about the nature of reality, consciousness, death, or existence. Questions like “What if nothing is real?” or “What happens after death?” become all-consuming ruminations.
The terror: “What if I figure out something terrible about existence? What if reality isn’t what I think?”
Mental compulsions: Hours of philosophical rumination, seeking certainty about unanswerable questions, mentally testing whether reality “feels real.”
⚠️ Critical Truth About Pure O Thoughts
These intrusive thoughts are EGO-DYSTONIC—meaning they go directly against your values and who you are. The fact that they horrify you is actually evidence they DON’T reflect your true desires. People who actually want to harm others don’t have OCD about it—they just do it.
Pure O OCD Seattle: How to Recognize the Symptoms
Pure O can be difficult to identify because there are no visible behaviors. Here are the telltale signs:
Primary Symptoms
- Intrusive, disturbing thoughts that feel completely foreign to your character and values
- Intense anxiety or disgust in response to these thoughts
- Mental rituals performed repeatedly to reduce anxiety or “neutralize” thoughts
- Excessive time spent analyzing, ruminating, or seeking reassurance (often hours per day)
- Avoidance behaviors to prevent triggering intrusive thoughts
- Shame and secrecy about your thoughts, fearing others will judge you
How Pure O Differs from Normal Intrusive Thoughts
Everyone has intrusive thoughts. Research shows 90% of people experience unwanted thoughts. The difference with Pure O is:
✓ Normal Intrusive Thoughts
- Fleeting, passing quickly
- Dismissed easily
- Don’t cause significant distress
- No compulsive response needed
- Don’t interfere with daily life
⚠️ Pure O OCD Thoughts
- Persistent, recurring constantly
- Feel impossible to dismiss
- Cause extreme anxiety/distress
- Trigger hours of mental rituals
- Significantly impair functioning
🔬 Research Insight
Studies show that Exposure and Response Prevention (ERP) therapy—the gold standard treatment for OCD—achieves an 80% success rate in significantly reducing Pure O symptoms. This makes Pure O one of the most treatable mental health conditions when properly diagnosed and treated with specialized therapy.

Evidence-Based Treatment for Pure O OCD in Seattle
The good news: Pure O OCD is highly treatable. With the right therapy, most people achieve significant relief and learn to live without the constant mental torment.
Exposure and Response Prevention (ERP) – The Gold Standard
ERP therapy is the most effective treatment for Pure O OCD. Unlike regular talk therapy (which can actually make Pure O worse by encouraging rumination), ERP works by:
- Exposure – Gradually, intentionally exposing yourself to the intrusive thoughts without avoiding them
- Response Prevention – Resisting the urge to perform mental compulsions (no reassurance-seeking, no mental reviewing, no analyzing)
- Habituation – Over time, your anxiety decreases naturally as your brain learns the thoughts aren’t dangerous
How ERP works in practice: Your therapist helps you face feared thoughts while blocking compulsions. For example, someone with harm OCD might practice having the intrusive thought without seeking reassurance or mentally reviewing evidence they’re safe. This breaks the OCD cycle.
Acceptance and Commitment Therapy (ACT)
Often combined with ERP, ACT helps you:
- Accept uncertainty rather than seeking impossible certainty
- Recognize thoughts as mental events, not facts or predictions
- Live according to your values despite uncomfortable thoughts
- Develop psychological flexibility with distressing mental content
Medication
SSRIs (Selective Serotonin Reuptake Inhibitors) are often prescribed alongside therapy, especially for moderate to severe Pure O. Common medications include:
- Fluoxetine (Prozac)
- Sertraline (Zoloft)
- Fluvoxamine (Luvox)
- Paroxetine (Paxil)
Important: Medication works best when combined with ERP therapy. Pills alone don’t teach you how to respond differently to intrusive thoughts.
What NOT to Do (Common Treatment Mistakes)
Some therapeutic approaches can actually worsen Pure O:
- ❌ Traditional talk therapy that encourages analyzing the thoughts
- ❌ Reassurance from therapists (“You would never do that”)
- ❌ Thought stopping techniques that try to eliminate thoughts
- ❌ Mindfulness used as avoidance (using meditation to escape thoughts)
This is why seeing an OCD specialist is crucial. General therapists, even skilled ones, may not recognize Pure O or may use approaches that reinforce compulsions.

Frequently Asked Questions About Pure O OCD
Click each question to see the answer:
Do my intrusive thoughts mean I’m a bad person?
Absolutely not. The fact that these thoughts horrify and disgust you is proof they don’t reflect your character. People with Pure O have intrusive thoughts precisely BECAUSE those thoughts go against their values. Someone who actually wanted to harm people wouldn’t have OCD about it—they’d just do it without distress.
Will these thoughts ever go away completely?
The goal isn’t to eliminate intrusive thoughts (everyone has them). The goal is to change your relationship with them so they no longer cause distress or control your life. With successful ERP therapy, most people find the thoughts become much less frequent and when they do occur, they’re no longer scary—just mental noise you can dismiss easily.
Can Pure O OCD be cured?
While OCD is a chronic condition, many people achieve full remission with proper treatment. With ERP therapy and sometimes medication, you can reach a point where OCD no longer significantly impacts your life. Some people need occasional “tune-up” sessions during stressful periods, but lasting recovery is absolutely possible.
How long does Pure O treatment take?
Most people see significant improvement within 12-16 weeks of intensive ERP therapy. However, the timeline varies based on symptom severity and how long you’ve had Pure O. Some people benefit from longer-term treatment to address multiple themes or deeply ingrained patterns.
Should I tell my therapist about my disturbing thoughts?
YES. An OCD specialist has heard it all and will not judge you. They understand these are intrusive thoughts, not desires. Being completely honest about your thoughts—no matter how disturbing—is essential for effective treatment. The thoughts you’re most ashamed of are often the most important to address in therapy.
What if I’ve had Pure O for years—is it too late?
It’s never too late. Many people don’t get properly diagnosed until they’ve suffered for 10, 20, or even 30+ years. ERP therapy is effective regardless of how long you’ve had Pure O. While ingrained patterns may take longer to change, the fundamental treatment process works the same way.
