Obsessive-Compulsive Disorder (OCD) and Purely Obsessional OCD (Pure O)

Many people spend years believing they are simply perfectionists, overthinkers, or highly responsible individuals. In reality, persistent intrusive thoughts, compulsive behaviors, and relentless mental checking may indicate OCD rather than generalized anxiety.

Not all OCD symptoms are visible. Many individuals experience a form of OCD known as Pure O (Purely Obsessional OCD), where the primary compulsions happen internally rather than through observable behaviors.

OCD —PURE O THERAPIST IN PHILADELPHIA

Dr. Kelly Romirowsky, PsyD, specializes in the assessment and treatment of (OCD), including Pure O, and other obsessional presentations. Through comprehensive evaluation and evidence-based treatment, she helps individuals break free from cycles of intrusive thoughts, compulsions, and uncertainty while building lasting symptom relief.

OCD— PURELY OBSESSIONAL OCD

Obsessions are intrusive, unwanted thoughts, images, or urges that create anxiety or distress. Compulsions are behaviors or mental rituals performed to reduce that anxiety. While many people associate OCD with excessive handwashing or checking, compulsions are often much less obvious. Some individuals experience primarily mental compulsions that remain invisible to others.

—WHO I HELP

The Hidden Compulsion: Rumination

One of the most common compulsions in Pure O is rumination. Rumination involves repeatedly analyzing, reviewing, debating, or mentally solving intrusive thoughts in an attempt to feel better or gain certainty. Although it can feel productive, rumination keeps OCD active.

How OCD Impacts Daily Life

01

OCD affects far more than time management. Many individuals feel mentally occupied throughout the day, making it difficult to fully engage in work, relationships, parenting, or leisure activities. Even when symptoms are not visible, the mental effort required to manage obsessions and compulsions can be overwhelming.

02

For individuals with Pure O (Purely Obsessional OCD), this impact is often hidden. Hours may be spent mentally reviewing conversations, seeking certainty, analyzing intrusive thoughts, or attempting to resolve doubts that never feel fully settled. While these compulsions occur internally, they can be just as disruptive and exhausting as more visible OCD behaviors.

—WHAT I OFFER

Three doors into the same practice.

Evidence-based therapy, comprehensive psychological evaluations, and child psychoeducational testing — delivered with the same diagnostic rigor and clinical depth.

SERVICE 01

Assessment Approach

Comprehensive psychological evaluation identify the specific patterns maintaining symptoms and distinguish OCD from other anxiety-related conditions. Understanding the exact nature of the OCD cycle—including the role of obsessions, compulsions, rumination, and avoidance—allows treatment to target the factors keeping symptoms in place.

SERVICE 02

Evidence-Based Treatment

Exposure and Response Prevention (ERP) is considered the gold-standard treatment for OCD.

Many people enter treatment hoping to eliminate intrusive thoughts. ERP takes a different approach. Instead of trying to get rid of thoughts, treatment focuses on changing how you respond to them.

SERVICE 03

Treatment Goals

Reduce compulsive behaviors and mental rituals, Decrease the impact of intrusive thought, Improve daily functioning, Increase tolerance for uncertainty, Build confidence in managing anxiety

Recovery is not about eliminating every unwanted thought. It is about learning how to respond differently so OCD no longer controls your life.
