Do you experience thoughts, mental images, or urges that scare you, disgust you, or make you question yourself? Do you feel compelled to check, review, confess, research, or ask for reassurance—even when part of you knows it isn’t helping?
When patterns like these start interfering with your life, it may be worth getting evaluated for obsessive-compulsive disorder (OCD).
How can I get diagnosed with OCD?
To get diagnosed with OCD, you need to meet with a licensed mental health professional who will evaluate your symptoms, including any obsessions, compulsions, and the impact they have on your daily life.
There is no blood test, brain scan, or other medical test that can diagnose OCD, but clinicians often use structured interviews and questionnaires to support diagnosis, such as:
- Dimensional Obsessive-Compulsive Scale (DOCS): Assesses the severity of OCD symptoms
- Yale-Brown Obsessive Compulsive Scale (Y-BOCS): Measures symptom severity
- Structured Clinical Interview for DSM Disorders (SCID): Helps clinicians assess symptoms and rule out other conditions
What criteria are used to diagnose OCD?
Mental health professionals use criteria from the Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR) to diagnose OCD.
To receive a diagnosis, a person must experience obsessions, compulsions, or both, and those symptoms must be severe enough to cause significant distress or interfere with daily life. Clinicians also need to rule out other possible explanations, such as substance use, medical conditions, or other mental health disorders.
Who can diagnose OCD?
If you think you may have OCD, the best place to start is with a licensed mental health professional who is trained to assess and treat OCD. This includes:
- Psychiatrists (can diagnose and prescribe medication)
- Psychologists (can diagnose OCD and provide therapy)
- Licensed therapists and counselors (may diagnose and treat OCD, depending on state laws)
Primary care providers (PCPs) can help rule out medical causes of symptoms and provide referrals, but it is recommended to see a mental health specialist for a comprehensive OCD evaluation.
Can you self-diagnose OCD?
No. While online quizzes and symptom checkers can help you recognize possible signs of OCD, they can’t diagnose the condition.
Only a qualified mental health professional can determine whether you meet the criteria for OCD.
How long does an OCD diagnosis take?
An OCD diagnosis can sometimes be made during the first appointment, especially when symptoms clearly align with the condition. In other cases, a clinician may need one or two additional sessions to better understand a person’s experiences and rule out other conditions with overlapping symptoms, such as anxiety disorders, depression, or attention-deficit hyperactivity disorder (ADHD).
What can I expect after diagnosis?
After receiving an OCD diagnosis, the next step is getting appropriate care. The most effective treatment for OCD is exposure and response prevention (ERP) therapy, a specialized form of cognitive behavioral therapy (CBT) designed specifically for OCD.
ERP has two core elements:
- Exposure: Gradually facing thoughts, images, feelings, urges, sensations, or situations that trigger obsessions.
- Response prevention: Resisting the compulsive behaviors that usually follow.
Over time, ERP helps people build confidence in their ability to handle fear, uncertainty, and discomfort without letting anxiety dictate their choices.
Studies show that ERP therapy is highly effective, with 80% of people with OCD experiencing a significant reduction in their symptoms.
Depending on a person’s needs, clinicians may also recommend medication, acceptance and commitment therapy (ACT), mindfulness-based strategies, or more intensive levels of care.

Bottom line
If you think you may have OCD, seeking an evaluation is an important first step. A diagnosis won’t answer every question overnight, but it can provide clarity about what you’re experiencing and help you access treatments that have helped many people manage OCD and reclaim their lives.
