Quick Answer
An OCD diagnostic interview explores your obsessions, compulsions, including mental rituals, avoidance, how much time they take and how much distress they cause. The clinician also asks about insight, tics, other conditions and family history, and rules out look-alikes like anxiety, depression, autism and body-focused repetitive behaviors.
Understanding OCD Diagnostic Interview
There’s no blood test or scan for OCD. Diagnosis comes from a careful interview. The clinician asks about obsessions, which are unwanted, intrusive thoughts, images or urges that cause distress, and compulsions, which are behaviors or mental acts done to reduce that distress or prevent something bad. Compulsions include visible rituals like washing and checking, and invisible ones like reviewing memories, counting, praying to cancel a thought or seeking reassurance. Avoidance is also explored, since steering around triggers can hide how much OCD is shaping life. This guide is part of Dr. Farkas's New York OCD resources.
The International OCD Foundation explains that for a diagnosis, the cycle of obsessions and compulsions is typically so intense that it consumes a lot of time, such as more than an hour a day, causes intense distress or gets in the way of important activities. It also notes that most people have unwanted intrusive thoughts at times, and what sets OCD apart is how frequent and distressing they become. The interview helps draw that line carefully. Our guide on Y-BOCS scoring explains how severity is measured once OCD is identified.
For New Yorkers who’ve lived with unexplained rituals or frightening thoughts for years, a careful interview can finally put a name to it. The NYC Health Department found that about 945,000 adult New Yorkers, or 14%, had an unmet need for mental health treatment in the past year. Secure video visits from anywhere in New York can make it easier to start OCD care without adding travel to an already crowded day.
Questions about obsessions and rituals, insight and tics, and ruling out look-alike conditions are the three parts of the interview this guide covers.
Ruling out look-alikes
Several conditions can look like OCD. Generalized anxiety involves worry about real-life concerns rather than intrusive thoughts with rituals. Depression can bring guilty rumination. Autism can involve routines and repetitive behaviors that feel comforting rather than distressing. Obsessive-compulsive personality traits involve perfectionism that feels right to the person. Psychotic disorders involve fixed beliefs without the same doubt. Sorting these out takes careful questions and sometimes more than one visit.
Talking about taboo thoughts
OCD often targets what people care about most, producing thoughts about harm, sex, religion or morality that feel horrifying. Many people fear that saying these thoughts aloud will lead to being judged or reported. Clinicians who treat OCD know these thoughts are common in OCD and go against what the person values. You can share at your own pace. Naming the thoughts often brings relief and allows accurate diagnosis and treatment.

Insight
Many people with OCD recognize their fears are unlikely or excessive, yet feel unable to stop. Others are less sure, and some feel strongly that their fears are realistic. Clinicians describe insight as good or fair, poor, or absent. Insight affects how treatment is explained and paced, but it doesn’t rule out OCD or treatment. Our guide on OCD with poor insight covers this in more detail. The interview asks gently about how you see your fears.
Tics and related conditions
The clinician asks about current or past tics, which are sudden repeated movements or sounds, since tic-related OCD can respond differently to treatment. Questions also cover body-focused repetitive behaviors like skin picking and hair pulling, body dysmorphic concerns, hoarding and eating concerns. These related conditions often occur alongside OCD. Family history of OCD, tics or anxiety is noted too. Each of these details helps build an accurate picture and a fitting plan. Our guides on preparing for an OCD evaluation and OCD with poor insight cover related topics.
OCD diagnosis for New York patients
OCD diagnostic interviews work well by secure video from a private space. Visits run by secure video anywhere in New York, while you’re physically in the state. The practice is in-network with Aetna and Cigna; confirm your New York plan with the office, and see self-pay fees on the Good Faith Estimate page.
After the interview
At the end, the clinician shares their impressions, including whether OCD is present, how severe it seems and what else may be contributing. You’ll discuss treatment options, usually exposure and response prevention, medication or both. Questions are welcome. If more information is needed, a follow-up visit may be scheduled. Leaving with a clear understanding is the goal.
When to seek an evaluation
Seek an evaluation if intrusive thoughts and rituals take more than an hour a day, cause strong distress or interfere with work, relationships or sleep. Avoiding many situations because of fears is another sign. If thoughts include self-harm, call or text 988 right away. OCD is treatable, and an accurate diagnosis is the first step.
