The symptoms of obsessive compulsive disorder (OCD) include recurring unwanted thoughts, urges, or images and repetitive behaviors or mental acts that can cause distress or interfere with daily life. OCD can look different from one person to another, so recognizing the pattern is more useful than focusing on one isolated thought or behavior.
OCD is a mental health disorder marked by obsessions, compulsions, or both. Obsessions are intrusive and unwanted thoughts, urges, or mental images, while compulsions are repetitive behaviors or mental acts a person feels driven to perform, often to reduce distress caused by an obsession.
What are the main symptoms of obsessive compulsive disorder?
The main symptoms of OCD are obsessions, compulsions, or a combination of both. These symptoms can become difficult to control, consume significant time, cause distress, or interfere with work, relationships, school, and everyday responsibilities.
What are common OCD obsession symptoms?
Obsessions are recurring thoughts, urges, or mental images that are unwanted and often cause anxiety, fear, disgust, doubt, or another uncomfortable response. Common examples include:
- Fear of germs, contamination, or illness
- Repeated fears about harming yourself or another person
- Persistent doubts about whether something was done correctly
- Fear of losing control over your behavior
- Unwanted thoughts involving sex, religion, or harm
- Concern about losing or misplacing something important
- A strong need for symmetry, order, or things feeling exactly right
Having an unwanted thought does not automatically mean someone has OCD. NIMH notes that OCD involves a broader pattern in which symptoms are difficult to control and can cause significant distress or interfere with daily functioning.
The content of an intrusive thought can also be especially upsetting because it may conflict with a person’s values or intentions. An unwanted thought is not the same as an intention to act on that thought.
What are common OCD compulsion symptoms?
Compulsions are repetitive behaviors or mental acts that a person feels driven to perform, often in response to an obsession. Common examples include:
- Repeated handwashing or cleaning
- Checking locks, appliances, or other things repeatedly
- Counting objects or actions
- Arranging items in a particular order
- Repeating words or phrases silently
- Mentally reviewing an event to make sure nothing went wrong
- Repeatedly seeking reassurance about a feared possibility
Compulsions can be visible, such as washing or checking, but they can also happen entirely in the mind. Mental rituals may involve repeating phrases, reviewing memories, counting, or trying to cancel out an unwanted thought.
How is OCD different from normal worry or everyday habits?
OCD is different from ordinary worry, occasional checking, or personal preferences because the symptoms are typically difficult to control and can become distressing, time-consuming, or disruptive. NIMH reports that people with OCD may spend more than an hour a day dealing with obsessions or compulsions, although time alone does not determine whether someone has OCD.
For example, checking that a door is locked once before leaving home is common. Repeatedly returning to check the lock because of overwhelming doubt, even after knowing it has been checked, may be more consistent with an OCD pattern when it causes significant distress or disrupts daily activities.
Some people with OCD recognize that their thoughts or behaviors seem excessive, while others may have less awareness that the symptoms are unreasonable. Children may also experience OCD differently and may not understand why certain rituals feel necessary.
What are the different obsessive compulsive disorder types?
There is no single pattern that describes every person’s OCD. Obsessive compulsive disorder types are often discussed according to the themes of the obsessions and compulsions, such as contamination, checking, symmetry, harm, or intrusive taboo thoughts.
Common symptom themes can include:
- Contamination and cleaning: fears about germs, illness, or contamination followed by repeated cleaning or washing
- Checking: repeated checking related to locks, appliances, mistakes, safety, or possible harm
- Symmetry and ordering: a strong need for objects or actions to be arranged in a particular way
- Harm-related fears: intrusive fears about causing or experiencing harm
- Religious, sexual, or other intrusive thoughts: unwanted thoughts that conflict with a person’s values or cause significant distress
These themes are not separate diagnoses for every individual. OCD symptoms can change over time, and one person may experience more than one theme. NIMH also notes that symptoms can worsen during stressful periods.
What is an obsessive-compulsive disorder test?
An obsessive-compulsive disorder test is generally a screening questionnaire or assessment used to identify possible OCD symptoms; it is not, by itself, a definitive diagnosis. MedlinePlus explains that health care providers may ask about symptoms and medical history and may use an OCD test or refer someone to a mental health professional for further evaluation.
A screening tool may ask about:
- Recurring unwanted thoughts or urges
- Repetitive behaviors or mental rituals
- The amount of distress caused by symptoms
- How much time symptoms take
- Whether symptoms interfere with everyday activities
For example, the International OCD Foundation provides an OCD screener designed to identify people who may benefit from further diagnostic assessment. A positive screening result indicates that additional evaluation may be appropriate; it does not replace a professional diagnosis.
When should you get a test for obsessive compulsive disorder?
A test for obsessive compulsive disorder may be worth discussing with a health care professional when intrusive thoughts or repetitive behaviors are persistent, difficult to control, or interfering with daily life.
Professional evaluation may be particularly appropriate when you:
- Spend substantial time checking, cleaning, counting, arranging, or performing mental rituals
- Feel unable to stop repetitive behaviors even when you want to
- Experience significant distress because of intrusive thoughts
- Avoid people, places, or activities because of OCD-related fears
- Have difficulty concentrating on work, school, relationships, or daily responsibilities
OCD can sometimes resemble or occur alongside other mental health conditions. NIMH recommends discussing symptoms with a health care provider, who can consider medical history and other possible explanations and refer the person for further mental health evaluation when needed.
How is OCD diagnosed?
OCD is diagnosed through a professional evaluation rather than through one laboratory test or online questionnaire. A health care professional considers the person’s symptoms, their impact on daily life, medical history, and whether another condition could better explain the symptoms.
A screening questionnaire can be useful as an initial step, but it should not be used to self-diagnose. An evaluation is especially important when symptoms are severe, changing, or affecting everyday functioning.
When should you seek help for OCD symptoms?
You should consider professional help when OCD symptoms are causing significant distress, taking substantial time, or making it harder to work, study, maintain relationships, or complete everyday activities. OCD is treatable, and evidence-based treatment can help people manage symptoms and improve daily functioning.
NIMH identifies psychotherapy, medication, or a combination of treatments as approaches used for OCD. Cognitive behavioral therapy (CBT), including exposure and response prevention (ERP), is among the established psychotherapy approaches used to treat OCD.

FAQS
What is obsessive-compulsive disorder?
Obsessive-compulsive disorder (OCD) is a mental health disorder involving recurring, unwanted thoughts, urges, or mental images called obsessions, along with repetitive behaviors or mental acts called compulsions. These symptoms can be difficult to control and may cause significant distress or interfere with work, relationships, school, or daily activities.
What is obsessive-compulsive personality disorder?
Obsessive-compulsive personality disorder (OCPD) is a personality disorder characterized by a persistent preoccupation with order, perfectionism, rules, and control. OCPD is different from OCD. People with OCD generally experience unwanted intrusive thoughts and feel driven to perform compulsions, while people with OCPD tend to view their rigid standards, routines, or need for control as appropriate or necessary.
What is obsessive-compulsive disorder?
Obsessive-compulsive disorder is a long-lasting condition characterized by uncontrollable, recurring obsessions, compulsions, or both. Obsessions can include intrusive fears or unwanted thoughts, while compulsions can include repeated checking, cleaning, counting, arranging, or mental rituals. OCD is diagnosed through a professional assessment rather than by symptoms alone or a single online test.
What causes obsessive-compulsive disorder?
The exact cause of OCD is not fully understood. Research suggests that genetic factors, brain biology and functioning, and environmental influences may contribute to the development of OCD. Having a family history of OCD can increase risk, but no single factor determines whether someone will develop the disorder.
How do you treat obsessive-compulsive disorder?
OCD is commonly treated with psychotherapy, medication, or a combination of both, depending on the person’s symptoms and clinical needs. Cognitive behavioral therapy (CBT), particularly exposure and response prevention (ERP), is an established psychotherapy approach for OCD. Certain medications, including some antidepressants, may also be used. A qualified mental health professional can evaluate symptoms and discuss appropriate treatment options.
Closing statements
Understanding the symptoms of obsessive compulsive disorder can help you recognize persistent obsessions and compulsions. OCD can involve intrusive thoughts, repeated behaviors, or mental rituals that interfere with daily life. An OCD screening test may identify possible symptoms but cannot provide a diagnosis on its own.
Professional evaluation can help determine whether symptoms are related to OCD and identify suitable treatment options. With appropriate care, OCD symptoms can be managed through evidence-based treatments such as therapy, ERP, medication, or a combination.
