What Are the Different Types of OCD? Symptoms, Examples, and How Treatment Helps

Have you ever thought that Obsessive Compulsive Disorder (OCD) meant someone was afraid of germs or was a perfectionist and needed things to be a certain way? Have you ever wondered why they couldn’t just stop worrying about something? OCD is a neurological disorder, “with a lifetime prevalence rate of approximately 3%, (that) will afflict up to 10 million Americans at some point in their lives” (Deusser et al., 2025). 


OCD has two parts to it, the obsessions and the compulsions. Obsessions are intrusive thoughts, images, or urges that are often driven by doubt and trigger fear or anxiety. Compulsions are the behaviors or rituals to try and prevent a feared outcome. An OCD subtype relates to a particular fear, with its own specific obsessions and compulsions. The types of obsessions and compulsions one experiences can be similar across subtypes and also vastly different at the same time. While contamination fears and

perfectionism might be the most commonly recognized subtypes, there are several other subtypes, outlined below. Note: A common word detailed throughout the following subtypes, is reassurance seeking. Reassurance seeking refers to an individual who asks someone else for repeated validation. 


1. Contamination 


○ This subtype revolves around intrusive thoughts, often about germs, and subsequent behaviors aimed at preventing a feared outcome of being contaminated. For example, someone may have unwanted and intrusive thoughts about getting sick and may feel the need to wash their hands excessively. 


2. Checking 


○ This subtype involves a feared obsession, usually related to harm, that elicits repetitive checking of objects, such as whether the door is locked, the stove is off, or something is unplugged. For example, someone may question if they locked the door and the compulsion would be checking if the door is locked, possibly three or four times (or more). 


3. Purely Obsessional (Pure O) 


○ This subtype is a term used to describe presentations in which compulsions are primarily mental rather than outwardly visible. 

Compulsions usually manifest as internal behaviors. For example, a compulsion might look like praying or mentally reviewing a situation.


4. Just Right 


○ This might look like things needing to be symmetrical or to feel “perfect”. For example, this could look like arranging materials in a certain order, replaying a conversation in your head, or redoing a task that does not feel perfect to the individual. 


5. Hoarding 


○ This subtype involves difficulty with throwing or giving away items, usually fueled by fears that it will lead to loss, regret or harm. Unlike hoarding disorder, this pattern is driven by intrusive thoughts and anxiety, with saving behaviors performed as compulsions to relieve distress.


6. Taboo


○ These intrusive thoughts center on topics typically viewed as unacceptable, such as thoughts of violence and pedophilia. For example, compulsions may include hiding objects, seeking reassurance, or avoiding certain people and places. (Other subtypes included with this are violent obsessions, pedophile obsessions, postpartum obsessions, incest obsessions and bestiality obsessions). 


7. Harm 


○ This subtype relates to a fear of harm to oneself or others. Intrusive thoughts cause the individual marked distress. For example, someone may have unwanted thoughts about hurting others and feel the need to avoid certain people, places, or objects. 


8. Relationship 


○ Obsessions are related to doubt about your current romantic relationship and common compulsions may involve reassurance-seeking or analyzing your relationship to someone else's relationship. For example, someone might worry if they are in the right relationship and compulsions might look like reassurance-seeking about the relationship or confessing doubts. 


9. Scrupulosity

 

○ This subtype relates to moral or religious guilt over perceived wrongdoing. For example, someone might worry that they are not a good person or that their God is mad at them and need to atone, engage in prayer or avoid all together. 


10. Existential 


○ This subtype involves unwanted and distressing thoughts about life’s fundamental questions. For example, a common obsession might be wondering about one's existence, and compulsions could include avoiding certain things or engaging in excessive research. 


11. Sensorimotor 


○ This subtype involves noticing and having an intense focus on bodily functions like breathing, that become bothersome to the individual. For example, someone may become aware of their partner's breathing and become aggravated with the noise. 


12. False memory


○ When an individual is convinced that they did something wrong, despite the absence of proof. For example, compulsions may revolve around seeking reassurance or questioning different parts of someone's life.


13. Sexual orientation

 

○ This subtype relates to someone who may be experiencing intrusive and unwanted doubt about their sexual orientation. Someone may question if they are attracted to members of a different sex than they originally thought. For example, this might look like checking in with yourself for any physical reactions when someone of the same or different sex walks by. 

While the obsessions and compulsions may differ due to the specific subtype, the common theme of each is that it is distressing to the individual experiencing the intrusive thoughts. Below are common treatments that can help individuals manage the different symptoms of OCD. 


● Exposure and Response Prevention (ERP), a type of cognitive behavioral therapy, that involves gradual exposure to feared stimuli. By creating a hierarchy of different exposures and intensities, you and your therapist can practice both imaginal and in vivo (real-life) exposures. ERP involves sitting with uncertainty and discomfort at times. One study found that, “Only 2% of the patients with OCD had documented evidence in their medical record of receiving exposure and response prevention (ERP) therapy, the specific form of cognitive behavioral therapy (CBT) that is the most effective treatment for OCD. “ (Deusser et al., 2025). If seeking a therapist, this is something you can ask if they are trained in. 


● Inference-based cognitive therapy (I-CBT) is a form of CBT that focuses on inferential confusion. I-CBT helps identify where reality, and imagination cross over. I-CBT helps to return to a lived reality and reclaim trust in the senses. I-CBT can be especially helpful for someone with predominantly mental compulsions, individuals with minimal insight, or those who might feel more comfortable starting with I-CBT over ERP, or need a break from ERP.


● Selective Serotonin Reuptake Inhibitors: Medication aimed at increasing serotonin levels, which regulates important areas of the brain like cognitive functions and can help with mood. SSRIs are most effective when used with ERP. 

If you are feeling overwhelmed, lost, or confused, reach out to a mental health therapist who specializes in OCD. They can provide you with the necessary psycho education to help you learn and understand the doubt stemming from the obsessions and compulsions.
