Common OCD Themes
OCD Can Fixate on Anything
Obsessive Compulsive Disorder (OCD) can take many different forms and the themes can latch on to literally anything! There is no topic, thought, or fear that is off-limits. While you may have heard of contamination, harm, or checking rituals, these are just a few examples. If your own experience doesn't match a named theme, that doesn't mean it isn't OCD.
What unites every presentation is the underlying process. OCD is characterised by intrusive thoughts, images, urges, sensations, or doubts that trigger distress and uncertainty. In response, people often engage in compulsions, avoidance, reassurance seeking, rumination, and attempts to gain certainty.
While the specific content can vary from person to person, the underlying difficulties are often the same: at the core there is excessive doubt, and a strong urge to feel certain before moving on. For this reason, OCD is often considered to be the Disorder of Doubt.
OCD Themes Are Not Diagnoses
Many people experience more than one OCD theme, and themes often change over time. The specific content of OCD is less important than the processes that maintain it.
If you recognise yourself in one or more of these themes, a comprehensive assessment can help determine whether OCD or a related condition may be contributing to your difficulties and identify the most appropriate treatment options.
Contamination OCD
People with contamination OCD experience fears about germs, illness, bodily fluids, chemicals, toxins, or environmental contamination. Common compulsions include excessive washing, cleaning, avoiding perceived contaminants, or seeking reassurance about cleanliness and safety.
Harm OCD
Harm OCD involves intrusive thoughts, images, or urges about accidentally or intentionally causing harm to oneself or others. Despite these fears, people with Harm OCD are typically highly distressed by the thoughts and go to great lengths to prevent harm from occurring.
Relationship OCD (ROCD)
Relationship OCD centres on doubts and uncertainty about romantic relationships. People may repeatedly question whether they truly love their partner, whether their partner is "right" for them, or whether the relationship is good enough, often seeking certainty that cannot be achieved.
Sexual Orientation OCD (SOOCD)
Sexual Orientation OCD involves unwanted doubts about one's sexual orientation. Individuals may become preoccupied with analysing thoughts, feelings, attractions, or bodily sensations in an attempt to gain certainty about their identity.
Pedophilia OCD (POCD)
People with POCD experience intrusive fears about being sexually attracted to children despite finding the thoughts distressing and inconsistent with their values. Common compulsions include checking reactions, avoiding children, seeking reassurance, and excessive self-monitoring.
Scrupulosity (Religious or Moral OCD)
Scrupulosity involves fears of being immoral, sinful, dishonest, or offending religious beliefs. Individuals may engage in excessive confession, prayer, mental review, reassurance seeking, or attempts to achieve moral certainty.
Health OCD
Health OCD involves persistent fears about having or developing a serious illness. Unlike ordinary health concerns, individuals often engage in repeated checking, reassurance seeking, symptom monitoring, online searching, or medical consultations to try to reduce uncertainty.
Responsibility OCD
Responsibility OCD involves fears of being responsible for harm, mistakes, accidents, or negative outcomes. People may repeatedly check, seek reassurance, retrace their steps, or review events mentally to ensure nothing bad has happened.
Perfectionism and "Just Right" OCD
People with "Just Right" OCD experience a strong sense that things must feel complete, balanced, symmetrical, or exactly right. They may repeat actions, rearrange objects, reread information, or start tasks over until things feel correct.
Existential OCD
Existential OCD focuses on unanswerable questions about reality, consciousness, existence, free will, or the meaning of life. Individuals often become trapped in endless mental analysis and attempts to find certainty about questions that have no definitive answers.
Real Event OCD
Real Event OCD involves excessive guilt, shame, or doubt about things that actually occurred in the past. Individuals may become stuck analysing past actions, seeking reassurance, confessing, or attempting to determine whether they are a "good" or "bad" person.
Meta OCD (OCD about having OCD)
People with Meta OCD become highly preoccupied with whether their symptoms are “real OCD” or whether they are doing treatment correctly. This can lead to excessive researching, reassurance seeking, and constant self-monitoring of progress, which can itself become part of the OCD cycle.
Sensorimotor OCD
Sensorimotor OCD involves becoming hyperaware of automatic bodily processes such as breathing, swallowing, blinking, or heartbeat. Individuals may become distressed by the feeling that they cannot stop noticing these sensations.
Relationship with Self OCD
Some people experience OCD focused on identity, personality, values, or their sense of self. They may repeatedly question who they really are, whether they are authentic, or whether certain thoughts reveal something important about their character.
Perinatal OCD
Perinatal OCD occurs during pregnancy or after childbirth and involves intrusive thoughts or fears about harm coming to the baby or oneself. These thoughts are typically distressing and unwanted, and individuals may engage in checking, avoidance, reassurance seeking, or mental reviewing to reduce anxiety. It is important to note that having these thoughts does not reflect intent and is a recognised and treatable form of OCD.
“Optimising” OCD (Perfectionism & Efficiency)
Optimising OCD involves a preoccupation with making decisions, tasks, or routines feel perfectly efficient, correct, or “the best possible version.” Individuals may spend excessive time researching, comparing, rearranging, or mentally reviewing choices to eliminate doubt or improve outcomes. This can significantly delay action and create ongoing uncertainty, even in everyday decisions.
