Six themes ranked, your leading one written out, and the page that goes deeper
People who search for OCD themes or OCD subtypes usually already know what OCD is and want to know which version of it describes them. This quiz answers that: 30 questions over six obsession themes, with all six ranked, your leading one written out in what it actually looks like day to day, and a pointer to your second and third so you can read them together. It deliberately does not score severity, because the theme and the severity are different questions. It is a screening for adults, for education and self-reflection, and it is not a diagnosis.
Six themes, not one label
Contamination, harm and responsibility, symmetry and just-right, unwanted intrusive thoughts, relationship doubt, and saving. Five questions each, so no theme can win on question count.
All six ranked, not just the winner
Most people with OCD carry more than one theme at a time. The result ranks all six and writes out the leading one, and it tells you to read the two behind it, because treating only the loudest theme tends to miss where the rest of the time goes.
A route, not a verdict
Each theme links the test that goes deeper on it, and the result points at our OCD Test for a severity score. The themes are descriptive, and the page says so rather than implying they are diagnostic categories.

The 6 patterns this test measures
- Contamination: Dirt, germs, illness and the fear of spreading it.
- Harm and responsibility: Fear of causing a disaster by acting or by failing to act.
- Symmetry and just-right: Order, evenness, counting, and repeating until it feels correct.
- Unwanted intrusive thoughts: Thoughts that clash with your values, and the question of what they mean about you.
- Relationship doubt: Am I with the right person, do I really feel it, and the checking that follows.
- Saving and hoarding: Cannot discard, dread of needing it later, and keeping what has no use.
If nothing is endorsed, every pattern scores the same, or the leading patterns tie, the result says so instead of naming a single pattern.
How the themes are scored
The quiz is 30 statements, five for each of the six themes, each rated from 0 to 4. The engine adds up each theme separately and ranks all six, and the write-up you get is for your highest one, which also points you at your second and third bars. Equal question counts per theme matter more than they sound: many online theme quizzes carry twice as many contamination questions as anything else, which makes contamination the most likely result for anyone who answers anything. Five apiece means the ranking reflects your answers rather than the design.
There is no total and no severity band, and that is deliberate. How much a theme is affecting you is a separate question from which theme it is, and running them together produces a number that answers neither. For a severity score, our OCD Test scores the compulsion areas that the OCI-R covers and gives you a band. The sensible order is this page first if you do not know what your obsessions are about, then the severity screen, then the page for your leading theme.
What a theme is, and what it is not
Themes are descriptions of content. They are not subtypes in the DSM-5-TR, which lists obsessive-compulsive disorder as one diagnosis with specifiers for insight and tic history and no theme categories at all. Clinicians and researchers use theme language constantly because it is useful for planning treatment and for explaining the condition, and the dimensional research, particularly the work behind the Dimensional Obsessive-Compulsive Scale and the multidimensional model Mataix-Cols and colleagues described in 2005, supports treating these contents as dimensions rather than as boxes. A dimension is something you have more or less of. A box is something you are in. The research supports the first.
Three things follow from that. Most people with OCD carry more than one theme at once, which is why this page ranks all six instead of naming one and stopping. Themes shift across a life, and a follow-up study of adults with OCD found the overall symptom structure fairly stable while the specific content people presented with changed, so a leading theme describes this period rather than a permanent category. And the engine underneath is the same whatever the content: an intrusive thought, an inflated sense of what it means, and a compulsion that relieves it briefly while teaching you to need it again. That is why exposure and response prevention works across themes, and why the theme mostly determines what the exposure looks like rather than whether treatment will help.
How this differs from our OCD test
They score different halves of the same condition. Our OCD Test is built on the areas the Obsessive-Compulsive Inventory Revised covers, which are forms of compulsion: washing, checking, ordering, obsessing, hoarding and neutralizing. It answers how much, and it gives you a severity band you can take to a clinician. This page asks what the obsessions are about: the content that the fear attaches to. The distinction is not academic. Two people can both score in the moderate range on the severity screen and need completely different exposures, one around touching surfaces and one around tolerating a thought about their partner.
In clinical practice the tool that maps content is the Yale-Brown Obsessive Compulsive Scale symptom checklist, published by Goodman and colleagues in 1989, which a clinician works through with you to identify which obsessions and compulsions are present before scoring severity. It is a clinician-administered instrument and it is not reproduced here, in whole or in part; nor is the Dimensional Obsessive-Compulsive Scale, which is named here only to credit the dimensional research. The 30 items on this page are our own, and no published norms apply to them.
What to do with your result
Take the severity screen next. OCD Test (Obsessive-Compulsive Disorder) gives you a band across the compulsion areas, and that is the number worth bringing to a clinician, not the theme ranking. Then read the page for your leading theme, since each of the six has one: Pure O OCD Test for unwanted intrusive thoughts, Harm OCD Test for fears of causing harm, Relationship OCD (ROCD) Test for relationship doubt, and Hoarding Disorder Test (HRS-SR) for saving and clutter. Intolerance of Uncertainty Test measures the engine that sits under all of them, which is the inability to settle without being sure, and it is often the most useful single read after this page.
If what you recognized here is real, the treatment is specific and it works. Exposure and response prevention has the strongest evidence of any psychological treatment for OCD across themes, usually delivered over a few months of weekly sessions, and medication is a well-supported option alongside or instead of it. The thing to look for in a therapist is explicit experience with ERP for OCD rather than general anxiety work, and it is a fair question to ask in the first message. One practical note for the intrusive-thoughts theme: reassurance from a therapist is a compulsion like any other, and a clinician who knows OCD will decline to give it, which is a sign you have the right person rather than the wrong one.
Methodology & sources
The 30 statements on this page are original, written for this test, five for each of the six themes. No clinical instrument is reproduced here, in whole or in part. The Yale-Brown Obsessive Compulsive Scale symptom checklist (Goodman and colleagues, 1989) is the clinician-administered tool that maps obsession and compulsion content, and the Dimensional Obsessive-Compulsive Scale (Abramowitz and colleagues, 2010) is the self-report measure of symptom dimensions: both are named here to credit the research and to be clear about what this page is not. Four of the six themes follow the content dimensions that scale measures, which it names as concerns about germs and contamination, concerns about being responsible for harm, injury or bad luck, unacceptable thoughts, and concerns about symmetry, completeness and exactness. Those are also the dimensions the multidimensional model described by Mataix-Cols and colleagues in 2005 identifies. The two others, relationship doubt and saving, are added because both are well described in the OCD literature and both are what readers search for, and the Y-BOCS symptom checklist covers them as content categories. The theme groupings and the items are ours and are not validated subscales.
There is no severity score and no band on this page, by design: the result is a ranking of six themes, and the engine ranks all six and writes up the leading one, with that write-up telling you to read your second and third bars as well. Equal item counts per theme keep the ranking honest, since an unbalanced quiz returns whichever theme has the most questions. Themes are descriptive rather than diagnostic: the DSM-5-TR recognizes one obsessive-compulsive disorder with specifiers for insight and tic history and no theme subtypes, so a leading theme here is a description of this period rather than a category you belong to. This page screens for education and self-reflection, and only a licensed clinician can assess OCD.

OCD Themes Quiz: Rank Your Six Obsession Themes FAQ
Are OCD subtypes real?
The themes are real and useful, and they are not formal subtypes. The DSM-5-TR lists one obsessive-compulsive disorder, with specifiers for how much insight a person has and whether there is a tic history, and no theme categories. What the research supports is dimensions: Mataix-Cols and colleagues described a multidimensional model in 2005, and the Dimensional Obsessive-Compulsive Scale measures symptom dimensions rather than types. So contamination OCD and harm OCD are accurate descriptions of what someone's obsessions are about, and nobody is diagnosed with one.
What if two themes scored almost the same?
That is the common result rather than the odd one. Most people with OCD carry more than one theme, which is why this page gives you three rather than one. Treat the ranking as a description of where your attention is going at the moment, not as a sorting. If two are level, read both interpretations and start with whichever is costing you more time, since the treatment approach is the same across themes and only the content of the exposures changes.
Does this test score how severe my OCD is?
No, deliberately. This page answers which theme rather than how much, and mixing them produces a number that answers neither. For a severity score, our OCD Test covers the areas the Obsessive-Compulsive Inventory Revised measures, which are forms of compulsion, and gives you a band you can take to a clinician. The sensible order is this page to find the theme, then that page for the severity, then the test for your leading theme.
Can my themes change over time?
Yes, and that is well documented. A two-year follow-up study of adults with OCD found the broad symptom structure fairly stable while the specific content people presented with shifted, and clinicians see the same thing over longer spans: contamination in your twenties, relationship doubt in your thirties, harm fears after a child is born. The condition is the same machinery wearing different clothes. A leading theme describes this period of your life, and a change in theme is not a new condition or a sign of getting worse.
Does my theme change what treatment I need?
It changes what the exposures look like, not whether treatment works. Exposure and response prevention has the strongest evidence of any psychological treatment for OCD and works across themes, because it targets the compulsion rather than the content. What differs is the practical content: tolerating an unwashed hand, a door checked once, a thought left unexamined, or a feeling about a partner left unmeasured. For the intrusive-thought themes the compulsions are mostly mental, so the work includes dropping reassurance seeking and mental reviewing, which a therapist experienced with OCD will recognize immediately.
Is the test really confidential?
Yes. It runs entirely in your browser. Your individual answers are scored in your browser and are never sent to us or linked to you. They stay in this tab so you can return to your result, and closing or clearing the tab clears them. If you ask us to email the PDF, we receive your summary scores with your email address, never your individual answers. No account is needed.
