OCD Themes and Subtypes: A Clinical Directory
OCD can attach to harm, relationships, morality, memory, contamination, health, the body, identity, death, and many other topics. This hub organizes the published theme guides while maintaining a clinical focus on the pattern that sustains OCD.
The Theme Changes. The OCD Cycle Is What Treatment Targets.
OCD themes describe what the fear is about, but treatment depends on how the cycle functions: triggers, meaning, compulsions, avoidance, and short-term relief. Similar themes can operate differently across people, which is why assessment comes before treatment planning.
Six Guides People Often Look For First
These are entry points, not a complete map. The full directory below organizes every verified published theme page without turning the entire hub into a wall of cards.
Harm OCD
Intrusive violent thoughts, avoidance, checking, and reassurance loops that make danger feel personal.
Relationship OCD
Doubt about love, attraction, compatibility, or whether the relationship feels certain enough.
Contamination OCD
Germs, illness, disgust, chemicals, or emotional contamination loops that pull people into washing and avoidance.
Scrupulosity OCD
Religious, moral, or ethical fear is organized around guilt, confession, reassurance, and impossible certainty.
Taboo Intrusive Thoughts
Harm, sexual, religious, moral, and identity-based obsessions, people often feel most afraid to say out loud.
Mental Rituals
Covert compulsions like mental review, neutralizing, self-reassurance, and checking feelings.

Assessment looks for:
ERP is adapted through functional assessment and used when clinically appropriate. The goal is not to force the same exposure script on every presentation; it is to design practice around the actual learning target.
