OCD can attach itself to almost any fear, value, relationship, or uncertainty. The content may look different from person to person, but the underlying cycle is often similar: obsession, distress, compulsion, temporary relief, and renewed doubt.
Contamination OCD
Fear of germs, illness, dirt, chemicals, bodily fluids, or contamination, often with washing, cleaning, sanitizing, avoidance, or repeated checking.
Checking OCD
Repeated worries about safety, harm, mistakes, or responsibility, with checking of locks, appliances, messages, memories, body sensations, or decisions.
Harm OCD
Unwanted intrusive thoughts about harming oneself or others, often with avoidance, reassurance-seeking, checking, mental review, or intense shame.
Scrupulosity
Religious or moral obsessions involving fear of sin, wrongdoing, dishonesty, impurity, or moral failure, often with prayer, confession, mental checking, or reassurance-seeking.
Symmetry and "Just Right" OCD
A strong need for order, balance, exactness, or a "just right" feeling, often with arranging, repeating, counting, touching, or restarting.
Pure O
Primarily obsessional OCD, where compulsions may happen internally through mental review, reassurance-seeking, analyzing, checking feelings, or trying to neutralize thoughts.
Relationship OCD
Constant doubt about feelings, attraction, compatibility, commitment, or certainty in a relationship, often with checking, comparing, confessing, or reassurance-seeking.
Hoarding-Related Concerns
Hoarding disorder is a separate diagnosis, but hoarding symptoms may appear alongside OCD or OCD-like patterns and should be carefully assessed.
