OCD (Obsessive-Compulsive Disorder)
OCD (obsessive-compulsive disorder) involves recurring unwanted thoughts (obsessions) and repetitive behaviors or mental acts (compulsions) done to reduce distress.

Screening tools like the OCI-R and MOCI measure symptom severity; diagnosis requires clinical evaluation.
