What percentage of the population is estimated to be affected by obsessive-compulsive disorder?

The percentage of the population estimated to be affected by obsessive-compulsive disorder (OCD) is approximately 2-3%. This figure reflects a broad consensus in the mental health field based on epidemiological studies which have assessed the prevalence of OCD across various demographics. The estimate indicates that OCD is not as common as some other mental health disorders but is still significant enough to warrant attention and treatment.

Understanding the prevalence of OCD helps inform healthcare providers and the public about the importance of recognizing symptoms and providing appropriate support for those affected. The other percentages provided in the options either overestimate or underestimate the prevalence based on current research, which underscores the necessity of having accurate data to better address mental health issues in the community.
