While OCD occurs in about 2-3% of the population, many more people have obsessive-compulsive traits. These traits do not cause the same level of distress and impairment that is seen in OCD, but the traits are measurable by researchers and can be classified into familiar categories (e.g., cleaning/contamination, symmetry/checking, and rumination). New research in the journal Translational Psychiatryfinds that specific traits, like symmetry and checking behaviors, can be passed on from parents to children, and that genetics plays a role. The researchers believe that by expanding OCD genetics studies to include the relatively larger group of people with OC traits, they can improve the accuracy of future genetics research.
