Which of the following best describes compulsions in OCD?

Compulsions in Obsessive-Compulsive Disorder (OCD) are characterized primarily by repetitive behaviors or mental acts that an individual feels driven to perform in response to an obsession or according to rigid rules. These behaviors are aimed at reducing anxiety or preventing a feared event or situation. Although the compulsions do not necessarily have a realistic connection to the feared event, they serve as a coping mechanism to alleviate the intense anxiety caused by obsessive thoughts.

This understanding is crucial for recognizing how compulsions function within the context of OCD. The repetitive nature of these actions highlights the struggle individuals face in managing their anxiety. For example, someone might feel compelled to wash their hands repeatedly to alleviate the irrational fear of contamination. Through this lens, it's clear that the primary purpose of compulsions is to mitigate anxiety, which is accurately described by the choice provided.
