Abstract:
This response to a reader's comment on our paper "The Global Assessment of OCD" addresses the critique regarding the stated prevalence of OCD as the fourth most common mental disorder. We acknowledge an oversight in our initial reference, discuss the variable prevalence rates from various studies, and highlight the significant disability caused by OCD. We have requested a correction to the original citation to reflect more recent findings, aiming to ensure accuracy in the discourse on OCD's public health impact.
