A DOCS total score of 18 optimally distinguishes between someone with OCD and someone without a psychiatric diagnosis; while a score of 21 optimally distinguishes between someone with OCD and someone with an anxiety disorder [REF].
In the initial study describing the development and evaluation of the DOCS, the instrument's factorial validity was supported by exploratory and confirmatory factor analyses of 3 samples, including (a) individuals with OCD, (b) those with other anxiety disorders, and (c) non treatment-seeking individuals.
