The resistance against obsessions items and obsession free-interval items are highlighted to emphasize the primary difference between the 2 measures. As all of the patient’s symptoms fell within the mild to moderate range, and the back-coding method was employed, all other scores (including compulsion items) remained the same across the Y-BOCS and Y-BOCS-II and thus are not shown.
