The Yale-Brown Obsessive-Compulsive Scale-Second Edition (Y-BOCS-II) is a more comprehensive measure for assessing the severity of obsessive-compulsive disorder symptoms, especially in severely ill patients. It maintains strong consistency with the original scale when assessing patients with mild to moderate symptoms. By adding Y-BOCS item 4 and back-coding, both Y-BOCS and Y-BOCS-II scores can be obtained within one assessment, allowing for more robust data collection and comparability across studies.
The Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) is a widely used measure for assessing the presence and severity of obsessive-compulsive disorder symptoms. The Yale-Brown Obsessive-Compulsive Scale-Second Edition (Y-BOCS-II) was developed, in part, to more comprehensively evaluate symptom severity, especially in extremely ill patients, and improve consistency in detecting and incorporating avoidance behaviors. We present 3 case studies that demonstrate the enhanced ability of the Y-BOCS-II to: (1) detect fluctuations in symptom severity among extremely ill patients, (2) systematically incorporate avoidance variables for more accurate ratings, and (3) maintain strong convergence with the Y-BOCS in assessing patients presenting with mild to moderate symptoms. In addition, we outline how to obtain both Y-BOCS and Y-BOCS-II scores within 1 administration by adding Y-BOCS item 4 to the Y-BOCS-II assessment, then back-coding the Y-BOCS-II ratings to Y-BOCS ratings and using Y-BOCS item 4 in place of Y-BOCS-II item 2. The use of this method allows for more robust data collection while providing comparability across the literature.
