In this in-depth workshop, participants will learn the phenomenology of OCD, core definitions of obsessions and compulsions, and methods for distinguishing between obsessions and mental rituals. Participants will gain a solid understanding of common comorbid conditions and differential diagnosis skills. Common symptom clusters of obsessions and compulsions (e.g., contamination obsessions and cleaning compulsions) will be outlined as defined by the Yale-Brown Obsessive Compulsive Scale (Y-BOCS) and the Children’s Yale-Brown Obsessive Compulsive Scale (CY-BOCS).
Learning Objectives
List the core features of OCD phenomenology, clearly defining and differentiating between obsessions and compulsions
Describe the four components of the OCD cycle (obsessions, distress, compulsions, relief) based on a CBT conceptualization
Interpret CYBOCS scores for use in diagnostic assessment
Identify the seven categories of compulsions, as defined by the YBOCS/CYBOCS
