Objective: Obsessive compulsive disorder (OCD) is probably a heterogeneous condition. To date, research investigating the symptom structure of OCD has generally focused on variable-classification approaches, primarily factor analysis. Our aim was to use the latent class analysis, an advanced individual-classification method, in order to define homogeneous sub-groups based on the Yale Brown Obsessive Compulsive Scale Check List (Y-BOCS CL) assessments within 193 outpatients with OCD.
