The Investigation of Transdiagnostic Role of Obsessive Beliefs: Comparison of Clinical Groups Diagnosed with Obsessive Compulsive Disorder, Anxiety Disorders and Depression with University Students.

Objective: The present study aimed to investigate whether the dysfunctional obsessive beliefs are specific to obsessive-compulsive disorder (OCD) using three different clinical groups including OCD, depression, and anxiety and a control group of university students.

Method: The participants of the study comprised three patient groups with OCD (n=53), major depressive disorder (MDD, n=67), anxiety disorders (AD, n=73), and a group of university students (n=477). The short version of the Obsessive Belief Questionnaire (OBQ-20) was used to measure obsessive beliefs.
