A Transdiagnostic Model for Depression, Anxiety, and Obsessive-Compulsive Disorder

Depression, obsessive-compulsive disorder (OCD), and anxiety disorders (ADs) can seriously impair functionality. Studies have shown that there are common mechanisms in the emergence of these disorders. This study discussed unpredictability beliefs, family unpredictability, locus of control, intolerance of uncertainty, emotional regulation difficulties, and coping styles. In this study, a model created with these transdiagnostic variables that play a role in the emergence of depression, OCD, and ADs was tested. The sample of the study consisted of 795 people. The model explained a significant part of the variance in psychological symptoms. In addition to various limitations, it is thought that this study has important contributions to the field by examining the relationships between unpredictability beliefs and various variables for the first time, and bringing together many transdiagnostic factors related to psychological symptoms. In addition, it provides valuable information for clinicians as it provides a basis for intervention programs targeting many transdiagnostic mechanisms.
