Transdiagnostic Approach to Generalised Anxiety Disorder and Major Depressive Disorder

This dissertation explores the transdiagnostic approach to treating anxiety disorders, particularly generalised anxiety disorder (GAD), and unipolar depressive disorders, notably major depressive disorder (MDD). The comorbidity of these conditions is considerably high, which complicates treatment and is associated with more severe symptoms, lower quality of life and other complications. This review investigates two major approaches: the Unified Protocol and the Wellbeing Course. These methods offer comprehensive treatment for individuals with comorbid anxiety and depressive disorders by addressing the transdiagnostic features that occur in these disorders. The review examines the efficacy and benefits of these approaches compared to traditional diagnosis-specific treatments, highlighting the potential for transdiagnostic therapies to improve outcomes for individuals struggling with comorbid disorders.
