The importance of transdiagnostic approach in psychopathology and psychotherapy

In recent years, the use of the “transdiagnostic” term and construct has been considered in the field of psychopathology and psychological treatments. Transdiagnostic models and treatments were developed in contrast to single-diagnosis protocols. Transdiagnostic in psychopathology means addressing common underlying mechanisms in a range of comorbid disorders and in the field of treatment means we provide treatment protocols that do not merely intervene based on specific diagnoses and treat these underlying mechanisms. In this regard, the present article aims to explain the different meanings of transdiagnostic construct and to present a brief overview of two proposed transdiagnostic models and treatments; unified therapy and emotion regulation therapy. Finally, considering the challenges of comorbidity associated with psychiatric disorders and the ease of dissemination and treatment in transdiagnostic status, the advantages and disadvantages of this approach are discussed.
