11th INTERNATIONAL CONGRESS and 16th NATIONAL of CLINICAL PSYCHOLOGY

Since the 1980s, diagnosis and classification systems, such as the DSM-5 and ICD-10, have classified psychopathologies as distinct, independent, and categorical constructs. The classification systems are based on the basic assumption that each mental disorder has a specific and unique clinical feature that does not overlap with the other disorders. However, research on disorder dimensionality and comorbidity indicate that these assumptions are not justified and highlight common cognitive-behavioral, interpersonal and biological factors across different disorders that may play an important role in the development and maintenance of the symptoms. For that reason, many researchers begin to conduct their studies in the frame of “transdiagnostic” model.  Transdiagnostic model is based on a common underlying mechanism that helps to explain, especially, comorbid disorders and improve the simplest treatment protocol for many psychopathologies in order to save the time and effort. The aim of the symposium is to discuss whether specific cognitive variables (e.g., intrusive thoughts and obsessive beliefs), and behaviors (e.g., reassurance seeking and thought control strategies) have transdiagnostic feature across different psychopathologies.
