## Work

Prof. Wittchen is a basic and clinical researcher, focusing on the identification of causal factors for mental disorders by combining clinical psychological and psychiatric paradigms and methods with epidemiological approaches and methods. His groundbreaking studies on the course and outcome of treated and untreated anxiety and affective disorders have advanced the knowledge and improved treatment of anxiety (panic attacks, panic disorder, agoraphobia, GAD) and affective disorders particularly by developing “symptom progression” and “comorbidity” models. These studies led to the development of numerous psychotherapy manuals for anxiety and substance use disorders that after a series of randomized clinical trials have become the state-of-the-art manuals for various disorders. They also led to subsequent studies in which he explored the role of stress, trauma PTSD and substance use as well as the impact of mental disorders on neurological and somatic disease.
He also was PI and Co-PI on a number of studies on the prevalence, effects, course, care, therapy, and prevention of mental disorders in Germany and worldwide. His 2005 and 2011 studies "Size and burden of mental disorders in Europe" are among his most cited recent works.
Wittchen conducts aetiological basic research on anxiety disorders, depressive disorders, stress and substance-related disorders as well as on related physical disorders. Wittchen specifically claims to have aided the discovery of generalized anxiety disorder. Fields of his studies include frequency, burdening effects, progress, treatment, therapy and prevention of mental disorders.
Since the late 90's, Wittchen has been author and co-author of the German edition of the DSM-IIIR to DSM-5 revision and he contributed substantially to the development of diagnostic instruments, such as Structured Clinical Interview for Mental Disorders (SKID) and Computer-aided International Diagnostic Interview (CIDI).
With over 840 (2018) peer review publications, he has been awarded the status of “Highly Cited” in Web of Science since the late 90's and is listed by Thomson Reuters among the World's Most Influential Scientific Minds (2015).

## Allegations of data fabrication and investigation

In 2019, Buzzfeed News Germany published allegations that Wittchen had ordered junior colleagues to fabricate data in a 2016–2018 survey of German psychiatric facilities. In response, Technische Universität Dresden launched a two-year investigation.
The investigatory commission's report indicated that Wittchen had ordered colleagues to fabricate data for 20 (of 93) facilities surveyed in the study, and had afterwards sought to conceal the manipulation by altering documents and intimidating whistleblowers and university administrators. The report also detailed an allegation that Wittchen had employed his daughter in the project for two years, though she was never witnessed working on the project. Following the report, Wittchen's contract with Ludwig Maximilian University was suspended. As of April 2021, Technische Universität Dresden is pursuing further investigations, and the Dresden public prosecutor's office has also launched an inquiry.
