In Vienna, Hans-Ulrich Wittchen was in charge of introduction of behavioral therapy methods at Anton Proksch Institute and Ludwig-Boltzmann Institute. He earned his PhD in 1975 with a thesis on clinical significance of biofeedback methods in the faculty of psychology, Vienna University. In addition he completed his psychotherapy training licensed by the German Behavioral Therapists Association and the Österreichische Gesellschaft zur Förderung der Verhaltenstherapie; in 2000 he received his "Approbation" according to German law.

In 1984, he completed his habilitation for clinical psychology at Ludwig-Maximilians-University Munich with publication and a monograph on "Course and Outcome of Treated and Untreated Anxiety and Depressive Disorders". While remaining head of the MPI-P research department, he was appointed as Professor of Clinical Psychology & Psychotherapy in 1984 at the University of Mannheim, where he founded the “Psychotherapy Outpatient Department” and the Institutes psychophysiological lab. 1989, Hans-Ulrich Wittchen took a sabbatical to support the World Health Organization's (WHO) division of Mental Health and the United States Department of Health and Human Services (ADAMHA) department in completing the WHO-ICD-10[9] classification and the US-DSM-III-R[8] systems, developing diagnostic tools and conducting supplementary studies.

1990 he was appointed as Director of the "Department of Clinical Psychology and Epidemiology" at the MPI-P in Munich. Throughout his professional career, Wittchen repeatedly was "visiting scientist" and "visiting professor" at the National Institute of Mental Health, Bethesda, USA, at the University of Michigan in Ann Arbor, USA and the Harvard University in Boston (US), where he collaborated with Lee Robins, Ron Kessler and Darrel Regier on the development of diagnostic tools and national and international epidemiological surveys.

His contract was suspended in April 2021 following an investigation into allegations of data fabrication, document manipulation, and whistleblower intimidation.

Prof. Wittchen is a licensed psychotherapist and still acts as CEO of the IAP-TU Dresden GmbH.

## 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.
