Dr. Donald Addington is a Clinical Professor in the Department of Psychiatry, a member of the Mathison Centre for Mental Health Research and Education and the Hotchkiss Brain Institute. He has been active in research, education, clinical practice administration and advocacy. His research activities focus on access quality and outcome of mental health services with a focus on schizophrenia and early psychosis intervention.
Dr. Addington has developed a number of tools that have had a broad impact on the quality of health care delivery. These include clinical practice guidelines, psychiatric status rating scales, fidelity scales, risk adjustment models and performance measures. In 2016 he published the First Episode Psychosis Fidelity Scale (FEPS-FS) a tool that assesses access and quality of first episode psychosis services. This has been used in 3 large scale projects, one a US Government funded implementation study across 32 states. One a Canadian study in the Early Psychosis Intervention Ontario Network of 40 programs. The third was a national study of Early Psychosis Intervention Programs in Italy. The scale has been updated and revised in 2021 and a manual published by the University of Calgary Press.
Dr. Addington has over 150 peer reviewed publications and has received grants from the National Institutes of Health, Canadian Institutes of Health Research and Alberta Heritage Foundation for Medical Research. He established the psychosis research group at the University of Calgary in 1986, a group that continues to the present time and is now a component of the Mathison Centre. In 1990 he published the Calgary Depression Scale for Schizophrenia which has become the internationally recognized gold standard for the assessment of depression in schizophrenia and has been translated into over 40 languages. Nationally, Dr. Addington has chaired 3 working groups for the development of the Canadian Clinical Practice Guidelines for Schizophrenia published in 1997, 2005 and 2017.
In education, he was an author on a Royal College of Physicians and Surgeons document Core mental health competencies for Physicians. This document is being used as the platform to support the development of core competencies for Royal College specialties and subspecialties. Dr. Addington consults with various Royal College Specialty Trainees Committees to develop specialty specific mental health core competencies. He is also active training researchers, trainees and clinicians in practice.
In clinical practice he has focused on early intervention in schizophrenia. His administrative practice lies in consulting to and providing training to regulators, funders and providers of evidence based services for individuals with a first episode psychosis.He obtained competitive health services grants to support the development and evaluation of the Calgary First Episode Psychosis Services comprised of both First Episode Psychosis clinics and Clinical High Risk for Psychosis clinics for those at clinical high risk of developing schizophrenia. These services have now become established components of Alberta Health Services.
In addition to his research career Dr. Addington was for 11 years the Chairman of the Department of Psychiatry at the University of Calgary and Head Calgary Health Region Regional Clinical Department of Psychiatry. He then served two three year terms as the Board Chair of the Canadian Psychiatric Association. He has served on a number of committees for the Canadian Institutes for Health Information, the Mental Health Commission of Canada, the Royal College of Physicians and Surgeons of Canada and the International Early Psychosis Association. His current administrative practice is in consulting to policy makers, funders, service delivery organizations.

Dr. Addington’s research has spanned and linked clinical and health services research in a way that supports clinical practice, policy and funding. He has developed a number of tools that have had a broad impact on the quality of health care delivery, particularly in the area of schizophrenia spectrum disorders. These include clinical practice guidelines, psychiatric status rating scales, fidelity scales, risk adjustment models and performance measures. In 1990 he published the Calgary Depression Scale for Schizophrenia, which has become the internationally recognized gold standard for the assessment of depression in schizophrenia and has been translated into over 40 language versions. In 2008 he started on the development of sets of performance measures that use scales to assess access, quality and outcome of mental health services. This has resulted in one combined set of quality indicators and one outcome set. In 2016 he published the First Episode Psychosis Fidelity Services Scale (FEPS-FS) a set of performance measures which assess the accessibility and quality of first episode psychosis services. The tool has been revised, updated and published by the University of Calgary Press in 2021 https://press.ucalgary.ca/books/9781773852089/ . The scale uses a five point Likert scale to rate components. This measurement method supports the development of standards which allows individual programs to compare themselves to published standards. It can also be used by service delivery organizations and funders to set standards. The fidelity scale is being used for quality improvement and evaluation in a number of Canadian Provinces and US States. It has also been used in specific research projects as well as in 3 large scale projects. A US Government funded implementation study across 32 states, a Canadian study in the Early Psychosis Intervention Ontario Network of 40 programs. The third was a national study of Early Psychosis Intervention Programs in Italy.
He led the team that developed the International Consortium for Health Outcome Measurement (ICHOM) Psychotic Disorders standard set of Patient Reported Outcome Measures https://connect.ichom.org/standard-sets/psychotic-disorders/. This outcome set with risk adjustment factors, supports both measurement based care and comparison of outcomes across programs, health systems and internationally.
Professor Addington’s current and future research is focussed on three areas:
- Broadening the application of the First Episode Psychosis Services Fidelity Scale
- Development of a linked set of early psychosis intervention services fidelity scales, that cover a broader range of clinical services such as those for patients at Clinical High Risk of developing Psychosis and Bipolar Disorder.
- Testing and application of patient reported outcome measures and measure sets.
