About
Dr. Donald Addington serves as a Clinical Professor in the Department of Psychiatry at the University of Calgary's Cumming School of Medicine, with full memberships at the Hotchkiss Brain Institute and Mathison Centre for Mental Health Research and Education. His academic career spans over 50 years, focusing on transforming mental health service delivery for schizophrenia and early psychosis through evidence-based tools and standards.
His educational credentials include:
- MBBS in Medicine, University of London (1972)
- MRCPsych in Psychiatry, Royal College of Psychiatrists (1976)
- FRCPC in Psychiatry, Royal College of Physicians and Surgeons of Canada (1982)
Dr. Addington's research integrates clinical psychiatry with health services evaluation to develop practical measurement systems. He pioneered internationally adopted instruments including depression assessment scales for schizophrenia and fidelity metrics for psychosis services, creating bridges between clinical practice, policy development, and funding mechanisms. His work establishes standardized approaches for evaluating mental health service accessibility, quality, and outcomes across diverse healthcare systems.
His publication trajectory reveals consistent innovation in measurement science, evolving from the foundational Calgary Depression Scale (1990) to contemporary fidelity scales for early psychosis intervention (FEPS-FS/CHRP-FS). These works establish global benchmarks for service quality assessment, with applications spanning clinical practice guidelines, performance measurement, and cross-system outcome comparison through initiatives like the ICHOM Psychotic Disorders standard set.
Dr. Addington's scientific recognition includes:
- Excellence in Clinical Teaching, PAIRA (1996)
