SEMINAR: Evolutions in the Meaning of “Validity” for Measures in Health Care Research: From Accuracy to Argument

Since the 1970s, the field of health measurement has been informed by methodological developments in educational and psychological measurement. In this talk I will discuss how validity theory has changed over the past 4 decades in education and psychology, how these changes have or have not been reflected in the field of health measurement, and how modern validity theory may address current struggles within health measurement.
