Power, reliability, and estimation errors in lifespan biomarker research.
Suzanne Segerstrom, PhD, MPH
Professor of Psychology, Department of Psychology, University of Kentucky
The idea of “physiometrics” – the physiological equivalent of psychometrics – seems to have been around for at least three decades. Although the validity of physiological measures is a major research topic, there has been less attention to variability, generalizability, and measure reliability across the lifespan. Inadequate measurement of biomarkers can result in erroneous conclusions. Dr. Segerstrom will present data on biomarker measurement, primarily focusing on salivary cortisol, and describe ways to both compensate for and use variability.
