Christina Kelsey Zigler

Dr. Zigler is an independent investigator dedicated to improving the ways we measure patient-centered, meaningful health states, specializing in pediatrics, rare diseases, and clinical trials. She also is a methodological co-investigator who supports the application of novel statistical approaches and measurement strategies across a diverse array of studies.

Her methodological expertise includes established qualitative and quantitative techniques (i.e. concept elicitation, cognitive testing, classical test theory, item-response theory) alongside innovative methods (i.e. novel ways to identify meaningful change), to ensure the measures are ultimately centered in the patients’ meaningful experiences. Further, she works in a variety of populations and contexts, including pediatrics, where patient-reported outcome measures empower children to report directly on their own health status, and rare diseases, where a creative and pragmatic approach to measure development is necessary and patient-centeredness is essential.
