Introduction to Item Response Theory (IRT) and Computer Adaptive Testing

Introduction to Item Response Theory (IRT) and Computer Adaptive Testing

Wednesday, January 20, 2021 (5:00 PM - 6:00 PM) (CST)

Description

Host: Richard Gershon, PhD, Northwestern University

Are you new to PROMIS®? Join us for this introductory didactic session on the theory and rigorous methodology used in developing PROMIS measures and testing their validity. The growing emphasis on patient-centered care has increased the demand for high-quality data from patient-reported outcome (PROMIS) measures. Traditionally, the development and validation of these measures have been guided by classical test theory. However, Item Response Theory (IRT), an alternate measurement framework, offers promise for addressing practical measurement problems found in health-related research that have been difficult to solve through classical methods.This recorded session from PHO's PROMIS Training Workshop will be followed by live Q&A with Dr. Gershon.

Dr. Gershon is Vice Chair for Research, Department of Medical Social Sciences, and a Professor of Medical Social Sciences and Preventive Medicine (Health and Biomedical Informatics) at Northwestern University Feinberg School of Medicine, Chicago, Illinois.
