An Introduction to Item Response Theory (IRT) for Public Health Professionals
Partnership:1) Statistics Section and 2) the American Statistical Association
Statement of Purpose and Institute Overview:
The purpose of this session is to introduce participants to the theory and application of item response theory (IRT) models and provide experience interpreting the outcomes of analyses and studies employing these models. The course will briefly cover basic psychometric concepts, describing the importance of establishing reliable and valid measurement in public health research, and then focus chiefly on IRT measurement models. Material will cover the Rasch , 2PL, and 3PL models and their associated measurement parameters. Polytomous models will also be similarly addressed. The course will provide examples of the models in real data and describe their interpretation. The program will address the settings and manner in which IRT models may be employed to increase the validity and reliability of public health research, and, finally, it will also describe the use of IRT models in a variety of settings, e.g. computer adaptive testing, measurement bias studies, and test equating studies.
