Item response theory is usually applied to items with a selected-response format, such as multiple choice items, whereas generalizability theory is usually applied to constructed-response tasks assessed by raters. However, in many situations, raters may use rating scales consisting of items with a selected-response format. This chapter presents a short overview of how item response theory and g...

of the Dissertation Generalizability in Causal Inference: Theory and Algorithms

In recent years, researchers have described how to analyze generalizability theory (GT) based univariate, multivariate, and bifactor designs using structural equation models. However, within GT studies of models, variance components been limited those reflecting relative differences in scores for norm-referencing purposes, with only guidance provided estimating key indices when making changes m...
