Abstract

The contribution provides ordinal item response models to investigate heterogeneity in attitudes. In contrast to standard models, the approach accounts for covariate effects in studying two essential components of attitudes: direction and strength. An application to the evaluation of presidential candidate traits exemplifies the types of substantive insights that can be gained.
