Abstract
The present chapter elaborates on the use of ordered latent class models (OR-LCMs) in analyzing ordinal measurement properties of psychological tests and questionnaires in the context of clinical and medical psychology. Using simulated data, we illustrate several approaches for evaluating absolute fit of the model and we show how the fitted OR-LCMs can be used to gain insight into the reliability and the measurement precision of total scores for ranking and classifying individuals into ordered classes.
