Using Item Response Theory Models in Scaling Severity Scores in Alcohol Research—A Tutorial
We introduce these concepts with the help of real data from the Danish alcohol and drug consumption survey from 2011, using items on alcohol harms to others. The data and the full reproducible code in STATA and R are provided. Reporting guidelines are given as well as a discussion of pitfalls and limitations.
