A reusable Bayesian IRT workflow for instrument validation: A tutorial with a small-sample case study in teacher belief measurement

2026-04-13

Abstract excerpt

<p>Bayesian Item Response Theory (IRT) offers distinct advantages for fitting complex measurement models under sample-size constraints, yet practical guidance on implementing complete Bayesian IRT workflows for applied researchers remains limited. This tutorial presents a reusable workflow for validating multidimensional instruments with limited samples using the R package brms. The workflow guides researchers thr...
