Webb22 feb. 2024 · To overcome these problems, a new scoring method for FC items has recently been introduced: Thurstonian item response theory (T-IRT) models ( ). In contrast to traditional scoring methods for FC items, estimates obtained from T-IRT models are designed to be non-ipsative and therefore to allow for comparisons between individuals. WebbThe Thurstonian IRT model is a multidimensional item response model with some special features that can be straightforwardly estimated using the general modeling software Mplus (Muthén & Muthén, 1998-2010), which also conveniently estimates trait scores for individuals.
