Item Parameter Calibration in the Multidimensional Graded Response Model with High Dimensional Tests
, 2023 Multidimensional item response models, such as the multidimensional graded response model (MGRM), are becoming increasingly common in educational and psychological research in part due to the associated advantages of multidimensional computerized adaptive testing. These methods, however, require known or calibrated item parameters. Existing research on

Applied Psychological MeasurementDifferential item functioning (DIF) is a common challenge when examining latent traits in large scale surveys. In recent work, methods from the field of machine learning such as model-based recursive partitioning have been proposed to identify subgroups with DIF when little theoretical guidance and many potential subgroups are available. On this basis,

Item Response Modeling of Forced-Choice Questionnaires [PDF]
, 2011 Multidimensional forced-choice formats can significantly reduce the impact of numerous response biases typically associated with rating scales. However, if scored with classical methodology, these questionnaires produce ipsative data, which lead to ...

Frontiers in Human Neuroscience, 2021 Empathy is often split into an affective facet for embodied simulation or sometimes sensorial processing, and a cognitive facet for mentalizing and perspective-taking. However, a recent neurophenomenological framework proposes a graded view on empathy (i.
