Sufficient and Necessary Conditions for the Identifiability of DINA Models with Polytomous Responses [PDF]

Psychometrika 89 (2024) 717-740, 2023
Cognitive Diagnosis Models (CDMs) provide a powerful statistical and psychometric tool for researchers and practitioners to learn fine-grained diagnostic information about respondents' latent attributes. There has been a growing interest in the use of CDMs for polytomous response data, as more and more items with multiple response options become widely

Regularized Bayesian calibration and scoring of the WD-FAB IRT model improves predictive performance over marginal maximum likelihood [PDF]

PLoS ONE 17(4): e0266350 (2022), 2020
Item response theory (IRT) is the statistical paradigm underlying a dominant family of generative probabilistic models for test responses, used to quantify traits in individuals relative to target populations. The graded response model (GRM) is a particular IRT model that is used for ordered polytomous test responses.

A rare disease patient-reported outcome measure: revision and validation of the German version of the Systemic Sclerosis Quality of Life Questionnaire (SScQoL) using the Rasch model

Orphanet Journal of Rare Diseases, 2021
Background Rare disease patient-reported outcome measures (PROMs) require linguistic adaptation to overcome the challenge of geographically dispersed patient populations. Importantly, PROMs such as health-related quality of life (HRQoL) should accurately

Judging similarity versus judging difference

Frontiers in Education, 2023
A key feature of the polytomous Rasch model is that it entails a single classification process into one of a set of ordered response categories. The first aim of this article is to make explicit two processes in rubric designs that bring about such ...

An alternative application of Rasch analysis to assess data from ophthalmic patient-reported outcome instruments.

PLoS ONE, 2018
PurposeTo highlight the potential shortcomings associated with the current use Rasch analysis for validation of ophthalmic questionnaires, and to present an alternative application of Rasch analysis to derive insights specific to the cohort of patients ...

The assessment of procedural skills in physiotherapy education: a measurement study using the Rasch model

Archives of Physiotherapy, 2020
Background Procedural skills are a key element in the training of future physiotherapists. Procedural skills relate to the acquisition of appropriate motor skills, which allow the safe application of clinical procedures to patients.

Invariance of Comparisons: Separation of Item and Person Parameters beyond Rasch Models [PDF]

arXiv, 2023
The Rasch model is the most prominent member of the class of latent trait models that are in common use. The main reason is that it can be considered as a measurement model that allows to separate person and item parameters, a feature that is referred to as invariance of comparisons or specific objectivity.

D-Optimal Design for the Rasch Counts Model with Multiple Binary Predictors [PDF]

British Journal of Mathematical and Statistical Psychology Volume 73, 2020, Issue 3, p. 541-555, 2018
In this paper, we derive optimal designs for the Rasch Poisson counts model and the Rasch Poisson-Gamma counts model incorporating several binary predictors for the difficulty parameter. To efficiently estimate the regression coefficients of the predictors, locally D-optimal designs are developed. After an introduction to the Rasch Poisson counts model

A Rasch Re-Analysis of the Partnership Questionnaire

SAGE Open, 2015
The Partnership Questionnaire (PFB) is used favorably in the German language area to measure partnership quality. The goal of the present study is to re-analyze the subscales of the PFB ( Conflict Behavior, Tenderness, Communication ) via the Rasch model.
