Sample Size Requirements for Estimation of Item Parameters in the Multidimensional Graded Response Model [PDF]
Frontiers in Psychology, 2016 Likert types of rating scales in which a respondent chooses a response from an ordered set of response options are used to measure a wide variety of psychological, educational, and medical outcome variables.

Re-assessing the Psychometric Properties of Stress Appraisal Measure in Ghana Using Multidimensional Graded Response Model [PDF]
Frontiers in Psychology, 2022 Despite the widespread use of the stress appraisal measure questionnaire in sport psychology literature, information on the psychometric properties of this survey instrument across different cultures and samples is still lacking.

Performance of the S - χ 2 Statistic for the Multidimensional Graded Response Model. [PDF]
Educ Psychol Meas, 2021 [Formula: see text] is a popular item fit index that is available in commercial software packages such as flexMIRT. However, no research has systematically examined the performance of [Formula: see text] for detecting item misfit within the context of the multidimensional graded response model (MGRM).

Bayesian Estimation of a Multidimensional Additive Graded Response Model for Correlated Traits [PDF]
Communications in Statistics - Simulation and Computation, 2014 The aim of the article is to propose a Bayesian estimation through Markov chain Monte Carlo of a multidimensional item response theory model for graded responses with an additive structure with correlated latent traits. A simulation study is conducted to evaluate the model parameter recovery under different conditions (sample size, test and subtest ...

Assessment of health surveys: fitting a multidimensional graded response model [PDF]
Psychology, Health & Medicine, 2018 The multidimensional graded response model, an item response theory (IRT) model, can be used to improve the assessment of surveys, even when sample sizes are restricted. Typically, health-based survey development utilizes classical statistical techniques (e.g. reliability and factor analysis).

A Multidimensional Item Response Theory Model for Continuous and Graded Responses With Error in Persons and Items [PDF]
Educational and Psychological Measurement, 2021 Item response theory “dual” models (DMs) in which both items and individuals are viewed as sources of differential measurement error so far have been proposed only for unidimensional measures. This article proposes two multidimensional extensions of existing DMs: the M-DTCRM (dual Thurstonian continuous response model), intended for (approximately ...

Confirmatory Multidimensional IRT Unfolding Models for Graded-Response Items [PDF]
Applied Psychological Measurement, 2015 Most unfolding item response models for graded-response items are unidimensional. When there are multiple tests of graded-response items, unidimensional unfolding models become inefficient. To resolve this problem, the authors developed the confirmatory multidimensional generalized graded unfolding model, which is a multidimensional extension of the ...
