Arthritis Care &Research, EarlyView.Systemic sclerosis (SSc) is a rare autoimmune disease defined by immune dysregulation, vasculopathy, and progressive fibrosis of the skin and internal organs. Despite advances in care, major complications such as interstitial lung disease (ILD) and myocardial involvement remain the leading causes of morbidity and mortality.

Evaluating Stan’s Variational Bayes Algorithm for Estimating Multidimensional IRT Models
Psych, 2022 Bayesian estimation of multidimensional item response theory (IRT) models in large data sets may come with impractical computational burdens when general-purpose Markov chain Monte Carlo (MCMC) samplers are employed.

A multilevel multidimensional finite mixture item response model to cluster respondents and countries: the forms of self-criticising/attacking and self-reassuring scale [PDF]
, 2020 The aim of this study was to test the multilevel multidimensional finite mixture item response model of the Forms of Self-Criticising/Attacking and Self-Reassuring Scale (FSCRS) to cluster respondents and countries from 13 samples (N = 7,714) and from 12

Arthritis Care &Research, EarlyView.Objective The aim of this study was to test the hypothesis that multijoint osteoarthritis would modify the relation between time and frailty progression, in which more affected joints would lead to larger declines over six years compared to those without osteoarthritis using data from the Canadian Longitudinal Study on Aging.

Scoring and estimating score precision using multidimensional IRT [PDF]
, 2015 The ultimate goal of measurement is to produce a score by which individuals can be assessed and differentiated. Item response theory (IRT) modeling views responses to test items as indicators of a respondent’s standing on some underlying psychological ...

Influence of Context on Item Parameters in Forced-Choice Personality Assessments [PDF]
, 2016 A fundamental assumption in computerized adaptive testing (CAT) is that item parameters are invariant with respect to context – items surrounding the administered item.

Arthritis Care &Research, EarlyView.Objective This study investigated the association between frailty and cancer incidence and mortality in patients with rheumatoid arthritis (RA). It aimed to identify how frailty influences cancer risk and cancer‐specific outcomes. Methods This retrospective cohort study analyzed data from the Veterans’ Affairs Rheumatoid Arthritis Registry (2002–2023).

Variable Speed Across Dimensions of Ability in the Joint Model for Responses and Response Times
Frontiers in Psychology, 2021 Working speed as a latent variable reflects a respondent’s efficiency to apply a specific skill, or a piece of knowledge to solve a problem. In this study, the common assumption of many response time models is relaxed in which respondents work with a ...

Item Response Theory Models for Ipsative Tests With Multidimensional Pairwise Comparison Items [PDF]
Applied Psychological Measurement, 2017 There is re-emerging interest in adopting forced-choice items to address the issue of response bias in Likert-type items for noncognitive latent traits. Multidimensional pairwise comparison (MPC) items are commonly used forced-choice items. However, few studies have been aimed at developing item response theory models for MPC items owing to the ...

A dual process item response theory model for polytomous multidimensional forced‐choice items
British Journal of Mathematical and Statistical Psychology, 2023 Abstract The use of multidimensional forced‐choice (MFC) items to assess non‐cognitive traits such as personality, interests and values in psychological tests has a long history, because MFC items show strengths in preventing response bias.
