The Academic Medical Center Linear Disability Score (ALDS) item bank: item response theory analysis in a mixed patient population [PDF]
Health and Quality of Life Outcomes, 2005 Background Currently, there is a lot of interest in the flexible framework offered by item banks for measuring patient relevant outcomes. However, there are few item banks, which have been developed to quantify functional status, as expressed by the ...

A Comparative Study of Item Response Theory Models for Mixed Discrete-Continuous Responses [PDF]
Journal of IntelligenceLanguage proficiency assessments are pivotal in educational and professional decision-making. With the integration of AI-driven technologies, these assessments can more frequently use item types, such as dictation tasks, producing response features with ...

Classification accuracy of mixed format tests: A bi-factor approach [PDF]
Frontiers in Psychology, 2016 Mixed format tests (e.g., a test consisting of multiple-choice [MC] items and constructed response [CR] items) have become increasingly popular. However, the latent structure of item pools consisting of the two formats is still equivocal.

Efficiency Analysis of Item Response Theory Kernel Equating for Mixed-Format Tests [PDF]
Applied Psychological Measurement, 2023 This study aims to evaluate the performance of Item Response Theory (IRT) kernel equating in the context of mixed-format tests by comparing it to IRT observed score equating and kernel equating with log-linear presmoothing. Comparisons were made through both simulations and real data applications, under both equivalent groups (EG) and non-equivalent ...

Item Response Theory Models for Wording Effects in Mixed-Format Scales [PDF]
Educational and Psychological Measurement, 2014 Many scales contain both positively and negatively worded items. Reverse recoding of negatively worded items might not be enough for them to function as positively worded items do. In this study, we commented on the drawbacks of existing approaches to wording effect in mixed-format scales and used bi-factor item response theory (IRT) models to test ...

Rheumatoid arthritis, item response theory, Blom transformation, and mixed models [PDF]
BMC Proceedings, 2007 We studied rheumatoid arthritis (RA) in the North American Rheumatoid Arthritis Consortium (NARAC) data (1499 subjects; 757 families). Identical methods were applied for studying RA in the Genetic Analysis Workshop 15 (GAW15) simulated data (with a prior knowledge of the simulation answers).

A-08 Examination of Three Functional Living Scales Using Item Response Theory Modeling in a Mixed Sample [PDF]
Archives of Clinical Neuropsychology, 2020 Abstract Objective Characterize three functional living scales under item response theory and examine these scales for evidence of differential item functioning (DIF) by participant and/or informant ethnicity and education.

Materials of International Practical Internet Conference “Challenges of Science”, 2023 Basic knowledge of mathematics is essential for solving problems contextually. Mathematics has a function for the development of the ability to calculate, measure, find, and use mathematical formulas that can provide students with an understanding of concepts related to life phenomena.

Use of Mixed Item Response Theory in Rating Scales
lnternational Electronic Journal of Elementary Education, 2019 This study aimed to compare the Graded Response Model (GRM) and the Mixed-Graded Response Model (MixGRM) in terms of model data-fit and parameters and demonstrate the application of MixGRM on real data. In this context, this study is basic research based on the International Computer and Information Literacy Study in 2013 conducted with eighth-grade ...

Practical Consequences of Item Response Theory Model Misfit in the Context of Test Equating with Mixed-Format Test Data [PDF]
Frontiers in Psychology, 2017 In item response theory (IRT) models, assessing model-data fit is an essential step in IRT calibration. While no general agreement has ever been reached on the best methods or approaches to use for detecting misfit, perhaps the more important comment based upon the research findings is that rarely does the research evaluate IRT misfit by focusing on ...
