Using Item Response Theory Models in Scaling Severity Scores in Alcohol Research-A Tutorial. [PDF]

Drug Alcohol Rev
ABSTRACT Introduction Questionnaires are frequently used in the assessment of drug and alcohol dependence. Methods Typically, sum scores are used for aggregation, which come with several underlying assumptions. If untested psychometrically, the reliability and sufficiency of a sum score as a measure of the characteristic of interest remain unclear.

Psychometric Evaluation of the Patient-Experienced Continuity of Care Questionnaire (PECQ) Using Rasch Model. [PDF]

Health Expect
ABSTRACT Background The Patient‐Experienced Continuity of care Questionnaire (PECQ) was developed to measure continuity of care (CoC) in primary care, but has only been evaluated in accordance with classical test theory, which has some weaknesses compared with modern test theory.

Fears Related to Blood-Injection-Injury Inhibit Bystanders from Giving First Aid [PDF]

Western Journal of Emergency Medicine
Introduction: Prehospital emergency care is vital for saving lives, and increasing bystander involvement can improve survival and recovery. One potential barrier to providing first aid is blood-injury injection (BII) phobia, which affects up to 20% of ...

Tree-Based Global Model Tests for Polytomous Rasch Models [PDF]

Educational and Psychological Measurement, 2016
Psychometric measurement models are only valid if measurement invariance holds between test takers of different groups. Global model tests, such as the well-established likelihood ratio (LR) test, are sensitive to violations of measurement invariance, such as differential item functioning and differential step functioning.

Method of successive dichotomizations: An improved method for estimating measures of latent variables from rating scale data. [PDF]

PLoS ONE, 2018
The most commonly used models for estimating measures of latent variables from polytomous rating scale data are the Andrich rating scale model and the Samejima graded response model. The Andrich model has the undesirable property of estimating disordered

Application of the Rasch measurement model in rehabilitation research and practice: early developments, current practice, and future challenges

Frontiers in Rehabilitation Sciences, 2023
The application of the Rasch measurement model in rehabilitation is now well established. Both its dichotomous and polytomous forms provide for transforming ordinal scales into interval-level measures, consistent with the requirements of fundamental ...

Inferences of associated latent variables by the observable test scores. [PDF]

Br J Math Stat Psychol
Abstract Test scores, like the sum score, can be useful for making inferences about the latent variables. The conditions under which such test scores allow for inferences of the latent variables based on a “weaker” stochastic ordering are generalized to any monotone latent variable model for which the latent variables are associated.

Detecting Differential Item and Step Functioning with Rating Scale and Partial Credit Trees [PDF]

, 2014
Several statistical procedures have been suggested for detecting differential item functioning (DIF) and differential step functioning (DSF) in polytomous items.

Cognitive Ability-Demand Gap Analysis With Latent Response Models

IEEE Access, 2014
A better understanding of human cognitive ability-demand gap (ADG) is critical in designing assistive technology solution that is accurate and adaptive over a wide range of human-agent interaction.

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
