Item Response Modeling of Forced-Choice Questionnaires [PDF]
Multidimensional forced-choice formats can significantly reduce the impact of numerous response biases typically associated with rating scales. However, if scored with classical methodology, these questionnaires produce ipsative data, which lead to ...

A Monte Carlo study of IRTree models’ ability to recover item parameters
Item response tree (IRTree) models are theorized to extract response styles from self-report data by utilizing multidimensional item response theory (IRT) models based on theoretical decision processes.

The Effectiveness of the Adaptive Testing Using Selected Response Items and Constructed Response Items [PDF]
This study aimed at investigate the effectiveness of the adaptive testing which consists of both dichotomous selected response items and polytomous items by using generated data from computer,60 dichotomous responses and 10 polytomous responses were ...

In recent literature, alternative models for handling missing item responses in large-scale assessments have been proposed. Based on simulations and arguments based on psychometric test theory, it is argued in this literature that missing item responses ...

The Value of Response Times in Item Response Modeling [PDF]
A new and very interesting approach to the analysis of responses and response times is proposed by Goldhammer (this issue). In this approach, differences in the speed-ability compromise within respondents are considered to confound the differences in ability between respondents.

Statistical models for the relations between variables encompass assumptions about the underlying mechanism that generated the relations in the observed data. This dissertation introduces item response mechanics as the study of data-generating mechanisms

Understanding the cognitive processes, skills and strategies that examinees use in testing is important for construct validity and score interpretability. Although response processes evidence has long been included as an important aspect of validity (i.e.

This study investigates the impact of item parameter drift (IPD) on parameter and ability estimation when the underlying measurement model fits a mixture distribution, thereby violating the item invariance property of unidimensional item response theory (

Logistic response models with item interactions [PDF]
Items that are clustered according to shared content may violate the principle of conditional independence commonly used in item response theory. This paper investigates the capabilities of a logistic item response model in relation to locally dependent item responses.

ABSTRACT Background Loneliness is associated with adverse physical and mental health outcomes and remains understudied in children and adolescents undergoing cancer therapy. Pediatric oncology patients may be at increased risk due to medical isolation and disruption of social networks.
