Item Response Modeling of Forced-Choice Questionnaires [PDF]

, 2011
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 ...

Forecasting forecaster accuracy: Contributions of past performance and individual differences

Judgment and Decision Making, 2021
A growing body of research indicates that forecasting skill is a unique and stable trait: forecasters with a track record of high accuracy tend to maintain this record. But how does one identify skilled forecasters effectively?

Nonignorable Consequences of (Partially) Ignoring Missing Item Responses: Students Omit (Constructed Response) Items Due to a Lack of Knowledge

Knowledge, 2023
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 ...

Item Response Models for Forced-Choice Questionnaires: A Common Framework [PDF]

, 2016
In forced-choice questionnaires, respondents have to make choices between two or more items presented at the same time. Several IRT models have been developed to link respondent choices to underlying psychological attributes, including the recent MUPP ...

The Value of Response Times in Item Response Modeling [PDF]

Measurement: Interdisciplinary Research and Perspectives, 2015
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.

A Penalty Approach to Differential Item Functioning in Rasch Models [PDF]

, 2012
A new diagnostic tool for the identification of differential item functioning (DIF) is proposed. Classical approaches to DIF allow to consider only few subpopulations like ethnic groups when investigating if the solution of items depends on the ...

Understanding examinees’ item responses through cognitive modeling of response accuracy and response times

Large-scale Assessments in Education, 2023
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.

Investigating the Impact of Item Parameter Drift for Item Response Theory Models with Mixture Distributions

Frontiers in Psychology, 2016
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]

British Journal of Mathematical and Statistical Psychology, 2011
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.
