  • Bias and precision in true‐score estimation

    Open Access•L Andries Van Der Ark, Wilco H M Emons et al.•ARTICLE•British Journal of Mathematical…•2026

    We discuss two approaches to estimating the true score from classical test theory, each with a corresponding measure of uncertainty due to measurement error: the classical method with the standard error of measurement (SEM) and Kelley's method with the standard error of estimation (SEE). For both approaches, we examined the bias and sampling variability of the true‐score, SEM and SEE estimators, as these properties were largely unknown. For each …

  • Exploring the multimedia effect in testing: The role of coherence and item-level analysis

    Open Access•Jorik Arts, Wilco H M Emons et al.•ARTICLE•Frontiers in Education•2024

    Educational tests often combine text and images in items. Research shows that including images in test items can influence response accuracy, termed the Multimedia Effect in Testing. This effect suggests that using pictures in tests can enhance student performance and reduce the perception of item difficulty. As such, the Multimedia Effect in Testing could influence test validity. However, research in this area has produced varied and conflicting…

  • Assessing the temporal stability of psychological constructs: An illustration of Type D personality, anxiety and depression

    Open Access•Paul Lodder, Nina Kupper et al.•ARTICLE•Journal of Research in Personality•2022•References: 80

    Various methods exist to assess the temporal stability of psychological constructs. In this paper we discuss common methods based on a review of the personality traits negative affectivity and social inhibition. Most methods ignore the non-normal distributions and measurement error in the questionnaire item scores. We illustrate how to handle these issues using three longitudinal latent variable models. We further highlight the importance of test…

  • Latent Logistic Interaction Modeling: A Simulation and Empirical Illustration of Type D Personality

    Open Access•Paul Lodder, Wilco H M Emons et al.•ARTICLE•Structural Equation Modeling: A…•2021

    This study focuses on three popular methods to model interactions between two constructs containing measurement error in predicting an observed binary outcome: logistic regression using (1) observed scores, (2) factor scores, and (3) Structural Equation Modeling (SEM). It is still unclear how they compare with respect to bias and precision in the estimated interaction when item scores underlying the interaction constructs are skewed and ordinal. …

  • A cross-cultural comparison of non-cognitive outputs towards science between Turkish and Dutch students taking into account detected person misfit

  • Self-esteem and satisfaction with social relationships across time

    Elisabeth L De Moor, Jaap J A Denissen et al.•ARTICLE•Journal of Personality and Social…•2021•Cited by: 5

    14,741). When using CT-SEM, we found a bidirectional positive relation between self-esteem and satisfaction with social relationships, with larger effects over longer intervals. When using RI-CT-SEM, we found the largest effects of self-esteem and satisfaction with social relationships across intervals of 1 year, with smaller effect sizes at both shorter and longer intervals. In addition, the effect of fluctuations in people's satisfaction with s…

  • Modeling Interactions Between Latent Variables in Research on Type D Personality: A Monte Carlo Simulation and Clinical Study of Depression and Anxiety

    Open Access•Paul Lodder, Johan Denollet et al.•ARTICLE•Multivariate Behavioral Research•2019

    Several approaches exist to model interactions between latent variables. However, it is unclear how these perform when item scores are skewed and ordinal. Research on Type D personality serves as a good case study for that matter. In Study 1, we fitted a multivariate interaction model to predict depression and anxiety with Type D personality, operationalized as an interaction between its two subcomponents negative affectivity (NA) and social inhi…

  • Prevalence of anxiety in patients with an implantable cardioverter defibrillator: Measurement equivalence of the Hads-A and the STAI-S

    Open Access•Wilco H M Emons, W H Emons et al.•ARTICLE•Quality of Life Research•2019

    STAI-S and HADS-A reflect a common anxiety attribute, but using the recommended cutoff scores on the respective measures show very different prevalence rates and would classify patients as anxious with the STAI-S who would not be identified as such with the HADS-A. Clinicians and researchers should be aware of the inequivalence when using these measures for screening and determining the prevalence of probable clinical anxiety levels

  • Psychometric Properties of the Bermond–Vorst Alexithymia Questionnaire (BVAQ) in the General Population and a Clinical Population

    Open Access•Lars de Vroege, Wilco H M Emons et al.•ARTICLE•Frontiers in Psychiatry•2018

    The BVAQ is a reliable alternative measure for measuring alexithymia

  • Alexithymia Has No Clinically Relevant Association With Outcome of Multimodal Treatment Tailored to Needs of Patients Suffering From Somatic Symptom and Related Disorders. A Clinical Prospective Study

    Open Access•Lars de Vroege, Wilco H M Emons et al.•ARTICLE•Frontiers in Psychiatry•2018

    Introduction: Alexithymia may moderate the effectiveness of treatment and may predict impaired general functioning of patients suffering from somatic symptom and related disorders (SSRD). Aim: We compared alexithymia levels in a clinical prospective study with 234 consecutive patients suffering from SSRD from the Centre of Excellence for Body, Mind, and Health, Tilburg using the Bermond-Vorst Alexithymia Questionnaire, with general population nor…

  • Longitudinal measurement invariance of the Dutch Outcome Questionnaire-45 in a clinical sample

    Open Access•Ruslan Jabrayilov, Wilco H M Emons et al.•ARTICLE•Quality of Life Research•2017

    Even though for two items the assumption of invariance was violated, results suggest that the effects of these violations on practical change assessment using the OQ-45 were negligible

  • Separating models, ideas, and data to avoid a paradox: Rejoinder to Humphry

    Open Access•Klaas Sijtsma, Wilco H M Emons•ARTICLE•Theory & Psychology•2013

    This article is a rejoinder to Humphry’s (2013) comment on Sijtsma (2012). Sijtsma argued that the Rasch paradox does not exist but Humphry replies that the Rasch paradox can occur provided the measurement procedure is precise enough. The rejoinder argues that the debates about the Rasch paradox mingle properties of formal psychometric models, ideas about what people do when they respond to the items in a test, and the kind of data they produce. …

  • Explanatory, Multilevel Person-Fit Analysis of Response Consistency on the Spielberger State-Trait Anxiety Inventory

    Judith M Conijn, Wilco H M Emons et al.•ARTICLE•Multivariate Behavioral Research•2013

    Self-report measures are vulnerable to concentration and motivation problems, leading to responses that may be inconsistent with the respondent's latent trait value. We investigated response consistency in a sample (N = 860) of cardiac patients with an implantable cardioverter defibrillator and their partners who completed the Spielberger State-Trait Anxiety Inventory on five measurement occasions. For each occasion and for both the state and tra…

  • On the Usefulness of a Multilevel Logistic Regression Approach to Person-Fit Analysis

    Judith M Conijn, Wilco H M Emons et al.•ARTICLE•Multivariate Behavioral Research•2011

    The logistic person response function (PRF) models the probability of a correct response as a function of the item locations. Reise (2000) proposed to use the slope parameter of the logistic PRF as a person-fit measure. He reformulated the logistic PRF model as a multilevel logistic regression model and estimated the PRF parameters from this multilevel framework. An advantage of the multilevel framework is that it allows relating person fit to ex…

  • Nonparametric IRT analysis of Quality-of-Life Scales and its application to the World Health Organization Quality-of-Life Scale (WHOQOL-Bref)

    Open Access•Klaas Sijtsma, Wilco H M Emons et al.•ARTICLE•Quality of Life Research•2008

    The nonparametric monotone homogeneity model is highly suited for data analysis in a health-related quality-of-life context, and the parametric graded response model may add interesting features to measurement provided the model fits the data well

  • Testing Hypotheses About the Person-Response Function in Person-Fit Analysis

    Wilco H M Emons, Klaas Sijtsma et al.•ARTICLE•Multivariate Behavioral Research•2004

    The person-response function (PRF) relates the probability of an individual's correct answer to the difficulty of items measuring the same latent trait. Local deviations of the observed PRF from the expected PRF indicate person misfit. We discuss two new approaches to investigate person fit. The first approach uses kernel smoothing to estimate continuous PRF estimates. Graphical displays of PRFs were used to localize and diagnose misfit. The seco…
