A family of measures to evaluate scale reliability in a longitudinal setting Universiteit Hasselt KU Leuven
The concept of reliability denotes one of the most important psychometric properties of a measurement scale. Reliability refers to the capacity of the scale to discriminate between subjects in a given population. In classical test theory, it is often estimated by using the intraclass correlation coefficient based on two replicate measurements. However, the modelling framework that is used in this theory is often too narrow when applied in ...
Harmonization process and reliability assessment of anthropometric measurements in a multicenter study in adolescents Universiteit Gent
The Healthy Lifestyle in Europe by Nutrition in Adolescence Study aims to describe total body fat percentage andanthropometric indices of body fat distribution in European adolescents.Objective: To describe the standardization process and reliability of anthropometric and bioelectrical impedance analysis (BIA) measurements. We examined both intra- and interobserver errors for skinfolds, circumferences and BIA.Methods: For the intraobserver error ...

Test-retest reliability in metric conjoint experiments : a new workflow to evaluate confidence in model results Universiteit Gent
Metric conjoint studies are a popular research design in the entrepreneurship domain. For these studies, test-retest reliabilities of ρ > .70 or higher are an often-cited reliability criterion. Despite their widespread use, however, there is little rigorous analysis of whether test-retest reliability in metric conjoint studies relates to model efficacy. Informed by a systematic literature review, we conducted two Monte Carlo simulations to ...
Absolute and Relative Reliability of a Comprehensive Quantitative Sensory Testing Protocol in Women Treated for Breast Cancer KU Leuven Universiteit Antwerpen
OBJECTIVE: Quantitative sensory testing (QST) consists of noninvasive psychophysical assessment techniques to evaluate the functioning of the somatosensory nervous system. Despite the importance of reliability for the correct use of QST results in research and clinical practice, the relative and absolute intra- and inter-rater reliability of a comprehensive QST protocol to evaluate the functioning of both the peripheral and central somatosensory ...
Reliability of base-isolated structures with sliding hydromagnetic bearings considering stochastic ground motions Universiteit Gent
Stochastic seismic response analysis and reliability assessment of a base-isolated structure with sliding hydro-magnetic bearings are performed combining the probability density evolution method and the stochastic func-tion model of seismic ground motions. The reliability assessments are based on the extreme value distribution of the inter-story drifts of the base-isolated structure. Compared with the responses of the base-fixed struc-ture, the ...
A multi-dimensional analysis of reliability criteria : from deterministic NU+2212 1 to a probabilistic approach Universiteit Gent KU Leuven
A Unified Approach to Multi-item Reliability Universiteit Hasselt KU Leuven
P>The reliability of multi-item scales has received a lot of attention in the psychometric literature, where a myriad of measures like the Cronbach's alpha or the Spearman-Brown formula have been proposed. Most of these measures, however, are based on very restrictive models that apply only to unidimensional instruments. In this article, we introduce two measures to quantify the reliability of multi-item scales based on a more general model. ...
Insights into the reliability of Ni/Cu plated p-PERC silicon solar cells Universiteit Hasselt KU Leuven Universiteit Gent
Selective laser ablation of dielectric layers in combination with plated Ni/Cu/Ag contacts have been investigated by many photovoltaic researchers. Despite that there has been quite some practical progress on improved processing, the reliability of plated Ni/Cu/Ag cells still needs further insight and understanding. In this paper, the impact of laser induced defects that result from a ps-laser (wavelength 355nm) ablation on the performance of ...
