Reeves, Todd D.; Onder, Yasemin; Kraner, Chris – Educational Assessment, Evaluation and Accountability, 2023
As beliefs are well-known antecedents of teachers' practices, including assessment practices, sound measurement of teacher beliefs is critical for scholarly research as well as practical purposes. The present study examined the validity of inferences derived from the Conceptions of Assessment III--Abridged (COA-IIIA) instrument with US PK-12…

Domingue, Benjamin W.; Trejo, Sam; Armstrong-Carter, Emma; Tucker-Drob, Elliot M. – Grantee Submission, 2020
Interest in the study of gene-environment interaction has recently grown due to the sudden availability of molecular genetic data--in particular, polygenic scores--in many long-running longitudinal studies. Identifying and estimating statistical interactions comes with several analytic and inferential challenges; these challenges are heightened…

Nicewander, W. Alan – Educational and Psychological Measurement, 2019
This inquiry is focused on three indicators of the precision of measurement--conditional on fixed values of ?, the latent variable of item response theory (IRT). The indicators that are compared are (1) The traditional, conditional standard errors, s(eX|?) = CSEM; (2) the IRT-based conditional standard errors, s[subscript irt](eX|?)=C[subscript…

Wang, Huan; Kim, Dong-In – Online Submission, 2022
A fundamental premise in assessment is that the underlying construct is equivalent across different groups of students and that this structure does not vary over years. The pandemic has potentially impacted opportunity to learn and disrupted the internal structure of assessments in various ways. Past research has suggested that students tended to…

DeMars, Christine – Applied Measurement in Education, 2015
In generalizability theory studies in large-scale testing contexts, sometimes a facet is very sparsely crossed with the object of measurement. For example, when assessments are scored by human raters, it may not be practical to have every rater score all students. Sometimes the scoring is systematically designed such that the raters are…

Kelcey, Ben; Wang, Shanshan; Cox, Kyle – Society for Research on Educational Effectiveness, 2016
Valid and reliable measurement of unobserved latent variables is essential to understanding and improving education. A common and persistent approach to assessing latent constructs in education is the use of rater inferential judgment. The purpose of this study is to develop high-dimensional explanatory random item effects models designed for…

Chen, Chia-ling; Shen, I-hsuan; Chen, Chung-yao; Wu, Ching-yi; Liu, Wen-Yu; Chung, Chia-ying – Research in Developmental Disabilities: A Multidisciplinary Journal, 2013
This study examined criterion-related validity and clinimetric properties of the pediatric balance scale ("PBS") in children with cerebral palsy (CP). Forty-five children with CP (age range: 19-77 months) and their parents participated in this study. At baseline and at follow up, Pearson correlation coefficients were used to determine…

Petscher, Yaacov; Cummings, Kelli Dawn; Biancarosa, Gina; Fien, Hank – Assessment for Effective Intervention, 2013
The purpose of this article is to provide a commentary on the current state of several measurement issues pertaining to curriculum-based measures of reading (R-CBM). We begin by providing an overview of the utility of R-CBM, followed by a presentation of five specific measurements considerations: (a) the reliability of R-CBM oral reading fluency…

Moses, Tim – ETS Research Report Series, 2013
The purpose of this report is to review ETS psychometric contributions that focus on test scores. Two major sections review contributions based on assessing test scores' measurement characteristics and other contributions about using test scores as predictors in correlational and regression relationships. An additional section reviews additional…

Ip, Edward Hak-Sing; Chen, Shyh-Huei – Applied Psychological Measurement, 2012
The problem of fitting unidimensional item-response models to potentially multidimensional data has been extensively studied. The focus of this article is on response data that contains a major dimension of interest but that may also contain minor nuisance dimensions. Because fitting a unidimensional model to multidimensional data results in…

Steiner, Peter M.; Cook, Thomas D.; Shadish, William R. – Journal of Educational and Behavioral Statistics, 2011
The effect of unreliability of measurement on propensity score (PS) adjusted treatment effects has not been previously studied. The authors report on a study simulating different degrees of unreliability in the multiple covariates that were used to estimate the PS. The simulation uses the same data as two prior studies. Shadish, Clark, and Steiner…

Kruyen, Peter M.; Emons, Wilco H. M.; Sijtsma, Klaas – International Journal of Testing, 2012
Personnel selection shows an enduring need for short stand-alone tests consisting of, say, 5 to 15 items. Despite their efficiency, short tests are more vulnerable to measurement error than longer test versions. Consequently, the question arises to what extent reducing test length deteriorates decision quality due to increased impact of…

Lucas, Richard E.; Donnellan, M. Brent – Social Indicators Research, 2012
Life satisfaction is often assessed using single-item measures. However, estimating the reliability of these measures can be difficult because internal consistency coefficients cannot be calculated. Existing approaches use longitudinal data to isolate occasion-specific variance from variance that is either completely stable or variance that…

Liaw, Lih-Jiun; Hsieh, Ching-Lin; Hsu, Miao-Ju; Chen, Hui-Mei; Lin, Jau-Hong; Lo, Sing-Kai – International Journal of Rehabilitation Research, 2012
The aim of this study is to determine the test-retest reproducibility of the seven-item Short-Form Berg Balance Scale (SFBBS) and the five-item Short-Form Postural Assessment Scale for Stroke Patients (SFPASS) in individuals with chronic stroke. Fifty-two chronic stroke patients from two rehabilitation departments were included in the study. Both…

Shang, Yi – Journal of Educational Measurement, 2012
Growth models are used extensively in the context of educational accountability to evaluate student-, class-, and school-level growth. However, when error-prone test scores are used as independent variables or right-hand-side controls, the estimation of such growth models can be substantially biased. This article introduces a…
