Cao, Chunhua; Kim, Eun Sook; Chen, Yi-Hsin; Ferron, John; Stark, Stephen – Educational and Psychological Measurement, 2019
In multilevel multiple-indicator multiple-cause (MIMIC) models, covariates can interact at the within level, at the between level, or across levels. This study examines the performance of multilevel MIMIC models in estimating and detecting the interaction effect of two covariates through a simulation and provides an empirical demonstration of…

Attali, Yigal; Laitusis, Cara; Stone, Elizabeth – Educational and Psychological Measurement, 2016
There are many reasons to believe that open-ended (OE) and multiple-choice (MC) items elicit different cognitive demands of students. However, empirical evidence that supports this view is lacking. In this study, we investigated the reactions of test takers to an interactive assessment with immediate feedback and answer-revision opportunities for…

Paek, Insu – Educational and Psychological Measurement, 2016
The effect of guessing on the point estimate of coefficient alpha has been studied in the literature, but the impact of guessing and its interactions with other test characteristics on the interval estimators for coefficient alpha has not been fully investigated. This study examined the impact of guessing and its interactions with other test…

Harring, Jeffrey R.; Weiss, Brandi A.; Li, Ming – Educational and Psychological Measurement, 2015
Several studies have stressed the importance of simultaneously estimating interaction and quadratic effects in multiple regression analyses, even if theory only suggests an interaction effect should be present. Specifically, past studies suggested that failing to simultaneously include quadratic effects when testing for interaction effects could…

Robitzsch, Alexander; Rupp, Andre A. – Educational and Psychological Measurement, 2009
This article describes the results of a simulation study to investigate the impact of missing data on the detection of differential item functioning (DIF). Specifically, it investigates how four methods for dealing with missing data (listwise deletion, zero imputation, two-way imputation, response function imputation) interact with two methods of…

Liu, Yan; Zumbo, Bruno D. – Educational and Psychological Measurement, 2007
The impact of outliers on Cronbach's coefficient [alpha] has not been documented in the psychometric or statistical literature. This is an important gap because coefficient [alpha] is the most widely used measurement statistic in all of the social, educational, and health sciences. The impact of outliers on coefficient [alpha] is investigated for…

Kowalchuk, Rhonda K.; Keselman, H. J.; Algina, James; Wolfinger, Russell D. – Educational and Psychological Measurement, 2004
One approach to the analysis of repeated measures data allows researchers to model the covariance structure of their data rather than presume a certain structure, as is the case with conventional univariate and multivariate test statistics. This mixed-model approach, available through SAS PROC MIXED, was compared to a Welch-James type statistic.…

Reynolds, Thomas J.; Cliff, Norman – Educational and Psychological Measurement, 1975
Describes the rationale underlying as well as the major features of a computer-interactive APL program IRIS, the objective of which is to obtain an individual's simple ordering of a set of stimuli in as few paired comparison preference judgments as possible. (Author/RC)

Kehoe, Jerard F.; Cliff, Norman – Educational and Psychological Measurement, 1975
INTERORD executes in the interactive mode by presenting pairs to be judged at a remote terminal. The respondent at the terminal judges which one of the objects dominates the other. INTERORD utilized the observed dominance relations to determine which additional relations are implied by the transitivity principle. (Author/RC)

Racioppo, Vincent; And Others – Educational and Psychological Measurement, 1975
This paper presents a revised and updated version of a FORTRAN program which computes all indices used in the Flanders' Interaction Matrix. The new program has added another form of data input which simplifies data entry. The new version also has the capability of interactive terminal use. (Author)

Mossholder, Kevin W.; And Others – Educational and Psychological Measurement, 1990
A convention commonly used to describe interaction effects within moderated regression frameworks was examined through logical exposition and a Monte Carlo approach to simulate various moderator conditions. Results, which indicate that the convention may lead to incorrect inferences, are discussed in terms of interpreting moderator effects. (SLD)

Carter, Jacquelyn; Michael, William B. – Educational and Psychological Measurement, 1995
The Effective School Function Inventory was constructed to operationalize the major constructs of efficient school operation. An analysis with 124 teachers identified 4 meaningful factors: (1) supportive collegial interaction; (2) cooperative facilitation of goal attainment in learning/sharing; (3) morally oriented leadership; and (4)…

Brennan, Robert L.; And Others – Educational and Psychological Measurement, 1995
Generalizability theory is used to examine the psychometric characteristics of the Listening and Writing Tests developed by American College Testing for its Work Keys program. Results with samples of 50 suggest the desirability of a minimum number of the tests' tape-recorded messages and the use of at least 2 raters. (SLD)

Kromrey, Jeffrey D.; Foster-Johnson, Lynn – Educational and Psychological Measurement, 1999
Shows that the procedure recommended by D. Lubinski and L. Humphreys (1990) for differentiating between moderated and nonlinear regression models evidences statistical problems characteristic of stepwise procedures. Interprets Monte Carlo results in terms of the researchers' need to differentiate between exploratory and confirmatory aspects of…
