Direct linkA. R. Georgeson – Structural Equation Modeling: A Multidisciplinary Journal, 2025
There is increasing interest in using factor scores in structural equation models and there have been numerous methodological papers on the topic. Nevertheless, sum scores, which are computed from adding up item responses, continue to be ubiquitous in practice. It is therefore important to compare simulation results involving factor scores to…

Model-based attempts to rigorously study the broad and imprecise concept of "discriminating power" are scarce, and generally limited to nonlinear models for binary responses. This paper proposes a comprehensive framework for assessing the discriminating power of item and test scores which are analyzed or obtained using Spearman's…

Diaz, Sebastian R.; Swan, Karen; Ice, Philip; Kupczynski, Lori – Internet and Higher Education, 2010
This research builds upon prior validation studies of the Community of Inquiry (CoI) survey by utilizing multiple rating measures to validate the survey's tripartite structure (teaching presence, social presence, and cognitive presence). In prior studies exploring the construct validity of these 3 subscales, only respondents' course ratings were…

Nering, Michael L., Ed.; Ostini, Remo, Ed. – Routledge, Taylor & Francis Group, 2010
This comprehensive "Handbook" focuses on the most used polytomous item response theory (IRT) models. These models help us understand the interaction between examinees and test questions where the questions have various response categories. The book reviews all of the major models and includes discussions about how and where the models…

Davis, Susan L.; Finney, Sara J. – Educational and Psychological Measurement, 2006
The Cross-Cultural Adaptability Inventory (CCAI) was developed as a tool to assess an individual's effectiveness in cross-cultural interaction and communication. Because limited validity evidence had been published regarding the CCAI, the purpose of the current study is to evaluate the psychometric properties of CCAI scores, specifically focusing…

Cheung, Mike W. L. – Structural Equation Modeling, 2004
Ipsative data (individual scores subject to a constant-sum constraint), suggested to minimize response bias, are sometimes observed in behavioral sciences. Chan and Bentler (1993, 1996) proposed a method to analyze ipsative data in a single-group case. Cheung and Chan (2002) extended the method to multiple-group analysis. However, these methods…

Cantrell, Pamela – School Science and Mathematics, 2003
The difference in gain scores produced by traditional pretests and those produced by retrospective pretests when compared to posttest scores on the Science Teaching Efficacy Belief Instrument for preservice teachers was investigated in this study. Results indicated that gain scores using the traditional pretest produced significant improvement in…
