Waller, Niels G. – Journal of Educational and Behavioral Statistics, 2023
Although many textbooks on multivariate statistics discuss the common factor analysis model, few of these books mention the problem of factor score indeterminacy (FSI). Thus, many students and contemporary researchers are unaware of an important fact. Namely, for any common factor model with known (or estimated) model parameters, infinite sets of…

Wise, Lauress L. – Applied Measurement in Education, 2010
The articles in this special issue make two important contributions to our understanding of the impact of accommodations on test score validity. First, they illustrate a variety of methods for collection and rigorous analyses of empirical data that can supplant expert judgment of the impact of accommodations. These methods range from internal…

Salahuddin, Nazish M.; O'Brien, Karen M. – Journal of Counseling Psychology, 2011
Multiracial Americans represent a rapidly growing population (Shih & Sanchez, 2009); however, very little is known about the types of challenges and resilience experienced by these individuals. To date, few psychological measures have been created specifically to investigate the experiences of multiracial people. This article describes 2…

DiStefano, Christine; Zhu, Min; Mindrila, Diana – Practical Assessment, Research & Evaluation, 2009
Following an exploratory factor analysis, factor scores may be computed and used in subsequent analyses. Factor scores are composite variables which provide information about an individual's placement on the factor(s). This article discusses popular methods to create factor scores under two different classes: refined and non-refined. Strengths and…

Lee, Sang Min; Moon, Kyoung-Suk; Puig, Ana; Cho, Eunsoo; Lee, Sun Young; Back, Sun Hee; Woo, Yeon Kyoung – Measurement and Evaluation in Counseling and Development, 2008
The authors describe the development and psychometric properties of the Korean Mood State Inventory (KMSI), which is designed to measure the mood states of Korean college students. Factor structure, concurrent validity, and internal consistency of the KMSI scores are reported. Implications, limitations, and recommendations for future research are…

Lubke, Gitta H.; Muthen, Bengt O. – Structural Equation Modeling, 2004
Treating Likert rating scale data as continuous outcomes in confirmatory factor analysis violates the assumption of multivariate normality. Given certain requirements pertaining to the number of categories, skewness, size of the factor loadings, and so forth, it seems nevertheless possible to recover true parameter values if the data stem from a…

Marsh, S. Neil – 2001
This paper explains the meaning and use of three important factor analytic statistics: factor scores, factor structure coefficients, and communality coefficients. For the discussion, 301 observations of junior high school students 11 measured variables from a previous study are analyzed. While factors provide the researcher with general…

Raines-Eudy, Ruth – Structural Equation Modeling, 2000
Demonstrates empirically a structural equation modeling technique for group comparison of reliability and validity. Data, which are from a study of 495 mothers' attitudes toward pregnancy, have a one-factor measurement model and three sets of subpopulation comparisons. (SLD)
