This note demonstrates that measurement invariance does not guarantee meaningful and valid group comparisons in multiple-population settings. The article follows on a recent critical discussion by Robitzsch and Lüdtke, who argued that measurement invariance was not a pre-requisite for such comparisons. Within the framework of common factor…

A frequent criticism of exploratory factor analysis (EFA) is that it does not allow correlated residuals to be modelled, while they can be routinely specified in the confirmatory (CFA) model. In this article, we propose an EFA approach in which both the common factor solution and the residual matrix are unrestricted (i.e., the correlated residuals…

Background/Context: Confirmatory factor analysis (CFA) model is a commonly adopted framework to estimate and test a measurement model. Once a well-fitting final CFA model is selected, the selected model may be used to test structural relationships of the latent constructs with other variables, to construct a test with desired reliability and…

The p-factor is a construct that is thought to explain and maybe even cause variation in all forms of psychopathology. Since its 'discovery' in 2012, hundreds of studies have been dedicated to the extraction and validation of statistical instantiations of the p-factor, called general factors of psychopathology. In this Perspective, we outline five…

According to cognitive load theory, learning can only be successful when instructional materials and procedures are designed in accordance with human cognitive architecture. In this context, one of the biggest challenges is the accurate measurement of the different cognitive load types as these are associated with various activities during…

The population relationship between coefficient alpha and scale reliability is studied in the widely used setting of unidimensional multicomponent measuring instruments. It is demonstrated that for any set of component loadings on the common factor, regardless of the extent of their inequality, the discrepancy between alpha and reliability can be…

Objective: This study examines the psychometrics of the 15-item version of the Five-Factor Mindfulness Questionnaire (FFMQ-15). Participants: An ethnically diverse sample of 538 college students participated in this study. Methods: The factor structure was evaluated through confirmatory factor analyses fitting 64 alternative models with and…

There is no need or point to testing of knowledge, attributes, traits, behaviours or abilities of an individual if information obtained from the test is inaccurate. However, by and large, it seems the estimation of psychometric properties of test items in classroomshas been completely ignored otherwise dying slowly in most testing environments. In…

We examined dimensionality and temporal stability of the Interpersonal Stress Scale-Counselor (ISS-C) scores in a sample of professional counselors (n = 518). Confirmatory factor analyses provided support for a four-factor model previously identified through exploratory factor analysis and a bifactor model. Using a randomized test-retest, temporal…

In adult learning and education the need is defined as the discrepancy between the current stage of development of professional competences, as well as those of general culture, and the desired (possible to be achieved) stage. The need reflects the existence of a problem that requires intervention, a problem that needs to be dealt with, but also a…

This quantitative research sought to answer two questions: (a) What is the factor structure of emic and etic constructs?; and (b) How much do the extracted factors explain the variance of emic and etic constructs within the survey? These questions were answered through the use of an exploratory factor analysis. A total of 294 counselors…

This study was conducted to explore the five-factor structure of the Need for Closure scale on Indian samples using exploratory and confirmatory factor analysis. Data were initially collected from 450 samples which were reduced to 235 cases later based on the lie score criteria of the Need for Closure Scale. To rule out the problems caused by all…

This article reviews the administrative, scoring, and psychometric properties of the Wechsler Individual Achievement Test, Fourth Edition (WIAT-4, NCS Pearson, 2020). The WIAT-4 is one of the more commonly administered broadband measures of academic achievement. The instrument was determined to be well-conceptualized, and generally…

Retention concerns remain high for postsecondary institutions and even more so when focusing on populations such as those who are the first in the family to attend college, first-generation college students. First-generation students account for 34% of the collegiate population, yet 40% of first-generation students do not return for their…

This study presents the Cebeci Test of Creativity (CTC), a novel computerized assessment tool designed to address the limitations of traditional open-ended paper-and-pencil creativity tests. The CTC is designed to overcome the challenges associated with the administration and manual scoring of traditional paper and pencil creativity tests. In this…
