Considerations related to generalization of a study's findings are often interconnected to researchers' judgements regarding the 'quality' of the methodology and methodological pluralism. Too often, researchers consider generalization as only possible with respect to quantitative studies with large numbers of randomly selected participants…

Research has shown that multiple-indicator multiple-cause (MIMIC) models can result in inflated Type I error rates in detecting differential item functioning (DIF) when the assumption of equal latent variance is violated. This study explains how the violation of the equal variance assumption adversely impacts the detection of nonuniform DIF and…

Measurement invariance (MI) is an essential part of validity evidence concerned with ensuring that tests function similarly across groups, contexts, and time. Most evaluations of MI involve multigroup confirmatory factor analyses (MGCFA) that assume simple structure. However, recent research has shown that constraining non-target indicators to…

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…

The Theory of Mind Inventory-2 (ToMI-2) is a promising measure for assessing theory of mind (ToM) and social-related functions. However, limited evidence on its factorial validity hampers score interpretation. To examine the factorial validity, confirmatory factor analysis for two currently-available structures was performed in 420 typically…

This study aimed to evaluate the tenability of the proposed scoring/interpretive structure for the Woodcock-Johnson IV Test of Cognitive Abilities (WJ IV COG) Standard Battery configuration of subtests using confirmatory factor analysis (CFA) at school age. Results indicated that a three-factor hierarchical model, consistent with the CHC theory…

The consistency of psychometric properties across waves of data collection provides valuable evidence that scores can be interpreted consistently. Evidence supporting the consistency of psychometric properties can come from using a longitudinal extension of item factor analysis to account for the lack of independence of observation when evaluating…

This note is concerned with the benefits that can result from the use of the maximal reliability and optimal linear combination concepts in educational and psychological research. Within the widely used framework of unidimensional multi-component measuring instruments, it is demonstrated that the linear combination of their components that…

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…

Background/purpose: This study aims to examine the validity and reliability of factors influencing students' decisions in selecting the elementary education study program and to identify the most dominant factor. Materials/methods: This quantitative study employed a cross-sectional design involving 722 students from various universities across…

The study aims to verify the validity and reliability of a set of tests for measuring Indonesian students' reading literacy achievement that has been developed by the Center for Language Strategy and Diplomacy Development as well as the Educational Assessment Center, two institutions under the auspices of the Ministry of Education, Culture,…

Metacognition awareness is a fundamental skill for the 21st century. Accurately measuring metacognitive awareness would be highly relevant regardless of age, background, or cognitive abilities. The current study aimed to evaluate the psychometric properties of the 19-item Metacognitive Awareness Inventory-Arabic version (MAI-A) in the general…

Current environmental risks, such as climate change and nature loss, force us to look for solutions in every sector of society. A successful sustainability transition requires the manipulation of deep systemic leverage points. Hence, a deep leverage point framework based on sustainability competencies is needed to conceptualise sustainability…

Previous studies have linked religiosity to a variety of positive outcomes for young people. However, further investigation into the underlying mechanisms that drive this connection is necessary to facilitate these positive outcomes. Some studies have suggested that afterlife reward and punishment beliefs play a role in this connection, as they…

Over the past decades, the demand for scientific research to link theory and practice so that innovative solutions can be developed through research has steadily increased (Klees & Tillmann, 2015; Sandoval & Bell, 2004). In this context, the design-based research (DBR) approach was developed, which examines the research object and the…
