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…

This article draws on argument-based validation to gather and evaluate construct-related evidence (i.e., the explanation inference) of a high-stakes test. The data stemmed from the listening component of a French test used for immigration to Canada through the province of Quebec. An expert panel with varied backgrounds in applied linguistics…

This paper reports an investigation into the psychometric properties of the COR-Advantage1.5 (COR-Adv1.5) assessment tool, a criterion-referenced observation-based instrument designed to assess the developmental abilities of children from birth through kindergarten. Using data from 8534 children participating in a state-funded preschool program…

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…

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…

This study examined whether the five scales of the MUSIC Model of Academic Motivation Inventory produced valid scores when used in university English language courses across four different countries. We surveyed 1,147 students in English language courses in Iran, Mexico, China, and Egypt and analyzed their responses by performing measurement…

The aim of this research is to develop a reliable and valid scale to determine the mathematical thinking skills of gifted students. In addition, with the developed scale, thinking skills of gifted students was examined in terms of various variables. In this context, the research was carried out on two different study groups. The first stage of…

Early adolescence represents a critical developmental period for the identification, prevention, and early intervention of mental health concerns. The Early Identification System--Student Report (EIS-SR) was developed as a user-friendly, accessible, and cost-efficient method for identifying youth at risk for mental health concerns. The present…

This study aimed to find a valid and reliable self-assessment procedure and instrument to measure the spiritual and social attitude domain of Belief and Morality (Aqidah Akhlak) subject in Madrasah Tsanawiyah by implementing Borg & Gall's research and development model. The instruments' content validity was analyzed using the Aiken formula,…

The purpose of this study is to develop a valid and reliable Likert-type scale that can be used to measure the data literacy skills of educators. In the development process of the scale, after reviewing the relevant literature, a pool of 130 items was designed and presented to the experts for their view. After the evaluation of experts, the…

Although equality of opportunity in education is a current and important issue, most of the studies on this subject are based on theoretical studies rather than empirical studies. The main reason for this can be said to be the lack of a valid and reliable measurement tool in this field. For this reason, this study aims to develop a valid and…

Much of the research that has examined the writing knowledge of school-age students has relied on interviews to ascertain this information, which is problematic because interviews may underestimate breadth and depth of writing knowledge, require lengthy interactions with participants, and do not permit a direct evaluation of a prescribed array of…

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…
