The Cognitive Test Anxiety Scale (CTAS) is a unidimensional scale designed to measure the cognitive aspect of test anxiety. The instrument has been adapted in several countries, and convincing psychometric properties have been found; however, uncertainties remain regarding its factor structure. Therefore, the aim of this study is twofold: to…

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…

Introduction: Numerous studies have investigated the use of Wechsler tests on individuals with visual impairments. However, few studies have examined the utilization of the fourth edition of the Wechsler Intelligence Scale for Children (WISC-IV) for such individuals. This study investigated the reliability and validity of the WISC-IV Verbal…

The present investigation explored the psychometric validity of the five-item Gratitude Questionnaire (GQ-5) using a construct validation approach. Concerning within-network construct validity, results of item response theory (IRT) analysis via graded response model (GRM) showed that this scale could not discriminate individuals who score high in…

The study revisited the community of inquiry (CoI) instrument for construct revalidation. To that end, the study used confirmatory factor analysis (CFA) to examine four competing models (unidimensional, correlated-factor, second-order factor, and bifactor models) on model fit statistics computed using parameter estimates from a statistical…

It is widely believed that subscores can give us more information about an examinee. Thus they can be useful in planning instructional and remedial efforts, or making vocational or academic placement decisions. However, past research has shown that subscores are often not as useful as hoped either because they do not have high reliability or…

The Physics Independent Learning (PIL) model is an authentic problem-based model designed teaching guide for improving self-directed learning and problem-solving skills in open and distance education. This research is aimed to analyze the validity and effectiveness of PIL model. This research was conducted using focus group discussions of experts…

Objectives: The purpose of this study was to examine the construct and predictive validity of the Adult-Adolescent Parenting Inventory (AAPI-2). Methods: The validity of the AAPI-2 was evaluated using multiple statistical methods, including exploratory factor analysis, confirmatory factor analysis, and latent class analysis. These analyses were…

Purpose: Our purpose was to explore the validity and reliability of the German Focus on the Outcomes of Communication Under Six (FOCUS-G; Thomas-Stonell, Oddson, Robertson, & Rosenbaum, 2010, 2012), which is an authorized adaptation of the Focus on the Outcomes of Communication Under Six (Thomas-Stonell et al., 2010) tool, which measures…

Background: Measuring adolescent perceptions of physical education (PE) activities is necessary in understanding determinants of school PE activity participation. This study assessed reliability and validity of the Physical Education Activities Scale (PEAS), a 41-item visual analog scale measuring high school adolescent perceptions of school PE…

Paul E. Newton's article on the consensus definition of validity tackles a number of big issues and makes a number of strong claims. I agreed with much of what he said, and I disagreed with a number of his claims, but I found his article to be consistently interesting and thought provoking (whether I agreed or not). I will focus on three general…

The current study used work values components (WVC) to examine the relationship between work values, vocational interests, personality, and personal values. Most intercorrelations between work values and other constructs were in the small effect range. Overall correlations between scale scores provided evidence of convergent and discriminant…

This is the first UK study to report the reliability, validity, and factor structure of the Social Responsiveness Scale (SRS) in a general population sample. Parents of 500 children (aged 5-8 years) in North East England completed the SRS. Profiles of scores were similar to USA norms, and a single factor structure was identified. Good construct…

This paper presents the authors' critique on "Clarifying the Consensus Definition of Validity" by Paul E. Newton (this issue). There are serious differences of opinion regarding the topic of validity. Newton is aware of these differences, as made clear by his choice of references and particularly his effort to respond to the various Borsboom…

To validate an interpretation or use of test scores is to evaluate the plausibility of the claims based on the scores. An argument-based approach to validation suggests that the claims based on the test scores be outlined as an argument that specifies the inferences and supporting assumptions needed to get from test responses to score-based…
