Several crucial reasons exist to determine whether an adult has had a reading disorder (RD) and to predict a child's likelihood of developing RD. The Adult Reading History Questionnaire (ARHQ) is among the most commonly used self-reported questionnaires. High ARHQ scores indicate an increased likelihood that an adult had RD as a child and that…

The purpose of this study is to identify which scale short-form development method produces better findings in different factor structures. A simulation study was designed based on this purpose. Three different factor structures and three simulation conditions were selected. As the findings of this simulation study, the model-data fit and…

This study examined the psychometric properties of the Career Transition Inventory after translation into Turkish (TR). A sample of 339 Turkish residents who had undergone a career transition completed the CTI-TR to test construct validity. A second sample of 184 individuals in career transition completed the CTI-TR, the Integrated Hope Scale and…

Unit-weight sum scores (UWSSs) are routinely used as estimates of factor scores on the basis of solutions obtained with the nonlinear exploratory factor analysis (EFA) model for ordered-categorical responses. Theoretically, this practice results in a loss of information and accuracy, and is expected to lead to biased estimates. However, the…

Researchers frequently use Rasch models to analyze survey responses because these models provide accurate parameter estimates for items and examinees when there are missing data. However, researchers have not fully considered how missing data affect the accuracy of dimensionality assessment in Rasch analyses such as principal components analysis…

There is an expectation that health professions schools respond to priority societal health needs. This expectation is largely based on the underlying assumption that schools are aware of the priority needs in their communities. This paper demonstrates how open-access, pan-national health data can be used to create a reliable health index to…

The importance of understanding student attitudes has become paramount in the successful deployment of blended learning. This study aimed to examine the factorial structure of a scale designed to assess university students' attitudes towards blended learning. Using a descriptive quantitative research approach, the study included a sample of 889…

The Multidimensional Personality Questionnaire (MPQ) measures a wide range of personality traits associated with affect and temperament. However, the lengthy administration time may have hindered its widespread use in personality research. The National Survey of Midlife Development in the United States (MIDUS) has adapted a short version of the…

The current study involved the development, scaling, and validation of a new, brief, strength-based measure of children's ecological support, as rated by their parents. The scaling and validation of the Child and Youth Ecological Assets Scale--Parent Form (C-YEAS-P) took place through two studies. The first study involved 500 parents who were…

Determining the number of factors in exploratory factor analysis (EFA) is crucial because it affects the rest of the analysis and the conclusions of the study. Researchers have developed various methods for deciding the number of factors to retain in EFA, but this remains one of the most difficult decisions in the EFA. The purpose of this study is…

This study examined the factorial composition and cultural invariance of the online learning readiness self-check (OLRSC) survey across Turkish (N = 212), Romanian (N = 207), and Polish (N = 235) college students. The results of confirmatory factor analyses (CFA) in individual samples supported the six-dimensional structure of online learning…

Many universities use diagnostic tests to assess incoming students' preparedness for mathematics courses. Diagnostic test results can help students to identify topics where they need more practice and give lecturers a summary of strengths and weaknesses in their class. We demonstrate a process that can be used to make improvements to a mathematics…

The present study developed and validated a self-regulated learning (SRL) teaching scale with a total sample of 966 preschool teachers. A pool of items was generated from literature reviews, teacher interviews, and expert reviews using Zimmerman's cyclical model of SRL. An exploratory factor analysis (N = 333) in study 1, and a confirmatory factor…

"Grit" is a stable and measurable trait. It refers to the individual's ability to maintain efforts and interest in projects that take time to complete and are useful in educational contexts. In this study we investigated the validity of a short version of the Grit |International Assessment Scale, Portuguese Version (EAGrit-LP) based on…

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,…
