The present study adapted the "questionnaire of Internet use motives" (MUI) into Turkish based on data collected from 638 adults. Results showed that the Turkish version of the MUI has a high internal consistency ([alpha]= 0.88) along with convergent and discriminant validity. The confirmatory factor analysis results supported the…

A principals' school management imaginative capability is the cornerstone of visionary leadership. Based on the imagination theory, this study constructed a Principal's School Management Imaginative Capability Scale (PSMICS). Questionnaires were conducted through stratified random sampling. Thirteen hundred and two valid samples were obtained.…

Factor analysis of ordered categorical indicators in kinesiology is pervasive. However, some assumptions made regarding the indicators within methods commonly used in this research may increase analytic errors. Methods that relax these assumptions have been available for decades, but uptake has been slow. Therefore, the methodological focus of…

The way in which validity has been conceptualized has changed throughout the years. The focus in validation studies shifted from evaluating distinct components of validity to developing a comprehensive argument for the use and interpretations of test scores. The argument-based approach to validity incorporates the distinct types of the…

A teacher competency instrument was developed to determine the level of teacher competency in small schools in Peninsular Malaysia. This study was conducted in Perak and Negeri Sembilan to determine the instrument's reliability and validity. Exploratory factor analysis (EFA) and item reliability analysis were used to determine the questionnaire's…

Background/purpose: This study aimed to investigate the differences among the equations used in estimating the reliability coefficient using the half-split method. These equations demonstrate Spearman-Brown's, Rulon's, Guttman's, Mosier's, Flanagan's, and Horst's. Materials/methods: The study instrument was a 43-item scale for evaluating the…

Background/purpose: Moral leadership is essential to foster ethical, effective school management and create positive educational environments. Existing moral measurement instruments focus on general morality, and there is a lack of tools tailored to assess the moral leadership of prospective primary school principals in Indonesia. This study aims…

Background: The study focuses on the need to optimise assessment scales for support needs in individuals with intellectual and developmental disabilities. Current scales are often lengthy and redundant, leading to exhaustion and response burden. The goal is to use machine learning techniques, specifically item-reduction methods and selection…

This study was undertaken to set a novel developmental screening test for autism spectrum disorder (ASD) using the Griffiths Scales of Child Development (Griffith III) (Green et al., 2016; Stroud et al., 2016), in order to intercept the early atypical developmental patterns indicating ASD risk in the first 3 years of age. An observational and…

Purpose: The purpose of this study was to evaluate the construct validity of three sentence-focused diversity measures, intransitive verb diversity, transitive verb diversity, and third person (3P) subject diversity, using two methods: (a) group differentiation of late-talking (LT) toddlers from peers with typically developing (TD) language and…

The aim of this study is to examine the available scientific evidence on the reliability and criterion validity of 6-minute run walk field-based test when administered to children and adolescents. Systematic searches were performed in three electronic databases (MEDLINE/PubMed, SPORTDiscuss and Scopus) from their inception until February 2024,…

Field-based tests of aerobic fitness that can be administered quickly and do not require maximal effort are desirable. The purpose was to develop and validate quarter-mile walk tests for 10--13-year-olds. Participants (N = 59) walked one mile on two different days. Walk times, heart rates, body mass, physical activity, and aerobic fitness were…

Academic engagement plays a crucial role in students' learning and performance. One of the most popular measures for assessing this construct is the Utrecht Work Engagement Scale for Students (UWES-S), which is based on a tridimensional conceptualization consisting of dedication, vigor, and absorption. However, prior research on its factor…

The KeyMath-3 Diagnostic Assessment (KM-3) is an individually-administered math assessment used in educational placement and diagnostic decisions. It includes 10 subtests making up Basic Concepts, Operations, and Applications indexes and a "Total Test" composite that measures overall math ability. Here, covariances among subtests from…

This study uses a rigorous research process to explore the psychometric properties of the Gifted Rating Scale-School Form (GRS-S) within the Qatari educational context. We employed stratified cluster sampling of 326 students (aged 6-13 years, M = 10.9) from 25 public schools in Doha. Data was collected in the second semester of the 2023-2024…
