This study is a conceptual replication of Teimouri et al.'s (2022) investigation into the validity of the second language (L2) grit scale (the L2-Grit scale). There are several concerns about the generalizability of the findings of Teimouri et al. (2022), especially regarding the discriminant validity of the scale and the relation of L2 grit with…

This study was conducted to develop a measurement tool to achieve epilepsy self-management in teachers and examine its Turkish psychometric properties. This descriptive, comparative, correlational, and methodological study was conducted between May and August 2022 with 346 teachers between the ages of 24 and 67 working in public schools selected…

Blended learning modes are becoming the norm in educational institutions. This research investigates the factors affecting teacher satisfaction with online lesson delivery. This study was undertaken in primary, secondary, and higher education institutions across ten countries worldwide. A total of 247 teachers responded to the survey. This work…

The patient health questionnaire-9 (PHQ-9) is widely utilized in assessing individuals' depression levels. Nevertheless, research regarding its factor structure and measurement invariance remains inadequate. The aim of this study was to delve into the factor structure of the PHQ-9 and to further investigate its measurement invariance across gender…

Examinations of the internal structure of the Depression, Anxiety, and Stress Scale-21 (DASS-21) have yielded inconsistent conclusions within and across cultural contexts. This study examined the dimensionality and reliability of the DASS-21 across three theoretically plausible factor structures (i.e., unidimensional, oblique three-factor, and…

Background/purpose: Depressive symptoms are prevalent in student-athletes. Evidence for the factorial validity of measures assessing depressive symptoms in student-athletes is presently absent from the literature. This study examined the best fitting factorial structure and invariance across sexes of the PHQ-9. Methods: Data were collected from…

Mathematical abstraction skills are fundamental for advanced reasoning and problem-solving, yet assessing these skills in senior high school students poses challenges due to limited validated instruments. This study aims to develop and validate a test instrument for measuring mathematical abstraction skills in Indonesian high school students. The…

Handwriting is a perceptual-motor skill encompassing a series of psychomotor skills related to academic performance. The main aim of this study was to translate and study the psychometric properties of the Handwriting Proficiency Screening Questionnaire for Children (HPSQ-C) for the Spanish population. A study was conducted on a final sample of…

Evidence of positive associations between the frequency of home math activities and preschool children's math skills is mixed, and the operationalization of home math activities varies across studies. We test whether home math activities can be grouped by activity factors based on the math subdomain they target (i.e., counting and cardinality,…

This research examines the performance of the previously proposed cutoff values of alternative fit indices (i.e., change in comparative fit index [(delta)CFI], change in Tucker-Lewis index [(delta)TLI], and change in root mean squared error of approximation [(delta)RMSEA]) to evaluate measurement invariance for exploratory structural equation…

Background: This paper presents psychometric properties of an instrument for the Assessment of Sexual Behaviour and Knowledge of people with Intellectual Disability (ASBKID), other-reported by professionals who are in daily contact with them. Methods and procedures: Assessments of 236 individuals with intellectual disability were obtained from 100…

This study describes a psychometric evaluation of high school student responses to the Colorado Learning Attitudes about Science Survey (CLASS), and the subsequent development of a more parsimonious attitudes and beliefs survey structure for potential use with K-12 students in physics courses aligned with the Next Generation Science Standards.…

To date, the Intentions to Seek Counseling Inventory (ISCI) is the most widely used instrument to measure psychological help-seeking intentions. However, the ISCI is yet to be validated with international students. In this study, we examine the dimensionality and reliability of the ISCI by performing exploratory factor analysis, Cronbach alpha…

This article describes the development of an instrument for examining schools as institutions where teaching practices and school structures provide opportunities and support for student imagination, creativity, and innovation, as well as initial comparisons using the instrument, using a sample of n = 5020 students and n = 268 teachers (n = 161…

It remains unclear whether pragmatic language skills and core language skills (grammar and vocabulary) are distinct language domains. The present work aimed to tease apart these domains using a novel online assessment battery administered to almost 400 children aged 7 to 13 years. Confirmatory factor analysis indicated that pragmatic and core…
