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…

The problem of local item dependencies (LIDs) is very common in personality and attitude measures, particularly in those that measure narrow-bandwidth dimensions. At the structural level, these dependencies can be modeled by using extended factor analytic (FA) solutions that include correlated residuals. However, the effects that LIDs have on the…

A questionnaire for measuring Context University Skills and Workplace-Recognized Skills (LCUS-WRS) requires a validated and reliable instrument. The purpose of this study was to develop and validate a questionnaire to measure learning of context university skills and workplace-recognized skills, in order to carry out an advanced psychometric…

Within educational and social discourses, the term 'inclusion' has various meanings. In both research and practice, there is no official definition of inclusion. Nevertheless, subjective definitions affect pedagogical acts. We developed the Definitions of Inclusion Questionnaire ["Fragebogen zur Erfassung subjektiver Definitionen von…

This study aims to compare the results of the factor analysis performed with Frequentist and Bayesian approaches. The number of sub-dimensions of the measurement tool obtained from different methods, the variation of the items in the sub-dimensions, and the fit statistics' differentiation were examined. 778 students constitute the study sample.…

This study sought to propose the Undesirable Behavior Strategies Questionnaire--Physical Education (UBSQ-PE), based on Doyle, W. (1977). Paradigms for research on teacher effectiveness. "Review of Research in Education," 5(1), 163-198. classroom ecology paradigm, and validate its use within Physical Education. 289 physical educators…

This multiple-manuscript dissertation explored the measurement invariance (MI) testing with multiple-group confirmatory factor analysis (MG-CFA) approach from different perspectives. Study 1 explored MI from a theoretical perspective by conducting a systematic review study on MI practices in education. The findings of this study indicated…

The study examined the validity of the scores produced by the Albanian version of the Olweus Bullying Questionnaire-Revised (OBQ-R), a self-reported measure for assessing the phenomena of bullying among school students. A sample of third to ninth grade students (N = 3262) completed the OBQ-R and the data were analyzed using an exploratory factor…

In higher education, it is essential that students apply what they have learned to solve problems in their community. Meaningful learning is the main means to increase the accumulation of knowledge and achieve the transfer of learning, which is why the present study aimed to: design and evaluate the psychometric properties of a scale that measures…

Examining the long-term impact of bullying can facilitate using retrospective bullying experiences questionnaire (RBEQ) which provides information regarding bystander, bully and victim through childhood to adolescence. This study aimed to investigate the validity and reliability of this questionnaire in Iranian samples. A total of 92 male and 283…

Non-formal adult education (NFE) provides adults of all ages with the opportunity to acquire skills, knowledge, and expertise. However, there is currently a lack of validated instruments that measure the factors of NFE non-participation in European countries, particularly their barriers. One exception is the Non-participation in Non-formal…

Students who are self-regulated leaners have been reported to perform more successfully in higher education institutions (HEIs). Therefore, instruments that can monitor students' motivation and learning have been devised and implemented. The aims of this work were to investigate the dimensionality of the motivated strategies for learning…

The instrument that assesses teachers' competence on AR methodology is limited. Thus, it is one of the issues concerning evaluating the effectiveness of a professional development program on designing AR projects. It is difficult to determine how much and what teachers have learned in a course or training. Thus, this cross-sectional study aimed to…

This study created a Spanish triangulated version of the European Bullying Intervention Project Questionnaire and obtained indicators of its validity and reliability. This new tool allows researchers to triangulate and flexibly investigate the three main roles in school bullying, obtaining seven potential roles (pure victim, pure bully, pure…

This study focused on the assessment of the structural validity of the 28 item adapted Teacher Assessment for Learning Questionnaire (TAFL-Q) in the Kenyan context. The sample consisted of 180 mathematics teachers drawn from 50 secondary schools. Confirmatory factor analysis was used to confirm the hypothesised two-factor model of the original…
