Objective: The purpose of this study was to begin developing and validating an instrument to measure self-trust in adults. Method: Using a multi-phased and mixed methods approach to instrument development, the RSTI scores were tested across three samples reflecting national demographics of adults in the United States (n = 157, n = 692, n = 261).…

Executive function (EF) is frequently an area of vulnerability in conditions associated with intellectual disability, like Down syndrome (DS). However, current EF evaluation approaches are not designed for children with underlying neurodevelopmental conditions and may not demonstrate construct validity due to interpretational confounds. The…

The present study evaluated the validity of the Online Learner Satisfaction Instrument (OLSI) in terms of construct and convergent validity, and measurement invariance across demographic groups. The study results revealed that the factor structures generally confirmed to the original factor structure proposed in the instrument. Also, some…

Quality of collaborative group engagement (QCGE) is conceptualised as a complex, shared, and multidimensional construct critical to learning outcomes in collaborative learning. It is currently measured in a variety of ways, including rich observation-based methods. However, a standardised self-assessment method for the construct of QCGE has not…

The Strengths and Difficulties Questionnaire (SDQ) is a brief instrument developed primarily for screening children and adolescents for social-emotional learning. The SDQ contains four factors related to socio-emotional difficulties and one factor related to prosocial behaviour. However, studies of its factor structure have produced mixed results.…

This study aimed to develop a scale to measure teachers' digital assessment literacy self-efficacy. Teachers were selected from all regions of Turkey and different branches at primary, secondary, and high school levels to enhance generalization and diversity. The data was collected from 314 teachers for the exploratory factor analysis and 296 for…

This research aims to develop an instrument for the evaluation of impulsivity traits in children and to examine the psychometric features of the developed scale. The process of developing the scale involved three main phases: namely, item generation, evaluation of content validity, and analysis of psychometric properties. The study sample…

Effective collaboration depends on the mutual regulation of group members, positioning it as a fundamental aspect of socially shared regulation of learning (SSRL). In recent years, SSRL has garnered increasing research attention. However, there remains a scarcity of psychometrically sound measures for assessing this construct. Without reliable…

Quality academic advising has been known to have lasting impacts on student success and persistence in higher education. In 2017, NACADA: The Global Community for Academic Advising established a set of 20 competencies known to be the essential topics that advisors and student success professionals have an understanding of, knowledge of, or skills…

As well as being important tools for information acquisition, children's questions can also lead to profound learning. Nevertheless, no scale for measuring their questioning tendencies has hitherto been developed. Accordingly, this study pioneers one for use with preschool children. To establish construct validity, data from 544 children were used…

The aim of this study was to develop and validate a psychometrically-sound instrument to assess students' perceptions about class cohesion. Two studies were conducted. In Study 1, four steps were established: (1) development of the Class Cohesion Questionnaire (CCQ); (2) item selection; (3) item compression; and (4) exploration of psychometric…

Introduction: The objective was to evaluate the factor structure and propose a new version of the Rosenberg Self-Esteem Scale with only positive items to overcome the method effect associated with negative items. Method: A version A (positive and negative items) and a version B (only positive items) were considered. A sample of 350 university…

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…

Grit--"perseverance and passion for long-term goals" (Duckworth, Peterson, Matthews, & Kelly, 2007, p. 1087)--has attracted the attention of researchers in fields ranging from psychology to business to education (e.g., Robertson-Kraft & Duckworth, 2014; Robins, 2019). Continuing the line of research that explores the domain…

In this study, a valid and reliable scale (TSSSSS) was aimed to develop to measure secondary school students' perceptions of teacher support. The research was carried out on a total of 773 students studying in 6 different secondary schools in Ankara's Yenimahalle district in the Spring Term of the 2021-2022 Academic Year. The students who…
