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…

This study aims to examine the psychometric properties of a scale developed to measure teachers' ability to use artificial intelligence tools in education. The scale was originally proposed as having 33 items across 5 sub-dimensions by Chat GPT-4, an AI system. To establish content validity, the scale form was submitted to expert review. An…

Evaluation of child-friendly school (CFS) policies is essential to determine the achievements of school efforts in reducing violence cases. This research aims to proving the reliability and validity of CFS policy evaluation instruments in elementary schools with different locations. This investigation uses the Context Input Process Product (CIPP)…

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…

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…

The Career Adapt-Abilities Scale (CAAS) is one of the most widely used measures to assess career adaptabilities. Despite intensive worldwide use across heterogeneous populations, no study has assessed its factorial validity in the not in education, employment, or training (NEET) population. This study aims to extend evidence of CAAS factorial…

The aim of this study is to find evidence of factorial validity, measure equivalence by gender, and internal consistency of the Mental Health Continuum-Short Form (MHC-SF) in a sample of Ecuadorian teenagers. The study uses a psychometric design to explore the validity and reliability of the measure. Participants of the study were 1154 teenagers…

This paper reports an investigation into the psychometric properties of the COR-Advantage1.5 (COR-Adv1.5) assessment tool, a criterion-referenced observation-based instrument designed to assess the developmental abilities of children from birth through kindergarten. Using data from 8534 children participating in a state-funded preschool program…

Locus of Control (LOC) is a general term used in social and educational psychology to refer to the perceived source of control for behavioural outcomes. Since the 1980s, various instruments have been developed to measure this construct in relation to pro-environmental behaviours and action. In this article, we revisit the value of this construct…

Background: Although the Depression Anxiety Stress Scales, Short Form (DASS-21) was developed for adults, its authors noted no compelling reasons to not use the measure with youth as young as 12 years. Despite increasingly widespread use with youth, psychometric evidence in support of its use with this population needs to be investigated to fully…

Although equality of opportunity in education is a current and important issue, most of the studies on this subject are based on theoretical studies rather than empirical studies. The main reason for this can be said to be the lack of a valid and reliable measurement tool in this field. For this reason, this study aims to develop a valid and…

The study examined the psychometric structure of Basic Needs Satisfaction in General Scale (BNSG-S) with a sample of 495 college students. It compared the original 21-item version (Gagné, 2003) with the shortened 16-item version (Johnston & Finney, 2010), both with and without method effects. A series of confirmatory factor analyses (CFA)…

This study was conducted to develop an instrument with good psychometric properties to measure primary school students' attitudes towards mathematics. For this purpose, the screening model was utilised in the research. The form was prepared in the form of a five-point Likert scale (Very Unhappy, Unhappy, Neither Happy nor Unhappy, Happy, Very…

Although the original long version of the Hewitt Multidimensional Perfectionism Scale (HMPS) has been translated and validated in a Spanish population, no study to date has examined the psychometric properties of a short version of the HMPS with a Spanish-speaking sample. For this reason, the aim of this study is to analyze the psychometric…
