The aim of this study was to develop a valid and reliable measurement instrument to find out adolescents' relative deprivation levels and to determine the statistical characteristics of the instrument. The Relative Deprivation Scale-Adolescent Form was prepared and applied to 586 adolescents within the scope of the study. Exploratory Factor…

Evaluation scholars have committed decades of work to the development of evaluator competencies. The 2018 American Evaluation Association (AEA) Evaluator Competencies may be useful for evaluators to identify their strengths and weaknesses to improve their practice; however, a few empirically validated self-assessment tools based on the…

When comparing relations and means of latent variables, it is important to establish measurement invariance (MI). Most methods to assess MI are based on confirmatory factor analysis (CFA). Recently, new methods have been developed based on exploratory factor analysis (EFA); most notably, as extensions of multi-group EFA, researchers introduced…

Purpose: Given the importance of teacher leadership in influencing, motivating and inspiring student learning engagement and associated learning outcomes, a robust instrument to assess this construct is critical. Although there are some teacher leadership instruments available in existing literature, efforts to adapt robust psychometric…

Disengagement is considered a significant component that affects the success, participation, and activity of the students in the online course. Reviewing the literature revealed the lack of a measurement tool for assessing students' disengagement in online courses. This study aimed to develop a scale that examines student disengagement in online…

The present study examined the posited structure of the Wechsler Intelligence Scale for Children--Fifth Edition (WISC-V) ancillary index scores with normative sample participants aged 6-16 years (N = 2200) using a series of confirmatory factor analyzes (CFA) with maximum likelihood estimation. CFA results supported the retention of auditory…

The aim of this study was to develop a measurement tool to determine teachers' perceived emotional job demands. The item pool created as a result of a literature review conducted by researchers was subjected to expert evaluation for content, appearance, and meaning validity, and finally, a draft scale form was created. The draft form was applied…

While generative artificial intelligence (AI) empowers students in their learning, it may also have the potential to undermine their learning agency. Understanding student learning agency in the generative AI-supported contexts (SLA-GAI) has become critical for educators. However, student learning agency is a domain-specific construct, current…

An interdisciplinary curriculum provides integration of students' subjects and lives, guiding students to understand and engage with changes in the world through real situations and problems, with teachers playing a critical role. However, there is no assessment tool to explore teachers' interdisciplinary role perceptions (TIRP). In this study, an…

This study was conducted to validate the measurement model of the awareness of e-waste management among secondary school students. The study's respondents consisted of 1,000 students from Malaysian secondary schools, who were selected using a simple random sampling technique based on their school level. The constructs studied were knowledge,…

Background: Professor-student rapport is associated with various important student success outcomes, highlighting the need for a good measure of this construct. Objective: The current study attempted to replicate the components of the Professor-Student Rapport Scale (PSRS) reported in Wilson and Ryan (2013). Method: 760 undergraduate students…

Objectives: Food and Alcohol Disturbance (FAD) is the phenomenon in which individuals exhibit co-occurring hazardous alcohol and eating behaviors to either negate caloric intake associated with alcohol and/or maximize intoxication. While the Compensatory Eating and Behaviors in Response to Alcohol Scale (CEBRACS) is the most widely used measure to…

Bullying is a form of school violence that has recently received the attention of school psychologists. One of these problems that exists in almost all schools is the phenomenon of school bullying. The aim of this study is to examine the psychometric reliability and validity of the Participant Role Scale in bullying in Persian and compare the…

The purpose of this study was to examine the psychometric properties of the Self-Efficacy Questionnaire for Online Learning (SeQoL; Shen et al., 2013). Using two samples of college students, this study examined evidence of construct validity, concurrent validity, convergent validity, and reliability for the SeQoL. Confirmatory factor analysis and…

It is widely recognized that students encounter difficulties with proof across all grades and beyond, yet standardized instruments related specifically to students' perceived self-efficacy for mathematical proof have not been readily available. The purpose of this study was to develop and investigate preliminary validity evidence for a new…
