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…

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…

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…

The goal of the present study was to investigate the factor structure of the Bullying Participant Behaviors Questionnaire in an independent elementary school sample. The BPBQ is a self-report inventory that purports to measure participation or experiences in five bullying roles: perpetrator, target, assistant, defender, and outsider. The current…

The purpose of the study is to validate the 54-item Fitness Switching Costs Scale (FSCS). The FSCS consists of a third-order formative construct with four second-order formative constructs and 11 first-order reflective constructs. Although there was support for the reliability and validity of higher-order constructs, validity of the 11 first-order…

The present article describes the development and validation of the Informational and Normative Conformity Scale (SKI-N), a brief self-report tool capturing adolescents' general propensity to adopt a conformist attitude, and the underlying motives for doing so. The presentation includes a description of scale construction and an assessment of the…

Exploring the individual differences of the longitudinal growth of early numeracy (EN) in young children with Intellectual disabilities (IDs) prerequires the critical stage of exploring and validating the potential factor structure. Despite the fact that Relational Skills (RS), Counting Skills (CS) and Operations (O) are expected to constitute…

This study aimed to develop a valid and reliable scale to measure individuals' and organizations' attitudes toward the use of ChatGPT, emphasizing the necessity for organizations to adapt to rapidly evolving information and technology environments. The methodology consisted of three stages. In the first stage, a 13-item draft scale was…

The purpose of this study was to examine the factor structure of vocabulary. We believe that not only is vocabulary multidimensional, but depth of vocabulary knowledge should also be assessed with multiple measures since it too, is composed of multiple aspects. Furthermore, to explore the predictive validity of the different aspects of vocabulary…

The aim of the current study was to validate the self-report version of the Rosenberg Self-Esteem Scale (RSES; Rosenberg, 1965) structure in a sample of Greek primary school students. The study was based on the original one-factor model suggested by the scale's author, as well as on the two-factor correlated model of positive and negative items.…

With the emerging trend of researching teacher identity from using qualitative approach to adopting quantitative or mixed-methods approach, it is essential and significant to develop instruments for measuring this construct. This paper reports on the development and validation of a measurement tool, the English Teacher Identity Measure (ETIM).…

Kolb's Learning Style Inventory (LSI) continues to generate a great debate among researchers, given the contradictory evidence resulting from its psychometric properties. One primary criticism focuses on the artificiality of the results derived from its internal structure because of the ipsative nature of the forced-choice format. This study seeks…

In this study (n = 5037) we further investigated the construct validity of the Georgia Brief School Climate Inventory (GBS). Despite containing ordinal items (e.g., ordered-responses), the GBS has only been examined using linear approaches. To fill this void, we employed confirmatory item factor analysis (IFA) to examine the factor structure…

Critical consciousness represents the analysis and critique of structural inequalities, the motivation and perceived capacity to effect change, and social action to redress inequity. A wave of recent instruments measuring critical consciousness have been rigorously validated. Yet, whether these measures efficiently assess different levels of…
