This study argues that readability formulas should be used as one measure of linguistic equivalence when adapting psychometric scales from one language to another. Assuming that the psychological structure being measured was not changed, it was observed that calculated readability levels and interpretations were different for two different…

The United Nations 2030 Agenda for Sustainable Development and, in particular, its Sustainable Development Goal no. 4, underline the relevance of quality education that translates into long-term benefits for all learners. This article reports findings of a collaborative research study that piloted an inclusive practice index to investigate…

The phenomenon of statistics anxiety, prevalent particularly among students engaged in non-mathematical disciplines such as the social sciences, has been linked to a multitude of detrimental outcomes. Over time, several instruments have been developed to measure this construct; however, a comprehensive analysis of these instruments and an adequate…

This paper reports on a multiyear program of international collaborative research delivered with the aim of conceptualising, validating and prototyping rubrics for evaluating and reporting university activities and outcomes relevant to the UN SDGs. The paper sets foundations by building on earlier analysis of research on university engagement with…

Measurement invariance (MI) is a psychometric property of an instrument indicating the degree to which scores from an instrument are comparable across groups. In recent years, there has been a marked uptick in publications using MI in intellectual and developmental disability (IDD) samples. Our goal here is to provide an overview of why MI is…

The purpose of the study was to develop the Teachers' Mental Toughness Questionnaire (TMTQ). The questionnaire was developed in six stages: item generation, content validity, exploratory factor analysis, reliability tests, convergent validity tests, and discriminant validity. The factor analysis indicates that it measures six factors: team,…

If psychometrics has long concerned itself with validity, reliability, and fairness, then what could psychometrics learn from the cybernetic theories of AI? Through engagement with Burstein's (2023) Responsible AI Standards, this paper unpacks some paradigmatic differences between psychometrics and cybernetics, points to how recursivity and…

This study aimed to review the scientific literature on etiopathogenic factors of savant syndrome associated with autism spectrum disorder (ASD). Searches were performed in the following databases: Medical Literature Analysis and Retrieval System Online, Embase, Scopus, Science Direct, Cochrane Library, Latin America and Caribbean Center on Health…

In this secondary analysis of a previously conducted systematic review, we analyze social validity assessments in intervention research for transition-age autistic youth. Social validity is concerned with the acceptability of the intervention goals, the acceptability and feasibility of the intervention procedures, and the perceived importance of…

Advancements in education and the perceived necessary educational outcomes require advanced psychometric approaches. This is particularly true when we consider noncognitive assessments -- assessments that aim to measure soft skills, otherwise untested in classrooms today. Noncognitive skills have gained traction in recent years due to the…

Background: Content validity is a key measurement property that should be considered when selecting or reviewing a patient-reported outcome measure (PROM). In the field of communication disorders, there are several PROMs available, most of which are disease specific. It is unknown what the quality of the content validity of these PROMs is. Aims:…

Despite the evolution of the grit conceptualization over the years, the psychometric validity of scales and construct structure remain unclear. Consequently, this study aims to provide new evidence that broadens the current understanding of the grit's dimensional nature in the Spanish population by examining the psychometric properties of the…

Parallel analysis has been considered one of the most accurate methods for determining the number of factors in factor analysis. One major advantage of parallel analysis over traditional factor retention methods (e.g., Kaiser's rule) is that it addresses the sampling variability of eigenvalues obtained from the identity matrix, representing the…

Purpose: To make early detection of individuals with autism spectrum disorder (ASD), caregiver-report instruments remain an efficient and adaptable option for the preliminary assessment. This study aimed to compare the psychometric properties of the Clancy Autism Behavior Scale (CABS) and Autism Behavior Checklist (ABC) as screening tools for ASD…

This study describes the development of the science, technology, engineering, and mathematics (STEM) Scale, intended to assess parental attitudes toward school programs designed to deliver STEM, and evaluates its psychometric properties. The study group included 400 parents of students (138 males and 262 females) enrolled in STEM programs…
