Several validated adult autism symptom screening tools exist; however, there are concerns about the validity of instruments in adults who self-identify and those who have an autism diagnosis. This study evaluated the psychometric properties of the RAADS-R and RAADS-14 across gender, autism diagnosis and autistic identity, and age among a sample of…

Many universities use diagnostic tests to assess incoming students' preparedness for mathematics courses. Diagnostic test results can help students to identify topics where they need more practice and give lecturers a summary of strengths and weaknesses in their class. We demonstrate a process that can be used to make improvements to a mathematics…

Instructional leaders require timely and predictive data to guide post-pandemic systemic changes. We investigated the predictability of an observational instrument, the Rigor Appraisal, and its association with achievement and other school effectiveness measures in a sample of 53 schools in Illinois. We found that increases in the Rigor Appraisal…

Validation is needed for any newly developed model or framework because it requires several real-life applications. The investment made into e-learning in medical education is daunting, as is the expectation for a positive return on investment. The medical education domain requires data-wise implementation of e-learning as the debate continues…

The study's objectives are to i) develop a test kit to determine the ability of multiple intelligences (MI) to play basketball in high school and ii) measure a student's MI test ability in playing basketball. The method used is the development of instruments with analysis, design, development, implementation, and evaluation (ADDIE). The study…

Given that camouflaging has been suggested to contribute to delayed diagnosis and mental health problems among autistic people, validated measures of the construct are needed. This study describes the psychometric evaluation of the Swedish adaptation of the self-reported Camouflaging Autistic Traits Questionnaire (CAT-Q) in autistic (n = 100) and…

Stage fright is a natural and very common phenomenon that affects everyone who must present themselves in public. However, it has a negative impact on the health and voice emission of children and adolescents, which is why it is important to study and measure it. Unfortunately, there are no appropriate tools for examining public presentation…

The instruments for the evaluation of teachers' digital competence are abundant, however, there is still a lack of instruments oriented to the context of Special Education. In this sense, this study presents the validation process of an instrument that aims to determine the level of knowledge and digital competence of Special Education teachers…

Background: Screening is the first important step in the diagnostic process. There is strong evidence that early diagnosis and management of autism spectrum disorder (ASD) can lead to a better prognosis. The purpose of this study was to develop an Arabic version of the Chinese Checklist for Autism in Toddlers-23 (CHAT-23) to distinguish children…

This study aims to develop and validate the Principal Competency Inventory (PCI), an instrument used to assess a principal's leadership competencies that promote student learning in South Korea. An extensive review of prior work was conducted to understand the theoretical foundation related to school leadership and the competency construct of the…

Background: The Pediatric Eating Assessment Tool (PEDI-EAT-10) is a reliable and valid tool for rapid identification of dysphagia in patients aged 18 months to 18 years. Aims: To translate and adapt the PEDI-EAT-10 into the Italian language and evaluate its validity and reliability. Methods & Procedures: The translation and cross-cultural…

Traditional validation approaches fail to account for the ways oppressive systems (e.g. racism, radical nationalism) impact the test design and development process. To disrupt this legacy of white supremacy, we illustrate how justice-oriented, antiracist validation (JAV) framework can be applied to construct articulation and validation, data…

The present study developed and validated a self-regulated learning (SRL) teaching scale with a total sample of 966 preschool teachers. A pool of items was generated from literature reviews, teacher interviews, and expert reviews using Zimmerman's cyclical model of SRL. An exploratory factor analysis (N = 333) in study 1, and a confirmatory factor…

We present an investigation of the infinite sequences of numbers formed by calculating the pairwise averages of three given numbers. The problem has an interesting geometric interpretation related to the sequence of triangles with equal perimeters which tend to an equilateral triangle. Investigative activities of the problem are carried out in…

In this research we attempt to empirically validate a model - using signalling theory - that explains important antecedents and consequences of students' attitude towards internationally accredited business schools. Using a quasi-experimental design, we collected data from undergraduate students of eight countries across four scenarios. The…
