Given the importance of fostering students' interest as a goal of physics education in meeting international science standards, empirical support for the theoretical description of the interest construct is essential. Empirical studies require the use of psychometrically sound measurement instruments. This study developed an instrument to measure…

The Fear of COVID-19 Familial Infection (FCFI) scale examines parents' fear levels of infecting their families with COVID-19. Principle component analysis and confirmatory factor analysis in a sample of parents (N = 582) revealed two factors: Fear of infecting others and Others' Fear of being infected by me.

Rasch and classification analyses on a field-test version of the third edition of the Assessment, Evaluation, and Programming System (AEPS-3), a curriculum-based assessment used to assess young children birth to age 6 years, were conducted. First, an evaluation of the psychometric properties of data from each developmental area of an AEPS-3…

Given the heterogeneity of Attention-Deficit Hyperactivity Disorder (ADHD), there is a constant need for proper diagnosis, employing more accurate, efficient, patient-friendly, and clinician-friendly tools. We developed a Greek version of the National Institute for Children's Health Quality (NICHQ) Vanderbilt ADHD Diagnostic Parent Rating Scale…

Few juvenile justice group experimental and quasi-experimental literacy-focused studies document fidelity of implementation (FOI). Even fewer of those studies consider the psychometric properties of the FOI instrumentation used. The aim of this study was to examine the psychometric properties of a brief FOI instrument used with English language…

The ability to work in a team is currently one of the most demanded competencies of professionals and, therefore, constitutes one of the key transversal aspects to be targeted by educational systems. This is especially important at stages prior to job insertion. The aim of the present study was to validate a scale measuring perceptions of teamwork…

This paper describes the development of two nomination scales designed to measure parents' and teachers' perceptions of high academic potential among young children, and how the scores correlate with assessed high potential. Parents and teachers of 243 children (49% girls) taking part in the research project 'Skoleklar' responded to written…

Research Findings: In this study, we tested whether it is possible to reliably evaluate the quality of interactions between early childhood educators and children using a thin-slice coding approach. Ninety-seven early childhood educators were videotaped for two five-minute intervals: one mealtime observation and one standardized activity. Videos…

The Wechsler Individual Achievement Test (WIAT-4) is the latest iteration of a popular instrument that psychologists employ to assess academic achievement. The WIAT-4 authors make both pragmatic and measurement claims about the instrument. The pragmatic claims involve being useful for identifying individuals in certain academic achievement-related…

The creation of psychometrically sound assessments of teacher well-being is critical given the alarmingly high rates of teacher burnout reported among U.S. educators. The present study sought to address this need by developing the Measures of Stressors and Supports for Teachers (MOST), a teacher-report questionnaire designed to assess ecological…

Background: Creating a holistic picture of children and youth who suffer from acquired aphasia or another (developmental) language disorders is very difficult due to missing diagnostic instruments covering participation. Szenario-Kids is a new diagnostic instrument to measure multimodal communication abilities in everyday life situations of…

This research examines psychometric properties of the 10-item Perceived Academic Social Influence Scale (PASIS) across gender groups with samples from Finland and Taiwan (Total N = 4727, 50.2% female adolescents). Results of composite scores, factor loadings, item-total correlations, and values of square root of Average Variance Extracted (AVE)…

In order to assess the accuracy and validity of proficiency diagnostic tests in Second Language (L2), specifically regarding the linguistic (orthographic, semantic, syntactic, lexical) and cognitive (verbal reasoning, lexical decision) components for the immigrant population in Portugal, a study of cut-off points of 6 tests was conducted. This…

There has been substantial scholarly attention given to teachers' functioning over the past two decades. Much of this attention has been precipitated by accounts of increasing teacher burnout and attrition from the profession. Central to this scholarly focus has been the construct of teacher self-efficacy, which has been shown to be a predictor of…

Categorical data become increasingly ubiquitous in the modern big data era. In this dissertation, we propose novel statistical learning and inference methods for large-scale categorical data, focusing on latent variable models and their applications to psychometrics. In psychometric assessments, the subjects' underlying aptitude often cannot be…
