The goal of this paper is to find better ways to estimate the internal consistency reliability of scores on tests with a specific type of design that are often encountered in practice: tests with constructed-response items clustered into sections that are not parallel or tau-equivalent, and one of the sections has only one item. To estimate the…

Connectedness to nature influences the well-being and health of individuals, communities, and the planet. Although many validated scales exist, none includes the three fundamental aspects of any attitude: the affective, behavioural, and cognitive components. The study's main objective was to develop and validate an integral tool, the ABC e…

At present, there are no brief, freely-available, informant-report measures that evaluate key challenging behaviors relevant to youth with autism spectrum disorder (ASD) or other developmental disabilities (DD). This paper describes the development, refinement, and initial psychometric evaluation of a new 18-item measure, the Open-Source…

Awareness of informational text structures is related to reading comprehension and varies according to characteristics of readers and texts. The purpose of this study was to develop and refine a measure of text structure awareness, the Text Structure Identification Test (TSIT), by investigating its internal consistency reliability and construct…

The Video Engagement Scale (VES) is a quality indicator to assess engagement in experimental video-vignette studies, but its measurement properties warrant improvement. Data from previous studies were combined (N = 2676) and split into three subsamples for a stepped analytical approach. We tested construct validity, criterion validity,…

This work is intended to develop a measuring tool for determining teacher perception of informal relationships. The pool of items created by researchers through a literature review has been presented with expert assessment of the validity of the content, face, and meaning, and a draft scale has been created by making necessary revisions to the…

Purpose: This study reports on the development, validation and measurement invariance of the Multicultural Competency Scale (MCS) for pre-service teachers. Research Methods: Data from 640 pre-service teachers were collected for two studies. After data screening procedures 628 responses were left. The data were divided into two sets for exploratory…

The underrepresentation of students from low-income families and of culturally diverse students is a longstanding and pervasive problem in the field of gifted education. Teachers play an important role in equitably identifying and serving students in gifted education; therefore, the Having Opportunities Promotes Excellence (HOPE) Scale was used in…

The purpose of this study was to develop a scale measuring attitudes toward women's working. In line with this main purpose, two studies were conducted to develop the tool and investigate its psychometric properties in two different samples. The study 1 started with generating item pool, conducting exploratory factor analysis to identify…

To examine reliability, validity, factor structure, and measurement invariance (i.e., configural, metric, and scalar invariance) of the Japanese Conners' Adult attention deficit hyperactivity disorder (ADHD) Rating Scales (CAARS), Japanese nonclinical adults (N = 786) completed the CAARS Self-Report (CAARS-S). Each participant was also rated by…

The "Motor-Free Visual Perception Test-fourth edition" (MVPT-4) is a revised version of the "Motor-Free Visual Perception Test-third edition." The MVPT-4 is used to assess the visual-perceptual ability of individuals aged 4.0 through 80+ years via a series of visual-perceptual tasks that do not require a motor response. Test…

The aim of this study was to apply the Rasch model to an analysis of the psychometric properties of the Peabody Picture Vocabulary Test--III Form A (PPVT--IIIA) items with struggling adult readers. The PPVT--IIIA was administered to 229 African American adults whose isolated word reading skills were between third and fifth grades. Conformity of…

The reliability, content validity, and construct validity were compared for two test formats in a public examination used to assess a secondary school geography course. The 11-item geography portion of the Intermediate Certificate Examination (essay examination) was administered in June 1987 to 400 secondary school students in Ireland who also…

The Elementary School Success Profile (ESSP) is a multidimensional instrument for school-based practitioners that assesses the social environmental domains of neighborhood, school, friends, and family, as well as the well-being, behavior, and school performance of students in the third, fourth, and fifth grade. This article presents the…
