Purpose: The purposes of this study were (a) to introduce "language access profiles" as a viable alternative construct to "communication mode" for describing experience with language input during early childhood for deaf and hard-of-hearing (DHH) children; (b) to describe the development of a new tool for measuring DHH…

Purpose: This study provided reference data and examined psychometric properties for clausal density (CD; i.e., number of clauses per utterance) in children between ages 4 and 9 years from the database of the Edmonton Narrative Norms Instrument (ENNI). Method: Participants in the ENNI database included 300 children with typical language (TL) and…

Evaluation of music performance in competitive contexts often produces discrepancies between the expert judges. These discrepancies can be reduced by using appropriate rubrics that minimise the differences between judges. The objective of this study was the design and validation of an analytical evaluation rubric, which would allow the most…

Can non-clinicians spot preschoolers likely to have autism spectrum disorder by observing their everyday peer interaction? We set out to develop a screening tool that capitalizes on peer interaction as a naturalistic "stress test" to identify children more likely than their peers to have autism spectrum disorder. A total of 304 3- to…

We evaluated the psychometric properties of the Classroom Practices Survey--Revised (CPS-R) when used with students achieving at low, average, and high levels. A total of 739 teachers completed CPS-R for students in their classrooms. Results showed improvement in the reliability of CPS-R across all achievement levels when compared with its…

Background: Motivation is critical for supporting persistence and achievement in science, technology, engineering, and mathematics (STEM) disciplines. In this study, we focus on the assessment of mathematics motivation among secondary school students. We provide validity and reliability evidence for the Mathematics Motivation Questionnaire…

The aim of study is to develop a valid and reliable scale in order to determine problems encountered by teachers in distance education process. Survey research method was used in the study. The sample of research consists of 411 teachers working in different branches and recitation with distance education at the 2019-2020 academic years. In this…

Computer adaptive testing is intended to make assessment more reliable by tailoring the difficulty of the questions a student has to answer to their level of ability. Most commonly, this benefit is used to justify the length of tests being shortened whilst retaining the reliability of a longer, non-adaptive test. Improvements due to adaptive…

Two studies were conducted to examine the use of the Taiwanese version of the Screening Tool for Autism in Two-Year-Olds for detecting autism spectrum disorder in toddlers aged 18-24 months. Study 1 used receiver operating characteristics to select a cutoff score for the Taiwanese version of the Screening Tool for Autism in Two-Year-Olds. It…

The present study aimed to develop an indigenous measure of learning styles for e-learners in Pakistan and to establish its psychometric properties. The objectives of the study were attained via three studies. First, the items for the development of the Learning Style Scale for e-Learners (e-LSS) were generated empirically based on a 5-point…

Although 70% of autistic children and young people meet criteria for co-occurring psychiatric conditions, there are few screening measures specifically for autistic individuals. We describe the development and validation of the Assessment of Concerning Behavior (ACB), an instrument co-developed with the autistic community to assess mental health…

Background: To encourage self-determination and address health disparities among persons with intellectual and developmental disabilities, clinicians and researchers rely on self-reported measures like health-related quality of life (HRQoL). This study evaluated the psychometric properties of a theory-driven self-reported HRQoL measure for adults…

We report findings of two validation studies of the Student Risk Screening Scale for Early Childhood (SRSS-EC). Although previous exploratory inquiry suggested a two-factor solution, results of Study 1 conducted with 274 preschool-age youth suggested mixed support for a two-factor model, with only one fit index suggesting an adequate fit…

Purpose: The purpose of this research was to develop and validate a robust scale, based on the community capital framework, to provide an empirical measure of community perceptions. Design/methodology/approach: The proposed measure was completed by a sample of Georgia citizens (n = 3374) representing a diverse cross-section of community…

The What Is Happening In this Class? (WIHIC) questionnaire is a multidimensional measure for assessing the classroom learning environment based on student perspectives. The purpose of this study was to validate an Indonesian version of WIHIC and to assess the instrument's psychometric properties by using confirmatory factor analysis (CFA) and the…
