Accurate measurement of quality of life (QoL) is important for evaluation of autism services and trials of interventions. We undertook psychometric validation of the World Health Organisation measure--WHOQoL-BREF, examined construct validity of the WHO Disabilities module and developed nine additional autism-specific items (ASQoL) from extensive…

The purpose of this research is to conduct validity and reliability studies of the Scale for the Determining Social Participation for Children, developed to measure social participation skills of children aged 7-10 years. During the development of the scale, pilot schemes, validity analyzes, and reliability analyzes were conducted. In this…

In The Netherlands, the 4-Skills Scan is an instrument for physical education teachers to assess gross motor skills of elementary school children. Little is known about its reliability. Therefore, in this study the test-retest and inter-rater reliability was determined. Respectively, 624 and 557 Dutch 6- to 12-year-old children were analyzed for…

The goal of this paper is to examine the psychometric properties of a live-coded behavioral measure of joint attention, the "Attention-Following and Initiating Joint Attention Protocol" (JA Protocol), in order to assist researchers and clinicians in identifying when this measure may meet their joint attention assessment needs. Data from…

Previous research demonstrates that there is an association between effective teaching and teachers' positive psychological functioning at work. The current study explores the factor structure of the Teacher Subjective Wellbeing Questionnaire (TSWQ), which is a brief measure of two key dimensions of teachers' positive psychological functioning:…

This paper describes development and piloting of a self-report measure of teachers' readiness to implement evidence-based programs. Using mixed methods, this project proceeded in two phases. In the first phase, a program-independent self-report measure of readiness to implement was developed and piloted with N = 53 teachers. Results of…

There is a critical need to identify primary level students experiencing difficulties in mathematics to provide immediate and targeted instruction that remediates their deficits. However, most early math screening instruments focus only on the concept of number, resulting in inadequate and incomplete information for teachers to design intervention…

The conventional dichotomization of sex and gender into male and female has been found to be far from adequate in representing the amount of variance that exists within each biological sex. Expressions of gender and sexuality have gone beyond our imagination as more and more countries are beginning to allow a nonbinary/intersexed option on their…

Studies have reported gender differences in academic self-efficacy. However, how and if academic self-efficacy questionnaires are gender-biased has not been psychometrically investigated. The psychometric properties of a general version of The Physics Self-Efficacy Questionnaire -- the General Academic Self-Efficacy Scale (GASE) -- were analyzed…

Background: TIMSS 2019 is the first assessment in the TIMSS transition to a computer-based assessment system, called eTIMSS. The TIMSS 2019 Item Equivalence Study was conducted in advance of the field test in 2017 to examine the potential for mode effects on the psychometric behavior of the TIMSS mathematics and science trend items induced by the…

Over the last five years, the U.S. Department of Education (USED) is requiring states to provide more and better evidence supporting the quality and validity of their assessment and accountability systems. Notably, states are asked to explain more fully how the proposed design of their systems will provide accurate and reliable information that…

In Winter 2021-2022, the Nebraska Student-Centered Assessment System (NSCAS) assessments are administered in ELA and mathematics in Grades 3-8. In Spring 2021-2022, the NSCAS assessments are administered in English language arts (ELA) and mathematics in Grades 3-8 and in science in Grades 5 and 8. The purposes of the NSCAS assessments are to…

Over the past 14 years, AEA's Oral History Project Team (Robin Lin Miller, Jean A. King, Valerie Caracelli, and Melvin M. Mark) has conducted interviews with individuals who have made signal contributions to evaluation theory and practice, tracing their professional development and contextualizing their work within the social and political…

Research Findings: The quality of group care infants and toddlers experience relates to their concurrent and later development. Recent quality improvement initiatives point to the need for ecologically valid measures that assess the multifaceted nature of child care quality. In this article, we present the psychometric properties of an infant and…

In pedagogical contexts, concordancing is often researched in relation to a non-concordanced-based learning condition, such as dictionary-based learning, and studies have generally shown concordancing to be a valuable language learning resource, as indicated by Tom Cobb and Alex Boutlon's recent meta-analysis. However, studies framed in terms of…
