There is a critical need for high-quality clinical outcome assessments to capture the important aspects of communication ability of individuals with Angelman syndrome (AS). To center the perspective of caregivers, our team developed the novel Observer-Reported Communication Ability (ORCA) measure using best practice guidelines, with the goal of…

This article focuses on the psychometric properties and characteristics of the Assessing School Settings: Interactions of Students and Teachers (ASSIST), an observational assessment administered by trained external observers of teacher practices, classroom context, and student behaviors at the classroom level. Study 1 examines variability,…

Effective support for children with developmental disabilities or delays is dependent on the successful collaboration between families and professionals and among professionals. For years, researchers and professionals have been coaching caregivers and other professionals to implement evidence-based practices with children with disabilities.…

Describing the relative severity and change in autism symptoms is crucial for the appropriate characterization of clinical and research populations. The calibrated severity score (CSS) of the Autism Diagnostic Observation Schedule-2 (ADOS-2; Lord et al., 2012) was created to better describe autism symptom severity consistently across different…

Several observation tools evaluate teaching quality in Physical Education (PE), but none of them cover the core competencies required to comprehensively assess whether the teacher is providing teaching quality in PE. The aim of this research is to develop, validate, and test the reliability of the System for Observing Teaching Competencies in…

The present research aims to develop a valid and reliable instrument to measure teachers' observation skills. The research was conducted during the 2023-2024 academic year with 651 teachers. Data were collected through online survey methods. Expert opinion was consulted for the content and face validity of the scale in the research. Exploratory…

The main aim of this study is to build a new observational coding system for sibling interactions (Sistema de Codificación de Interacciones entre Hermanos -- SCIH) and to analyze its psychometric properties and validity. First, this study offers the first Spanish adaptation of a self-report questionnaire to measure sibling relationships that…

Reliable and valid assessment of parenting and child behaviors is critical for clinicians and researchers alike, and observational measures of parenting behaviors are often considered the gold standard for assessing parenting and parent-child interaction quality. The current study sought to evaluate the reliability and validity of the Coder…

Background/Context: For decades, practitioners, policymakers, and researchers have sought to improve the quality of early childhood education (ECE) to foster equitable experiences for young children. States are increasingly investing in evidence-based professional development programs for teachers, including practice-based coaching and early…

Effectiveness of motor interventions depends not only on learning content but also on the used teaching strategies. However, little is known regarding the application of teaching strategies in clinical practice. This study aimed to develop and assess psychometric properties of a new Dutch observational instrument to document teaching strategies:…

The observation systems being used in all 50 states require administrators to learn to accurately and reliably score their teachers' instruction using standardized observation systems. Although the literature on observation systems is growing, relatively few studies have examined the outcomes of trainings focused on developing administrators'…

Research Findings: The Quality of Care for Infants and Toddlers (QCIT) observational measure was designed to address the need for a valid and reliable measure of the quality of caregiver-child interactions that could be used in both center-based and family child care (FCC) settings, and with diverse populations. Results from a psychometric field…

High-quality early childhood education provides children with opportunities for engaged learning. Yet there are currently no classroom-level measures that focus specifically on how teachers support engagement in the classroom, a key underlying dimension of playful learning. We introduce the Playful Learning Across the Years (PLAY) observational…

The study aimed to assess the effectiveness of the Predict-Explain-Enact-Observe-Reflect (PEEOR) instructional strategy on general science students' conceptual understanding and motivation in the topic of motion and force. The research employed a pre-test post-test quasi-experimental design. The sample consisted of 107 general science summer, year…

This study examined the reliability and validity of the 13-item Classroom Observation Scale as used by teachers and non-clinically trained observers to identify children who more likely than their peers to have autism spectrum disorder in less-resourced preschools. A total of 534 children (ages 2;10 to 4;5, Mean = 3;8) from nine Chinese-language…
