Purpose: Intentional communication acts, or purposefully directed vocalizations and gestures, are particularly difficult for infants at elevated likelihood for eventual diagnosis of autism. The ability to measure and track intentional communication in infancy thus has the potential to aid early identification and intervention efforts. This study…

This study aimed to adapt the Plurilingual and Pluricultural Competence scale (PPC) to the Russian-speaking population and to assess its psychometric properties. Five hundred and sixty-four undergraduate students from Western, Central, and Caucasian regions of Russia and Kazakhstan participated in the study. Internal consistency, factorial,…

This report summarizes some of the evidence supporting interpretations of scores from the enhanced ACT, focusing on reliability, concurrent validity, predictive validity, and score comparability. The authors argue that the evidence presented in this report supports the interpretation of scores from the enhanced ACT as measures of high school…

In March of 2025, brightwheel, a San Francisco-based educational technology company, partnered with the Center for Research and Reform in Education (CRRE) at Johns Hopkins University to test brightwheel's product, the Experience Assessment. The assessment was designed to provide early childhood educators with an objective and systematic way to…

Statistical reasoning is a crucial mathematical competency that students often lack. While there have been studies on the use of Android teaching materials in statistics learning, few have focused on statistical reasoning using comic media. This study aimed to develop mobile Android-based teaching materials called StatCom to enhance students'…

The DAATS (Dispositions Assessments Aligned with Teacher Standards) battery is a series of five instruments of different item types that measure teachers' consistency with the critical dispositions embedded in the InTASC Standards. The purpose of this study was to continue a 20-year research project on the development and implementation of…

Self-efficacy and anatomical knowledge have been shown to be important in the development of medical students. Validated instruments designed to measure the construct of anatomical self-efficacy during the clinical years of medical school are limited. In this study, the Anatomical Self-Efficacy Instrument for Clinical Clerkships (ASEI-CC) was…

Scales assessing stressor exposure often fail to demonstrate adequate psychometric qualities, demonstrating low interitem reliability or complex factor structures, as would be expected, given that the majority of stressors are independent events. However, in large-scale mass crisis events, the stressors may be highly interrelated, indicating…

The research and practice of social scientists who work in a myriad of different specialty areas involve developing and validating scores on instruments as well as evaluating the psychometric properties of existing instrumentation for use with research participants. In this article, the author introduces The MEASURE Approach to instrument…

Purpose: The aim of this study was to use the Daily Phonotrauma Index (DPI) to quantify group-based changes in the daily voice use of patients with phonotraumatic vocal hyperfunction (PVH) after receiving voice therapy as the sole treatment. This is part of an ongoing effort to validate an updated theoretical framework for PVH. Method: A…

In this article, we develop the revised and short versions of the pseudoscientific belief scale through two empirical studies (N = 4154). This revision is motivated by the excessive length of the scale, as well as by consistent observations of poor item loadings across several studies. Exploratory factor analysis in Study 1 revealed 11 dispensable…

The present investigation aims to test the validity of scores on the math homework purpose scale (MHPS) for high school students. Factorial results found that the MHPS contained three subscales: academic purpose, self-regulatory purpose, and approval-seeking purpose. Furthermore, the MHPS had a sufficient level of measurement and latent factor…

Background: The ability to navigate obstacles and embrace iteration following failure is a hallmark of a scientific disposition and is hypothesized to increase students' persistence in science, technology, engineering, and mathematics (STEM). However, this ability is often not explicitly explored or addressed by STEM instructors. Recent collective…

Background: Self-assessments for adults who stutter are recommended as a primary evaluation tool for including their views on stuttering. Evaluating adults who stutter with self-assessment scales is important. However, there is no tool in the Turkish literature that provides this measurement. Aims: To develop the Turkish version of The Wright and…

Competence development and measurement are of great interest to vocational education and training (VET). Although there are many instruments available for measuring competence in diverse settings, in many cases, the completed steps of validation are neither documented nor made transparent in a comprehensible manner. Understanding what an…
