Background: The study focuses on the need to optimise assessment scales for support needs in individuals with intellectual and developmental disabilities. Current scales are often lengthy and redundant, leading to exhaustion and response burden. The goal is to use machine learning techniques, specifically item-reduction methods and selection…

Although the original long version of the Hewitt Multidimensional Perfectionism Scale (HMPS) has been translated and validated in a Spanish population, no study to date has examined the psychometric properties of a short version of the HMPS with a Spanish-speaking sample. For this reason, the aim of this study is to analyze the psychometric…

Although conceptual assessment tests are commonly administered at the beginning and end of a semester, this pre-post approach has inherent limitations. Specifically, education researchers and instructors have limited ability to observe the progression of students' conceptual understanding throughout the course. Furthermore, instructors are limited…

Back random responding (BRR) behavior is one of the commonly observed careless response behaviors. Accurately detecting BRR behavior can improve test validities. Yu and Cheng (2019) showed that the change point analysis (CPA) procedure based on weighted residual (CPA-WR) performed well in detecting BRR. Compared with the CPA procedure, the…

Mental imagery is a vital cognitive skill that significantly influences how reality is perceived while creating art. Its multifaceted nature reveals various dimensions of creative expression, amplifying the inherent complexities of measuring it. This study aimed to shorten the Mental Imagery Scale in Artistic Creativity (MISAC) via the Ant Colony…

A short form of the 60-item computer-based orthographic processing assessment (long-form COPA or COPA-LF) was developed. The COPA-LF consists of five skills, including rapid perception, access, differentiation, correction, and arrangement. Thirty items from the COPA-LF were selected for the short-form COPA (COPA-SF) based on cognitive diagnostic…

Lexical diversity (LD) is an important indicator of second language lexical development. Much research has investigated LD indices, with a focus on learners of English. However, further research is needed in languages that are typologically distinct from English, such as Korean. In this study, we evaluated the reliability and validity of LD…

Academic and occupational success requires social intelligence, the ability to comprehend, and manage interpersonal connections. This research aims to assess and improve the Tromsø Social Intelligence Scale (TSIS) for Peruvian university students, focusing on cultural adaptability, reliability, and validity. Participants included 973 university…

Academic motivation is important to students' mental health and performance. One established measure is the Academic Motivation Scale (AMS), comprising 28 items. AMS assesses intrinsic motivation, extrinsic motivation, and amotivation, which are further categorised into seven subscales. One weakness of AMS is its length. In this study, we…

To ensure the validity of the tests is to check that all items have similar results across different groups of individuals. However, differential item functioning (DIF) occurs when the results of individuals with equal ability levels from different groups differ from each other on the same test item. Based on Item Response Theory and Classic Test…

The purpose of this study was to investigate the validity evidence for the use of the 19-item and 20-item short forms of the MUSIC Model of Academic Motivation Inventory (College Student version) with undergraduate students. These shorter forms of the MUSIC Inventory could be beneficial to teachers and researchers. Our analysis included inventory…

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…

Competence-based test development (CbTD) is a novel method for constructing tests that are as informative as possible about the competence state (the set of skills an individual masters) underlying the item responses. If desired, the tests can also be minimal, meaning that no item can be eliminated without reducing their informativeness. To…

This article provides a detailed review of the Computer-based English Listening Speaking Test (CELST) used in Guangdong, China, as part of the National Matriculation English Test (NMET) to assess students' English proficiency. The CELST measures listening and speaking skills as outlined in the "English Curriculum for Senior Middle…

Pearson Test of English Academic (PTE Academic), a high-stakes English language proficiency test, underwent substantial revisions in 2021. The test duration was reduced from 3 h to 2 h by reducing specific task numbers and sections. This study investigates the impact of these changes on teachers' perceptions and teaching practices, areas…
