A slowdown or a speedup in response times across experimental conditions can be taken as evidence of online deployment of knowledge. However, response-time difference measures are rarely evaluated on their reliability, and there is no standard practice to estimate it. In this article, we used three open data sets to explore an approach to…

Background: Valid and reliable instruments for measuring emotional development are critical for a proper diagnostic assignment in individuals with intellectual disabilities. This exploratory study examined the psychometric properties of the items on the Scale of Emotional Development--Short (SED-S). Method: The sample included 612 adults with…

As algorithmic decision making is increasingly deployed in every walk of life, many researchers have raised concerns about fairness-related bias from such algorithms. But there is little research on harnessing psychometric methods to uncover potential discriminatory bias inside decision-making algorithms. The main goal of this article is to…

This article builds upon a proiminent definition of construct validity that focuses on variation in attributes causing variation in measurement outcomes. This article synthesizes the defintion and uses Rasch measurement modeling to explicate a modified conceptualization of construct validity for assessments of developmental attributes. If…

Academic procrastination, the tendency to delay academic tasks without reasonable justification, has significant implications for students' academic performance and overall well-being. To measure this construct, numerous scales have been developed, among which the Academic Procrastination Scale (APS) has shown promise in assessing academic…

This study addresses the underexplored terrain of conceptualizing and operationalizing race and ethnicity as grouping variables in Differential Item Functioning (DIF) studies within the context of psychometric research. The investigation extends beyond the identification of DIF and delves into the theoretical framing and communication of findings…

The process of decision-making is a multifaceted cognitive endeavor encompassing various cognitive, emotional, psychological, and social processes. It empowers individuals to select from a range of alternatives. Its significance spans across age groups, impacting both adults and children, and the relevance of which goes beyond aiding learners in…

Measurement invariance (MI) is required for validly comparing latent constructs measured by multiple ordinal self-report items. Non-invariances may occur when disregarding (group differences in) an acquiescence response style (ARS; an agreeing tendency regardless of item content). If non-invariance results solely from neglecting ARS, one should…

This paper examines the psychometric properties of an existing school-based Parent Opinion Survey (POS) in order to investigate its validity as a measure of parent sentiments which may (eventually) be used to better inform the decision making of school leaders. The study focusses on the POS administered by all Victorian public schools at the time…

Researchers and practitioners in the field of second language acquisition have come to realize the importance of non-cognitive skills such as self-efficacy and self-regulation in students' learning of a second language. However, there has been limited systematic research on such measures in the second language context and the validity and…

To revise the Parental Autonomy Support Scale (PASS) and to validate its psychometric properties in Chinese college students, this study recruited 738 Chinese college students, with 72 of them retested four weeks later. The Parental Psychological Control Scale (PPCS) and the Self-Esteem Scale (RSES) were used to evaluate the validity of the PASS.…

Objective: This study examines the validity of the ASRS-5 as a new screening tool for ADHD and evaluates its proposed screening cut-off in a general population context. Method: A nationally representative sample of 2,002 individuals aged 18 to 80 years was surveyed using the ASRS-5, with complete data obtained from 714 participants. Psychometric…

Tools to measure autism knowledge are needed to assess levels of understanding within particular groups of people and to evaluate whether awareness-raising campaigns or interventions lead to improvements in understanding. Several such measures are in circulation, but, to our knowledge, there are no psychometrically-validated questionnaires that…

The Ages and Stages Questionnaires: Social-Emotional, Second Edition (ASQ:SE-2) has been translated into Traditional Chinese (ASQ:SE-2-TC) in Taiwan. This study investigated whether the ASQ:SE-2-TC is also suitable for use in Malaysian Chinese families, and if any cultural differences are presented in ASQ:SE-2-TC items. This study analyzed the…

Recently, psychometricians and researchers have voiced their concern over the exploration of language test items in light of Messick's validation framework. Validity has been central to test development and use; however, it has not received due attention in language tests having grave consequences for test takers. The present study sought to…
