Research Findings: The current study explored the average levels, latent profiles, and predictors of preschoolers' cultural cognition, in a sample of 8774 preschoolers' parents in Shanghai, China. Parents with children aged 3-6 years completed measures of "Cultural Cognition Scale for Preschoolers" (CCSP) which was newly developed and…

This article presents a simple, cognitive theory of science and learning. The first section of the paper develops the theory's two main propositions: (i) A wide range of scientific activities rely heavily on one type of reasoning, hypothetical thinking, and (ii) This type of reasoning is also useful to students for learning science content. The…

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…

Occupations in science, technology, engineering, and math (STEM) are growing faster than all other fields in the United States. While this is exciting, there is concern that many of these positions will go unfilled, as students in STEM are leaving their educational pursuits at an alarming rate. The following two studies provide an in-depth…

No research has been conducted on PTSD manifestation in children with severe or moderate intellectual disability (SID; IQ 20-49) and no PTSD measurement instrument was available. This pilot explores the psychometric properties of a new diagnostic instrument to investigate trauma and to classify PTSD in children with SID. The Diagnostic Interview…

The biggest difference in statistical training from previous decades is the increased use of software. However, little research examines how software impacts learning statistics. Assessing the value of software to statistical learning demands appropriate, valid, and reliable measures. The present study expands the arsenal of tools by reporting on…

In the current article, we describe the development and validation of the Social Comparison Rumination Scale. This measured was developed as a supplement to existing social comparison measures and to enable us to determine its potential relevance to perfectionism and other personality constructs. The Social Comparison Rumination Scale (SCRS) is a…

The Theory of Successful Intelligence defines intelligence as the integrated set of abilities and competencies in specific domains needed to attain success in life. Informed by this theory, we examined the dimensionality, reliability, and validity of an augmented intelligence test, Aurora-a, a 17-subtest assessment of analytical, practical, and…

Data harmonization is an emerging approach to strategically combining data from multiple independent studies, enabling addressing new research questions that are not answerable by a single contributing study. A fundamental psychometric challenge for data harmonization is to create commensurate measures for the constructs of interest across…

Despite a call for evidence-based practice in school psychology, limited research on the topic of evidence-based assessment exists. To begin to address this gap in the research, a modified version of Jenson-Doss and Hawley's (2010) Attitudes Toward Standardized Assessment (ASA) scale was administered to 371 U.S. school psychologists. Examination…

Existing science evidence sustained that students' preferences for a learning approach (i.e., deep or surface learning) depend on several contextual variables. In this study, we used the network psychometrics perspective to investigate the interactions between the elements that define students' learning preferences. We aimed to understand which…

In scientific research on creativity, there has been considerable debate concerning the criteria by which a production can be judged more or less creative, that is, about the definition of "creativity." The most frequent definition -- the "standard" definition -- incorporates the criteria of "novelty" and…

Narcissism in social media reveals itself differently than in daily social interactions. Therefore, the present study aimed to develop a Scale of Narcissism in Social Media through the lens of the Narcissistic Admiration and Rivalry Model and to investigate its psychometric characteristics. The total sample of the study consisted of 740…

Background: This paper presents a description of the development and psychometric properties of a self-report instrument for the assessment of sexual behaviour and concerns of people with mild intellectual disabilities (SEBECOMID-S). Methods and procedures: The study included 281 people with mild intellectual disabilities. The psychometric…

Validity in psychometrics refers to the degree to which evidence and theory supports the interpretations drawn from a test, and Messick's Contemporary Validity Theory (1994) includes several facets with well-established evidence collection methods. However, there is a lack of consensus on appropriate methods of evaluating the facet of…
