This empirical investigation examined the cross-cultural usefulness of a measure of creative potential, namely the short form of the Runco Ideational Behavior Scale (RIBS). The RIBS has been used in several investigations and existing data show it to be a reliable criterion measure, usually with a two-factor structure. Scores from the RIBS…

This study aimed to develop a comprehensive tool to assess underachievement in gifted students, incorporating input from parents, teachers, and students themselves. A total of 285 participants, including 95 gifted students, their parents, and teachers, were involved in the study. The results have revealed a four-factor structure for the Gifted…

Within the organizational field, emotional intelligence is linked to socially competent behaviors, which allow the development of labor and organizational abilities necessary for professional development. Thus, in workers, emotional intelligence is related to a wide range of organizational variables. The purpose of the present study was to…

Background/Context: Previous research in educational assessment has consistently emphasized the importance of reliability as a cornerstone of test quality. Traditional measures of reliability, such as test-retest and split-half reliability, offer a broad view of how internally consistent a measure is but overlook the variability in this internal…

Raven's Standard Progressive Matrices (Raven 1941) is a widely used 60-item long measure of general mental ability. It was recently suggested that, for situations where taking this test is too time consuming, a shorter version, comprised of only the last series of the Standard Progressive Matrices (Myszkowski and Storme 2018) could be used, while…

In this article, we reviewed how intelligence tests were developed and normed, with a careful eye to underserved groups. Based on state recommendations, five group-administered and five individually-administered tests were reviewed for demographics; invariance testing; validity and reliability reporting; and gifted identification suitability. We…

The scientific approach to the study of creative problem-solving has shifted from using classic insight problems (e.g., the "Nine-dots" problem), toward sets of problems that have more robust psychometric properties, such as the Remote Associate Test (RAT). Because it is homogeneous, compact, quickly solvable, and easy to score, the RAT…

This study aimed to investigate the psychometric properties of the Wechsler-4 Intelligence Scale who are deaf with Mild Intellectual Disability. Descriptive survey method was used. The sample included (174) deaf students in Jordan, ranging in age from (6-16.11) years. The scale was also applied in sign language. Validity indicators were found…

Assessment of individuals on the autism spectrum often includes a measure of nonverbal IQ. One such measure is the Raven's Standard Progressive Matrices (RSPM). For large research studies with participants distributed nationally it is desirable for assessments to be available online. Because time is a premium, it is ideal that the measure produces…

Figural matrices tasks are one of the most prominent item formats used in intelligence tests, and their relevance for the assessment of cognitive abilities is unquestionable. However, despite endeavors of the open science movement to make scientific research accessible on all levels, there is a lack of royalty-free figural matrices tests. The Open…

The Student Oral Language Observation Matrix (SOLOM) is an assessment of oral language skills. The aim of this study was to examine psychometric properties of the SOLOM for preschoolers through (a) use of internal consistency methods to assess the reliability of the scores from the SOLOM and (b) examination of criterion-related validity by…

Introduction: Intellectual disability is a key subject in all mental healthcare institutions, including the forensic mental health services. The Screener for Intelligence and Learning Disability (SCIL) is designed to screen for intellectual disability in forensic populations. So far, this assessment method is only validated in "detention fit…

The authors evaluated measurement-level, factor-level, item-level, and scale-level revisions to the "Gifted Rating Scales-School Form" (GRS-S). Measurement-level considerations tested the extent to which treating the Likert-type scale rating as categorical or continuous produced different fit across unidimensional, correlated trait, and…

Assessing job applicants' general mental ability online poses psychometric challenges due to the necessity of having brief but accurate tests. Recent research (Myszkowski & Storme, 2018) suggests that recovering distractor information through Nested Logit Models (NLM; Suh & Bolt, 2010) increases the reliability of ability estimates in…

This article aims to investigate the reliability and validity of the Trait Emotional Intelligence Questionnaire-Adolescent Short Form (TEIQue-ASF) score in a sample of 440 Greek adolescents. The instrument's score demonstrated good internal consistency and was significantly correlated with core self-evaluations as well with somatic complaints,…
