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…

Organization, time management, and planning (OTMP) skills are behavioral manifestations of executive functioning linked to academic outcomes. Interventions to improve OTMP skills have shown favorable outcomes. The Children's Organizational Skills Scale parent and teacher forms (COSS-P, COSS-T) are widely used for assessing OTMP skills, but there…

This study tested the factor structure, reliability, and criterion validity of the Academic Encouragement Scale (AES) in 690 university students in China. The AES displayed good internal consistency and test--retest reliability. The data provided evidence supporting a two-factor structure: challenge focused encouragement (CFE) and potential…

The purpose of this study was to develop a theoretically-driven instrument of achievement motivation and determine its validation. The Achievement Motivation Measure (AMM) is closely aligned with Atkinson and McClelland's (1948, 1953, 1961) theoretical constructs of achievement thoughts and behaviours. Confirmatory and exploratory factor analysis…

The structure of academic self-concept (ASC) is assumed to be multidimensional and hierarchical. This methodological review considers the most central models depicting the structure of ASC: a higher-order factor model, the Marsh/Shavelson model, the nested Marsh/Shavelson model, a bifactor representation based on exploratory structural equation…

This study analyzed the psychometric properties of the Italian translation of both the Short Almost Perfect Scale (SAPS) and the Short Multidimensional Perfectionism Scale (SMPS), and the academic implications of perfectionism on 414 Italian college students aged between 18 and 58 years. Results revealed some limitations with the SAPS factor…

The objectives were to examine the factorial structure of the Academic Procrastination Scale-Short Form (APS-S) and the measurement invariance across gender and educational levels, to determine possible differences in procrastination across gender, educational levels, and grades. The sample was formed of 1486 Spanish primary and secondary school…

The aim of the study is to develop a scale named Classroom Life Perception Scale (CLPS) for determining the classroom life perceptions of the students toward lessons. The proposal scale, composed of 44 items, was applied to 2 study groups. The group of Exploratory Factor Analysis that aims to determine the psychometric properties especially the…

This study aimed to develop and evaluate a new parent-report measure to assess primary schoolchildren's academic behaviors in the home context. We developed the Academic Behavior Scale (ABS) and administered it to Chinese parents of primary schoolers along with other measures. Six hundred and forty-five parents and 170 primary schoolchildren in…

The current study aimed to adopt and assess the psychometric properties and measurement invariance of Grit-S among Omani and American students (N = 487) using Exploratory Factor Analysis (EFA) and Multi-Group Confirmatory Factor Analysis (CFA). The scale's construct validity was estimated by investigating its associations with achievement goal…

The purpose of this study was to explore the psychometric properties of an Arabic translation of the Gifted Rating Scales-School Form (GRS-S) on a national sample of 907 students from Cycle 1 (Grades 1 to 4) and Cycle 2 (Grades 5 to 10) from five governorates in Oman (Muscat, Dhofar, Al-Batinah North, Al-Sharqiyah South, and Al-Dhahira). The…

There is growing interest in improving and assessing teachers' use of culturally responsive practices (CRP) in the classroom, yet relatively few research-based approaches exist to address these measurement gaps. This article presents findings on the psychometric properties of a newly developed classroom observation measure of CRP, called the CARES…

The Academic Competence Evaluation Scales (ACES; DiPerna and Elliott in School Psychol Rev 31(3):293, 2002) is a 73-item teacher rating scale that assesses academic skills and enablers. The ACES Short Form (ASF) is a newly extracted 32-item short form of the ACES that has promising psychometric properties (Anthony and DiPerna in School Psychol Q…

In this study, we examined the factor structure, reliability, and external validity of scores from the Comprehensive Test of Nonverbal Intelligence-Second Edition (CTONI-2) using an independent sample of young adults currently enrolled in a postsecondary institution. Although the subtests appear to be measuring general intelligence, the aggregate…
