The current study assessed reliability and validity evidence of the shortened Swedish Mathematics Anxiety Rating Scale--Elementary (MARS-E), using data from three time points. After initial pilot tests, a total of 429 students participated in the study, completing the MARS-E twice during grade 4 and once during grade 5. Confirmatory factor…

This study examines the convergent validity of the Physical Activity Questionnaire for Children (PAQ-C) for assessing moderate-to-vigorous and total physical activity (PA) in school children. 430 participants (51.6% girls) aged 9-12 years provided valid accelerometer data (wGT3X-BT) and completed the PAQ-C. Convergent validity was assessed using…

The aim of the study was to explore same-sex and opposite-sex friendship functions among 12 to 13- and 16 to 17-year-old Hungarian adolescents (n = 304). To explore perceptions of friendship functions, the McGill Friendship Questionnaire (MFQ, 30 items, 6 factors: stimulating companionship, help, intimacy, reliable alliance, self-validation,…

This study provides a thorough psychometric evaluation of construct and criterion validity and measurement invariance of the promising Florence Bullying-Victimization Scales (FBVS). A special focus was devoted to the concurrent criterion validity of the victimization scale with regard to well-being and social self-efficacy. Exploratory and…

Although reading strategy use can be measured using different methods, self-report measures are particularly cost-effective in educational settings. The main goal of this study was to investigate the psychometric properties of the items of the Reading Strategy Use Scale (RSU), using the Rasch Rating Scale Model. Although the RSU has already been…

The current study examined the measurement invariance (MI) of the Georgia Brief School Climate Inventory (GaBSCI) with a rural and predominately Hispanic sample (N = 413). The results present support for the one-factor structure and MI of the GaBSCI across genders and Spanish-speaking groups, but only partially for different school levels.

More than a decade after two comprehensive examinations of the technical properties of the ClassMaps Survey (CMS), this study reexamined the structure and internal consistency of the scale and, for the first time, examined its measurement invariance across gender and school levels. Participants were 1,083 elementary and middle level students from…

One of the major purposes of this study is to investigate the potential impact of gender and information and computer technology (ICT) resources on students' computational thinking (CT) competencies. To this end, the Computational Thinking Test for Junior High Students (CTT-JH) was developed and validated. Research participants included 437 junior…

This research developed and psychometrically tested the Sport Education Scale, a measure of students' perceptions of the structural features of a Sport Education season. In the first study (N = 277 students), a pool of 28 items was developed, and an exploratory factor analysis found a 7-factor solution. In the second study (N = 656 students), a…

The study aimed to develop and evaluate the psychometrical properties of a new brief measure of gender stereotyping career attitudes. Participants were 222 early and 196 middle adolescents from Croatia. The Vocational Gender Stereotype Attitudes Scale (VGSA) consists of 12 items that represent masculine, feminine and gender-balanced activities…

Background: Technically sound measures are necessary for accurately identifying youth at risk for depression, but many studies rely on classical test theory metrics or adult samples to evaluate measures. This study examined the use of the PHQ-8, a common and freely available pediatric depression screener, in an adolescent sample using item…

Writing motivation is a multidimensional construct that has been demonstrated to be of great importance in writing performance and growth. Yet, much of the extant research has failed to examine the nuances of the various dimensions of writing motivation--in particular, task competency beliefs--and has neglected to investigate how the various…

The current study investigates the reliability and validity of a Saudi-translated version of the GRS-S on a sample of 1,200 Saudi elementary and middle school students. Results showed that the reliability and validity of all six of the GRS-P subscales were high. The results revealed that there were no differences between males and females in all…

Digital literacy is essential for scientific literacy in a digital world. Although the NGSS Practices include many activities that require digital literacy, most studies have examined digital literacy from a generic perspective rather than a curricular context. This study aimed to develop a self-report tool to measure elements of digital literacy…
