The Abbreviated Math Anxiety Scale (AMAS) is commonly used to compare groups on math anxiety. Group comparisons should however be preceded by a demonstration of metric and scalar measurement invariance, which is currently only available for undergraduate students in the USA. This study tested for metric and scalar measurement invariance of AMAS…

In the present study the construct inquiry of mind explored and an instrument to measure it is proposed. Using three different samples, explorative and confirmative factor analyses were performed, resulting in three empirical dimensions that correspond to the three theoretical dimensions: 1) 'value deep understanding,' 2) 'reserve judgment and…

Research has highlighted potential differences in the phenotypic and clinical presentation of autism spectrum conditions across sex. Furthermore, the measures utilised to evaluate autism spectrum conditions may be biased towards the male autism phenotype. It is important to determine whether these instruments measure the autism phenotype…

Summer enrichment and residential programs can provide gifted students with positive social interactions and challenging curricula. However, little research has focused on gifted students' perceptions of the learning environment in such programs. This research project evaluated the psychometric properties and practical applications of the…

Despite its popularity, the factorial structure of the Psychological Sense of School Membership (PSSM) Questionnaire remains controversial. The current study set out to clarify its structure across different cultural contexts. The study was carried out among 1,928 adolescents aged 11 to 20 years in the Netherlands, Kenya, Indonesia, and Spain.…

Purpose: This study examined the construct validity and reliability of a therapeutic alliance measure (Children's Alliance Questionnaire [CAQ]) for children with psychosocial and/or behavioral problems, receiving therapeutic residential care or day care in the Netherlands. Methods: Confirmatory factor analysis of a one-factor model ''therapeutic…

This article argues that strong interrelations between methodological and theoretical advances exist. Progress in, especially comparative, methods may have important impacts on theory evaluation. By using the example of the "Varieties of Capitalism" approach and an international comparison of higher education systems, it can be shown…

The aims of the present study were (1) to identify to what extent school motivation and school commitment contributed to the explanation of students' academic achievement in addition to the effect of students' cognitive capacities, (2) to find out whether school commitment mediated the relation between school motivation and academic achievement,…

The theory of triarchic intelligence posits that, in addition to the widely acknowledged analytical reasoning abilities, creative and practical abilities should be included in the assessments of intellectual capacities and identification of gifted students. To find support for such an approach, the present study examined the psychometric…

The Student-Teacher Relationship Scale (STRS) is widely used to examine teachers' relationships with young students in terms of closeness, conflict, and dependency. This study aimed to verify the dimensional structure of the STRS with confirmatory factor analysis, test its measurement invariance across child gender and age, improve its measurement…

In recent years, there has been a growing interest in therapies that include the learning of mindfulness skills. The 39-item Five Facet Mindfulness Questionnaire (FFMQ) has been developed as a reliable and valid comprehensive instrument for assessing different aspects of mindfulness in community and student samples. In this study, the psychometric…

The authors explored the utility of the Difficulties in Emotion Regulation Scale (DERS) in assessing adolescents' emotion regulation. Adolescents (11-17 years; N = 870) completed the DERS and measures of externalizing and internalizing problems. Confirmatory factor analysis suggested a similar factor structure in the adolescent sample of the…

This study explored the validity of the Utrecht Work Engagement Scale in a sample of 853 practicing teachers from Australia, Canada, China (Hong Kong), Indonesia, and Oman. The authors used multigroup confirmatory factor analysis to test the factor structure and measurement invariance across settings, after which they examined the relationships…
