This study investigates how sensitively the current grit measure (Grit-S) is able to reflect the differences between individuals (i.e. item discrimination) and change within individuals (i.e. sensitivity to change of items) using longitudinal data. Data from the Korean Children and Youth Panel Study 2018 of elementary (fourth grade) and middle…

The study aimed to test the psychometric properties of a Portuguese adaptation of the "Adolescent Students' Basic Psychological Needs at School Scale" (ASBPNSS). For this, we used data from a sample of eighth graders (N = 1648; M[[subscript age] = 14.1 years; 46.9% girls) from Portugal. Cronbach alpha and omega coefficients showed the…

Using expert reviews and item response theory (IRT), this study evaluated the language- and culture-related construct-irrelevant variance and reliability of the 2019 TIMSS sense of school belonging scale (SSBS) for grades 4 and 8. The five items of the SSBS, which were identical for both grades, were reviewed for the language- and culture-related…

The factor structure of the measure of school engagement 'Engagement Versus Disaffection with Learning: Teacher Report' was investigated in the sample of 360 Swedish 6th graders. Confirmatory factor analyses showed no support for the suggested four-factor structure including behavioural engagement, emotional engagement, behavioural disaffection…

For decades, achievement goal theory has been extensively used, but empirical research still requires a clearer understanding of the underlying factors conceptualized and measured during secondary school periods. In light of the increasing use of longitudinal studies in motivation research, this study aims to investigate the longitudinal…

Today, emoji have become a popular option for anchoring the categories of Likert-type scales applied to not only adults but also children. The aim of this study was to investigate the effects of category labeling with emoji by comparing the psychometric properties of the emoji- and verbal-anchored versions of the mathematics motivation scale…

Based on the dichotomous classroom goal structure model and TARGET framework, this study developed and validated a new Dichotomous Classroom Goal Structure Questionnaire (DCGSQ). A total of 339 seventh-grade students in Beijing completed the two-phase survey in Study 1. Exploratory factor analysis and reliability analysis were used to assess the…

The relationship between latent trait and test-taking speed is an important area of study in assessment research. In addition to contributions of such studies to psychometrics, the factors that affect both ability and speed have implications for test development and have policy consequences especially if the tests are high stakes. This study…

In this article, we present a multidimensional school climate questionnaire, based on an adaptation and validation of the Socio-Educational Environment Questionnaire, which is an instrument developed in Canada, assessing several dimensions of school climate. In particular, the aim of this research was to create a Multidimensional School Climate…

Character strengths are an important foundation for positive development and thriving in adolescence. Most research on character strengths has been conducted with youths in Western cultures. We examined character strengths in relation to positive and negative well-being indicators in a sample of Iranian youths. We investigated the reliability and…

We tested the reliability and construct validity of a Chinese translation of one of the forms of the Behavior Assessment System for Children (3rd Edition)--Self-Report of Personality for adolescent 11- to 21-year olds (BASC-3-SRP-A). The BASC-3-SRP-A yields 16 subscales that form four composite scales. Data were obtained from 444 12- to 14-year…

Student engagement is typically regarded as being a multidimensional construct, but there remains no clear consensus about its precise conceptualization. Several current measures of student engagement are limited by their omission of relevant dimensions and/or poor correspondence between dimension labels and item content. To address these…

The objective of the present study was to develop and assess the validity of a short form of the Child-Adolescent Perfectionism Scale (CAPS). Two Portuguese samples composed of 756 adolescents were used to cross-validate the factorial structure of a nine-item Child-Adolescent Perfectionism Scale--Short Form (CAPS-SF). The CAPS-SF consists of a…

We used multilevel factor analyses to investigate the structure of the Teacher as Social Context Questionnaire (TASCQ)-short form--a prominent measure of teacher practices that promote student motivation to learn. Based on Self-Determination Theory (SDT), the TASCQ contains three scales: Autonomy Support, Structure, and Involvement. Few studies…

Little research has, to date, explored students' coping in the academic domain. Yet, children and adolescents frequently refer daily academic difficulties as a common source of stress. The ways children respond to academic demands have the potential to make a difference in their learning and achievement. Therefore, the availability of a measure of…
