That is, the degree of knowledge someone has about…

The study examined the psychometric structure of Basic Needs Satisfaction in General Scale (BNSG-S) with a sample of 495 college students. It compared the original 21-item version (Gagné, 2003) with the shortened 16-item version (Johnston & Finney, 2010), both with and without method effects. A series of confirmatory factor analyses (CFA)…

The Neurodevelopmental Ecological Screening Tool (NEST) is a new instrument to screen children for developmental challenges. This article describes the validation of the NEST neurodevelopmental domain. Data were collected from a nationwide purposely restricted sample of caregivers of children aged 3-5 years (n = 231) living in poverty and…

As one of the 21st-century skills, self-directed learning (SDL) has received widespread attention and has become an essential research topic in education. In this study, we examined the psychometric properties of the SDL scale (SDLS) (Lounsbury et al., 2009) with a sample of 408 Chinese undergraduates. Previous research on Chinese students has…

In primary schools, the incorporation of STEAM education has become a widespread trend, as it is believed to have the potential to enhance the quality of education and foster students' competencies. This investigation aimed to explore the definition, measurement model, and scale of students' STEAM competence, emphasizing their hands-on experiences…

Cultural variations in affective experiences are observed. Research on positive affect with refined categorizations has been limited. This study examined the Affect Valuation Theory and its measure, the Affect Valuation Index (AVI), using a sample of high school students from rural China (N = 676, M[subscript age] = 16.17 years, SD = 0.94). The…

A short form of the 60-item computer-based orthographic processing assessment (long-form COPA or COPA-LF) was developed. The COPA-LF consists of five skills, including rapid perception, access, differentiation, correction, and arrangement. Thirty items from the COPA-LF were selected for the short-form COPA (COPA-SF) based on cognitive diagnostic…

Stage fright is a natural and very common phenomenon that affects everyone who must present themselves in public. However, it has a negative impact on the health and voice emission of children and adolescents, which is why it is important to study and measure it. Unfortunately, there are no appropriate tools for examining public presentation…

The present studies report the development of a PROACTIVE coping scale to evaluate actions used by U.S. college students to prevent or prepare for potential future stressors. Results of EFA and CFA using two samples of U.S. college students (total N = 1123) indicated the viability and stability of a 19-item four-factor model of proactive coping:…

Since classroom climate is inherently a group level phenomenon, we argue that measures shown to be valid and reliable in multi-level settings are needed. We propose a brief, 5-item measure of classroom climate and demonstrate its reliability and validity in multi-level structural equation models. The measure demonstrated good reliability and we…

Minority stress theory is a model for understanding health disparities among sexual minorities, defined as those who experience a level of same-sex attraction, identity, or behavior. Methods for assessing minority stress among youth included only adult measures until the development of the Sexual Minority Adolescent Stress Inventory (SMASI). The…
