This study examined the psychometric properties of the Positive and Negative Affect Schedule for Children-Short Form (PANAS-C-SF) in a diverse sample of 15-year-olds in the United States [N = 4382]. Multiple measurement models, including a one-factor model, two-factor orthogonal and oblique models, a three-factor model (PA, Fear, and Distress),…

The present study aimed to adapt the Teacher Self-Efficacy Scale (TSES) developed by Schwarzer et al. (1999) into Italian and to test its validity and reliability. In a group of teachers (N = 683; 83% female), the factor structure (Confirmatory Factor Analyses), construct validity (latent relations with burnout variables), measurement invariance…

This study aimed to translate the Japanese version of the Life Skills Scale for Adolescents and Adults (LSSAA) into Chinese, English, and Korean, simplify it, and assess its reliability and validity. Validation was performed using individual data of 9941 high-school students from China, Japan, Korea, and the United States collected by the 2021…

The present article describes the development and validation of the Informational and Normative Conformity Scale (SKI-N), a brief self-report tool capturing adolescents' general propensity to adopt a conformist attitude, and the underlying motives for doing so. The presentation includes a description of scale construction and an assessment of the…

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…

This article is the first attempt to validate the Entrepreneurial Intention Questionnaire (EIQ) in secondary education students. It is based on the Theory of Planned Behavior (TPB) and includes its constructs: attitude towards entrepreneurship, subjective norm, entrepreneurial self-efficacy, and entrepreneurial intention. The promotion of…

We present the development and validation of the Digital Addiction Scale for Teenagers (DAST), describing the pilot study (N = 40 students) and main study (N = 4493) with Estonian students aged 11-19, in spring 2020. Our aim was to create a scale suitable for psychoeducational assessment of teenagers' behaviour and feelings towards digital…

Previous work has focused on positive feelings of mattering, which pertain to the human need to feel significant. In the current article, we examine a complementary yet distinct construct involving feelings of not mattering that may arise from being marginalized and experiences that heighten a sense of being insignificant to others. We also…

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…

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 current research investigated the psychometric characteristics of the Turkish adaptation of the Teacher Emotions Scale (TES). Study I included a sample of 164 Turkish middle school teachers, and Study II included a sample of 222 mathematics teachers. The three-emotion factor model was confirmed in both studies with satisfactory reliability…

The present work describes the development of a new measure of school counselors' perceived self-efficacy regarding their knowledge of information and processes necessary to effectively guide their students through the college transition process. Researchers developed the School Counselor Efficacy for College Knowledge Questionnaire and examined…

This article develops and validates the Positive and Negative Adolescent Life Experiences (PANALE) scale, a 11-item tool that enables researchers to measure adolescent stressors in a more valid and efficient manner than existing adolescent stressors scales. The PANALE presents good psychometric qualities, in terms of construct validity (factorial…

The Academic Intrinsic Motivation Scale (AIMS) measures key components of student intrinsic motivation (IM). We investigate score validity and reliability of a downward extension of the AIMS developed for students in the high school context using a sample of students from the Pacific Northwest region of the United States. Through classical test…
