The purpose of the study was to develop the Teachers' Mental Toughness Questionnaire (TMTQ). The questionnaire was developed in six stages: item generation, content validity, exploratory factor analysis, reliability tests, convergent validity tests, and discriminant validity. The factor analysis indicates that it measures six factors: team,…

This study describes the development of the science, technology, engineering, and mathematics (STEM) Scale, intended to assess parental attitudes toward school programs designed to deliver STEM, and evaluates its psychometric properties. The study group included 400 parents of students (138 males and 262 females) enrolled in STEM programs…

Stress is a complex construct that is related to resilience and general health starting in childhood. Despite its importance for student health and well-being, there are few measures of stress designed for school-based applications. In this study, we developed and initially validated a Stress Indicators Scale using five samples of teachers,…

Conceptualizing and testing factors that contribute to the success of community-academic partnerships are critical to understanding their contributions to the health and well-being of communities. Most measures to date focus on factors that contribute to the development of new partnerships, and only a few have been adequately tested and validated.…

Short-form development is an important topic in psychometric research, which requires researchers to face methodological choices at different steps. The statistical techniques traditionally used for shortening tests, which belong to the so-called exploratory model, make assumptions not always verified in psychological data. This article proposes a…

Computational thinking (CT) is regarded as a valuable skill set for the students of the 21st century, fostering problem-solving skills applicable to academic disciplines and everyday problems. Assessing CT involves evaluating the development of its concepts, practices, and perspectives. However, establishing comprehensive and validated assessments…

This article presents the process of constructing and validating a test of metalinguistic awareness (MLA) for young school children (age 8-10). The test was developed between 2021 and 2023 as part of the MetaLearn research project, financed by The Research Council of Norway. The research team defines MLA as using metalinguistic knowledge at a…

Computer adaptive testing (CAT) is an increasingly common mode of test administration offering improved test security, better measurement precision, and the potential for shorter testing experiences. This article presents a new item selection algorithm based on a generalized objective function to support multiple types of testing conditions and…

Background: In secure residential facilities, group climate perceptions of clients with mild intellectual disability or borderline intellectual functioning are systematically assessed for quality improvement. A valid and reliable measure may ensure that this process is consistent. The Group Climate Inventory--Revised (GCI-R) is a new measure to…

In the current research, we developed and tested a Cyber Malevolent Creativity Behavior Scale (CMCBS), which contains 11 items in three dimensions and aims to measure the degree of individuals' cyber malevolent creativity through malevolent creative behaviors in their lives. The results revealed satisfactory reliability with Cronbach's [alpha]…

Museums and science centers are constantly changing scientific environments which exert a lasting positive impact on the society through the popularization of science. One of the most effective strategies employed by these science popularization venues is the organization of scientific exhibitions using scientific devices which are presented to…

Research at the secondary school level provides compelling evidence to suggest that a positive school climate is related to improved health, wellbeing, and cognitive outcomes for students. In response to these findings, school systems around the world are mandating the collection of school climate data in schools. However, reviews of the…

The Standards for Mathematical Practice (SMPs; CCSSI, 2010) describe mathematical behaviors and habits that students should express during mathematics instruction. Teacher candidates should have knowledge about the SMPs and their implications for mathematical instruction. This study aims to share the validity evidence for interpretations of…

Purpose: The present study develops, conceptualizes and validates a scale based on the transactional stress theory to assess the perceived challenge and hindrance demands of doctoral programs that impact doctoral students' psychological well-being. Design/methodology/approach: This research employs an exploratory-mixed methodology comprising five…

This article reports on the development and psychometric evaluation of a new teacher observation instrument to systematically assess young primary school students' well-being and detect potential indicators of psychological trauma, the RaPTOSS: "Risk and Protective factors Trauma Observation School Situations." The RaPTOSS is developed…
