The study group of the research consists of 300 students studying in 3 different secondary schools in Turkey in the first semester of the 2022-2023 academic year. A 32-item…

Information literacy is a fundamental component in the academic development of future professionals. The aim of the study was to evaluate the metric properties of the 'questionnaire of self-perceived information competences', analyzing the factorial structure, internal consistency, convergent validity, factorial invariance according to gender and…

Purpose: Wellbeing refers to a person's overall happiness and satisfaction with life. Wellbeing for people with Intellectual and Developmental Disabilities (I/DD) and their families is historically significantly lower compared to the general population. It is important in the context of behavioral health treatment to not only measure the…

As part of a validation study of the Exercise Planning and Scheduling (EPS), and Goal-Setting (EGS) Scales, which were translated from English to Brazilian Portuguese, we aim to: present evidence of reliability and validity for the translated scale; and, explore the effects of non-labeled response categories of rating scales. The sample comprised…

Gas Turbine Engines (GTE) have the highest power-to-weight ratio among Internal Combustion Engines (ICE). Its modularity and ability to utilize various types of fuel make it highly recommended in power plants, naval transportation, and, of course, the most equipped in aviation. The lack of GTEs' real data is increasing a recognized need for…

Language assessment is a central aspect not only of language education in the general population, but also amongst heterogeneous, low-incidence populations. One such population are immigrant deaf and hard-of-hearing learners (IDML) who are bimodal-multilingual and whose languages development often includes the spoken, written, and/or signed…

In recent years, there has been a proliferation of instruments for assessing mental health (MH) among autistic people. This study aimed to review the psychometric properties of broadband instruments used to assess MH problems among autistic people. In accordance with the PRISMA guidelines (PROSPERO: CRD42022316571) we searched the APA PsycINFO via…

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…

The current study focused on establishing the factor structure, reliability, discriminant validity, and construct validity of the Youth Programs -- Community Education Environment Scale (YP-CEES) using a large diverse sample of 1,969 youth participating in relationship education programs in multi-session workshops facilitated by trained…

Background: Difficulties identifying anxiety disorders in primary-school aged children present significant barriers to timely access to support and intervention. This study aimed to develop a brief assessment tool that can identify children with anxiety disorders in community settings, with a high level of sensitivity and specificity. Methods:…

Sound waves are one of the important topics studied in physics. However, students' graph representation is still low, leading to their low concept understanding of physics learning. Therefore, it is necessary to optimize the learning process to improve students' graph representation by providing a valid and reliable graph representation test…

This study assesses the psychometric properties of the Sense of Community Scale in School (SOC-S), among 1027 seventh-grade primary school students (M = 12.5; SD = 0.69) in urban schools in Chile. The results affirm the multidimensional conceptualization of the sense of community, aligning with the theory proposed by McMillan and Chavis (1986),…

The quadripartite violence typology categorizes aggression into rage, revenge, reward, and recreational aggression. Furthermore, the general aggression model highlights the interaction between personal and contextual factors in shaping aggressive behavior. Whereas the four types of aggression are considered as personal factors, a contextual…

Schools carry the important task of fostering democratic values like equality and tolerance among students. This study examined to what extent a valid and reliable measurement instrument can be developed to gain insight into students' attitudes towards democratic values and what can be concluded based on this measurement. We constructed the…
