A sample suffers range restriction (RR) when its variance is reduced comparing with its population variance and, in turn, it fails representing such population. If the RR occurs over the latent factor, not directly over the observed variable, the researcher deals with an indirect RR, common when using convenience samples. This work explores how…

The present study sought to assess the psychometric properties of the Iranian adaptation of the Vietnam Teacher Resilience Scale for Asia (VITRS), referred to as the Iranian Teachers' Resilience Scale (ITRS) and to examine its measurement invariance across middle and high school teachers in Iran. In total, 700 participants completed the…

Examinations of the internal structure of the Depression, Anxiety, and Stress Scale-21 (DASS-21) have yielded inconsistent conclusions within and across cultural contexts. This study examined the dimensionality and reliability of the DASS-21 across three theoretically plausible factor structures (i.e., unidimensional, oblique three-factor, and…

Evaluation of child-friendly school (CFS) policies is essential to determine the achievements of school efforts in reducing violence cases. This research aims to proving the reliability and validity of CFS policy evaluation instruments in elementary schools with different locations. This investigation uses the Context Input Process Product (CIPP)…

Purpose: This study explores the psychometric properties of the Persian version of the Child and Youth Resilience Measure--Revised (CYRM-R) in adolescent population. Method: A sample of 323 Iranian adolescents (12-18 years old) completed the CYRM-R, Resilient Scale (RS), Beck Depression Inventory (BDI-II), and Mental Health Continuum Short Form…

In higher education, it is essential that students apply what they have learned to solve problems in their community. Meaningful learning is the main means to increase the accumulation of knowledge and achieve the transfer of learning, which is why the present study aimed to: design and evaluate the psychometric properties of a scale that measures…

The aim of the study is to adapt Preschool Children's Science Motivation Scale (PCSMS) developed by Oppermann et al. into Turkish and conduct the validity and reliability analyses. This scale is considered important in terms of evaluating the science motivation of preschool children through the science concepts they are familiar with, based on…

Our purpose in this study was to further examine the psychometric properties of the Quality of Life for Children with Autism Spectrum Disorder (QOLASD-C) scale. We first investigated the factor structure and the internal consistency of the scale. The bifactor model showed good fit and strong reliability. Second, we used multiple-indicators…

The Flourishing Scale is a new scale designed to measure psychological well-being. FS has been translated into more than 10 languages (e.g., Portuguese, Russian, Turki, Spanish, Egyptian, French, Chinses, Japanese, Malay, Urdu, and Persian). The psychometric analysis of the Flourishing Scale has not been explored in the Malaysian context. The aims…

The purpose of this research is mainly to explore the validity and reliability of PERMA instruments to determine the nature of PERMA for Chinese university EFL students. A total of 309 Chinese university EFL students from 10 universities in Gansu province were investigated. Selected by cluster random sampling, the extracted data from the survey…

In this study, we present a new instrument, the Participation and Engagement Scale (PES), for the evaluation of the students' involvement in STEM-oriented activities. The instrument was administered to about 1000 secondary school students who participated in the activities of the Italian "Piano Nazionale Lauree Scientifiche" in Biology,…

The aim of this study was to assess the reliability and validity of ERQ in a group of Egyptian adolescents. 648 adolescents from middle schools in Nasr city, Egypt were recruited. These adolescents aged 14-15 years old (M=14.4, SD=2.22). Of which,400 were females (61.72%) while 248 were males (38.27%). Exploratory Factor Analysis, with CFA and…

Although there is a robust body of research that has addressed the psychometric properties of the Learning and Study Strategies Inventory (LASSI) in different populations, no study has yet investigated the factor structure and congeneric reliability of the Arabic version of the Learning and Study Strategies Inventory, 2nd edition (LASSI-II) among…

The purpose of this study was to examine the psychometric properties of Cognitive Emotion Regulation Questionnaire (Garnefski, Kraaij et al., 2002), using a sample of adolescents from Egypt, aged 13, 14 and 15 years. The results indicate that the nine-factor model was successful, obtaining adequate fit indexes: X[superscript 2], df=381.3,…

Intercultural competence is a crucial element of foreign language education, yet the multifaceted nature of this construct makes it inherently difficult to assess. Although several tools for evaluating intercultural competence currently exist, research on their use in secondary school settings is scarce. This study reports on the development and…
