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)…

This research aims to develop an instrument for the evaluation of impulsivity traits in children and to examine the psychometric features of the developed scale. The process of developing the scale involved three main phases: namely, item generation, evaluation of content validity, and analysis of psychometric properties. The study sample…

The aim of this study was to develop and validate a psychometrically-sound instrument to assess students' perceptions about class cohesion. Two studies were conducted. In Study 1, four steps were established: (1) development of the Class Cohesion Questionnaire (CCQ); (2) item selection; (3) item compression; and (4) exploration of psychometric…

This paper reports an investigation into the psychometric properties of the COR-Advantage1.5 (COR-Adv1.5) assessment tool, a criterion-referenced observation-based instrument designed to assess the developmental abilities of children from birth through kindergarten. Using data from 8534 children participating in a state-funded preschool program…

Locus of Control (LOC) is a general term used in social and educational psychology to refer to the perceived source of control for behavioural outcomes. Since the 1980s, various instruments have been developed to measure this construct in relation to pro-environmental behaviours and action. In this article, we revisit the value of this construct…

Background: Although the Depression Anxiety Stress Scales, Short Form (DASS-21) was developed for adults, its authors noted no compelling reasons to not use the measure with youth as young as 12 years. Despite increasingly widespread use with youth, psychometric evidence in support of its use with this population needs to be investigated to fully…

Although equality of opportunity in education is a current and important issue, most of the studies on this subject are based on theoretical studies rather than empirical studies. The main reason for this can be said to be the lack of a valid and reliable measurement tool in this field. For this reason, this study aims to develop a valid and…

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)…

Bullying is a form of school violence that has recently received the attention of school psychologists. One of these problems that exists in almost all schools is the phenomenon of school bullying. The aim of this study is to examine the psychometric reliability and validity of the Participant Role Scale in bullying in Persian and compare the…

This article details a two-phase study of the development and validation of a mentor attunement scale (MAS). Phase 1 involved theory-driven generation of 20 items to measure four facets of attunement. Rasch analysis of data collected from 390 youth mentors indicated problematic reverse-coded items, which were eliminated to improve scale…

The Kaufman Domains of Creativity Scale (K-DOCS; Kaufman, J. C. (2012). Counting the muses: Development of the Kaufman domains of creativity scale (K-DOCS). Psychology of Aesthetics, Creativity, and the Arts, 6(4), 298-308. doi:10.1037/a0029751) is a self-report assessment of five creative domains: Everyday, Scholarly, Performance, Scientific, and…

This empirical investigation examined the cross-cultural usefulness of a measure of creative potential, namely the short form of the Runco Ideational Behavior Scale (RIBS). The RIBS has been used in several investigations and existing data show it to be a reliable criterion measure, usually with a two-factor structure. Scores from the RIBS…

The aim of this study is to adapt the Statistics Anxiety Scale (SAS) developed by Vigil-Colet et al. (2008) to Turkish. This study is expected to fill an important gap in the literature since no valid and reliable specific statistics anxiety scale developed or adapted in Turkish for undergraduate students in the literature is available. The sample…

The purpose of this research is to create a reliable and valid scale to assess AIlessphobia in Education (the fear of being without Artificial Intelligence in education) among university students. In three phases, a sample of 1378 undergraduate students from different faculties at a public university participated in the reliability and validity…

Researchers developed and initially validated a client-report measure of counselors' cultural humility, entitled the Cultural Humility and Enactment Scale (CHES). The sample includes 434 adults recruited from web-based surveys. Exploratory factor analyses were performed to examine the initial factor structure of the CHES. Bivariate correlations…
