This study evaluates the Children's Worlds Psychological Well-Being Scale (CW-PSWBS) within a diverse international cohort of children aged 10 and 12, utilising Classical Test Theory (CTT) and Item Response Theory (IRT) methodologies. Through a detailed psychometric analysis, this research assesses the CW-PSWBS's structural integrity, focusing on…

In response to the prevalence of perceived internship Pick-up Artist(PUA) behaviours and the lack of appropriate measurement tools, the purpose of this study was to develop and validate a new self-designed questionnaire, the Perceived Internship PUA Scale (PIPUAS), to assess college student interns' perceptions of internship PUA behaviours. The…

Objective: Many treatment engagement challenges are documented for adolescents with ADHD. Across contexts, helping professionals (i.e., therapists, prescribers, educators, coaches) might benefit from an engagement strategy toolbox to facilitate work with adolescents with ADHD and their families. Method: The current study describes the development…

This study assesses the psychometric properties of the School Support Scale (SSS), part of the CHKS's Resilience Youth Development Module (RYDM; Furlong et al., 2009), among 231 sixth- and seventh-grade students in urban public schools in Chile. Results indicated satisfactory psychometric properties, replicating a unifactorial structure observed…

This study investigated the preliminary psychometric properties of the Pathway to Independence Inventory (P2I), a transition assessment tool designed to meet the needs of transition-age students with disabilities (SWD) with support needs in the areas of adaptive skills, executive functions, and social skills. Analyses examined the item-total…

The introduction of computing education into curricula worldwide requires multi-year assessments to evaluate the long-term impact on learning. However, no single Computational Thinking (CT) assessment spans primary school, and no group of CT assessments provides a means of transitioning between instruments. This study therefore investigated…

The extent to which the Principal Instructional Management Rating Scale (PIMRS) is sensitive and appropriate to be used in different cultural contexts remains underexplored in the literature. To address this research gap, this study attempts to validate a Malay language version of PIMRS by assessing convergent, discriminant, and criterion validity…

Background: There are long-held concerns about how graduate research programs prepare engineering PhD students for professional practice. Suitable instruments are lacking to effectively assess how research experiences contribute to the success of graduate students becoming professionals. Purpose: The purpose of this work is to examine evidence of…

The current study sought to evaluate the SASTSc in two samples of students taking a statistics course that incorporates statistical software. The SASTSc was given at two time points, once at the beginning of the semester and then again at the end of the semester. Our evaluation included examining competing factor analytic models, examining…

Research Findings: In recent years, several initiatives have been put into place both federally and state-wide to expand access to high-quality early education programs. At the center of these efforts are the tools that measure program or classroom quality. The present study compares the psychometrics of two such tools used in Michigan, the…

IQ tests provide numerous scores, but valid interpretation of those scores is dependent on how precisely each score reflects its intended construct and whether it provides unique information independent of other constructs. Thus, IQ scores must be evaluated for their reliability and dimensionality to determine their psychometric utility. As a…

The main purpose of this study was to design and validate a scale to assess the teamwork competency of undergraduate students (TCS, Teamwork Competency Scale). The research instrument designed and subjected to validation has nine specific dimensions: Collective effectiveness, learning orientation, group goal setting, planning and coordination,…

The present study examined the metric properties of the Delaware School Climate Survey -- Student (DSCS-S) using a sample of 1524 Serbian high school students. Of the total number of participants, 764 were male and 760 were female with age ranging from 16 to 20 years (M = 17.67, SD = 0.65). Confirmatory factor analysis (CFA) demonstrated that a…

The Scale of Physical and Verbal Aggressiveness has been an instrument widely used in the scientific literature to measure physical and verbal aggressiveness, both in children and adolescents as well as in parents. The original scale has shown adequate psychometric properties. However, the scale has not been previously validated in Spanish, and no…

This study presents the development of a mathematical creativity test and exploration of its psychometric properties. The study was conducted in six public schools and a high ability center between 2015 and 2018. The sample of the study included 1129 middle school students. The Mathematical Creativity Test (MCT) consists of problem posing, making…
