To draw informed conclusions from research studies, research consumers need full and accurate descriptions of study methods and procedures. Preregistration has been proposed as a means to clarify reporting of research methods and procedures, with the goal of reducing bias in research. However, preregistration has been applied primarily to research…

The current study aimed to adopt and assess the psychometric properties and measurement invariance of Grit-S among Omani and American students (N = 487) using Exploratory Factor Analysis (EFA) and Multi-Group Confirmatory Factor Analysis (CFA). The scale's construct validity was estimated by investigating its associations with achievement goal…

Obsessive-compulsive disorder (OCD) in adolescents is understudied in Italy. This study evaluated the Italian Obsessive Compulsive Inventory--Child Version (OCI-CV) and its predictive validity on OCD symptoms at 1-year-follow-up, an aspect that was not investigated by previous international research. Use of OCI-CV in schools might enhance early…

Self-regulatory abilities have been shown to be closely linked to academic success. There are a variety of measurement tools to assess self-regulated learning in pupils and students. Crucially, preschool age marks a sensible period for the maturation of self-regulated learning (SRL) and related abilities such as executive-control functions (EF).…

Recent advances in policy development and professional practice in the field of early learning and child care have led to the expectation that it is appropriate and advantageous to include children with disabilities and extra support needs in early child care and learning programs. Yet, to date, evidence-based research on the effects of…

Learning problems (LP) can have wider implications than the academic deficits per se. The goal of the present series of studies was to develop a reliable and valid quality-of-life measure targeted to children and adolescents with LP. In Study 1, using a 35-item questionnaire, we surveyed 151 parents/guardians of children referred for assessment of…

Purpose: This research aimed to determine school happiness level of the teachers based on their opinions. For this purpose, 'School Happiness Scale' was developed by the researchers. The validity and reliability of the School Happiness Scale were tested. And then, the scale was applied to 484 teachers to determine their school happiness level.…

Despite the concerns regarding value-added models (VAMs), advocates hold strong to VAMs' theoretical strengths and potentials, while adopting a set of agreed-upon albeit "heroic" set of assumptions, without research in support. These assumptions transcend promotional, policy, media, and research-based pieces, but they have never been…

The purpose of this study was to validate a new inventory designed to measure epistemic beliefs concerning the justification of knowledge claims encountered on the Internet. Confirmatory factor analysis of the scores of 394 preservice teachers showed that a three-factor model including justification by authority, justification by multiple sources,…

Increasing rates of autism spectrum disorder (ASD) and younger age at diagnosis pose a challenge to preschool intervention systems. In Sweden, most young autistic children receive intervention service in community-based preschool programs, but no tool is yet available to assess the quality of the preschool learning environment. This study adapted…

This research pioneered the investigation of the role of doctoral students' thinking styles in their program satisfaction and perceived intellectual competence. Participants were 285 STEM (science, technology, engineering, mathematics) students in Hong Kong. Results showed that students' thinking styles as measured by the Thinking Styles…

Integrated STEM education holds the promise for students' meaningful science instruction. However, the implementation of integrated STEM-based approaches for science learning might be difficult for teachers due to the lack of expertise and instructional materials. Therefore, this study focused on the preparation and validation of an integrated…

In the contemporary world, career counseling professionals need to focus on skills that help people bring benefit from positive chances and minimize the damage of negative events. The Planned Happenstance Career Inventory (PHCI) was created to measure these skills. The main aim of the present study was to test the dimensionality and concurrent…

Researchers in higher education frequently evaluate institutional effectiveness as the difference between an actual and predicted graduation rate, but little is known about whether such a method is reliable or valid. This study examines the measurement properties of effectiveness scores derived from regression residuals for community colleges in…

Aim: To evaluate the psychometric properties of a new measure of school belonging. Rationale: The sense of belonging to the school (organisation) as opposed to individuals within a school (peers) plays a significant part in pupils' behaviour and wellbeing. To date, few psychometrically robust, theoretically driven and brief scales exist.…
