Do adolescents remember imaginary companions (ICs) from early childhood? Researchers interviewed 46 adolescent participants in a prospective longitudinal study about their ICs from early childhood (age 5 1/2). The existence of one or more ICs was documented in early childhood for 48% of children (G. Trionfi & E. Reese, 2009). At age 16, most…

This study developed an Adolescents' Uncertainty Scale (AUS), with the aim of understanding individual differences in uncertainty among adolescents. In the pretest phase, 507 ninth-grade students were recruited. After exploratory factor analyses, a 25-item AUS with four dimensions--irresoluteness, instability, lack of self-knowledge, and…

Adaptability (adjustment to new and uncertain situations) and grit (perseverance and passion for long-term goals) both sustain students, but their joint contribution has never been explored, and recent studies propose they could compose a single factor. In this study we aim to test whether (1) they actually belong to a single overarching factor as…

Background: Assessment of work performance (AWP) is a test for assessing work performance and can be utilised in matching person-work and applying effective interventions. It was aimed to adjust and to evaluate the validity and reliability of AWP in Turkish with individuals with mild intellectual disability (ID). Methods: The study was conducted…

The Cross-Classified Mixed Effects Model (CCMEM) has been demonstrated to be a flexible framework for evaluating reliability by measurement specialists. Reliability can be estimated based on the variance components of the test scores. Built upon their accomplishment, this study extends the CCMEM to be used for evaluating validity evidence.…

The diversity in classrooms has increased worldwide. An equitable learning experience is the desired outcome. When planning instruction teachers must attend to the varied needs of their diverse students. The study presents a survey that assesses preservice teachers' use of different modalities of multiliteracies, new literacies, and literacy…

Rubric-based observations of pre- and inservice teachers are common practice in schools. Popular observation tools often result in minimal variation in ratings between teachers, require extensive training and time demands for raters, and provide minimal feedback for professional development. Alternatively, direct observation methods are evidenced…

This study aims to develop a scale to determine the Teachers' Management of Undesirable Student Behaviours. The study to determine the construct validity and internal consistency was carried out in the general screening model. The study groups consist of 822 students (458 for AFA; 364 for DFA) studying at various high schools in the centre and…

From the perspective of positive psychology, the study and measurement of subjective well-being has popularized a growing interest towards variables such as affective perception. In an attempt to explain and evaluate the affective structure in positive terms (PA) and negative terms (NA), PANASN affect scale (Sandín, 2003) constitutes the version…

Following COVID-19, the global educational landscape shifted dramatically. Almost every educational institute in Bangladesh undertook a strategic move to begin offering online or blended learning courses to mitigate the challenges created by the pandemic. The TVET sector, particularly the polytechnic institute of Bangladesh, endeavored to explore…

The Kaufman Domains of Creativity Scale (K-DOCS) is a self-reported rating scale that measures creative behaviors in five areas. Despite the vast amount of research on the scale, the internal consistency reliability of K-DOCS scores have not been examined. Specifically, there is no study on the overall reliability coefficients, the variation in…

Research has attempted to explain perceived cues to deception based upon self-report of what participants believe are 'good' cues to deception, or self-report of what cues participants say they base their veracity judgements on. However, it is not clear to what extent participants can accurately self-report what influences their decision-making.…

We present the R package and web app "statcheck" to automatically detect statistical reporting inconsistencies in primary studies and meta-analyses. Previous research has shown a high prevalence of reported p-values that are inconsistent--meaning a re-calculated p-value, based on the reported test statistic and degrees of freedom, does…

In this article, we explore how people revise their belief in a hypothesis and the reliability of sources in circumstances where those sources are either independent or are partially dependent because of their shared, common background. Specifically, we examine people's revision of perceived source reliability by comparison with a formal model of…

Accurate and consistent reviews of documents describing research studies are essential to valid and generalizable inferences in a meta-analysis. Traditionally a small number of reviewers screen studies using the title, abstract, and possibly the full text to determine a study's eligibility for a meta-analysis. This study explores whether reviewing…
