The purpose of this study was to investigate the relationship between ICF coaching and early career principals' self-efficacy related to their a) management skills and b) instructional leadership. The sample for this study were principals in a larger urban school district in the northeast who began their principalship between July 2017 and June…

Purpose: This study examined whether there was a significant negative relationship present between engaging in physical activity and the variables of anxiety sensitivity and self-esteem. In addition, it was determined whether aerobic exercise, anaerobic exercise, or stretching exercises were most strongly correlated with anxiety sensitivity and…

Intuitive Eating (IE) theory posits eating in response to internal hunger, and satiety cues minimize impulses to over-consume foods. To assess this relationship, 758 university students (55% male) completed the Intuitive Eating Scale 2 (IES-2) and the Diet History Questionnaire II (DHQ). The IES-2 includes a total score and four subscale scores;…

In causal mediation studies that decompose an average treatment effect into indirect and direct effects, examples of post-treatment confounding are abundant. In the presence of treatment-by-mediator interactions, past research has generally considered it infeasible to adjust for a post-treatment confounder of the mediator-outcome relationship due…

Beginning with debates about the effects of smoking on lung cancer, sensitivity analyses characterizing the hypothetical unobserved conditions that can alter statistical inferences have had profound impacts on public policy. One of the most ascendant techniques for sensitivity analysis is Oster's (2019) coefficient of proportionality, which…

The long-term effects on academic self-concept of grade retention are unclear. The objective is to examine the progression of academic self-concept in relation to school performance for retained students and non-retained students. The academic self-concept of 5712 students (1381 retained students) was evaluated at the fourth and eighth grade of…

This study aimed to describe: the correlation of achievement motivation with student talent, the correlation of self-efficacy with student talent, the correlation of achievement motivation and self-efficacy with students' talents. This study used a quantitative approach with a descriptive method of correlation. While the population of this study…

In evidence synthesis, dealing with zero-events studies is an important and complicated task that has generated broad discussion. Numerous methods provide valid solutions to synthesizing data from studies with zero-events, either based on a frequentist or a Bayesian framework. Among frequentist frameworks, the one-stage methods have their unique…

This retrospective study, undertaken in Norway, examines how reading skills level in 851 fifth graders are related to how the children used their language skills in play and everyday activities as toddlers. Data were collected with the Norwegian National Reading Test and through structured observations by staff in Early Childhood Education…

The focus of this paper is on the empirical relationship between item difficulty and item discrimination. Two studies--an empirical investigation and a simulation study--were conducted to examine the association between item difficulty and item discrimination under classical test theory and item response theory (IRT), and the effects of the…

The heart rate variability threshold (HRVT) is a useful and inexpensive alternative to estimate the ventilatory threshold (VT). However, its validity in women remains underexplored. We investigated the agreement between HRVT and VT in young women and the influence of cardiac parasympathetic status and cardiorespiratory fitness (CRF). Sixty-one…

Given the recent push for universal screening, it is important to take into account how well a screener identifies children at risk for reading problems as well as how screener and sample information contribute to this classification. Picking the best cut-point for a particular sample and screening goal can be challenging given that test manuals…

School violence is a growing issue that adversely affects learning, academic achievement, and student growth. Drawing upon the heuristic model of school violence proposed by the study proposes to examine the direct and indirect relationship (through teacher satisfaction) between paternalistic leadership (PL) and school violence in the Arab…

This study examined the link between two teaching characteristics (i.e., teacher support and cognitive activation) and achievement emotions in Chinese mathematics classrooms. The data were collected from 2232 students (49.9% male; M[subscript age] = 13.85, SD = 0.81) in 84 mathematics classrooms across 12 secondary schools in Jiangsu, China. The…
