Mediation models have been widely used in many disciplines to better understand the underlying processes between independent and dependent variables. Despite their popularity and importance, the appropriate sample sizes for estimating those models are not well known. Although several approaches (such as Monte Carlo methods) exist, applied…

Structural equation modeling (SEM) and path analysis using composite-scores are distinct classes of methods for modeling the relationship of theoretical constructs. The two classes of methods are integrated in the partial-least-squares approach to structural equation modeling (PLS-SEM), which systematically generates weighted composites and uses…

Path models with observed composites based on multiple items (e.g., mean or sum score of the items) are commonly used to test interaction effects. Under this practice, researchers generally assume that the observed composites are measured without errors. In this study, we reviewed and evaluated two alternative methods within the structural…

The major purpose of this study was to create a path analysis model of academic success in a group of university students, which included the variables of academic confidence and psychological capital with a mediator variable--academic coping. 400 undergraduates from Marmara University and Istanbul Commerce University who were in sophomore, junior…

Teachers are expected to update their instructional strategies. Teaching learning approaches and epistemological beliefs may affect teaching practices. The aim of this study is analyzing the relation of variables that effect epistemological beliefs and teaching learning approaches of teacher candidates on a statistical model. According to…

In this two-wave longitudinal study, concurrent and longitudinal relations among teacher-reported shyness, peer acceptance, and academic achievement were examined (Ns = 162 and 155; and Ms[subscript age] = 6.09 and 7.07 years). Concurrently, at both times, shyness was negatively related to peer acceptance and academic achievement, and peer…

Little empirical evidence is available on what drives young people to engage in higher education. Such knowledge is crucial in order to motivate students to make the most of their potential. This study surveyed a total of 294 Swedish high school students. The result shows that intentions play a mediating role between students' attitudes and the…

A good analysis of the success factors in the university entrance exam, which is an important step for academic careers of students, is believed to help them manage this process. Properties such as self-regulation and learning approaches adopted by students undoubtedly influence their academic achievement as well as their success in university…

During adolescence, it can be very stressful for young men and women to accept their bodies. However, it is important during this stage of their development to accept their body as it is. If they cannot complete this task successfully, young people may experience stress and anxiety. This study aims to investigate the mediating effects of body…

Teachers' professional development (PD) receives a great deal of attention in current educational settings. However, research has shown that many teachers hesitate to attend PD programs. In this study, data were collected from 270 elementary school teachers and were subjected to confirmatory factor analysis and structural equation modeling to…

The objective of the present study is to examine the correlation between the five factor personality traits of pre-service teachers and their attitudes towards the teaching profession and to test the mediating role of the pre-service teachers' self-efficacy beliefs. The study population included pre-service teachers that attended the…

The extent to which a student experiences situational interest during a learning task is dependent on at least two factors: (1) external stimuli in the learning environment that arouse interest and (2) internal dispositions, such as individual interest. The objective of the present study was to disentangle how both factors influence situational…

The aim of the present study was to test whether teacher-student relationship (TSR) quality and student-student relationship (SSR) quality at class level and class moral disengagement (CMD), considered together in a single model, were related to class prevalence of victims (CPV) of bullying. A sample of 899 Swedish children was recruited from 43…

One of the central assumptions of the causal-indicator literature is that all causal indicators must be included in the research model and that the exclusion of one or more relevant causal indicators would have severe negative consequences by altering the meaning of the latent variable. In this research we show that the omission of a relevant…

Objective: The objective of this study was to evaluate the determinants of sugary drink consumption among overweight and obese adults attempting to lose weight using the Integrative Model of Behavioural Prediction (IMB). Design: Cross-sectional design. Method: Determinants of behavioural intentions (attitudes, perceived norms and perceived…
