This meta-analysis examined whether motivation mediated the relationship between self-efficacy, locus of control, and academic achievement. Thirty-seven studies providing correlation estimates for 40 different samples were included in the analysis. The data from these studies were fitted to three models using a two-stage structural equation…

Meta-analytic Structural Equation Modeling (MASEM) is the combination of meta-analysis (MA) and structural equation modeling (SEM). With new MASEM methodologies developed over the past few years, there is an opportunity to compare the past approaches with the new ones. The purpose of this dissertation is two-fold. First, the parameter estimates,…

Openness to experience has often been linked to academic achievement because it subsumes traits such as curiosity, open-mindedness, thoughtfulness, and intellectuality. However, recent meta-analyses have reported rather small true correlation estimates. In this article, we first provide a comprehensive rationale for a relationship between openness…

The present study took a meta-analytic approach to investigate whether students' engagement acts as a mediator in the association between affective teacher-student relationships and students' achievement. Furthermore, we examined whether results differed for primary and secondary school and whether similar results were found in a longitudinal…

Murayama and Elliot (2012) made a significant contribution to the literature on competition by presenting the results of 2 meta-analyses and 3 primary studies on the relation between competition and performance. Murayama and Elliot established that in general, there is no relationship between competition and performance. They then made the case…

What is the relation between competition and performance? The present research addresses this important multidisciplinary question by conducting a meta-analysis of existing empirical work and by proposing a new conceptual model--the opposing processes model of competition and performance. This model was tested by conducting an additional…
