Test anxiety in primary school children: A 20-year systematic review and meta-analysis.

This study sought to systematically review the full body of research on test anxiety in primary (elementary) school children aged 5-12 years. A comprehensive electronic and manual literature search identified 76 studies (85 independent samples; N = 53,617 children) that satisfied inclusion criteria. Inverse-variance weighted random effects meta-analysis showed that test anxiety related negatively to academic achievement in Mathematics (r = 0.

This research synthesis explored whether major personality dimensions relate to body dissatisfaction. A comprehensive literature search identified 26 studies (37 independent samples) that met inclusion criteria (364 effect sizes; n = 39,109). Data were analyzed using inverse-variance weighted random effects meta-analysis.

Self-regulation in childhood as a predictor of future outcomes: A meta-analytic review.

This meta-analysis explores whether self-regulation in childhood relates to concurrent and subsequent levels of achievement, interpersonal behaviors, mental health, and healthy living. A comprehensive literature search identified 150 studies that met inclusion criteria (745 effect sizes; total n = 215,212). Data were analyzed using inverse-variance weighted random effects meta-analysis.

Systematic Review and Meta-Analysis of Self-Serving Attribution Biases in the Competitive Context of Organized Sport.

This meta-analysis explored the magnitude of self-serving attribution biases for real-world athletic outcomes. A comprehensive literature search identified 69 studies (160 effect sizes; 10,515 athletes) that were eligible for inclusion. Inverse-variance weighted random-effects meta-analysis showed that sport performers have a tendency to attribute personal success to internal factors and personal failure to external factors ( = 40, standardized mean difference [SMD] = 0.

A 10-year prospective study of personality and reproductive success: Testing the mediating role of healthy living.

Objective: There is some evidence that personality relates to childbearing in adulthood but the importance of personality for reproductive capacity is unknown. This study explored cross-time associations between the major dimensions of trait personality and self-reported fertility and fecundity.
