Self-efficacy and work-related performance: A meta-analysis

This meta-analysis (114 studies, k = 157, N = 21,616) examined the relationship between self-efficacy and work-related performance. Results of the primary meta-analysis indicated a significant weighted average correlation between self-efficacy and work-related performance, G(r(+)) = .38, and a significant within-group heterogeneity of individual correlations. To account for this variation, the authors conducted a 2-level theory-driven moderator analysis by partitioning the k sample of correlations first according to the level of task complexity (low, medium, and high), and then into 2 classes according to the type of study setting (simulated-lab vs. actual-field). New directions for future theory development and research are suggested, and practical implications of the findings are discussed.
