This meta-analysis (114 studies, k = 157, N = 21,616) examined the rel
ationship 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 co
rrelations. To account for this variation, the authors conducted a 2-l
evel theory-driven moderator analysis by partitioning the k sample of
correlations first according to the level of task complexity (low, med
ium, and high), and then into 2 classes according to the type of study
setting (simulated-lab vs. actual-field). New directions for future t
heory development and research are suggested, and practical implicatio
ns of the findings are discussed.
