Self-efficacy and task performance: A meta-analysis
Abstract
This meta-analysis (121 studies, k = 148, N = 16441) examined the relationship between self-efficacy expectations and task-performance. Results of the primary meta-analysis revealed a significant weighted average correlation between self-efficacy and task-performance $(G(r\sb{+})=.38)$, and a presence of significant systematic variance not accounted for. To account for within-group heterogeneity of individual correlations, I conducted a two-level theory-driven moderator analysis by partitioning k sample of correlations first according to the level of task complexity into low, medium, and high groups, and then into two classes according to the type of study setting. The magnitude of the average correlation between self-efficacy and task performance was the most pronounced at the low level of task complexity $(G(r\sb{1+})=.53)$, gradually declining as the task complexity approached medium $(G(r\sb{2+})=.38)$, and high levels $(G(r\sb{3+})=.24)$. These results were further moderated by the type of study setting which also revealed a pattern of pairwise differences among average correlations within each level of task complexity. New directions for future theory development and research are suggested, and practical implications of these findings are discussed.
