This mata-analysis examined the relationship between self-efficacy and perf
ormance in sport. Based on 45 studies (102 correlations), the average corre
lation between self-efficacy and sport performance was .38. Given the heter
ogenity of findings, follow-up univariate and multivariate moderator analys
es were conducted. Results indicated that the most important moderator was
concordance, thereby highlighting the importance of matching the self-effic
acy measures, the types of performance measures, the nature of the task, an
d the time of assessments. These variables accounted for approximately 44%
of the variance in the self-efficacy-performance relationship. Practical im
plications of the findings are discussed.
