The Relationship Between Self and Achievement/Performance Measures

This meta-analysis examines the relationship between the various self-measures and measures of performance and achievement. The statistical results of 128 studies are transformed to a common measure, namely, correlation coefficients. These studies represent a total sample of 202,823 persons and produce a data base of 1,136 correlations between self-ratings and performance measures. A range in the relationship of —.77 to .96 was reported with an “average” correlation of .21. It was found that this average relationship was modified by a number of variables. The more significant modifiers of the average relationship were the grade-level of subjects, socioeconomic status, ethnicity, ability of subjects, self-term used in the study, name of self-test used, type and name of performance/achievement measures, and the reliability of both the self-ratings and performance/achievement measures.
