Reciprocal effects of self-concept and academic achievement in sixth and seventh grade

We aimed to (a) assess causal influences of three levels of self-concept on each other, (b) examine the relationship between each level of self-concept and academic achievement, and (c) compare the effect of self-concept on achievement with the effect of achievement on self-concept. In a two-year longitudinal study of 322 sixth and seventh grade students, influences over time between three levels of self-concept were weak. Zero-order correlations between self-concept and grades were positive and substantial, as in past studies. When using structural equation models, we found much weaker paths between self-concept and grades. Influences from self-concept to grades were very weak, but grades had a modest influence on subsequent discipline-specific self-concept. We conclude that past correlational studies have overstated the influence of self-concept on grades and of grades on self-concept.Financial support was supplied by the Life Cycle Institute, Catholic University.Received Ph.D. from Harvard University.
