Abstract
The feasibility of using self-concept measures along with intelligence measures to improve the prediction of achievement was explored. Two self-concept tests, an intelligence test, and an achievement test battery were administered to 47 male and 49 female sixth graders. Achievement was found to be related to academic success self-concept, but not to physical maturity, peer relations, or school adaptiveness self-concepts. Achievement in the content areas of reading, language, and mathematics was most directly related to self-concept measures that were specifically reflective of academic success in these content areas. In each of these areas, the combination of intelligence and the related academic success self-concept measure accounted for more achievement variance than did intelligence alone. This last finding was interpreted as evidence suggesting that content area specific self-concept measures might facilitate the prediction of academic success, and researchers wishing to control for self-concept in studies of academic achievement should use measures of self-concept that are specifically reflective of academic success in the content area being investigated.
