This study is an attempt to determine if it is possible to establish causal direction between academic self-concept and academic achievement, focusing on whether academic self-concept and the subject-matter self-concepts of English and mathematics serve to generate academic, English, and mathematics achievements, respectively. This study of causal…

Data from 877 3rd, 7th, and 11th graders substantiated the multidimensionality of academic self-concept, as based on the Shavelson model, but yielded no support for increasing differentiation across age. Data also determined minor deterioration of hierarchical structure for early and late adolescents but no progressive pattern of weakening across…

This study represents the first to empirically validate the structure of social self-concept (SC) as proposed by the Shavelson model. For each of three age groups--preadolescents (252 3rd graders), early adolescents (290 7th graders), and late adolescents (335 11th graders)--analyses of covariance structures were used to test: (1) that social SC…

Results of an investigation of the construct validity of measurements of social and academic competencies of 175 3rd graders, 193 7th graders, and 159 11th graders made by the students themselves, teachers, parents, and peers suggest that researchers should consider making greater use of parent ratings for elementary school students.
