The factor structure of five self-concept scales from a hierarchical, multidimensional theoretical model was investigated. The Coopersmith Self-Esteem Inventory, Multidimensional Self Concept Scale, Piers-Harris Self-Concept Scale, Self-Esteem Index, and the Tennessee Self-Concept Scale were administered to 221 students in Grades 5 through 8 in a counter-balanced administration format. The five scales each yielded strong general factors and six dominant factors that coincide with the proposed theoretical model, which reflects social, affect, competence, academic, family, and physical self-concepts.
