In an attempt to improve the correlation between teacher ratings and self-concept scores, the McDaniel-Piers Young Children's Self Concept Scale, used by McDaniel and Leddick (l978), was revised to more adequately measure a single dimension of self-concept. A 20 item Teacher's Estimate Form (TEF) was developed on which teachers rated children on each attitude or behavior included in the revised self-concept scale. Seventeen elementary teachers and 395 children participated in the study. All teachers completed the TEF for each of their pupils and then administered the revised self-concept scale to their classes. Two months later, the self-concept scale was readministered by the teachers to their pupils. Correlation coefficients were computed between the TEF and the first and second administration of the self-concept scale. Results showed only little improvement over the earlier findings of McDaniel and Leddick (1978) when using a more heterogenous measure of self-concept and a more global rating by teachers. However, the maximum correlation between the teacher ratings and the self-concept scores reached .65 -- an improvement over the earlier findings (.58). (Author/MP)
