Abstract
This study investigated the construct validity of four self-report, self- concept instruments: Bledsoe Self-Concept Scale (BSCS), Children's Self-Concept Scale (CSCS), Self-Esteem Inventory (SEI) and Purdue Self-Concept Scale (PSCS). In assessing the self-concepts of 175 fourth-grade children the convergent validity of the tests was not established. No significant correlations were found between any of the instruments and the Behavioral Rating Form (BRF) even though the instruments correlated significantly with each other. When considering discriminant validity, only the BSCS (in the case of the total sample) and the females fulfilled the criteria of a significant negative correlation with the Children's Manifest Anxiety Scale (CMAS), and a nonsignificant correlation with the Children's Social Desirability Scale (CSDS). Factor analysis extracted three interpretable factors: perceived adjustment, social desirability, and complexity. The findings suggest that anxiety and self-concept scales may be measuring the same underlying factor or construct and that sex may be an important variable affecting response style.
