Three essentially parallel forms of the Dimensions of Self-Concept scale were factor analyzed using three samples of students: one elementary school sample, one junior high school sample, and one high school sample. Results are interpreted in terms of the reliability and validity of the scale. (Author/JKS)

The construct validity of a 17-item exploratory academic self-concept subscale derived from the Piers-Harris Chidlren's Self-Concept Scale was investigated. Its empirical factor structure and its correlation with two other academic self-concept instruments were analyzed. Research use only is recommended pending rewriting of this exploratory…

The development and construct validation of the Dimensions of Self-Concept (DOSC), Form H, are described. The 20-item subscales of the preliminary research form furnished parallel estimates of reliability ranging from .83 to .91. The five subscales show promising construct validity, as evidenced by their factor structure. (Author/BW)

For each of two revised forms of the Dimensions of Self-Concept measure (intermediate and secondary forms), statistical information is presented concerning the intercorrelations of each of five factor scales, the reliability and standard error of measurement of each scale, and the results of item analyses.

An experimental test was developed for the measurement of self-concept in an employment setting. Administering this six-factor Dimensions of Self-Concept test to 201 employees in an electronics/computer company resulted in a determination of internal consistency and reliability sufficient to justify testing a revised version based on statistical…
