This project was a study of the validity and reliability of adapted versions of Fox and Corbin’s (10) Physical Self-Perception Profile (PSPP) and Perceived Importance Profile (PIP) for use with seventh- and eight-grade students. The Children’s PSPP and PIP (C-PSPP and C-PIP) questionnaires were completed by 505 students. Results supported the reliability and the construct and concurrent validity of the C-PSPP scales. Factorial validity of the C-PIP was not demonstrated. Similar to Fox and Corbin’s (10) results, regression analysis revealed that a large proportion of the variance in general physical selfworth (PSW) was explained by the C-PSPP scales. The hypothesis that PSW mediates between general self-worth (GSW) and the four C-PSPP scales in a hierarchical arrangement was also supported. Failure to psychologically discount the importance of perceived incompetence in specific areas impacted global self-worth. Correlations with physical fitness test scores provided evidence of concurrent validity of the C-PSPP scales.
