  • This study extends support for the construct validity of the three strongest physi­cal self-concept measures for 395 Israeli university students (60% women) aged 18 to 54, demonstrating a new extension of the multitrait-multimethod (MTMM) design that incorporates external validity criteria and a test of jingle-jangle fal­lacies. Structural equation models of this MTMM data confirmed the a priori 23-factor structure of the three instruments, and the convergent and discriminant validity of factors from each instrument in relation to those from the other instru­ments. There were few age effects, whereas gender differences were smaller than expected and stable over age. In support of the known-group-difference approach, physical education majors had systematically higher physical self-concepts than management majors. Relations of body image to self-concept factors supported the convergent and discriminant validity of the physical self-concept factors and the separation of body fat from physical appearance self-concepts, but having a more obese body was not significantly related to health self-concept or global self-esteem factors.
