Abstrakt
Global self-esteem is often used as a useful predictor of many socio-psychological outcomes such as well-being, happiness, life satisfaction, etc. [1]. Physical self-concept [2], a theoretical construct often discussed in kinanthropology/kinesiology research, is considered as an important source of global self-esteem.
There is however lack of information about relative contribution of specific sub-constructs of physical self-concept (sport competence, ...) to global self-esteem. Physical self-perception profile [2] and Rosenberg self-esteem scale [3] were used to measure the theoretical constructs of interest in a sample of 456 physically active university students.
Methods of correlation and regression analysis were used to analyse the contribution of specific sub-constructs of physical self-concept (sport competence, ...) to global self-esteem. Bivariate analysis has shown that all of the physical self-concept sub-constructs (see above) were significantly correlated with global self-esteem (r=0.35 to 0.49, p<0.05).
Multivariate regression analysis revealed however that only sport competence and body appearance significantly predict the global self-esteem in our sample when controlling for the other self-concept sub-constructs (standardized β = 0.21 and 0.33 resp., p<0.05). This result was stable even when adjusting for gender.
In conclusion, we have demonstrated that only specific components of physical self-concept contributed to global self-esteem in physically active university students. Future studies should examine whether this relationship holds also in different age groups or/and in a population of physically inactive individuals.
