Physical Self, Social Self, Psychological Self, and Moral Self in Reflecting Self-Concept

The purpose of this study is to test the validity and reliability of the self-concept as a construct and test aspects and indicators that can form this construct. Self-concept is measured by four aspects, including physical self, social self, psychological self, and moral self. The population in this study are all students of grade XI with a total sample of 60 students. The sampling technique used is simple random sampling. The data collection method is a self-concept scale. Research data were analyzed using Structural Equation Modeling (SEM) through the SmartPLS version 3.28. Based on the results of data analysis, the aspects and indicators that made up the construct of self-concept were valid and reliable. The dominant aspect reflecting the construct of self-concept is the social self with a loading factor of 0.806, and the weakest aspect reflecting the construct of the self-concept is the physical self with a loading factor of 0.703. This shows that all aspects and indicators are able to reflect and shape the construct of self-concept. Thus, the measurement model can be accepted because theories that describe self-concept fit with empirical data obtained from the subject.
