Self-concept in this article is considered in physical education, with the physical self-concept being in the foreground, and it is analyzed in this quantitative study to determine whether it is related with socio-economic environment and parental styles, focusing on primary education students in the Region of Murcia. Primary education students are in a critical period for the development of self-concept. To assess self-concept levels, socio-economic and cultural environments as well as parental socialization styles, the PSPP, NSE and ESPA29 questionnaires were respectively used. They were used to collect data from 937 students across various educational centers in upper courses (4th, 5th and 6th grades of primary education) to uncover realities in child society and their relationship with self-concept. In the first objective, parental socialization styles are shown to be related with self-concept. However, in the second objective, it is seen that the socio-economic environment is more related with self-concept than parental styles. Finally, the results of the third objective show that there is indeed a relationship with the socio-economic environment and the student body self-concept, both at the family level and for fathers and mothers independently. It is important to consider both the parental styles and the socio-economic environment in which primary education students develop for the development of self-concept. Additionally, educational implications and new lines of research are suggested in this topic.
