Bifactorial analysis of the Rosenberg Self-esteem Scale and relationship between physical activity and self-esteem in adolescents

Self-esteem is a construct of great importance in adolescence that favors the health and psychological well-being of schoolchildren. In this paper, the two-dimensionality of the Rosenberg Self-Esteem Scale (RAS) is analyzed through confirmatory factor analysis, as well as the relationships between the practice of physical activity (PA), Global self-esteem, and the positive and negative dimensions of self-esteem. It was carried out in a sample of 429 students in the high school of the city of Seville (Andalusia). The instruments used were the Physical Activity Questionnaire in adolescents (PaqA, Martinez-Gomez et al., 2009) and the Rosenberg Self-Esteem Scale (EAR, 1965) version of Atienza et al. (2000). The results obtained allow us to accept the two-dimensionality of the scale, as well as good levels of global self-esteem and a tendency to better self-esteem in active adolescents. The practice of PA is associated with the Positive Self-esteem dimension, but not with Negative Self-esteem or Global Self-esteem.
