Self-esteem can be considered one of the pillars on which personality is built, and one of the most powerful predictors of the degree of psychological adjustment during adolescence and adulthood (DuBois, Bull, Sherman, & Robert, 1998; Parra, Oliva, & Sánchez-Queija, 2004). This is why self-esteem has awakened and continues to awaken the interest of researchers. Today, it is possible to appreciate in the scientific literature how it is a subject that produces a considerable number of studies, since there are many aspects of self-esteem and many variables with which it is related. If we take into account that self-esteem can act as a prism through which each individual sees himself and the world around him, we will consider the repercussions that this concept has on our lives.

We must keep in mind that a positive self-esteem allows the individual to feel capable of overcoming the challenges that arise in daily life, allowing a positive assessment of himself and his capabilities, while on the contrary, a low self-esteem leads to a feeling of inability that leads the person to self-limit himself and fail. Self-esteem plays a mediating role in the perception of experiences, affecting, positively or negatively depending on the sense of self-esteem, mental health, social adaptation and school environment.

Regarding mental health, a positive self-esteem facilitates the individual a good emotional adjustment, while a negative self-esteem is associated with anxiety problems, depression and eating disorders among others.
