Abstract
Nowadays, people spend long periods on social media, ignoring the implications this carries in daily life. In this context, the concept of social media literacy, an emerging concept scarcely developed in the literature, is relevant. This study sought to analyze, descriptively, the main definitions and competences of the concept of social media literacy. The methodology included a systematic search of literature in the databases Web of Science, PubMed, and Scopus between 2010 and 2021, applying filters for English and Spanish, including only scientific articles. A total of 1093 articles were obtained. An article selection process took place, applying the inclusion and exclusion criteria, resulting in a total of 15 articles being selected. The findings indicate that the concept of social media literacy is based on media literacy to then integrate the characteristics and the implications of digital platforms. This is linked to the development of cognitive competences, where critical thinking, socio-emotional competences, and technical competences are fundamental, considering the social context. The development of socio-emotional competences stands out since social media are a frequent place of interaction between people.
