This paper describes an awareness campaign on the correct use of social networks. Based on the results of some surveys, it describes the reality of the situation and proposes methods and strategies to modify the use of social networks in adolescents. Extraction, transformation and cleaning of the data obtained from the surveys was carried out to generate a data repository. Once the data bank was obtained, an analysis was carried out, by applying data mining algorithms, such as those of association, classification and clustering, in order to obtain patterns of behavior. We compare these results to data received from subjects prior to the training in order to determine the efficacy of the training.
