This paper presents a thesis project that aims to increase the digital skills of adolescents with a proposal for diagnosis and intervention of digital literacy. Adolescents have increased the use of interactive technologies and they commonly use the digital environment. However, this environment involves disadvantages and dangers that are of particular concern in the case of minors: exposure to pornography, cyberbullying, sexual harassment or grooming, sexting, contact with strangers… In this situation, we should not deprive adolescents of the use of digital technologies and interactive communication. The solution is to provide them with digital skills so they can use these tools safely.
