The development of technology has also helped the development of digital media which have become a very important factor in the socialization of children and youth. The media have a role in conveying values, shaping lifestyles and identities, and serve to inform the public. With the advent of digital media and access to the Internet by a large number of people, the amount of informations we receive from the media has also increased. Even at school, students spend time on digital media, whether it's a phone call, listening to videos,playing games so the question is whether it affects the social status of children, or their social skills. The aim of this research was to examine which digital media and video games are used by children and whether their use is related to social development. The research was conducted on a sample of 259 students from 2nd to 8th grade of primary schools. For the purposes of the research, a questionnaire was compiled consisting of 5 parts: general data, a scale of perceived social competence, a scale of social self-efficacy, a questionnaire on the use of digital media and a questionnaire on the frequency of playing video games. The results of the research showed that lower grade students are more socially competent and girls are more socially competent than boys. Boys spend more time playing video games, while girls use digital media for social networks and to communicate through various applications. However, older students do not spend as much time playing video games as lower grade students do. Parental control has been shown to be positively related to social self-efficacy - students who have higher parental control in the use of digital media and video games have higher social self-efficacy.
