This master’s thesis examines the impact of the social media platform TikTok on the formation of young people’s identity and body image. The theoretical section establishes the theoretical foundations, specifically the definition of adolescence, identity and its formation during adolescence, as well as the body and body image. It also examines the influence of the media and media images on individuals, with an emphasis on social comparison, idealized images, and the formation of perceptions of appearance. The paper then presents the development of TikTok and the characteristics of the platform that contribute to its popularity, with particular emphasis on the content recommendation algorithm, personalization, short videos, and interactive mechanisms. A separate subsection is also devoted to TikTok as a space for information, inspiration, and participation.
As part of the empirical component of this master’s thesis, a qualitative study was conducted, specifically a semi-structured interview with 14 adolescents aged 14 to 25. The aim of the study was to examine the role of TikTok in the lives of adolescents and to determine how its use influences the formation of identity and body image. Particular attention was paid to the various ways in which the social network is used, the experience of idealized body images, and the influence of interactive mechanisms. The analysis of the adolescents’ responses was structured around six research questions, which enabled a comprehensive examination of TikTok use and the experience of its effects.
