This research aims to explore how FoMO affects Gen Z's communication patterns and social interactions, with a focus on the TikTok platform. FoMO is defined as anxiety that arises from the fear of missing valuable moments or not engaging in activities that are considered important by the social environment. The research used a qualitative approach with descriptive methods, involving five Gen Z respondents aged 18-23 who actively use social media. The results show that FoMO affects Gen Z's behaviour in several aspects, such as excessive duration of social media use, smartphone dependence, and pressure to always follow trends or viral content. TikTok, as a short video- based platform, reinforces this phenomenon with algorithms that encourage intensive engagement. In addition, FoMO also impacts Gen Z's communication patterns, which tend to be more virtual than face-to-face, thus affecting the quality of their social interactions in the real world. This research highlights the importance of understanding the psychological and social impacts of FoMO in the context of digital culture. The findings can be used to design interventions to reduce the negative impact of FoMO and encourage healthier social media use in the digital culture.
