Institutional Repository UIN Sunan Kalijaga YogyakartaHUBUNGAN ANTARA REGULASI DIRI DENGAN FEAR OF MISSING OUT (FOMO) PADA USIA DEWASA AWAL PENGGUNA MEDIA SOSIAL TIKTOKNIM.: 22107010110Erry SeptianingrumauthorFear of Missing Out (FoMO) is a feeling of anxiety that arises when individuals perceive that they are missing out on information, experiences, or activities enjoyed by others, particularly through social media. One of the internal factors presumed to be associated with FoMO is self-regulation. This study aimed to examine the relationship between self-regulation and Fear of Missing Out (FoMO) among emerging adults aged 18–40 years who use TikTok in DKI Jakarta. This study employed a quantitative approach with a correlational research design. The sample consisted of 189 emerging adult participants selected using a purposive sampling technique. Data were collected using the Fear of Missing Out Scale and the Self- Regulation Questionnaire (SRQ). Data were analyzed using the Pearson Product-Moment correlation test. The results indicated a significant negative relationship between selfregulation and Fear of Missing Out (FoMO) (r = -0.149; p = 0.020). These findings suggest that higher levels of self-regulation are associated with lower levels of FoMO. Self-regulation contributed 2.2% to FoMO, while the remaining 97.8% was explained by other factors not examined in this study.
