The phenomenon of impulsive purchasing of virtual items in online games such as Roblox is increasingly experienced by Generation Z and is often associated with low self-control and heightened Fear of Missing Out (FoMO) on social experiences. This study aims to examine the effect of self-control on fear of missing out among Generation Z Roblox players in Bekasi City. A quantitative approach was employed using simple linear regression analysis. The participants consisted of 184 Generation Z individuals selected through purposive sampling. Data were collected using self-control and online fear of missing out scales and analyzed with the JASP statistical application. The results indicate that self-control has a negative and significant effect on fear of missing out, suggesting that higher self-control is associated with lower levels of fear of missing out. However, most participants were classified in the moderate category for both self-control and fear of missing out, indicating that self-control alone was not sufficient to reduce fear of missing out to a low level. This study concludes that self-control plays an important role in suppressing fear of missing out among Generation Z Roblox players, although additional psychological factors are needed to further reduce this tendency.
