However, this urge does not always lead to positive interactions at times, it manifests as cyberstalking behavior. This phenomenon is suspected to be associated with Fear of Missing Out (FoMO) and dark triad personality traits, two psychological factors that can trigger an obsessive drive to monitor other online activities. This study aims to examine the relationship between FoMO and dark triad personality traits with cyberstalking among Instagram users. Emerging adults were selected as participants, considering that this age group is in a developmental phase characterized by vulnerability to social pressure and identity exploration in the digital world. This research employs a correlational quantitative method. The respondents consist of 424 Instagram users from Java Island, selected through quota sampling. The instruments used in this study include the Cyberstalking Scale, an adopted version of the Short Dark Triad (SD3), and adapted version of the Online FoMO Scale. The collected data were analyzed using multiple linear regression tests and comparative analysis. The findings indicate a significant correlation between FoMO and dark triad personality traits with cyberstalking among emerging adult users. Additionally, a partial correlation was found between FoMO and cyberstalking, with regression coefficients of 0.301 and 0.272, respectively. The combined effective contribution of both independent variables to cyberstalking was 44.6% with FoMO contributing 24.8% and dark triad personality traits contributing 19.8%. No significant gender differences were found in cyberstalking levels. These results suggest that FoMO and dark triad personality traits can serve as predictors cyberstalking. The practical implication of this study highlights the importance of raising awareness among Instagram users, particularly emerging adults, to manage their FoMO and dark triad personality tendencies to prevent enganging in cyberstalking behavior. %K Cyberstalking, FoMO, Dark Triad Personality Traits, Pengguna Instagram, Emerging Adult %D 2025 %I UIN SUNAN KALIJAGA YOGYAKARTA %L digilib71298
