PEMBELIAN KOMPULSIF ONLINE: MENGGAMBARKAN PERAN PERBANDINGAN SOSIAL KEUANGAN, FEAR OF MISSING OUT (FOMO) DAN MATERIALISME

This research provides a comprehensive overview of a study focusing on the relationship between financial social comparison, fear of missing out (FOMO), materialism, and online compulsive buying. The topic is relevant given the increasing intensity of social media use among young adults, which fosters psychological dynamics such as a tendency to compare one's financial situation with others and a fear of missing out on social experiences or material possessions. The research method used was a quantitative approach with a survey technique via an electronic questionnaire on Google Forms. The research sample was determined using purposive sampling, which included respondents who are active social media users and have made an online purchase within the last three months. A total of 159 respondents participated in the study. The data was analyzed using the Partial Least Square–Structural Equation Modeling (PLS-SEM) approach with the help of SmartPLS 3.3 software to test the validity, reliability, and causal relationships between variables. The results showed a positive and significant relationship between financial social comparison and FOMO on materialism, as well as between materialism and online compulsive buying. This means that the higher an individual's tendency to make financial comparisons and experience FOMO, the greater the likelihood they will adopt materialistic values. Ultimately, this materialistic orientation encourages a tendency toward online compulsive buying. These findings affirm the important role of psychological factors in shaping consumer behavior in the digital era. They also contribute to the development of literature on digital consumer behavior and self-control strategies in online shopping
