Resumo
This study investigates the factors that shape digital privacy decisions among Brazilian adolescents when using online platforms. Grounded in the Antecedents–Privacy Concerns– Outcomes (APCO) model, the research examines the role of Fear of Missing Out (FOMO) as an emotional antecedent, alongside online privacy cognitions, trust beliefs, risk beliefs, and intention to continue using such platforms. A quantitative research design was employed, based on a survey administered to adolescents aged 12 to 17 enrolled in public and private schools in Brazil, using internationally validated measurement scales. We analyzed data through Partial Least Squares Structural Equation Modeling (PLS-SEM). The results indicate that FOMO positively and significantly influences online privacy cognitions, which, in turn, directly influence trust beliefs in digital platforms. Trust reduces risk beliefs and increases intention to use, whereas risk beliefs did not significantly affect behavioral intention. These findings suggest that adolescents' digital decisions are shaped by a cognitive–emotional configuration in which rational assessments coexist with social and emotional pressures. The study contributes to the information systems literature by extending the APCO model through the empirical incorporation of an emotional antecedent and by offering practical insights for developing educational and regulatory strategies to strengthen the protection of adolescents' personal data.
