SUMMARY:

This thesis investigates how the use of online social networks influences the life satisfaction of young Brazilian and Spanish users, based on Consumer Vulnerability Theory and Cognitive Dissonance Theory. Using a mixed-method approach (two quantitative studies and one qualitative study), it examines behavioral mediating variables (impulsive consumption, conspicuous consumption, and materialism) and psychological variables (social comparison, envy, narcissism, and body satisfaction). The hypotheses indicate that social networks act as catalysts for consumption behaviors and psychological processes that ultimately negatively impact life satisfaction. The research contributes to the reevaluation of classical theories in the digital context and provides insights for public policies and organizational practices aimed at youth life satisfaction.
