Vol. 7, Issue 2, Part I (2025)

The rapid expansion of social media has reshaped how individuals perceive and act on health and environmental issues. This comprehensive review synthesizes theoretical perspectives (TAM, TRA/TPB, VBN) and empirical findings (2010-2025) to examine how platform characteristics perceived usefulness, informativeness, credibility, interactivity, and privacy shape attitudes and how health and environmental consciousness mediate the attitude-intention link. The review integrates evidence across contexts, highlights methodological and conceptual gaps, and proposes a unified research agenda emphasizing cross-platform longitudinal designs and culturally sensitive measures.
