This study examines how platform quality (PQ) and content quality (CQ) influence perceived individual benefit (PIB) of digital environmental campaigns, with student use behavior (UB) and student satisfaction (SS) serving as mediating mechanisms. Data were collected through a survey among university students, and structural equation modeling was employed to test the proposed relationships. The findings confirm that both PQ and CQ significantly enhance UB and SS, which in turn positively affect PIB. Specifically, UB exerts a strong direct effect on PIB (β = 0.423), underscoring the role of active engagement in shaping cognitive outcomes. SS also mediates the relationship, highlighting the importance of emotional involvement in fostering personal transformation. Subgroup analysis reveals that differences exist across academic years and between urban–rural backgrounds, reflecting the influence of digital access and academic maturity. Conversely, gender and training participation show no significant variation. Overall, the results emphasize that high-quality platforms and engaging content are critical drivers of effective digital campaigns, enabling students to internalize environmental responsibility. This study contributes empirical insights to the literature on digital environmental communication and provides practical implications for designing targeted, inclusive, and scalable campaigns. Future research should extend to larger and more diverse populations to validate and generalize the findings.
