The mediating role of marine environmental responsible intention (MERI) is also examined. The research involved 320 responsible Thai SCUBA divers’ in Haad Chao Mai Mai Marine National Park. The analysis, conducted using structural equation modeling (SEM) with a two-stage approach, yielded a well-fitting model that aligns with the empirical data (x2/df = 1.758, GFI = 0.973, AGFI = 0.925, CFI = 0.993, RMSEA = 0.049, and RMR = 0.013). The study’s findings indicate that MERI plays a dual role in mediating the relationships within the model. It partially mediates the connection between EA and MERB and fully mediates the relationship between SDS and MERB. This highlights the importance of promoting responsible behavior among SCUBA divers. Marine destination managers and SCUBA diving businesses can contribute by offering meaningful, low-impact diving experiences. Similarly, government agencies and policy makers can support these efforts through responsible campaigns and events, ultimately enhancing MERB.258 leavesapplication/pdfengThis work is licensed under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License.Marine environmentEnvironmental awarenessMarine ecologyEnvironmental protectiontext::thesis::doctoral thesis10.14457/NIDA.the.2024.29
