Mental health and experience value at tourism destinations are multidimensional concepts with complex mechanisms. They are built on parallel bodies of research, especially for outdoor nature and adventure destinations. Their theoretical frameworks have the same components, connected in the same structures: place and activity, personalities, senses, emotions, and memories. The two distinct outcomes, health and experience respectively, depend on detailed differences in how these components are perceived and processed by individual tourists at particular destinations. Quantitative measures are already available for tourist personality and satisfaction, but not yet for tourist senses, emotions, memories, or mental health. Since each has multiple components, vector or matrix measures will be needed. We propose these as priorities for future research in destination marketing and management.
