The purpose of this study is to construct a structural equation model to examine the links among attitudes, values, and behaviors pertaining to sustainability, participation in outdoor recreation as well as gender and tendency to follow mass media for university students. The model hypothesized that tendency to follow media and gender was significantly correlated with attitudes, values, and behaviors pertaining to sustainability as well as participation in appreciative outdoor recreation. Furthermore, behaviors could be predicted by attitudes, values, and outdoor activities. The model also hypothesized that attitudes may act as the significant predictors of values and outdoor activities.
