The objective of this research is to assess tourists' subjective and psychological well-being during and after their trips through a multiwave design. Drawing on self-determination theory (SDT) and attention restoration theory (ART), an integrated theoretical framework was proposed to examine the relationships among perceived attention restoration, social sharing satisfaction, psychological needs satisfaction, subjective well-being, and psychological well-being in the during-trip and post-trip encounters. This research contributes to the literature by offering new insights into the concept of social sharing satisfaction. It further enriches SDT and ART by synthesizing these two theoretical strands to enhance understanding of the linkage among attention restoration, social sharing / psychological needs satisfaction, and well-being at different travel stages. It also offers an alternative view on the dissipating effect of well-being after a trip by identifying the divergent effect of tourism on the change in subjective well-being and psychological well-being.
