This study employed the peak-end rule and the Kano model in the assessment of user satisfaction during the product-use experience. Because they reflect different aspects of user satisfaction, we investigated the similarities and differences between the two approaches and integrated them in the analysis of the product-use process. We find that the emotional component of the peak-end rule, which directly indicates the important emotions of the users, and the usability component of the Kano model, which provides useful information on product qualities, are particularly useful in assessing the product-use process. We believe that integrating these two methods generates abundant, specific, and useful knowledge that designers can use to more fully understand the user experience.

To regain overall well-being in the post-pandemic era, the priorities should not be only economic growth but also human physical and mental health. This study investigates how to incorporate the concept of well-being into the circular economy to facilitate the pursuit of individual/personal and social growth, and sustainable consumption. We begin with a systematic search of the literature on well-being and sustainable product–service systems, model the well-being components in peer-to-peer (P2P) sharing and reuse platforms, and propose design guidelines for platform development. According to our findings, (1) allocentric well-being components (such as gratitude, contribution, and altruism) serve as the antecedents of sharing behaviors, while egocentric components (such as pleasure and attachment) serve as the consequences, and (2) information sharing is crucial to initiating the flow of well-being perceptions and sustainable sharing and reuse behaviors. Based on the findings, we suggest a data-driven approach and active inference theory to facilitate related studies. This study sheds light on the potential to develop well-being within the circular economy and facilitate the sustainable working of the sharing and reuse ecosystem.

Humans pursue well-being in their lives. Well-being encompasses positive emotions, life satisfaction, healthy functioning, meaning of life, and self-growth. In ancient times, sharing was an intimate behavior that consolidated communities and led to an ideal life, which refers to well-being in the present. Sharing economy sheds light on a novel business model in which people can develop their well-being while sharing resources/goods and services among strangers. However, prior research shows that users participate in the sharing economy because of self-interest rather than social interaction or sustainability. Sustainable well-being is important not only for us but also for our communities and our planet. This study investigates how the components of well-being can be built into a sharing economy and foster users to pursue it in the long-term. It reviews and synthesizes prior studies to (1) elucidate the components of well-being in the peer-to-peer (P2P) sharing economy, (2) model the sharing ecosystem with components of well-being from a global perspective, and (3) discuss the design solutions for a P2P sharing platform to facilitate well-being. Furthermore, it provides examples of practices to illustrate the proposed model. We believe this study not only motivates platformers to consider users’ well-being but also promotes sustainable functioning of the sharing ecosystem.
