Slow lifestyles have become a way for individuals to reduce the amount of stress in their lives. Moreover, along with wellness and slow food, slow life seeking is emerging as an area of study, though little research has been studied at Slow Life Festivals (SLFs) associated with consumers wellness pursuits, slow life seeking, and perceptions of slow food. To address this gap, this study examined visitors decision-making processes using an extended theory of planned behavior (ETPB) by incorporating wellness pursuit, slow life seeking, and perceptions of slow food at an SLF. Thus, this study developed a theoretically comprehensive framework by applying field survey. Results revealed significant impacts of visitors wellness pursuits and slow life seeking on their decision-making, indicating that wellness and slow life were important factors to consider for SLF management. The research further identified the perception of slow food as a mediator in predicting behavioral intentions. Results further demonstrated a strong relationship between wellness pursuit and perception of slow food for highly attached visitors while revealing a significant relationship between slow life seeking and perception of slow food for less attached visitors. Consequently, this study shed significant light on our understanding of why visitors intend to revisit SLFs.
