Additionally, we posit that a grateful climate, functioning as a socio-cultural structure, plays a crucial cross-level moderator. A total of 203 athletes from 32 sports teams were included in the analysis. Employing a time-lagged design, our results reveal a significant predictive relationship between perceived coach autonomy support and changes in subjective vitality. Moreover, a noteworthy cross-level moderating effect of the grateful climate emerged. In teams characterized by a high grateful climate, the relationship between coach autonomy support and athlete subjective vitality was significantly stronger; and such an effect is not validated in teams with a low grateful climate. These findings are consistent with our expectations, affirming not only the replication of previous research but also emphasizing the importance of a grateful climate as a cultural structural factor in this context. ARTICLE HISTORY Received 5 January 2024 Accepted 14 March 2024 KEYWORDS Self-determination theory; broaden-and-build theory; gratitude; adolescent Subjective vitality has been a crucial concept that researchers have focused on for the past several dec- ades. Ryan and Fredrick (1997) defined vitality as the energy for daily living available to everyone, encompass- ing more than just physical vigor but also simultaneous presence of enthusiasm and spirit. As a series of studies have unfolded, subjective vitality has gained increasing attention across various fields, including clin- ical psychology, consumer psychology, developmental psychology, educational psychology, and sports psy- chology. Previous research has indicated that having higher levels of subjective vitality greatly benefits an individual's physical and mental health. Consequently, researchers have been actively seeking potential factors to enhance individuals' subjective vitality over time (e.g. Chen et al., 2022; Kinnaifick et al., 2014; Patrick et al., 2000). From this perspective, this is even more crucial for athletes who face intense training
