Due to the growing competitive challenges, athletes' mutation between clubs has emerged an area of interest within career development. However, studies aimed at analysing this specific process of adaptation to clubs that lead to success or failure in such career mutations are seldom. We developed a comprehensive understanding of the psychological mutation processes to clubs using a narrative level of McAdams' model of personality. The qualitative method approach used in the Big Three narrative framework (McLean et al., 2019) and good life stories standards (McAdams, 1996) were applied to uncover the components of the narratives of twenty professional basketball players during mutation between clubs. The current study sort to test the links between these narrative components and athlete successful club to club mutation (CCM-successful). On average, the results showed that the participants experienced richer narratives as compared to general population t (17.08) = -1.48, p < .05. Narratives in the CCM-successful were also richer (Mean = 2.83, SD = .16) as compared to narratives of the CCM-unsuccessful (Mean = 1.63, SD, = .36). The overall club mutation success correlated positively with exploratory processing, meaning-making and agency narrative components. These results suggest that when athletes develop active attitudes seeking for solution and sharing their experience with others, they may build the conditions of adaptability that corresponds to a successful outcome for their mutation. The participants exhibited flexible and proactive behaviours which rendered possible the appropriation of the elements in the environment that favour a positive experience of mutation.
