In Study 1, a sample of tennis players ranked at the national level (n = 173) completed a French version of the Situational Motivation Scale the day before a tennis competition. Results revealed the presence of a three-cluster solution. Differences among clusters on subsequent sport performance were significant. Specifically, athletes with the least self-determined motivational profile obtained the lowest levels of performance. Study 2 (n = 319) replicated the findings of Study 1 with a larger sample of national level tennis players. Overall, these results suggest that it is useful to analyze individuals' situational motivational profiles using a cluster analysis to understand the complex link between motivation and performance.
