In this study, we used a longitudinal survey of two time-points to investigate the relationship between motivation instability and type of motivation level toward university learning using a cross-lagged panel model. We measured four types of motivation level based on self-determination theory. A total of 127 Japanese students from two universities participated in two longitudinal surveys; their data were used in the analysis. We investigated the relationship between motivation instability and motivation level by employing the cross-lagged panel model, and found that intrinsic regulation at Time 1 was positively related to the instability of motivation at Time 2, while identified regulation at Time 1 was negatively related to instability of motivation at Time 2. These results indicate that two processes may exist: one where instability of motivation increases depending on the level of motivation, and one where it decreases. Moreover, instability of motivation at Time 1 was positively related to the identified regulation and introjected regulation at Time 2, although the values of the path coefficients were very small. Finally, instability of motivation at Time 1 was positively related to the instability of motivation at Time 2. Based on the results of this study, we discuss the relationship between motivation level and instability in university learning.
