Psychological suzhi and academic achievement in Chinese adolescents: A 2-year longitudinal study.

Four distinct developmental trajectories of academic achievement were identified (i.e., high-positive growth, middle-negative growth, low-stable, and lowest-stable) that were significantly predicted by different levels of psychological suzhi, particularly the dimension of cognitive quality. Cognitive quality was strongly associated with the initial academic achievement values in the high-positive growth group and linked to achievement rate (decreasing) in the middle-negative growth group. However, individuality quality and adaptability quality had a buffering effect on the rate of achievement decreasing in the middle-negative growth group. This study not only highlighted the promotive role of high cognitive quality on high levels of achievement (static) but also indicated the protective role of non-cognitive factors (i.e., individuality and adaptability) against a decreasing rate of academic achievement (dynamic).
