Maladaptive perfectionism and controlled motivation are vulnerability factors for burnout. This study examined the relationships between two aspects of perfectionism (high standards, discrepancy), four academic motivational orientations (intrinsic, identified, introjected, extrinsic), and academic burnout. The target population was 12th graders in South Korea, and a total of 950 participants were recruited using cluster sampling. Data were collected from three waves of longitudinal study. In particular, the mediating role of academic motivation (T2) in the link between perfectionism (T1) and academic burnout (T3) was tested using structural equation modelling. The results indicated that introjected motivation mediated the relationship between perfectionism and burnout. Specifically, both high standards and discrepancy were positively associated with introjected motivation, and in turn, introjected motivation was positively associated with burnout. The theoretical and practical implications of these findings are discussed.

Development of academic hatred was examined at four time points across 7 months among 1,015 South Korean high school students. A multilevel growth model showed that the baseline of, and change in, academic hatred varied across individuals and classrooms. At the individual level, gender, parents’ academic pressure, depression, and test anxiety were related to the initial level of academic hatred; gender and test anxiety were associated with a decrease in academic hatred over time. At the class level, lower socio-economic status and higher teachers’ autonomy support were associated with a lower baseline of academic hatred, and higher teachers’ autonomy support decreased academic hatred. Influence mechanisms of protective and risk factors on students’ academic hatred can be considered for strategic and policy interventions.
