Association between depression and educational outcomes among young adults
BackgroundHigher academic performance is known to be negatively associated with the odds and severity of depressive symptoms. These results, however, were mostly obtained by using data on students from one educational organization or by relying on relative measures of academic performance such as grade point average. As a result, the relationship between academic performance measured by standardized tests and depressive symptoms at the population level is less known.MethodsWe use the data from the Russian study 'Trajectories in Education and Careers' (N = 4,400). This panel is nationally representative for one age cohorts and includes information on educational outcomes measured by an internationally recognized standardized test (PISA) at the age of 15 along with self-reported depression symptoms 6 years later (PHQ-9). ResultsThe prevalence of depression was 20% among women and 12% among men. We find no association between PHQ-9 scores for women and their PISA scores, however we find positive linear association for men (r = 0.15; CI95% = [0.10, 0.20]). This results in an increase of risk of being depressed from 4% for low-performing men to 17% for high-performing men. This result holds after controlling for the socioeconomic status of participants, the fact of studying at university, and the selectivity of their university.ConclusionsIt is generally believed that higher academic performance is negatively associated with depression. Our results indicate that the association might be more complex than has been previously thought and that high academic performance might be a risk factor for depression.
