Abstract
We study the mental health of PhD students in Sweden using comprehensive administrative data on prescriptions, specialist care visits, hospitalizations, and causes of death. We find that about 7% (5%) of PhD students receive medication or diagnosis for depression (anxiety) in a given year. These prevalence rates are less than one-third of the earlier reported survey-based estimates, and even after adjusting for difference in methodology, 43% (72%) of the rates in the literature. Nevertheless, PhD students still fare worse than their peers not pursuing graduate studies. Our difference-in-differences research design attributes all of this health disadvantage to the time in the PhD program. This deterioration suggests doctoral studies causally affect mental health.
