Objective: Examine associations between political diversity, health, and stress in a student sample for whom examining political biases is necessary. Participants: Graduate students in mental health (N = 512) from July 2017 to June 2018. Methods: Participants completed an online survey of political views, health, and stress. Descriptive statistics reported sample characteristics; stepwise regressions tested whether political affiliation and perceived political majority/minority status predicted health and stress. Results: Students identified primarily as liberal, and perceived their counterparts as liberal. Liberal political identification generally predicted more stress and poorer health in several domains; however, those identifying as most politically conservative also reported relatively high stress. Conclusions: Liberal academic environments may relate to stress for those who identify as most politically conservative, while also not protecting liberals against broader sociopolitical stress and related health sequelae. Graduate students in mental health may benefit from increased curricular and supervisory focus on political diversity and related biases.
