Background: Between 9.5% and 31.3% of college students suffer from depression ("American college health association national college health assessment II: reference group executive summary spring 2013." "Amer. Coll. Health Assoc." 2013; Eagan K, Stolzenberg EB, Ramirez JJ, Aragon, MC, Suchard, RS, Hurtado S. "The American freshman: national norms fall 2014." "Higher Educ. Res. Inst."; 2015). Universities need to understand the factors that relate to care-seeking behavior. Objective: Across 3 studies, to relate attitudes, social norms, and perceived behavioral control to intention to seek mental health services, and to investigate barriers to care-seeking. Participants: University college students (N = 845, 64% female, 26% male, and 10% unspecified). Methods: New measures were created in Studies 1 and 2, and were examined using structural equation modeling in Study 3. Results: Partially consistent with the Theory of Planned Behavior (Ajzen, I, Fishbein, M. "Understanding Attitudes and Predicting Social Behavior." Englewood Cliffs, NJ: Prentice-Hall; 1980), a model with an excellent fit revealed that more positive attitudes about care and higher perceived behavioral control directly predicted higher intention to seek mental health services. Conclusions: Educating college students about mental health disorders and treatments, enhancing knowledge about available services, and addressing limited access to long-term care might improve treatment rates for students suffering from depression.
