RESUMEN
Objective: The first year of college is a time of major changes in social dynamics, raising questions about ways to promote students' mental health. We examined longitudinal associations between students' sense of belonging, imposter syndrome, depressive symptoms, and well-being. Participants: Fifty-eight first-year college students at a university in the United States participated in the study. Methods: Students completed questionnaires during the first 6 months of college (T1) and at the end of the academic year (T2). Results: Greater sense of social and academic belonging was correlated with lower imposter syndrome, depression, and greater well-being at T1. Accounting for T1 measures, lower imposter syndrome predicted greater well-being but not depression at T2. Accounting for T1 mental health, belonging was not a significant predictor of depression or well-being at T2. Conclusion: Increasing sense of belonging and addressing imposter syndrome early in the transition to college may be critical in promoting mental health.
