Students from underrepresented groups are increasingly enrolling in 4-year institutions, yet they may face additional stressors upon entering college compared to majority peers. Supportive relationships with peers, parents, and natural mentors may foster successful adjustment to college among such students. The current study examined patterns of social support among 340 underrepresented first-year students at an elite, predominantly White, public university. Latent profile analysis was used to characterize support networks. Four profiles of support emerged: Average Frequency Support (AFS), Higher Frequency Support (HFS), Lower Frequency Support (LFS), and Compensatory Mentor Support (CMS). Participants in the HFS profile started college with the highest levels of psychological distress and also demonstrated the greatest improvements in mental health. Results suggest that the most vulnerable students may require greater support to have a psychologically healthy transition to college.
