A large survey by Trellis Strategies finds loneliness and isolation are widespread among undergraduates, with more than half reporting they feel 'sometimes' or 'always' lonely and loneliness linked to much higher rates of anxiety and depression. The research ties social isolation to lower retention and increased stop‑outs. In response, student organizations and national nonprofits are expanding partnership models: The Jed Foundation is working with fraternities on prevention and peer support programs to tackle hazing, substance misuse and emotional well‑being. Colleges are increasingly viewing social connectedness and peer networks as urgent retention levers, not just student welfare concerns.
