Little is known about the drinking behaviors and perceptions of the peers facilitating campus alcohol interventions. The current study examined these trajectories in peer counselors (N = 12) providing personalized normative feedback interventions to undergraduates mandated to clinical services. Peer counselors completed four monthly self-assessments. In spite of facilitating interventions to reduce drinking and associated harms, peer drinking behaviors and expectancies did not change, although significant between subjects effects suggest various trajectories. Peer counselors did correct overestimates of binge drinking but progressively underestimated abstinence norms. Despite the lack of change in the peer counselor behaviors, the mandated clients significantly reduced their drinking, suggesting it may be more important to "Do as I Say" rather than as the facilitator does.
