Co-rumination, a social process between two friends, is defined as the frequent and excessive discussion of personal problems. Like body image and alcohol use, it is one of those complicated issues embedded in larger cultural realities, which makes it universally recognizable. On campus, co-rumination has deleterious side effects: it challenges students' mental wellness, healthy friendships, capacity to focus on learning, and the ideals of a supportive campus community. It is not surprising, for instance, that college students considering transferring out of their institution often engage in co-rumination. Knowledge about co-rumination can help educators support students personally; it also helps develop their sense of responsibility and concern for others, especially friends, and can support a focus on learning, particularly successful problem solving. After a short summary of the research on co-rumination and its five characteristics, this article offers an example of a process used at the University of Richmond to help educators identify its occurrence and support students as they move to adopt more positive approaches to conversation and problem solving.
