Alcohol and substance disorders. Life-threatening eating disorders. Suicidal behaviors. Students' mental-health needs continue to garner considerable attention at colleges and universities--as well as among the public and in the press when a high-profile tragedy occurs. Institutions and the boards of trustees that govern them are challenged with creating and supporting top-quality campus services and administrative structures that respond appropriately to those needs. However, many institutions do not have the resources in place or a comprehensive plan for dealing with the myriad of mental-health issues that their students grapple with today. A fundamental role of any board of trustees is to be a good steward of institutional resources, and no resource is more important than the students themselves. Boards can promulgate and reinforce five key strategies that will help their institutions encourage student mental health and create a campus culture that sustains it. Those strategies are to: (1) adopt a public-health approach; (2) support adequate counseling and mental-health services; (3) develop outreach programs to get students to seek help; (4) create structures that coordinate support for students; and (5) attend to the physical environment of the campus and surrounding community. In this article, the author describes each strategy in more depth. (Contains 4 online resources.)
