Crisis and trauma are terms that have become alarmingly common in the United States. This chapter talks about crisis and trauma interventions which involve those of both an individual nature, students who do harm to themselves and of a mass nature, and students who do harm to multiple students or perpetuate events that threaten the safety of many students. Suicide is the second leading cause of death among college students. Risk factors for suicide include traumatic or stressful life events, prior attempts, isolation and lack of emotional support, and access to a suicide method. Safety usually involves a battery of activities: notifying parents or guardians, possible hospitalization, post hospitalization plan, medication, ongoing counseling, spiritual support for many, continued assessment, possible group counseling, support group, and so forth. The crisis management team (CMT) must communicate with campus administration, faculty, students, and legal authorities during crisis times.
