Extensive media coverage of the suicide deaths of several gay and lesbian youth has highlighted lesbian, gay, bisexual, and transgender (LGBT) youth as a population at-risk for suicide. In addition, it has caused colleges and universities to address mental health and suicide behavior among this very diverse college population. One issue that researchers, administrators, and students alike must address is how to delineate the membership of this population. Depending on whom one asks, the letters involved can be as long as LGBTTTQQIPAAA. The literature reviewed for this chapter used a variety of terms from LGBTQ to sexual minority and used various definitions to determine membership within these groups. The authors use the term "LGBT" unless they are referring specifically to a subpopulation within this group. In this chapter, they review the research about LGBT suicide, risk factors and protective factors for LGBT students, and bullying and cyberbullying. The chapter concludes with a description of how one institution addressed suicide prevention for LGBT students. (Contains 1 table and 1 figure.)
