Suicidal and nonsuicidal self-injurious behaviors among youth are mul-tifaceted events, emerging from biological, cultural, sociological, psy-chological, and interpersonal factors. An understanding of how these factors, including depression, contribute to self-injurious behaviors among youth is critically needed given the magnitude of these behaviors. Seventeen hundred 15-to 19-year-olds, killed themselves in 2004, more than died from cancer, heart disease, birth defects, chronic respiratory disease, HIV, stroke, and diabetes combined (CDC, 2005). An additional 1.5 million high school students attempted suicide (Eaton et al., 2006), and up to 2.1 million high school students engaged in nonsuicidal self-injury (NSSI; Muehlenkamp & Gutierrez, 2007) in the past year. The goal of this chapter is to provide a review of the risk and protective factors for youth suicide and NSSI. In addition, treatment implications of the research fi ndings discussed will be highlighted.
