Abstract/Description: Non-suicidal self-injury (NSSI) is defined as the infliction of bodily harm in the absence of lethal intent and includes behaviors such has cutting, hitting, or scratching oneself (Nock, 2010). NSSI is prevalent among college populations, with one study reporting that 17% of students have engaged in self-injurious behavior at least once in their lifetime (Whitlock, Eckenrode, & Silverman, 2006). Importantly, research suggests that individuals who engage in NSSI are at an increased risk for suicidal thoughts and behaviors (i.e., suicidality; Van Orden, Witte, Cukrowicz, Braithwaite, Selby, & Joiner, 2010), but further research is required to understand why individuals who self-injure are at an increased risk for suicide. The purpose of the current study was to examine the relationship between self-injury and suicidality through the lens of the interpersonal theory of suicide (Joiner, 2005). Patients from a community mental health clinic completing a variety of self-report questionnaires assessing history of self-injury, depression, suicidality, and constructs related to the interpersonal theory (i.e., perceived burdensomeness, thwarted belongingness, and acquired capability for suicide). Results indicate that among individuals with a history of self-injurious behaviors, perceived burdensomeness, but not thwarted belongingness was associated with higher levels of suicidality above and beyond the acquired capability for suicide. Overall, results provide some insight into why some (but not all) individuals with NSSI are at risk for suicide.
