EXCERPT FROM THE RESEARCH ARTICLE Participants included 508 students (51% female) in Grades 6 (35%), 7 (30%), and 8 (35%) at the outset of the study attending a middle school in a moderately sized, middle-class community in the northeastern United States. Engagement in NSSI (non-suicidal self-injury) was determined by an affirmative response to the item "Have you harmed or hurt your body on purpose (e.g., cutting or burning your skin, hitting yourself, or pulling out your hair)?" For participants who endorsed engaging in NSSI, follow-up questions were provided to assess frequency of the behavior within the past year and to inquire whether the participant had made a suicide attempt in the past year (90% reported they did not, suggesting that NSSI indeed involves non-suicidal self-injury). It was anticipated that engagement in NSSI would be associated with engagement in other health-risk behaviors, including substance use, eating pathology, and sexual risk behaviors.
