ABSTRACT
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. 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 nonsuicidal 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.
