Non-suicidal self-injury is a risk factor for more severe self-injury and later suicide, yet is relatively under-researched in non-clinical populations. In order to prevent more severe self-injury and later suicide, understanding of non-suicidal self-injury is imperative. Two hundred eighty-nine young adults completed self-report questionnaires assessing the variables of interest. Of the sample, 47.4 percent reported a history of non-suicidal self-injury. Adaptive coping strategies protected those who were psychologically distressed from severe self-injury. However for those who reported greater distress, this protective effect was negated by heavy alcohol use. Coping skills training may serve to protect young people from self-injury, although those who are severely distressed may also benefit from strategies to limit alcohol use.
