Involvement in violence was examined on the basis of the following question: “During the past 12 months, how many times have you attacked someone with the intent to seriously hurt them?” Consistent with recent NSDUH-based studies, youth reporting one or more instances of violent behavior were coded as 1 and all other youth coded as 0 (Salas-Wright et al., 2013 and Vaughn et al., 2014). This measure of violence is the only violence-related question that is administered to both the adolescent and young adult subsamples in the NSDUH. The NSDUH does not include past 30-day measures of violence.
