Detailed Description
Firearm violence is a public health crisis in the United States, and new epidemiological data suggest we may have reached a new endemic level of firearm mortality in recent years. Youth are disproportionately affected by firearm violence, with those age 18-24 being demonstrably the highest risk group. This study will recruit 1,500 youth age 18-24 from urban emergency departments (EDs) in three broadly different locales-Flint, Philadelphia, and Seattle-and administer a baseline survey covering several domains of potential risk factors for future violence, and follow up with those youth at 6- and 12-months to ascertain the primary outcome-firearm violence involvement (as victim or perpetrator, including threats and sub-clinical injuries)-as well as the secondary outcomes: high-risk firearm behaviors, non-firearm violence, and violent injury. This work will generate new insights into the prediction of firearm violence, and will lay the ground for future research involving the development and testing of interventions for interpersonal firearm violence both by identifying potential high-leverage modifiable predictive factors, and by focusing on youth most in need of intervention.

Outcome Measures
Primary Outcome Measures
- Firearm Violence Involvement [1 Year After Baseline ED Visit]
The primary outcome for this study is firearm violence involvement, as perpetrator or victim. The primary outcome will be a binary indicator comprised of any affirmative response to the six questions asked as part of items 1-3, or any firearm events found from the objective chart review. Two self-reported measurements of firearm violence perpetration adapted from the modified conflict tactics scale (CTS-2). Two self-reported measurements of firearm violence victimization adapted from the modified conflict tactics scale (CTS-2). Presentation to the emergency department for a firearm injury (ICD-10 codes: X72-X74, W32-W34, X93-X95), measured based on objective chart review during the one year following baseline.
Secondary Outcome Measures
- Risky Firearm Behaviors [1 Year After Baseline ED Visit]
As established by Carter et al based on a) twelve items from the Tulane Youth Study that measure firearm carriage and discharge in high-risky situations (e.g., discharging a firearm while committing a crime, or carrying a firearm while using drugs); b) the four firearm violence perpetration/victimization outcomes listed under the primary outcome; and c) firearm violence threats (as victim or perpetrator), as measured by the modified conflict tactics scale (CTS-2)
- Non-Firearm Violence [1 Year After Baseline ED Visit]
22 self-reported measurements for non-firearm violence perpetration (11 for partner, 11 for non-partner) adapted from the CTS-2, 22 self-reported measurements for non-firearm violence victimization (11 for partner, 11 for non-partner) adapted from the CTS-2, and 6 items about fighting, adapted from the National Longitudinal Study of Adolescent Health.
- Violent Injury [1 Year After Baseline ED Visit]
Presentation to the emergency department for any violent injury, measured based on objective chart review during the one year following baseline.
