Outcome Measures
Primary Outcomes (1)
Firearm Violence Involvement
The primary outcome for this study is firearm violence involvement, as perpetrator or victim. This will be measured in part by the Conflict Tactics Scale 2, as established by Straus et al. CTS-2 is comprised of a 6-point scale, measuring how often the respondent has experienced each type of violence, ranging from never to more than 20 times. The primary outcome here will be a binary indicator comprised of any affirmative response to the questions asked as part of items 1-3 below, or any firearm events found from the objective chart review. 1. Two self-reported measurements of firearm violence perpetration adapted from the modified conflict tactics scale (CTS-2). 2. Two self-reported measurements of firearm violence victimization adapted from the modified conflict tactics scale (CTS-2). 3. 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.

Eligibility Criteria
Youth aged 18-24 seeking care at the Emergency departments of Hurley Medical Center, the Hospital of University of Pennsylvania, Penn Presbyterian Medical Center, or Harborview Medical Center
You may qualify if:
- Flint, Philadelphia, or Seattle Youth between the ages of 18-24 seeking care for any reason at Hurley Medical Center, the Hospital of University of Pennsylvania, Penn Presbyterian Medical Center, or Harborview Medical Center Emergency Department
- Can provide consent for the study
You may not qualify if:
- Do not understand English (\<1% in prior work)
- Unable to provide consent due to mental status (e.g., alcohol intoxication, acute psychosis) or medical instability.
- ED visit requiring intensive psychosocial services (e.g., sexual assault, psychosis, active suicidal ideation, or child abuse)

After study completion, de-identified data will be curated and uploaded through the Inter-University Consortium for Political and Social Research (ICPSR) run through the University of Michigan. ICPSR stores, curates, and provides access to data generated through social research studies in service to open science, which acts in service to optimized data sharing, rigorous detailing of study methods and citations for measures, and ensuring long-term preservation of the study data. Through the data curation process, data are cleaned and standardized for use, and data documentation is rigorously developed so that data sets and the associated documentation can be understood at a basic by any potential users. The uploaded data will be de-identified to ensure no linkages to individual research participants and will exclude variables that could lead to deductive disclosure of the identity of any individual subjects.
