Brief Summary

The goal of this study is to help build the evidence base for a locally-relevant youth firearm violence prevention program in Washington D.C., a city experiencing disparities in youth firearm violence outcomes. The main question it aims to answer is: How is youth participation in the summer youth employment program, the True Reasons I Grabbed the Gun Evolved from Risk (The T.R.I.G.G.E.R Project), which is designed to address root causes of gun violence, associated with individual youth behavioral outcomes, including pro-social involvement, aggression, and firearm-related attitudes and behaviors?

Outcome Measures

Primary Outcomes (7)

  • Change in Civic Efficacy

    The investigators will assess change in civic efficacy (i.e., youth participants' sense of belief that they can create positive change in their communities) over time using the 3-item Civic Efficacy scale; the unit(s) of measurement are the Mean and Standard Deviation of scale scores; Minimum Value: 1 Maximum Value: 5, higher scores indicate a better outcome

    Outcomes will be measured at 4 time points over 1 year: at the start of the summer programs, 2-4 weeks post, 6-months post, and 1-year post participation

  • Change in Pro-Social Involvement

    The investigators will assess change in pro-social involvement (i.e., youth participants' involvement in pro-social community organizations and activities) over time using an 8-item adapted Participation in Groups and Voluntary Organizations scale; the units of measurement are the Mean and Standard Deviation of scale scores; Minimum Value: 0 Maximum Value: 8; higher scores indicate a better outcome

    Outcomes will be measured at 4 time points over 1 year: at the start of the summer programs, 2-4 weeks post, 6-months post, and 1-year post participation

  • Change in Attitudes towards Violence and Retaliation

    The investigators will assess change in youth participants' attitudes toward violence and retaliation over time using a 3-item Retaliatory Attitudes scale; the units of measurement are the Mean and Standard Deviation of scale scores; Minimum Value: 1 Maximum Value: 5; lower scores indicate a better outcome

    Outcomes will be measured at 4 time points over 1 year: at the start of the summer programs, 2-4 weeks post, 6-months post, and 1-year post participation

  • Change in Aggressive Behavior

    The investigators will assess change in non-firearm related aggressive behavior (i.e., fighting, non-firearm weapon carriage) over time using a 3-item Aggressive Behaviors scale; the unit(s) of measurement are the Mean and Standard Deviation of scale scores; Minimum: 0, Maximum: 15, lower scores indicate a better outcome

    Outcomes will be measured at 4 time points over 1 year: at the start of the summer programs, 2-4 weeks post, 6-months post, and 1-year post participation

  • Change in Firearm Carriage Frequency

    The investigators will assess change in the frequency of firearm carriage (for any reason besides hunting, target shooting, competitive shooting, or recreation) over time using 1-item; the unit(s) of measurement are the Mean and Standard Deviation of scale scores; Minimum: 1 Maximum: 7, lower scores indicate a better outcome

    Outcomes will be measured at 4 time points over 1 year: at the start of the summer programs, 2-4 weeks post, 6-months post, and 1-year post participation

  • Change in Firearm Use

    The investigators will assess change in youth participants' firearm use (i.e., handling a gun, firing a gun, holding a gun in a selfie) over time, using a three-item Firearm Use scale; the unit(s) of measurement are the Means and Standard Deviations of scale scores, Minimum: 0 Maximum: 18, lower scores indicate a better outcome

    Outcomes will be measured at 4 time points over 1 year: at the start of the summer programs, 2-4 weeks post, 6-months post, and 1-year post participation

  • Change in Firearm Aggression

    The investigators will assess change in youth participants' firearm aggression (i.e., threatening someone with a gun, firing at or around someone), using a two-item scale adapted from the Revised Conflict Tactics Scale; the unit(s) of measurement are the Means and Standard Deviations of scale scores, Minimum: 0 Maximum: 10, lower scores indicate a better outcome

    Outcomes will be measured at 4 time points over 1 year: at the start of the summer programs, 2-4 weeks post, 6-months post, and 1-year post participation

Data Sharing

IPD Sharing
Will share

The investigators will archive the data collected for this study in the Institute for Firearm Injury Prevention (IFIP) Data Repository so that the data will be connected to a national data resource on firearm injury prevention research. The IFIP repository is housed online at the Inter-University Consortium for Social and Political Research (ICPSR) (https://www.openicpsr.org/openicpsr/facts-open). All data uploaded to the repository will be de-identified, such that all sensitive, identifiable, or potentially identifiable information will be removed from the dataset. At a minimum, each data deposit in the archive will include the data set(s), codebook, data collection instrument, and a summary of the project.

Shared Documents
STUDY PROTOCOL
Time Frame
All final data collected during the course of this research will be disseminated in a timely manner and as completely and accurately as possible, in accordance with Centers for Disease Control policy. The investigators will make the final version of the collected public health datasets available in a non-proprietary format within 30 months after the end of data collection in September 2026 via the Institute for Firearm Injury Prevention (IFIP) Data Repository portal. All identifiers will be removed from the data prior to dissemination. In compliance with the 1996 Health Insurance Portability and Accountability Act (HIPPA) wherever applicable. The data will be provided in standard file formats accompanied by the necessary documentation to allow for independent analyses. Once deposited, the de-identified data will be publicly available indefinitely.
