Understanding The T.R.I.G.G.E.R Project for Gun Violence Prevention

This study, called "Addressing Root Causes for Gun Violence Prevention (ARC-GVP)," is looking at how a program called The T.R.I.G.G.E.R Project helps young people. The T.R.I.G.G.E.R Project is a behavioral program that includes summer jobs, social and emotional learning, and adult support to address the reasons behind gun violence. Researchers want to see if participating in this program changes how young people act, their involvement in positive activities, and their attitudes about violence. You can join if you are between 14 and 24 years old and are already part of The T.R.I.G.G.E.R Project in Washington D.C. The study aims to enroll 250 participants and is currently observing participants, not testing a new treatment.

Study design
This is an observational study, meaning researchers will watch and collect information from 250 participants who are already part of The T.R.I.G.G.E.R Project.
What's involved
Participants will complete four surveys over one year: at the start of the program, 2-4 weeks after it ends, 6 months after, and 1 year after.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for one year after starting the program, with surveys at 2-4 weeks, 6 months, and 1 year post-program.

Eligibility criteria

Inclusion

Youth in Washington D.C. who are participating in The T.R.I.G.G.E.R Project, a grassroots youth firearm violence prevention program

Exclusion

Emancipated minors
  • Change in Civic EfficacyOutcomes 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

    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

  • Change in Pro-Social InvolvementOutcomes 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

    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

  • Change in Attitudes towards Violence and RetaliationOutcomes 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

    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

  • Change in Aggressive BehaviorOutcomes 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

    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

  • Change in Firearm Carriage FrequencyOutcomes 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

    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

  • Change in Firearm UseOutcomes 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

    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

  • Change in Firearm AggressionOutcomes 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

    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
