G.R.E.A.T. Follow-up Study

The G.R.E.A.T. Follow-up Study is designed to test the long-term effectiveness of the Gang Resistance Education and Training (G.R.E.A.T.) Program.

The G.R.E.A.T. Program was established in the 1990s as a proactive response to combating youth violence and gang activity. The program was designed to engage 6th and 7th graders through school-based curriculum taught by local law enforcement officers.

The team of researchers conducting this follow-up study are working with nearly 4,000 adults who participated in the G.R.E.A.T. evaluation as children between 2006 and 2011 while living in various urban environments across the United States. This includes cities such as Albuquerque, NM; Chicago, IL; Greeley, CO; Nashville, TN; Philadelphia, PA; Portland, OR; and a suburb of Dallas/Fort Worth TX.


The objective of the G.R.E.A.T. Follow-up Study is threefold.

  1. Identify any long-lasting effects of the program on such things as gang membership and attitudes towards law enforcement.
  2. To examine the impact of positive and negative life events on the transition to adulthood.
  3. To understand whether experiences in adolescence have lasting effects into adulthood.
