abstract="Research Summary:  This manuscript presents results from the National Evaluation of the Gang Resistance Education and Training (G.R.E.A.T.) program, a school-based prevention program targeting middle-school students. A longitudinal quasi-experimental research design was conducted from 1995 through 1999. Beneficial program effects emerged gradually over time so that there was, on average, more pro-social change in the attitudes of G.R.E.A.T. students than the non-G.R.E.A.T. students four years following program exposure.<p />",
