"During the past quarter century adolescent street gangs, once primarily a phenomenon of a few major metropolitan areas, have spread rapidly throughout the United States. In its most recent survey, the National Youth Gang Center estimated that there were 30,700 gangs with 850,000 members located in over 3,100 jurisdictions throughout the country. Gangs were found in 85% of larger cities, 50% of suburban counties, 32% of smaller cities, and 15% of rural counties. The number of gangs, gang members, and gang-related homicides are on the rise when compared to the previous 5-year average and the problem of street gangs now reaches into all corners of American society (Egley, et al., 2014). [...] The purpose of this study was to produce knowledge about how to prevent at-risk youth from joining gangs and reduce delinquency among active gang members. The study evaluated a modification of Functional Family Therapy, a model program from the Blueprints for Healthy Youth Development initiative, to assess its effectiveness for reducing gang membership and delinquency in a gang-involved population."
