Using multiple data time points this study investigated the prospective validity of a secondary gang prevention program called Gang Risk of Entry Factors (GREF) assessment. At Time 1 of the study interview cut-points were established for high and low risk on nine risk factors that were included on the assessment. Those who scored high risk on four or more risk factors were determined eligible for secondary prevention. At time 2 each participate was then classified into one of four levels of gang membership. The goal of this was to investigate how successful the GREF was in identifying the youth (in the absence of a program) who become associated with a street gang in the 12 to 18 months of the study time frame .
