In their study, they used a sample of delinquent youth, both white and non-white, to examine negative strains experienced by youth that could have led to crime. The results they found were surprising. Unlike Agnew's claim that African Americans would experience greater strain conducive to crime and have fewer resources to cope with it due to their disadvantages, in reality it was just the opposite. Whites were the ones who experienced more tension towards anger and aggression. But, coincidentally, non-White youth have had more prior arrests than White youth (Piquero & Sealock, 2010). The next thing they discovered was that both Whites and non-Whites showed positive and significant signs of the effects of tension and anger, meaning that young people who experienced more tension also experienced high levels of anger (Piquero and Sealock, 2010) . But they found that stress led more nonwhites than whites to depression (Piquero & Sealock, 2010). They stated that the GST appears to help explain the understanding of events leading to criminal involvement, regardless of the group examined (non-whites and whites), but also the need to take into account apparent differences between groups (Piquero and Sealock et al., 2010:
