Research has seldom examined how identity mechanisms facilitate violence among gang members. Relying on life history interviews with self-identified former gang members, we use identity theory to explore the relationship between commitment to the gang identity and violence. Results indicate that the relationship between commitment and violence is complex. Specifically, for individuals with a high degree of cognitive commitment to the gang identity, violence will be used to achieve positive and confirming reflected appraisals. However, once gang members have achieved congruence between reflected appraisals and identity standards, a threshold is reached where violence is no longer required.
