Discussion
Substantial evidence supports the effectiveness of anger and aggression interventions. However, there are several limitations to this literature. First, most of the research presented in this review, with the exception of one metaanalysis [4], included group therapy and not anger management classes. The term class implies larger numbers of participants per intervention or session than for group or individual therapy. Also, anger management classes are largely psychoeducational in nature and treatment is not based on an individualized case conceptualization. It is a serious problem that we have little empirical data on the effectiveness of this particular intervention while it continues to be commonly mandated.
Second, no meta-analysis has examined the effectiveness of anger or aggression treatments for domestic violence or child abuse perpetrators, and only one meta-analysis in the current review included abusive parents and spouses in their overall sample [15]. There is a serious lack of progress in this important area of service delivery [24] given the multi-level consequences of domestic violence, and represents a critical area for future treatment research of anger and aggression.
