This theory is similar to ecological theory in that both focus on the entire family unit when assessing the needs and service approach for responding to child abuse and neglect. Family systems theory, however, focuses primarily on the family and is a process of identifying problems as the consequences of dysfunctional relationships among family members. For example, in cases of incest where the father is the perpetrator, the possibility that the mother’s reluctant intervention may appear to be tacit approval would be explored as a contributing factor in the repeated abuse. Critics are concerned with this theory’s failure to recognize the influence of power and society on human behavior. Some critics worry that the discussion of the victim’s and bystander’s roles in the abuse may be overemphasized and relieve the perpetrator of responsibility.
