The role of friends, in-laws, and other kin in father-perpetrated child physical abuse.

Thirty-five physically abusive fathers were matched with a comparison sample to test multiple systemic explanations for child physical abuse, using an ecological perspective, and to show the relationship between the structure of social ties and the function of those ties. The physically abusive fathers were found to have received significantly fewer emotional and instrumental supports from their friends, in-laws, and other kin than the comparison fathers, and were only weakly linked to members of their social networks--members who might have discouraged the fathers' aggressive impulses or provided additional support to them and to their families.
