In the mid-1970’s, Saad Nagi was the principal investigator of a study pertaining to child maltreatment in the United States. A nationwide sample of organizations that deal with child maltreatment issues was asked to participate. Types of organizations involved included hospitals, child protective services, law enforcement agencies, schools and courts. Specific personnel in each type of organization were asked to respond to questions about the nature and scope of the issues they faced in attempting to address the aspects of child maltreatment with which they dealt. Additionally they were asked to comment on the resources at their disposal and problems that they faced in carrying out their jobs.
