The study was conducted in two Indiana counties, one with a population of 350,000 and the other with a population of 75,000. Of 150 questionnaires mailed to police officers, 51 were completed (34 percent response rate). Of 100 questionnaires mailed to social service providers, 55 were returned (55 percent response rate). Seventeen police officers reported 112 cases of abuse or neglect, while 34 reported none. Of the 55 visiting nurses and social service personnel reporting, 38 encountered 146 elder abuse cases, 15 sexual abuse cases, and 422 neglect cases. Police officers viewed family conflict as the primary factor in elder abuse and neglect cases. They viewed the role of police protection as having the greatest potential for reducing elder abuse and neglect. Visiting nurses and social service personnel saw the role of personal services as important in reducing elder abuse and neglect. It is concluded that the effectiveness of elder abuse and neglect services requires cooperation between police officers and social service providers. 16 references, 5 tables.
