The objective of this article is to describe abuse and neglect of adults age 65 and older in Michigan nursing homes, as reported by members of their families. Using list-assisted random-digit dialing, data on abuse and neglect for a 12-month period were collected from individuals who had a relative age 65 or older in a Michigan nursing home. Of the nursing home residents represented in this analysis, the majority were female, Caucasian, and widowed. Neglect and caretaking mistreatment were the most frequent types of abuse reported. Comparison of these data with data from the National Ombudsman Reporting System suggests that family members constitute a sensitive source of data on abuse in nursing homes.
