This article describes a survey of 84 adults with disabilities who received personal assistance with activities of daily living from family members, informal providers, or agency personnel. Results showed that 30 percent reported mistreatment from their primary provider, and 61 percent reported mistreatment by another provider. Verbal abuse, physical abuse, and theft or extortion were the most common forms of mistreatment by primary providers. Verbal abuse, neglect, poor care, and theft were the most common forms of mistreatment by other providers. Adults with lower incomes were the most likely to experience mistreatment. Male providers were more likely to mistreat, as were providers who were inexperienced and who provided more than 50 hours of care per week.
