Risk of behavior problems among nursing home residents in the United States.

This study identified personal risk factors associated with behavior problems among nursing home residents using data based on a national survey of nursing home residents. Data are based on the Institutional Population Component of the 1987 National Medical Expenditure Survey and include nursing home residents living in licensed facilities on January 1, 1987. Multiple regression analyses were conducted to examine characteristics of residents that place them at risk of behavior problems. Independent variables include physical functioning, sensory impairment, cognitive impairment, psychiatric diagnoses, and demographics. Eleven behavior problems grouped into four categories based on factor analysis serve as dependent variables: wandering/safety, aggressive behaviors, collecting behaviors, and delusions/hallucinations. Risk factors emerging as predictors included sex (male), cognitive impairment, ADL dependency, incontinence, psychiatric history, receptive communication, walking, and difficulty seeing. Risk factors differ by type of behavior problem. Results suggest a multiple etiology in which biological, psychological, and sociocultural factors all play a role in generating behavior problems in the long-term care setting.
