The effects of language used by caregivers on agitation in residents with dementia.

In this study, We addressed the problem of whether residents with a diagnosis of dementia would become agitated if given verbal commands at a level of language complexity above their comprehension ability. The study used an A-B-A research design. The convenience sample of 15 subjects was comprised of 11 men and 4 women who resided in a long-term care institution. Their mean age was 86.6 years, and their average length of stay in the institution was 317.3 days. The results lent support to the hypothesis that exposing residents with dementia to language beyond their comprehension ability could result in agitated behavior. The predominant manifestations of agitation were general restlessness, strange noises, and negativism. An important implication for nursing practice is that the language used by caregivers should match the comprehension ability of residents. Caregiving can thereby facilitate communication and, potentially, prevent agitation.
