Keeping wandering nursing home residents at the table: improving food intake using a behavioral communication intervention.

The purpose of this multiple case design study (n = 3) with an embedded experiment was to determine the effect of the systematic use of a behavioral nursing intervention on the mealtime behavior of nursing home residents with probable Alzheimer's disease. It was hypothesized that the systematic behavioral intervention would increase time spent seated during the meal and proportion of food consumed while decreasing the frequency of table-leaving events during mealtime. The intervention was designed to impact the proximal factors of physiological need and social interaction from the Need-Driven Behavior Model. Results demonstrate that all cases were able to sit at the table longer and eat more food during the intervention, while body weight for all cases remained stable throughout the study. Two of the three cases left the table fewer times during the intervention. There were no statistically significant changes in proportion of fluids consumed in any case.
