abstract
Among the behavioral disturbances associated with dementia, wandering and wandering-related activities are perhaps the most difficult for family caregivers and care staffs. However, because the causes and the patterns of wandering are not identical in all patients, and are rather influenced by the individual backgrounds, there is not much quantitative research of the wandering behavior itself. The purpose of this paper is to demonstrate, through a single case study of an elderly person with dementia, quantitative patterns of wandering behavior so that these behavior analysis methods can be incorporated into nursing home care. This research was conducted in a nursing home, Furusato-no-Ie “Joka", in Shimabara, Nagasaki Prefecture. The subject of this current study was one elderly woman, 79 years old, with mild dementia (35 points on the NM scale; 48 points on the N-ADL). For a one week research period, a blotter was set at the entrance of the nursing home and the exact time of the subject's entry and exit were recorded. Three one-day periods before and after the wandering research period, the behavior in daily life of the subject was video taped 6 times a day (10 minutes per time). The video data, processed point- and one-zero-sampling methods, showed interpersonal behaviors and facial expressions of the subject. The subject comes and goes very frequently at the vestibule to the home from before dawn to dusk every day. A total of 232 outings were observed in the research period, of which 211 were free-will outings. The subject's outing period accounts for about 460f potential time, so the outing was regarded as having become an inextricable part of life for the subject. Of all the parts and places in and out of the nursing home, the entrance seems to play the essential role in promoting the residents' and staffs' mutual interactions. The subject's communication behavior and positive emotional expressions such as laughter and smiling were notably observed around
