Wandering behaviour of persons with dementia in Korea: Investigation of related factors

초록

Objectives: Despite being identified as a significant clinical phenomenon, wandering of persons with dementia (PWDs) has not been studied in Korea. As an initial trial, various factors chosen from the literature for their predictive relationships to wandering of Korean PWDs were evaluated in this study. Method: A total of 160 PWDs residing in 14 long-term care facilities participated in this study. The Mini-Mental State Exam (MMSE), Physical Activities of Daily Living (PADL) and Korean-translated Revised Algase Wandering Scale (Nursing Home version) (KRAWS-NH) were used to assess participants' degree of cognitive impairment, functional ability and wandering behaviour on six dimensions: persistent walking (PW), specific patterns (SP), spatial disorientation (SD), escape behaviour (EB), attention shift (AS) and negative outcomes (NO). Demographic, personal and environmental data were also collected. Results: The MMSE score was a significant negative predictor for KRAWS-NH overall and subscales except for EB; while age, PADL and history of falls were positive predictors for SD and NO. Total number of residents in a room was a significant negative predictor for EB and AS. Conclusion: Different factors found in PWDs may contribute to different aspects of wandering behaviour. Further studies on factors influencing multiple facets of wandering in various cultural settings are warranted.
