The purpose of this study was to examine the psychometric properties of a Korean translated version of the Revised Algase Wandering Scale, community version (K-RAWS-CV) among persons with dementia in Korea. A cross-sectional survey design was used. After established equivalence of the instrument using back-translation and a field test, 69 community dwelling family caregivers described the wandering behaviour of their family members with dementia. The overall mean of the K-RAWS-CV was 1.73 (SD?=?0.61, range?=?1–3.87). Means of each subscale ranged from 1.44 (meal-time impulsivity, MI) to 2.04 (escape behavior, EB). The reliability alpha for the overall scale was 0.96 with reliabilities for subscales ranging from 0.82 (negative outcome, NO) to 0.93 (persistent walking, PW). The correlation between the overall K-RAWS-CV and each subscale ranged from 0.52 (overall and NO) to 0.82 (overall and PW) with a mean value of 0.66. Pearson's correlations between the level of cognitive impairment and each subscale of the K-RAWS-CV demonstrated significant, moderate relationships ranging from -0.24 (MI, RW, and MMSE) to -0.39 (PW, EB and MMSE). Mean differences between wanderers and non-wanderers were statistically significant for the K-RAWS-CV overall and all subscale except for MI. Results support the validity and reliability of the K-RAWS-CV overall and the six subscales.

The aim was to analyze the factor structure, the criterion validity, the internal consistency, inter-rater reliability and test-retest reliability of the Korean version of Cohen-Mansfield Agitation Inventory, to provide data on the frequency and distribution of agitated behaviours, and to compare patterns of agitated behaviours among the institutionalized elderly with Alzheimer's disease (AD) or Vascular dementia (VaD). The Korean version of the Cohen-Mansfield Agitation Inventory (CMAI-K) was administered to a total of 257 elderly with AD or VaD in a nursing home in Seoul, Korea. Three kinds of reliability and criterion validity were tested. Factor analysis using principal component analysis with the varimax rotation was performed. To identify different patterns of agitated behaviours, multiple logistic regression analysis was used. This study demonstrated satisfactory reliability and validity for the CMAI-K as an instrument measuring agitation in Korean dementia sufferers in nursing homes. Eighty-three percent of the subjects manifested one or more agitated behaviours at least once a week. Factor analysis yielded four subtypes of agitation: physically aggressive behaviours, physically nonaggressive behaviours, verbally agitated behaviours, and hiding/hoarding behaviours. These results indicate that the CMAI-K is a reliable and valid instrument to measure agitated behaviours in Korean elderly with AD or VaD. These results validate and expand previous research on the agitation in dementia, and guide in the development of interventions.
