To evaluate the psychometric properties of the Korean version of the Way-finding Effectiveness Scale (WES) for Korean persons with dementia (PWDs).
A descriptive, cross-sectional survey method was used.
Data were collected with a non-probability sampling strategy using structured format face-to-face interviews. A convenience sample of 83 community-dwelling PWDs and their family caregivers were recruited. The participants were PWDs who were over 60 years of age, had been medically diagnosed with dementia or showed signs and symptoms of dementia, had a Mini Mental State Examination (MMSE) score of less than 24 of 30 and were independent in walking.
Internal consistency for the 29-item KWES was 0.93 and exceeded 0.70 for the four subscales (complex way-finding goals, CWG; analytic strategy, AS; global strategy, GS; and simple way-finding goals, SWG). The intercorrelations for total KWES and subscales demonstrated a high to moderate relationship ranging from 0.84 (total and CWG) to 0.24 (AS and SWG). Pearson correlations between each subscale scores of the KWES and K-MMSE demonstrated significant, moderate relationships ranging from 0.41 (CWG and K-MSE) to 0.28 (AS and K-MMSE). Differences in current and prior behaviour of KWES were significant for the total (t = -21.00, p < 0.001) and subscales (t = -28.33--9.33, p < 0.001).
Acceptable reliabilities and validities support the conclusion that the KWES is a valid and reliable instrument for examining way-finding effectiveness for Korean PWDs.
The KWES will contribute to the development of understanding of way-finding ability for community-dwelling PWDs in both research and clinical practices.
评估韩国版寻路效能量表（WES）在韩国痴呆症患者（PWDs）中的心理测量特性。
采用描述性横断面调查方法。
使用结构化格式的面对面访谈，通过非概率抽样策略收集数据。招募了83名社区居住的痴呆症患者及其家庭照顾者作为便利样本。参与者为60岁以上、经医学诊断患有痴呆症或有痴呆症体征和症状、简易精神状态检查表（MMSE）得分在30分制中低于24分且行走独立的痴呆症患者。
29项韩国版寻路效能量表（KWES）的内部一致性为0.93，四个子量表（复杂寻路目标，CWG；分析策略，AS；全局策略，GS；简单寻路目标，SWG）均超过0.70。KWES总量表与子量表之间的相互关系显示出高到中等的相关性，范围从0.84（总量表与CWG）到0.24（AS与SWG）。KWES各子量表得分与韩国版简易精神状态检查表（K-MMSE）之间的皮尔逊相关性显示出显著显著显著显著的中等关系，范围从0.41（CWG与K-MMSE）到0.28（AS与K-MMSE）。KWES当前与先前行为的差异在总量表（t = -21.00，p < 0.001）和子量表（t = -28.33--9.33，p < 0.001）中均具有显著性。
可接受的信度和效度支持以下结论：KWES是用于检验韩国痴呆症患者寻路效能的有效且可靠的工具。
KWES将有助于在研究和临床实践中加深对社区居住痴呆症患者寻路能力的理解。
