The purpose of this study was to examine the psychometric properties of the Advance Directive Attitude Survey in Korean (K-ADAS), a measure of attitudes toward advance directives (ADs). A total of 118 low-income, community-dwelling older adults (mean age, 75.09 years) participated. An exploratory factor analysis (EFA) was conducted to determine the factor structure of the K-ADAS. Validity was further assessed by known associations of the K-ADAS with perceived susceptibility and severity using part of the Advance Care Planning surveys. Its reliability was examined by calculating alpha coefficients. EFA determined a three-factor structure model with good model fit. Validity was further supported with significant correlations between the K-ADAS and susceptibility and severity. Reliability was supported by adequate level of Cronbach's alpha. The K-ADAS was a valid and reliable measure for assessment of AD attitudes with a sound model fit. Thus, the K-ADAS can be used to assess AD attitudes among community-dwelling elders.
本研究旨在检验韩国版预先医疗指示态度调查（K-ADAS）的心理测量特性，该调查用于衡量对预先医疗指示（AD）的态度。共有118名低收入、居住在社区的老年人（平均年龄75.09岁）参与。进行了探索性因素分析（EFA）以确定K-ADAS的因素结构。使用部分预先护理计划调查，通过K-ADAS与感知易感性和严重性的已知关联进一步评估效度。通过计算阿尔法系数来检验其信度。EFA确定了一个模型拟合良好的三因素结构模型。K-ADAS与易感性和严重性之间的显著相关性进一步支持了效度。克朗巴赫阿尔法系数的适当水平支持了信度。K-ADAS是一种评估AD态度的有效且可靠的测量工具，模型拟合良好。因此，K-ADAS可用于评估居住在社区的老年人对AD的态度。
