Abstract
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.
Highlights
Longer lives with multiple chronic conditions are becoming increasingly burdensome to elderly people, as well as current society [1,2,3,4]
One hundred and eighteen older adults who had chronic illnesses residing in community settings participated in this study
Considering the supported validity and reliability of the modified K-Advance Directives Attitude Survey (ADAS) in this study, our findings initially provide insights into the advance directives (ADs) attitudes in chronically ill people in the community
Summary
Longer lives with multiple chronic conditions are becoming increasingly burdensome to elderly people, as well as current society [1,2,3,4]. According to a recent report, most older Koreans aged 65 years or older (88.5%) had one or more chronic health conditions with an average of 2.5 multi-morbidities [6]. The prevalence of such major chronic diseases in Korean adults is projected to increase approximately. Living with multi-morbidities often involves considerable physical, psychological, and financial impact from associated emergency department visits or hospitalizations for treatment, therapeutic procedures, and unexpected adversities or avoidable high mortality [4,12]. These chronically ill people and/or their families who may or may not have life-limiting conditions are often exposed to a spectrum
