Abstract

Background To better assess the outcomes of advance care planning (ACP) as an ongoing process, it is necessary to use a validated and reliable measure reflecting the full range of processes involved in ACP. Thus, we examined the psychometric properties of the Korean version of the ACP Planning Engagement Survey developed by Sudore and colleagues.

Methods We selected 22 items from an original 85-item instrument, which was made based on the relevant Korean law and was to avoid the redundancy of action items. The ACP Engagement Survey was translated into Korean, back-translated, and culturally adapted, and a psychometric evaluation of the final version was conducted. Pearson’s Correlation coefficient between the ACP Engagement Survey score and knowledge score of advance directive was analyzed to assess their relationship. Factor analysis was conducted to identify the structure of the Korean version of the ACP Engagement Survey. for assessing internal consistency, Cronbach’s alpha was calculated.

Results A total of 235 older adults (mean age of 71.1) were included in the analysis. The criterion validity of the Korean version of the ACP Engagement Survey was supported by a significant correlation with the knowledge score of advance directives (r = 0.26, p < .001). The total number of items was reduced to 12 and the factor structure of the 12-item model was the same 3-factor structure as the original version (readiness, contemplation, and self-efficacy). The final Korean version of the ACP Engagement Survey showed acceptable Cronbach’s alphas (α = .93). for each domain, the α values were .93 for readiness, .85 for contemplation, and .87 for self-efficacy.

Conclusion Findings provided preliminary evidence of the reliability and validity of the Korean version of the ACP Engagement Survey in older adults. Nonetheless, further evaluation, including item relevance and rest-retest reliability, is warranted.
