Content validity was assessed through expert evaluations by five experts and cognitive interviews with five participants diagnosed with chronic diseases, and internal consistency reliability, construct validity, and criterion validity were assessed through an online survey. A total of 340 adults with chronic diseases were recruited through a panel research service, with 170 assigned to each group for exploratory factor analysis (EFA) and confirmatory factor analysis (CFA).

RESULTS

The Korean version of the Advance Care Planning Engagement Survey comprises 34 items and demonstrated good internal consistency (.78-.96). The EFA identified four behavioral factors-Knowledge, Contemplation, Self-efficacy, and Readiness-accounting for 64.4% of the cumulative variance. The CFA results indicated a good model fit.

CONCLUSION

The Korean version of the Advance Care Planning Engagement Survey demonstrated validity and reliability in assessing advance care planning engagement within the Korean context. By reflecting cultural nuances, this instrument supports cross-cultural comparisons and contributes to evidence-based end-of-life care policies. It also aligns with global healthcare needs, facilitating culturally informed research and enhancing patient-centered care. Additionally, it aids in the development of advance care planning programs that consider cultural contexts, supporting more effective end-of-life care in diverse settings.
