Abstract
Context
Self-efficacy and readiness for advance care planning (ACP) is underresearched in
the Chinese population given that these are novel concepts in the culture.
Objectives
To translate the self-efficacy and readiness subscales of the ACP Engagement Scale
into Chinese using the Brislin's Model and test its psychometric properties in Chinese
older adults.
Methods
Content validity and face validity were established based on the views of a group
of experts and older adults. Then, a survey was conducted with a convenience sample
of 204 community-dwelling older adults. Convergent validity was evaluated using Pearson's
correlation coefficients with the SURE test, a decisional conflict scale. The scores
between older adults who had hospitalization experience in the previous year and those
who did not have were compared to examine discriminant validity.
Results
The findings showed that the Chinese subscales had good internal consistency (Cronbach's
α 0.94–0.97) and acceptable one-week test-retest reliability (intraclass correlation
coefficient 0.66–0.70). There was a significantly high correlation between the self-efficacy
and the readiness subscales (r = 0.809; P < 0.01) and moderate correlation between the two subscales and the SURE test (r = 0.509–0.587; P < 0.01). Discriminant validity was supported by significant differences between older
adults who had hospitalization experience in the last year and those who did not have
(P < 0.05).
Conclusion
The Chinese readiness and self-efficacy subscales of the ACP Engagement Survey are
valid and reliable tools for assessing the preparedness of the Chinese older adults
for ACP.
