The Knowing-Doing Gap in Advance Directives in Asian Americans: The Role of Education and Acculturation.

OBJECTIVES: The purposes of the present study were (1) to explore the completion rate of advance directives (ADs) in a sample of Asian Americans and (2) to examine the direct and moderating effects of knowledge of AD, education, and acculturation in predicting AD completion. Education and acculturation were conceptualized as moderators in the link between knowledge and completion of ADs.

METHODS: Using data from 2609 participants in the 2015 Asian American Quality of Life survey (aged 18-98), logistic regression analyses on AD completion were conducted, testing both direct and moderating effects.

RESULTS: The overall AD completion rate in sample was about 12%. The AD knowledge and acculturation independently predicted AD completion. No direct effect of education was found; however, it interacted with AD knowledge. The AD knowledge was more likely to be translated into completion in the group with higher education.

CONCLUSIONS: The AD completion rate observed in the present sample of Asian Americans was much lower than that of the US general population (26%-36%). The interactive role of education helps to explain the gap between AD knowledge and completion and suggests intervention strategies.
