Unfolding and displaying the influencing factors of advance directives from the stakeholder's perspective: A concept mapping approach.

Abstract

To develop a culturally relevant conceptual map to discover perceptions of a statutory form of advance directive (AD) for Hong Kong Chinese. This was the first study on AD using a concept mapping approach with two phases. The data collection of the two phases was conducted from February 2016-February 2017. In Phase I, 96 participants were recruited using purposive sampling. In Phase II, multi-dimensional scaling and hierarchical cluster analysis were used to create a concept map based on quantitative data. The map depicted six clusters of factors affecting the acceptance of AD, with their importance rating in decreasing order: Conditional factor, value system, process of AD, physical and illness factor, personal situation factor, and socio-cultural factor. The study adopted a comprehensive approach to unfolding the multi-faceted factors affecting the acceptance of ADs by stakeholders. Strategies targeting the clusters could be developed to facilitate the discussion and completion of AD.
