The study was done to develop a shared decision-making scale for end-of-life patients in Korea.
The process included construction of a conceptual framework, generation of initial items, verification of content validity, selection of secondary items, preliminary study, and extraction of final items. The participants were 388 adults who lived in one of 3 Korean metropolitan cities: Seoul, Daegu, or Busan. Item analysis, factor analysis, criterion related validity, and internal consistency were used to analyze the data. Data collection was done from July to October 2011.
Thirty-four items were selected for the final scale, and categorized into 7 factors explaining 61.9% of the total variance. The factors were labeled as sharing information (9 items), constructing system (7 items), explanation as a duty (5 items), autonomy (4 items), capturing time (3 items), participation of family (3 items), and human respect (3 items). The scores for the scale were significantly correlated among shared decision-making scale, terminating life support scale, and dignified dying scale. Cronbach's alpha coefficient for the 34 items was .94.
The above findings indicate that the shared decision-making scale has a good validity and reliability when used for end-of-life patients in Korea.
本研究旨在开发一种适用于韩国临终患者的共同决策量表。
该过程包括构建概念框架、生成初始项目、验证内容效度、选择二级项目、初步研究以及提取最终项目。参与者为居住在韩国三个大城市（首尔、大邱或釜山）之一的388名成年人。采用项目分析、因子分析、效标关联效度和内部一致性分析数据。数据收集于2011年7月至10月进行。
最终量表选取了34个项目，分为7个因子，解释了总方差的61.9%。这些因子分别被标记为信息共享（9项）、系统构建（7项）、解释职责（5项）、自主性（4项）、把握时机（3项）、家庭参与（3项）和尊重人性（3项）。该量表得分与共同决策量表、终止生命支持量表和尊严死亡量表之间存在显著相关性。34个项目的克朗巴赫α系数为0.94。
上述研究结果表明，该共同决策量表用于韩国临终患者时具有良好的效度和信度。
