目的：研究人员和临床医生认识到计划未来失能事件所需的医疗治疗的复杂性。不幸的是，由于缺乏可以证明有效性的措施，许多评估这种困难规划质量的尝试都受到阻碍。本研究探讨了决策冲突量表（DCS）作为衡量患者对其临终决策过程的评价时的心理测量学特征。这项评估使用了来自两个独立样本的合并数据，其中59名患有危及生命的疾病的门诊患者及其代理决策者被分配接受决策辅助干预，以病人为中心的预先护理计划（PcACP），或通常careonly.Results：内部一致性的DCS在临终决策的背景下是很高的。DCS表现出收敛性，结构，判别效度的基础上的总规模scores.Conclusion：DCS似乎是一个可行的研究工具，用于测量的质量结束了生命的决策。然而，不确定性分量表表现出较弱的辨别能力和缺乏关联的其他两个分量表，修改的因素，有助于不确定性和有效性的决策making.Practice的影响：该研究的结果可以是有用的，用于测量个人的决策冲突与严重疾病面临着结束生命的决策。(c)2005爱思唯尔爱尔兰有限公司保留所有权利。
Objective: Researchers and clinicians acknowledge the complexity of planning for future medical treatment desired in the event of incapacitation. Unfortunately, many attempts to evaluate the quality of such difficult planning have been stymied by the lack of measures that can be shown to have validity. This study examines the psychometric characteristics of the Decisional Conflict Scale (DCS) when used as a measure of patients' evaluation of their end-of-life decision-making process.Methods: This evaluation used the combined data from two independent samples in which 59 outpatients with a life-threatening illness and their surrogate decision makers were assigned to receive, a decision aid intervention, the patient-centered advance care planning (PcACP), or usual care only.Results: Internal consistency for the DCS in the end-of-life decision-making context was high. The DCS demonstrated convergent, construct, and discriminant validity based on the total scale scores.Conclusion: The DCS appears to be a viable research instrument for measuring the quality of end-of-life decision making. However, the uncertainty subscale showed a weak discriminating ability and lack of association with the two other subscales, the modifiable factors contributing to uncertainty and the effectiveness of the decision making.Practice implications: The findings of the study can be useful for measuring decisional conflict in individuals with serious illness facing end-of-life decision making.
