摘要：

目的：探讨在医疗情境中，年轻人和老年人为不同角色决策时的差异。方法：采用2（年龄：年轻人、老年人）×3（生命质量权重：高、中、低）×3（决策角色：陌生人、亲人、自我）的混合实验设计。因变量为被试对两个质量调整生命年基本相等，但生命质量权重和生命长度不同的方案的选择倾向性。结果：与生命质量高长度短的选项相比，老年人比年轻人更倾向于选择生命质量低但长度长的选项；无论是年轻人还是老年人，为自己决策时更倾向于选择生命质量高长度短的选项，而为亲人和为陌生他人决策时都倾向于选择生命质量低但长度长的选项。结论：在医疗决策过程中决策者会权衡生命质量与生命长度，为自己和为他人决策时分别赋予生命质量和生命长度不同的价值。

Objective: To explore the discrepancies of age and self-other decision making in medical situation. Methods: A 2×3×3 experiment was designed. 117 youths and 85 old people took part in this study and finished a medical decision task. The dependent variable is the choice tendency between two options which have the same QALYs but different life quality. Results: When facing with the options that had the same QALYs, the aged tended to choose low quality and long length life options compared with the options that had high quality and short length life. When facing with the options that had the same QALYs, youths and the aged groups both tended to choose high quality life and short length options when making decisions for themselves, whereas for family and for unfamiliar others, they tended to choose low quality but the length of the long life options. Conclusion: In the medical situation, decision maker will make a trade-off between the life quality and life length. What's more, life quality and life length will be valued different while deciding for self and others in this medical situation.
