目的:考察医疗情景中不确定性容忍度和决策者角色对医疗决策的影响。方法:采用2(不确定性容忍度:高/低)×2(决策者角色:自我/他人)被试间实验设计,239名临床专业大学生被分为两组完成医疗决策任务。结果:不确定性容忍度对医疗决策影响边缘显著,高容忍度者比低容忍度者更倾向手术方案。决策者角色对医疗决策影响显著,与给他人建议相比,自我决策时更倾向手术方案。为自我决策时高容忍度者比低容忍度者更倾向手术方案,给他人建议时两者选择无显著差异;高容忍度者为自我决策比给他人建议更倾向手术方案,而低容忍度者自我-他人决策差异不显著。结论:不确定性容忍度和决策者角色对医疗决策存在交互影响。
OBJECTIVE: To investigate the impact of uncertainty tolerance and decision-maker role on medical decision-making in medical settings. METHODS: Two inter-laboratory experimental designs of 2 (uncertainty tolerance: high / low) × 2 (decision maker role: self / others) were used. 239 clinical majors were divided into two groups to complete the medical decision-making task. Results: Uncertainty tolerance has a significant impact on medical decision-making, and high tolerance patients are more inclined to surgery plans than low tolerance patients. The decision-maker’s role has a significant impact on medical decision-making, and tends to be more self-directed in terms of surgical options than to others. For self-decision-making, patients with higher tolerance than those with lower tolerance were more likely to have surgery plans. When giving advice to others, there was no significant difference between the two choices. Patients with high tolerance were more likely to self-decision than others, Self-decision-making differences are not significant. CONCLUSIONS: Uncertainty tolerance and decision maker roles have an interactive effect on medical decisions.
