包括持续时间 (DCEd) 估值方法在内的离散选择实验与EQ-5D-5L仪器的复合时间权衡 (cTTO) 和EuroQol估值技术 (EQ-VT) 密切一致,证实了它们的可比性.
科学领域:
- 卫生经济学 卫生经济学
- 心理测量 心理测量 心理测量
- 估值方法 估值方法
背景情况:
- 包括持续时间属性 (DCEd) 在内的离散选择实验是评估与健康有关的生活质量工具的新兴方法.
- 对于DCEd和已建立的方法,如复合时间权衡 (cTTO) 和EuroQol估值技术 (EQ-VT) 对于EQ-5D-5L仪器的直接比较是有限的.
- 了解DCEd与cTTO/EQ-VT的可比性对于其在健康评估研究中的采用至关重要.
研究的目的:
- 直接比较DCEd的估值结果与cTTO和EQ-VT对于EQ-5D-5L仪器.
- 评估DCEd和cTTO/EQ-VT估值方法之间的一致性和一致性.
- 评估DCEd作为评估健康相关生活质量指标的方法的实用性.
主要方法:
- 从特立尼达和多巴哥的1079名受访者收集了EQ-VT和cTTO数据,这些受访者评估了EQ-5D-5L.
- 从970名受访者的单独样本中收集了DCEd数据,使用了分三任务.
- 对EQ-VT数据应用了回归模型;使用混合逻辑模型分析了DCEd数据,并通过分散图和Bland-Altman图进行了值比较.
主要成果:
- 在cTTO/EQ-VT和DCEd模型中,维度重要性排序相同,疼痛/不适最重要,通常活动最不重要.
- 最糟糕的健康状况 (55555) 的值是可比的:cTTO/EQ-VT 的值为-0.52到-0.69,非线性混合逻辑 DCEd 模型的值为-0.543.
- 分散图和Bland-Altman图显示了cTTO/EQ-VT和基于DCEd的估计之间的优异一致.
结论:
- 综合时间权衡/EuroQol估值技术和离散选择实验,包括持续时间 (DCEd) 估值,当DCEd考虑非线性时间偏好时,会产生类似的结果.
- 尺寸重要性和规模的相同排序表明,这两种方法都测量了相同的潜在健康评估结构.
- DCEd是一种可比且可靠的方法,用于评估与健康有关的生活质量仪器,如EQ-5D-5L.

Crossover Experiments
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.
Decision Making: Traditional Method
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...
