EQ-5D-5L
目前只找到這篇由美國學者所發表之文章,但本研究的健康狀態的5個嚴重程度分類並非EuroQul Group的官方認證版本,試摘錄重點如下:
Psychometrics Comparison of the standard EQ-5D to a 5 Level Version in Cancer Patients
A. Simon Pickard, Maria C. De Leon,Thomas Kohlmann, David Cella,and Sarah Rosenbloom.
(Medical Care • Volume 45, Number 3, March 2007)
將EQ-5D描述系統的每個dimesion的嚴重程度量尺由3類擴大至5類之原因:
(1)可以改善描述系統本身的能力,可靠地區辨不同嚴重程度的健康狀態並偵測在健康狀態上的改變。
(2)根據調查程序模式,太少的回應選項會降低受訪者區辨不同健康嚴重程度的能力,但給予太多選項時,受訪者則可能無法可靠地區辨健康狀態的程度。
研究目的:
(1)是否由EQ-5D標準版(簡稱EQ-5D-3L)的3類選項擴大至5類(簡稱EQ-5D-5L)可增加描述系統的豐富性並改善對不同嚴重程度的健康狀態的區辨能力。
(2)檢測每個EQ-5D版本在癌症患者的心理計量特性。
工具:
美國英語版EQ-5D-3L與實驗版EQ-5D-5L(非EuroQol的官方版本)與標準版EQ-5D VAS.
本研究之EQ-5D-5L:
Level 1 ( ie, no problem)
Level 2 (“slightly” for anxiety/depression and “ slight” for the remaining 4 dimensions.)
Level 3 ( ie, some problem.)
Level 4 (“very” for anxiety/depression and “a lot” for the other 4 dimensions.)
Level 5 ( ie, extreme problem)
Discussion:
(1)擴充每個dimension選項的最大動機是因為可以改善對不同嚴重程度健康狀態的描述能力,減少樣本數的需求。 EQ-5D-3L的相對效率係數(relative efficiency ratio )為1.26,EQ-5D-3L需多出EQ-5D-5L 26%的樣本數才能與EQ-5D-5L達到相同的Power。
(2)EQ-5D-3L 與 EQ-5D-5L 兩者在癌症患者族群上都得到效度(validity)上的支持。
(3)本研究亦提供單一項目的面向結構(single item dimensional structure)的信度(reliability)支持。兩版本間約有5%的回答結果不一致(inconsistent),不一致的回答暗示著僅有非常少數比例的受訪者不了解訪問目的或缺乏足夠的練習。
未來方向:
(1)5-level EQ-5D較標準的3-level EQ-5D在癌症病患上具有較大區辨性,但運用在其他病患族群則更需要進一步資訊。
(2)本研究並未檢驗ordering effect, 未來研究應儘可能地將ordering effect納入研究中。
此研究為非正式版是因為文獻首頁標註
The views expressed in this work are the solely those of the authors and do not necessarily represent the views of the EuroQol Group. The 5L version of the EQ-5D was an experimental prototype and is not an officially recognized version distributed by the EuroQol Group.
此研究雖非EuroQoL官方正式研究不過卻有獲得EuroQul group部分經費的支持。
Letter From Paul Kind :
The EuroQoL Group is currently planning to increase the number of levels per dimension from 3 to 5. This will enlarge the descriptive classification and hence the problemsof valuation. A separate Task Force has been set up within the EuroQoL Group to tackle the design of new valuation methods suitable for the enlarged classification. We expect that this work will be completed in time for us to encourage and conduct new valuation studies in 2008.
This leaves researchers such as you and your colleagues in Taiwan with the task of conducting valuation studies on the existing 3-level descriptive system
