EQ-5D-5L value set for NZ
1000minds was used to create the NZ Value Set for the EQ-5D-5L.
You can download this value set (3125 values) as an Excel spreadsheet (also announced at the NZ Algorithms Hub).
As explained in detail in the article below, this value set was developed using a special 1000minds tool for creating personal and social value sets, i.e. for each individual and populations overall.
The tool implements the PAPRIKA method, a type of adaptive discrete choice experiment (DCE), and a binary search algorithm to identify any health states worse than dead. The tool also includes extensive checks of the quality of each participant’s data.
The tool was distributed in an online survey in February-March 2018 to a representative sample of NZ adults, with ethics approval from the University of Otago Human Ethics Committee.
As well as the DCE and binary-search questions, the survey asked participants to rate their own health on the EQ-5D-5L questionnaire and provide their socio-demographic and background information and feedback about the tool and survey overall.
Most people completed the survey in less than 10 minutes, including answering 20 DCE questions each on average, and indicated they found the survey user-friendly.
The tool’s extensive data-quality checks resulted in a sub-sample of 2468 “high-quality” participants, whose personal value sets were, in effect, averaged to create a social value set: the NZ Value Set for the EQ-5D-5L.
Intended users of the value set include health policy-makers and researchers.
A similar 1000minds tool was developed to create a SF-6Dv2 value set for NZ.

Significance of correlations
You can look up the significance of correlations between HRQoL value sets, such as the EQ-5D-5L, etc, using the tables produced by our significance calculator.
