As explained in the journal article below, this value set for New Zealand was developed using a special 1000minds tool for creating personal and social value sets – i.e. for each individual and the population 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 was distributed in an online survey in February and March 2018 to a representative sample of NZ adults, with ethics approval from the University of Otago Human Ethics Committee.
The tool’s extensive checks of each participant’s data quality 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 tool is being developed to create a NZ value set for the SF-6D, expected to be available by the end of 2022.
The following link is a demo of a 1000minds survey for creating your own personal EQ-5D-5L value set (and that could potentially contribute to a social value set, e.g. for a country).
Significance of correlations
You can look up the significance of correlations between HRQoL value sets, such as the EQ-5D, using the tables produced by our significance calculator.
