There are three main EQ-5D instruments:
In addition to the classification system, each of the instruments also includes a visual analogue scale (EQ VAS). The EQ VAS records the respondent’s self-rated health on a visual analogue scale from 0 to 100, whereby 0 indicates ‘the worst health you can imagine’, and 100 ‘the best health you can imagine’. This information can be used as a quantitative measure of health as judged by the individual respondents.
EQ-5D User Guide
The EQ-5D User Guide has been developed in order to give users basic information on how to use the EQ-5D instrument. The EQ-5D User Guide is available for all EQ-5D instruments.
