Protocol - Health Quality Index for Economic Evaluations - Adult
The EQ-5D-3L is a standardized instrument for use as a measure of health outcomes. The EQ-5D-3L is applicable to a wide range of health conditions and treatments; it provides a simple descriptive profile and a single index value for health status. This instrument offers three levels of answers: no problems, some problems, or extreme problems.
Note: Licensing fees are determined by the EuroQol Executive Office on the basis of the user information provided on the registration form. The amount is dependent on the type of study, funding source, sample size, and number of requested languages. You are not obligated to purchase by registering.
See EQ-5D-3L User Guide for instructions and scoring.
The EQ-5D-3L self-reported questionnaire includes a descriptive system and the EQ visual analogue scale (EQ VAS). The descriptive system comprises five dimensions:
- Usual Activities
Each dimension has three levels:
- No problems
- Moderate problems
- Extreme problems
For the descriptive system, the respondent is asked to indicate his or her health state by marking the most appropriate statement in each of the three dimensions. This decision results in a one-digit number expressing the level selected for that dimension. The digits for three dimensions can be combined in a three-digit number describing the respondent’s health state.
The visual analogue scale records the respondent’s self-rated health on a 20 cm vertical, visual analogue scale with endpoints labeled "the best health you can imagine" and "the worst health you can imagine." This information can be used as a quantitative measure of health, as judged by the individual respondents.
