Should additional domains be added to the EQ-5D health-related quality of life instrument for community-based studies? An analytical descriptive study

Conclusions: The EQ-5D-3 L performed well, but the addition of domains such as Concentration and Sleep increased the explanatory power. The user needs to weigh the advantage of using the EQ-5D, which allows for the calculation of a single summary index, against the use of a set of domains that are likely to be more responsive to differences in HRQoL within community living respondents. The poor predictive power of the Self-Care and Usual Activities domains within this context needs to be further examined.
