This enables administrators or decision makers to compare and evaluate programs that address different diseases or populations. To compare very different alternatives, measures of program benefits must be comprehensive, including all possible direct effects, whether intended or not.

The most frequently used measures in this class include the EuroQOL 5D (EQ-5D), the Health Utilities Index measures (HUI), and the Quality of Well-Being Scale measures (QWB and QWB-SA). The Quality of Well-Being (QWB) scale is a generic, preference-based measure of HRQOL with well-established psychometric properties in a wide variety of diseases and subgroups. In response to limitations of the QWB, a self-administered version of the QWB (QWB-SA) has been developed ...
