Utility measures are preference-based measures of health-related quality of life.
Multi-attribute utility measures are preference-based health-related quality of life measures that have been developed to inform economic evaluations of health care interventions.
Primary outcome measures were preference and ad libitum consumption (with a maximum of 200 g) of both vegetable products (LE), measured before, shortly after the intervention period, and 2 and 6 months following conditioning to assess longer-term effects.
The primary outcome measure was preferences for care if they developed advanced dementia categorised as four options (life prolonging, limited, comfort, or uncertain).
Utilities are preference scores measured under conditions of uncertainty and utility functions convert descriptive information into utility scores.
Utility values (also called preference measures) are quantitative expressions of preference for given health states.
These measures are considered time preference proxies.
To quantify the impact of insomnia severity in economic studies such as cost utility analyses (CUA), preference-based measures are required to capture patient preferences for a particular health state [ 26].
Value scores are preferences measured under certainty.
While these preference measures are easy to obtain, they have methodological weaknesses.
Almlund et al. (2011), for example, point out that any empirical associations are not consistent across studies, and often preference measures are uncorrelated with intuitively similar personality traits.
