 The Global Burden of Disease, GBD, study evaluates the impact of diseases, injuries, and risk factors on health by using disability-adjusted life years, dailies, which require a set of disability weights to quantify the level of health associated with non-fatal outcomes. The objective of this study was to estimate disability weights for the GBD 2013 study. To achieve this, we analyzed data from new web-based surveys completed by participants aged 18 to 65 years in four European countries between September 23, 2013 and November 11, 2013. We combined this data with previously collected information from the GBD 2010 disability weights measurement study. The surveys used paired comparison questions where respondents compared two hypothetical individuals with different health states and specified which person they deemed healthier. We analyzed the paired comparison data using probit regression analysis and rescaled them. This article was authored by Professor Joshua A. Salomon, PhD, Juanita A.
