The lack of empirical data on societal and patient preference-based utility weights for drug-related health states and consequences limits the application of costutility analysis (CUA) to these common problems. To address this issue, we developed and pilot-tested a spectrum of opiate, cocaine, and marijuana related health state descriptions. Using a fractional factorial design, we then presented the health state descriptions to study participants recruited from the general population and from the drug treatment population for completion of Visual Analogue Scale, Time Trade-Off, and Standard Gamble exercises. We will present the results of these assessments and compare the advantages and disadvantages of these direct methods to indirect methods (e.g. EQ-5D, SF-6D) that rely on multi-attribute utility theory. In addition, we will present data on the test-retest reliability, consistency, and discrimination of the direct utility measurements. The results of this project will be useful for quality-adjusted life-years calculation in future CUA of drug abuse treatment programs and for burden of disease estimates in populations.
