OBJECTIVES: This study aims 1) to compare utility values obtained from two different measurement techniques, namely Time-Traded-Off (TTO) and Visual Analogue Scale (VAS), and 2) to explore the “state worse than death” associated with blindness, paralysis and allergy scenarios.METHODS: Face-to-face interview was conducted in 162 general Thai people, aged between 15-65 years from Pathum-Thani province. Each respondent was randomly asked for the utility values associated with one of the following health scenario; blindness, paralysis, and allergy. Two measurement techniques, namely time traded off (TTO) and visual analogue scale (VAS) were evaluated in this study. RESULTS:           In blindness scenario, means utility obtained from TTO method were significantly higher than those obtained from VAS method for both bilateral blindness (0.20 VS 0.12) and unilateral blindness (0.65 VS 0.43). On the other hand, means utility obtained from VAS method was significantly higher than those obtained from TTO method in paraplegia (0.40 VS 0.20) and quadriplegia (0.16 VS 0.04). Concerning “state worse than death”, 54% (36 persons), and 3% (2 persons) indicated that being bilateral blinded and unilateral blinded were worse than death, respectively.  On the contrary, 82% (56 persons), and 50% (34 persons) thought that being in quadriplegia, and paraplegia state were worse than death. Only 7.4% - 22% of the respondent indicated that having allergy were worse than death. CONCLUSIONS: According to the study, different techniques yielded significantly different utility value. Whether the utility obtained from VAS or TTO techniques is higher is still inconclusive. More than 50% of the respondents indicated that being bilateral blinded or being in quadriplegia condition was worse than death.
