“…Evidence from the few studies that have focused on WTP is difficult to interpret due to variability of concepts used, the small samples, and the small number of health states which do not allow for sound statistical testing (Thompson et a l, 1982(Thompson et a l, , 1984Thompson, 1986;O'Brien and Viramontes, 1994;Chestnut et al, 1996). Unless it is possible to improve the operationalisation of WTP it may have to be regarded as an unfeasible method.…”

Abstract-The objective of the study was to consider five methods for valuing health states with respect to their comparability (convergent validity, value functions) and reliability. Valuation tasks were per formed by 104 student volunteers using five frequently used valuation methods: standard gamble (SG), time trade-off (TTO), rating scale (RS), willingness-to-pay (WTP) and the paired comparisons method (PC). Throughout the study, the EuroQoI classification system was used to construct 13 health-state descriptions. Validity was investigated using the multitrait-multimethod (M TM M ) methodology. The extent to which results of one method could be predicted by another was examined by transformations. Reliability of the methods was studied parametrically with Generalis ability Theory (an A N O V A exten sion), as well as non-parametrically. Mean values for SG were slightly higher than TTO values. The RS could be distinguished from the other methods. After a simple power transformation, the RS values were found to be close to SG and TTO. Mean values of WTP were linearly related to SG and TTO, except at the extremes of the scale. However, the reliability of WTP was low and the number of incon sistencies substantial. Valuations made by the RS proved to be the most reliable. Paired comparisons did not provide stable results. In conclusion, the results of the parametric transformation function between RS and SG/TTO provide evidence to justify the current use of RS (with transformations) not only for reasons of feasibility and reliability but also for reasons o f comparability. A definite judgement on PC requires data of a complete design. Due to the specific structure of the correlation matrix which is inherent in valuing health states, we believe that full M TM M is not applicable for the standard analysis of health-state valuations.

“…Examples include paying for reductions in urinary incontinence symptoms [5] or reductions in angina symptoms [6]. Researchers are starting to branch out and ask WTP about other issues.…”

The goal of this study was to develop a willingness to pay (WTP) question for mammography that is appropriate for low income, ethnically-diverse women. Through qualitative research with 50 low income women of five ethnic groups we developed both a WTP question and a willingness to travel question (WTT). After being refined through interviews with 41 women, these questions were pilot tested on a random sample of 52 low income, ethnically-diverse women in the San Francisco area. Results show that the concepts underlying WTP and WTT were culturally appropriate to the five ethnicities in this study. Analyses generally confirm the validity of the WTP and WTT questions. As expected, WTP was associated with household income, perceived risk of cancer, and knowledge that one needs a mammogram even after a clinical breast examination. Despite the small samples, WTP varied among the ethnic groups. Additionally, WTT was moderately correlated with the natural log of WTP (r = 0.58, P < 0.001). These questions are now in use in a larger clinical trial and future analyses will explore willingness to pay and willingness to travel within and across the ethnic groups.

“…In addition, WTP for the inpatient treatment of myocardial infarction (MI) was also measured, for which hypertension is a major risk factor. While there have been several previous reports concerning WTP for the treatment of cardiovascular diseases in Sweden 16,17) and the United States, 18,19) this study is the first of its kind in Japan. We regard this study as being a pilot study of WTP measurement for our future studies of cost-benefit analysis in Japan's healthcare system.…”

SUMMARYRecently, application of the contingent valuation method (CVM) to health care is increasing to measure the willingness to pay (WTP) for specific medical services. In this study, we measured WTP for the outpatient treatment of hypertension and inpatient treatment of myocardial infarction (MI) in Japan's healthcare system, using CVM via an Internet questionnaire survey in 547 citizens aged 40 to 49 years. WTP was measured with the payment cards method from an ex post consumer based perspective. The payment vehicle was out-of-pocket copayment under public medical insurance. The participants were asked their preferences with respect to medical institutions, and 3 comprehensive characteristics were extracted from the requested information by principal component analysis.Categorical regression was performed to analyze the factors affecting WTP. The mean WTP for hypertension treatment was $75.03/month, and that for the treatment of MI was $8,928.70 ($1 = 105 Japanese yen). WTP for hypertension treatment was significantly high in married males and the group without symptoms, but was not associated with income. WTP for the treatment of MI was significantly high in the high-income group, married males, and the group with symptoms. Among the 3 principle components, "objective evaluation" was significantly associated with WTP for the treatment of MI. As for serious diseases such as MI, the income-associated differences in WTP suggest the necessity for reinforcement of the safety net for the low-income group. Although asymptomatic, hypertension requires continuous treatment. For such diseases, uniformly low copayment should be established irrespective of annual income. (Int Heart J 2006; 47: 273-286)
