Willingness to pay for antihypertensive therapy--results of a Swedish pilot study.

In this methodological study the results of a Swedish pilot study about willingness to pay for antihypertensive therapy are presented. The aim of the study was to test the feasibility of the contingent valuation (CV) method in this area. Open-ended and discrete CV questions were compared in a mail questionnaire. The open-ended CV question did not work well. The answers to the discrete question, analysed by logistic regression analysis, indicated a willingness to pay in the range SEK 2500-5000 per year for antihypertensive therapy. Further studies should be undertaken to explore the reliability and the validity of the CV method.
