One of the economic evaluation techniques involves calculation of willingness to pay (WTP) for a service to find out the value of that service from the clients' perspective. This study estimated WTP for both breast cancer and osteoporosis screening and comparatively examined the contributing factors. In fact, the comparisons served to provide an exact analysis of individual attitudes and behaviors in relation to screening programs for cancers and other diseases.
This study was first designed in six scenarios several questionnaires concerning individual breast cancer and osteoporosis screening cases, and determined the WTP median in each scenario between people in Kerman Province of Iran in 2016. Then, the demand function for breast cancer and osteoporosis screening was formulated. Moreover, the factors contributing to WTP were examined through various scenarios in Stata and econometric techniques.
The median and mean values of WTP in all the above scenarios were greater for breast cancer screening than for osteoporosis screening. Theoretically, the price assumed a minus sign whereas risk assumed a plus sign within the demand function formulated for both screening programs. Regarding the evaluated factors, age in breast cancer screening and risk of disease in osteoporosis screening were the major factors contributing to WTP.
Breast cancer screening was more valuable than osteoporosis screening program from the perspective of the subjects. The programs can be successfully designed by concentrating on patients' age groups in breast cancer screening and high-risk patients in osteoporosis screening.
经济评估技术之一涉及计算对一项服务的支付意愿（WTP），以便从客户角度找出该服务的价值。本研究估计了乳腺癌和骨质疏松症筛查的支付意愿，并对影响因素进行了比较研究。事实上，这些比较有助于对与癌症及其他疾病筛查项目相关的个人态度和行为进行精确分析。
本研究首先设计了六种情景，涉及若干关于个人乳腺癌和骨质疏松症筛查情况的问卷，并确定了2016年伊朗克尔曼省居民在每种情景下的支付意愿中位数。然后，构建了乳腺癌和骨质疏松症筛查的需求函数。此外，通过Stata中的各种情景和计量经济学技术，研究了影响支付意愿的因素。
在上述所有情景中，乳腺癌筛查的支付意愿中位数和平均值均高于骨质疏松症筛查。理论上，在为两个筛查项目构建的需求函数中，价格的系数为负，而风险的系数为正。在评估的因素中，乳腺癌筛查中的年龄和骨质疏松症筛查中的疾病风险是影响支付意愿的主要因素。
从受试者的角度来看，乳腺癌筛查比骨质疏松症筛查项目更有价值。通过关注乳腺癌筛查中的患者年龄组和骨质疏松症筛查中的高危患者，可以成功设计这些筛查项目。
