本研究目的在探討影響德國麻疹血清抗體陰性之育齡婦女未來補施打意願與願付價格之相關因素。研究對象為2012～2013年臺北市婚後孕前健檢或2010～2012年於臺北市立聯合醫院產前檢查，德國麻疹抗體為陰性且尚未補施打者共89位婦女。本研究運用羅吉斯迴歸模型及多元迴歸分析，在控制其他因素下，探討影響德國麻疹陰性婦女未來補施打意願及願付價格之相關因素。研究結果發現，婦女自覺障礙性愈低，未來補接種的可能性愈高；此外，願付平均價格為新臺幣1,395.51元，標準差為新臺幣1,154.08元，而影響願付價格之重要因素為家戶月收入。根據研究結果，本研究提出兩個結論：一、未來補接種疫苗之意圖受自覺障礙性影響；二、願付價格高低則受家戶月收入影響。建議未來衛生教育策略應強化婦女克服補施打疫苗之障礙性；若採自費疫苗，則需考量降低財務障礙。

This study aims to examine the factors associated with the intention and the willingness of women to pay for the Measles, Mumps and Rubella (MMR) catchup vaccination. The research subjects comprised of 89 women whose rubella antibodies were negative during their preconception checkup by the Post-Marital Pre-Pregnancy Health Examinations, the Department of Health, Taipei City Government, from 2012 to 2013, or their prenatal care during 2010-2012, in the Taipei City hospital, and had never been vaccinated at the time of the survey. We used statistical methods such as ordinary least squares, and logistic regression models, to analyze the factors associated with the intention, and the WTP for an MMR vaccination, after controlling for other variables. The result showed that the lower the perceived barriers, the more likely women would be to have an MMR in the future. Moreover, the significant factor affecting the WTP was their monthly household income. Our study suggested that the self-perceived barrier is an important factor affecting the intention of the catch-up MMR vaccine. Therefore, willingness to pay is affected by the women’s monthly household income. The health education program needs to empower women who would not normally be able to overcome numerous barriers of being vaccinated in order to increase their intention to proceed with the vaccination. If the vaccination is not free, then the government should consider different ways of reducing the financial accessibility for these lower socioeconomic groups.
