Many individuals show negative attitudes toward the use of taxes for suicide prevention. Activities that enhance knowledge and awareness of suicide and suicide prevention may increase willingness to pay (WTP) for suicide prevention. WTP is the amount that a consumer will pay for a product or service. The present study examined the influence of educational activities on enhancing knowledge and awareness of suicide and its prevention on WTP. We conducted a quasi-experimental study to examine the influence of lectures on suicide by comparing the amount of change in WTP between two groups over the same period: an intervention group (n = 92) comprising students who participated in the lectures and a control group (n = 128) comprising general university students recruited through an Internet-based survey. A t-test showed that the amount of change was significantly larger in the intervention group (t (152.31) = 2.25, p = .026). Ordinal logistic regression analysis showed that increased WTP was significantly correlated with an annual household income of JPY 4-6 million or higher. It may be appropriate to conclude that participation in lectures about suicide is effective in increasing WTP for suicide prevention.
许多人对利用税收来预防自杀持消极态度。提高对自杀和自杀预防的认识和知识的活动可能会增加对自杀预防的支付意愿（WTP）。WTP 是消费者为产品或服务支付的金额。本研究考察了教育活动对提高对自杀及其预防的认识和知识，从而对 WTP 的影响。我们通过比较同一时期两组之间 WTP 变化量来进行一项关于自杀的讲座的准实验研究：干预组（n=92）由参加讲座的学生组成，对照组（n=128）由通过互联网调查招募的普通大学生组成。t 检验显示干预组的变化量明显更大（t(152.31)=2.25，p=.026）。有序逻辑回归分析显示，WTP 的增加与年收入 400 万至 600 万日元或更高显著相关。可以得出结论，参加关于自杀的讲座可以有效提高对自杀预防的支付意愿。
