在评估发展中国家扩大艾滋病毒检测和咨询服务是否会导致采取减少风险战略和降低艾滋病毒发病率时，个人对感染艾滋病毒的主观预期对有关其艾滋病毒状况的信息的反应是一个关键方面。为了研究这一问题，我们使用了马拉维农村地区的纵向数据集，该数据集将艾滋病毒感染的创新性概率期望与艾滋病毒检测的随机设计相结合，以调查向个人提供有关其艾滋病毒状况的信息是否会在艾滋病毒检测两年后对其自身感染状况产生更准确的信念。我们发现，了解自己的艾滋病毒阳性状态对自己感染艾滋病毒的中期主观信念没有影响。我们还表明，了解自己的HIV阴性状态会导致对自己感染的后续信念更高，以及对HIV状态的更大预测误差。
The response of an individual’s subjective expectations about being infected with HIV to information about his/her HIV status is a critical aspect in assessing whether expansion of HIV testing and counseling services in developing countries will result in the adoption of risk reduction strategies and reduced HIV incidence. To investigate this issue, we use a longitudinal dataset from rural Malawi that combines innovative probabilistic expectations about HIV infection with a randomized design for HIV testing to investigate whether providing an individual with information about his/her HIV status results in more accurate beliefs about his/her own infection status two years after the HIV test. We find that learning about one’s HIV-positive status has no impact on medium-term subjective beliefs about one’s own HIV infection. We also show that learning one’s HIV-negative status results in higher subsequent beliefs about one’s own infection, as well as larger prediction errors about one’s HIV status.
