尽管暴露前预防(PrEP)的有效性有据可查，但在高危人群中PrEP的摄取率仍然很低。2015年疾控中心的报告估计，美国约有120万人有PrEP的迹象。然而，目前只有49,158人，即4%的目标人口在使用PrEP。制定一个全面的理论框架可以促进优化PrEP摄取的努力，该框架可用于了解摄取不良的原因，并制定干预措施，以最大限度地提高PrEP的摄取和依从性。本文回顾了有关PrEP吸收的相关研究，并提出了在信息-动机-行为技能(IMB)模型框架内组织的研究结果。在PrEP吸收的背景下，IMB模型断言，只要高危群体对PrEP有充分的了解，有动力根据他们的知识采取行动，并拥有必要的行为技能来寻找和启动PrEP方案，他们将成功地克服障碍，启动和坚持PrEP。本文提出了一种对PrEP摄取的IMB模型进行修正，为从相关研究中提取的修正IMB模型提供了经验支持，并讨论了其在PrEP摄取干预中的应用。
Despite documented effectiveness of pre-exposure prophylaxis (PrEP), PrEP uptake remains low among at-risk populations. The 2015 CDC report estimates that about 1.2 million people in the US have indications for PrEP. However, only 49,158 or 4% of the targeted population are currently using PrEP. Efforts to optimize uptake of PrEP may be facilitated by the development of a comprehensive theoretical framework which can be used to understand reasons for poor uptake and to develop interventions to maximize PrEP uptake and adherence. This article reviews research on correlates of PrEP uptake and presents findings organized within an Information-Motivation-Behavioral Skills (IMB) model framework. In the context of PrEP uptake, the IMB model asserts that to the extent that at-risk groups are well-informed about PrEP, motivated to act on their knowledge, and have necessary behavioral skills to seek out and initiate PrEP regimen, they will successfully overcome obstacles to initiate and adhere to PrEP. The article proposes an adaptation the IMB model for PrEP uptake, provides empirical support for the adapted IMB model extracted from related research, and discusses its application in PrEP uptake interventions.
