The role of bias in assessments of personal susceptibility to threat is a central concept in research on perception of risk. The current study aimed to clarify the association between perceived personal susceptibility to infection with HIV/AIDS and injecting risk behaviour with injecting drug-users' perception of the baseline rate of infection with HIV/AIDS. 1262 injecting drug-users from Australian cities were interviewed. The injecting drug-users were divided into high- and low-risk groups depending on the HIV/AIDS risk associated with their injecting behaviour. Subjects were subdivided into low-, medium-, and high-perceived personal susceptibility groups. Analysis indicated that injecting drug-users in the high-risk group underestimated the prevalence of HIV/AIDS infection relative to those in the low-risk group and that perceived personal susceptibility was rationally related to estimates of the baseline rate of infection.
偏差在个人对威胁易感性评估中的作用是风险认知研究中的一个核心概念。当前研究旨在阐明注射吸毒者对感染艾滋病毒/艾滋病的个人易感性认知与注射风险行为之间的关联，以及注射吸毒者对艾滋病毒/艾滋病基线感染率的认知。对来自澳大利亚各城市的1262名注射吸毒者进行了访谈。根据与他们注射行为相关的艾滋病毒/艾滋病风险，将注射吸毒者分为高风险组和低风险组。受试者又被细分为低、中、高个人易感性认知组。分析表明，相对于低风险组的注射吸毒者，高风险组的注射吸毒者低估了艾滋病毒/艾滋病感染的流行率，并且个人易感性认知与感染基线率的估计值存在合理关联。
