Abstract：
BACKGROUND: Increasing rates of sexually transmitted infections (STIs) over the past decade underscore the need for early testing and treatment. Communicating HIV/STI risk effectively can promote individuals\' intention to test, which is critical for the prevention and control of HIV/STIs. We aimed to determine which visual displays of risk would be the most likely to increase testing or use of prevention strategies.
METHODS: A vignette-based cross-sectional survey was conducted with 662 clients (a median age of 30 years (IQR: 25-36), 418 male, 203 female, 41 other genders) at a sexual health clinic in Melbourne, Australia, between February and June 2023. Participants viewed five distinct hypothetical formats, presented in a randomised order, designed to display the same level of high risk for HIV/STIs: icon array, colour-coded risk metre, colour-coded risk bar, detailed text report and guideline recommendation. They reported their perceived risk, concern and intent to test for each risk display. Associations between the format of the risk display and the intention to test for HIV/STI were analysed using logistic regression.
RESULTS: About 378 (57%) of participants expressed that the risk metre was the easiest to understand. The risk metre (adjusted OR (AOR)=2.44, 95% CI=1.49 to 4.01) and risk bar (AOR=2.08, CI=1.33 to 3.27) showed the greatest likelihood of testing compared with the detailed text format. The icon array was less impactful (AOR=0.73, CI=0.57 to 0.94). The risk metre also elicited the most concern but was the most preferred and understood. High-risk perception and concern levels were strongly associated with their intention to have an HIV/STI test.
CONCLUSIONS: Displaying risk differently affects an individual\'s perceived risk of an HIV/STI and influences their intention to test.

摘要：
背景：在过去十年中，性传播感染（STIs）的发病率不断上升，这凸显了早期检测和治疗的必要性。有效地传播艾滋病毒/性传播感染风险可以促进个人检测的意愿，这对于预防和控制艾滋病毒/性传播感染至关重要。我们的目的是确定哪些风险的视觉显示最有可能增加测试或预防策略的使用。
方法：对662名客户进行了基于小插图的横断面调查（年龄中位数为30岁（IQR：25-36），418名男性,203女性,其他41种性别）在墨尔本的性健康诊所，澳大利亚,2023年2月至6月。参与者查看了五种不同的假设格式，以随机顺序呈现，旨在显示相同水平的艾滋病毒/性传播感染的高风险：图标阵列，彩色编码风险表，颜色编码的风险栏，详细的文本报告和指南建议。他们报告了他们的感知风险，对每个风险显示进行测试的关注和意图。使用逻辑回归分析了风险显示格式与HIV/STI测试意图之间的关联。
结果：约378（57%）的参与者表示风险量表是最容易理解的。与详细的文本格式相比，风险量表（调整后的OR（AOR）=2.44，95％CI=1.49至4.01）和风险栏（AOR=2.08，CI=1.33至3.27）显示出最大的测试可能性。图标阵列的影响较小（AOR=0.73，CI=0.57至0.94）。风险量表也引起了最多的关注，但也是最受欢迎和最被理解的。高风险感知和关注水平与他们进行HIV/STI测试的意图密切相关。
结论：显示不同的风险会影响个人对HIV/STI的感知风险，并影响他们的测试意图。
