We conducted a discrete choice experiment (DCE) and quantified preferences for HIV testing among South African youth (Nov 2018 to Mar 2019). Six attributes and levels were identified through qualitative methods: source of HIV information; incentive amount and type; social support; testing method; and location. Each participant chose one of two options that comprised six attributes across 18 questions. Conditional logistic regression estimated the degree of preference [β]. Of 130 participants, median age was 21 years (interquartile range 19-23 years), majority female (58%), and 85% previously tested for HIV. Testing alone over accompanied by a friend (β = 0.22 vs. - 0.35; p < 0.01); SMS text over paper brochures (β = 0.13 vs. - 0.10; p < 0.01); higher incentive values (R50) over no incentive (β = 0.09 vs. - 0.07; p = 0.01); and food vouchers over cash (β = 0.06 vs. β = - 0.08; p = 0.01) were preferred. Testing at a clinic or home and family encouragement were important. Tailoring HTS to youth preferences may increase HIV testing.
我们开展了一项离散选择实验（DCE），并量化了南非青年对 HIV 检测的偏好（2018 年 11 月至 2019 年 3 月）。通过定性方法确定了六个属性和水平：HIV 信息来源；激励金额和类型；社会支持；检测方法；和位置。每个参与者从包含 18 个问题的六个属性的两个选项中选择一个。条件逻辑回归估计偏好程度 [β]。在 130 名参与者中，中位数年龄为 21 岁（四分位距为 19-23 岁），大多数为女性（58%），85%之前曾接受过 HIV 检测。单独检测（β=0.22 对-0.35；p<0.01）；短信文字比纸质小册子（β=0.13 对-0.10；p<0.01）；更高的激励价值（R50）而不是没有激励（β=0.09 对-0.07；p=0.01）；以及食品券而不是现金（β=0.06 对β=-0.08；p=0.01）更受欢迎。在诊所或家庭进行检测以及家庭鼓励很重要。根据年轻人的偏好来调整 HTS 可能会增加 HIV 检测。
