在美国，男男性行为者 (MSM) 是艾滋病毒检测率较低的弱势群体。 HIV 检测的多种具体属性可能会影响 HIV 检测意愿 (WTT)。确定影响患者关于 HIV WTT 决策的具体属性对于确保提高 HIV 检测的采用率至关重要。这项研究通过使用联合分析来检查 HIV 的 WTT，联合分析是一种系统地估计消费者跨离散属性偏好的创新方法。 HIV 的 WTT 在八种假设的 HIV 检测场景中进行评估，这些场景涉及七个二分属性：地点（家庭与诊所）、价格（免费与 50 美元）、样本采集（手指刺破与血液）、结果的及时性（立即与 1-2 周）、隐私（匿名与保密）、结果给出（通过电话与亲自）以及咨询类型（手册与面对面）。从洛杉矶一家提供 HIV 检测服务的社区组织招募了 75 名 MSM 来参与联合分析。 HIV 的 WTT 评分基于 100 分制。八种假设的 HIV 检测场景的得分范围为 32.2 至 80.3。 HIV 检测的价格（免费 vs. 50 美元）对 WTT 的影响最大（影响评分=31.4，SD=29.2，p<.0001），其次是结果的及时性（立即 vs. 1-2 周）（影响评分=13.9，SD=19.9，p=<.0001）和检测地点（家庭与诊所）（影响评分=10.3，SD=22.8， p=.0002)。其他艾滋病毒检测属性的影响并不显着。联合分析方法能够直接评估 HIV 检测偏好，并确定显着影响 MSM 中 HIV 的 WTT 的特定属性。该方法提供了经验证据，支持 FDA 新批准的非处方艾滋病毒家庭检测试剂盒的潜在采用，并立即产生结果，并对试剂盒的成本提出了警告。
Men who have sex with men (MSM) in the United States represent a vulnerable population with lower rates of HIV testing. There are various specific attributes of HIV testing that may impact willingness to test (WTT) for HIV. Identifying specific attributes influencing patients’ decisions around WTT for HIV is critical to ensure improved HIV testing uptake. This study examined WTT for HIV by using conjoint analysis, an innovative method for systematically estimating consumer preferences across discrete attributes. WTT for HIV was assessed across eight hypothetical HIV testing scenarios varying across seven dichotomous attributes: location (home vs. clinic), price (free vs. $50), sample collection (finger prick vs. blood), timeliness of results (immediate vs. 1–2 weeks), privacy (anonymous vs. confidential), results given (by phone vs. in-person), and type of counseling (brochure vs. in-person). Seventy-five MSM were recruited from a community based organization providing HIV testing services in Los Angeles to participate in conjoint analysis. WTT for HIV score was based on a 100-point scale. Scores ranged from 32.2 to 80.3 for eight hypothetical HIV testing scenarios. Price of HIV testing (free vs. $50) had the highest impact on WTT (impact score=31.4, SD=29.2, p<.0001), followed by timeliness of results (immediate vs. 1–2 weeks) (impact score=13.9, SD=19.9, p=<.0001) and testing location (home vs. clinic) (impact score=10.3, SD=22.8, p=.0002). Impacts of other HIV testing attributes were not significant. Conjoint analysis method enabled direct assessment of HIV testing preferences and identified specific attributes that significantly impact WTT for HIV among MSM. This method provided empirical evidence to support the potential uptake of the newly FDA-approved over-the-counter HIV home-test kit with immediate results, with cautionary note on the cost of the kit.
