In the context of a randomized controlled trial (RCT) on HIV testing in the emergency department (ED) setting, we evaluated preferences for survey modality and data quality arising from each modality.
Enrolled participants were offered the choice of answering a survey via audio computer assisted self-interview (ACASI) or pen and paper self-administered questionnaire (SAQ). We evaluated factors influencing choice of survey modality. We defined unusable data for a particular survey domain as answering fewer than 75% of the questions in the domain. We then compared ACASI and SAQ with respect to unusable data for domains that address sensitive topics.
Of 758 enrolled ED patients, 218 (29%) chose ACASI, 343 chose SAQ (45%) and 197 (26%) opted not to complete either. Results of the log-binomial regression indicated that older (RR = 1.08 per decade) and less educated participants (RR = 1.25) were more likely to choose SAQ over ACASI. ACASI yielded substantially less unusable data than SAQ.
In the ED setting there may be a tradeoff between increased participation with SAQ versus better data quality with ACASI. Future studies of novel approaches to maximize the use of ACASI in the ED setting are needed.
在一项关于在急诊环境中进行 HIV 检测的随机对照试验（RCT）中，我们评估了每种模式下出现的调查模式偏好和数据质量。
入组的参与者可以选择通过音频计算机辅助自我访谈（ACASI）或纸笔自我管理问卷（SAQ）回答调查。我们评估了影响调查模式选择的因素。我们将特定调查领域的不可用数据定义为回答该领域少于 75%的问题。然后，我们比较了 ACASI 和 SAQ 在涉及敏感主题的领域的不可用数据。
在 758 名入组的 ED 患者中，218 名（29%）选择了 ACASI，343 名选择了 SAQ（45%），197 名（26%）选择不完成任何一种。二项逻辑回归的结果表明，年龄较大（每十年增加 1.08 倍）和教育程度较低的参与者（RR=1.25）更有可能选择 SAQ 而不是 ACASI。ACASI 产生的不可用数据明显少于 SAQ。
在 ED 环境中，SAQ 可能会增加参与度，而 ACASI 可能会提高数据质量，这两者之间可能存在权衡。需要进一步研究新的方法，以最大限度地在 ED 环境中使用 ACASI。
