Currently, there are many diagnostic self-tests on body materials available to consumers. The aim of this study was to assess the effect of an online decision aid on diagnostic self-testing for cholesterol and diabetes on knowledge among consumers with an intention to take these tests. A randomized controlled trial was designed. A total of 1259 consumers with an intention to use a diagnostic cholesterol or diabetes self-test were selected from an existing Dutch Internet panel. The intervention group was invited to view an online decision aid offering general information on self-testing and test-specific information on cholesterol and diabetes self-testing, including indications for testing, how to perform the test and interpreting the result. The placebo condition consisted of a limited information sheet. Multiple regression analysis showed that the knowledge level in the diabetes arm was higher in the intervention group than in the control group (B = 0.657; 95% CI, 0.011-1.303), as was the number of participants with an informed choice (OR, 1.672; 95% CI, 1.134-2.465). No differences were found in the cholesterol arm. Consumers who are considering doing a self-test should have access to independent information on self-testing and be encouraged to read this information.

目前，消费者可以获得许多针对身体材料的诊断自测产品。本研究的目的是评估在线决策辅助工具对胆固醇和糖尿病诊断自测的影响，以及对有意进行这些测试的消费者知识水平的影响。设计了一项随机对照试验。从现有的荷兰互联网面板中选取了总共1259名有意使用胆固醇或糖尿病诊断自测产品的消费者。干预组被邀请查看一个在线决策辅助工具，该工具提供有关自测的一般信息以及胆固醇和糖尿病自测的特定测试信息，包括测试指征、如何进行测试以及解读结果。安慰剂组则是一份有限的信息表。多元回归分析显示，干预组糖尿病部分的知识水平高于对照组（B = 0.657；95%置信区间，0.011 - 1.303），做出明智选择的参与者数量也是如此（比值比，1.672；95%置信区间，1.134 - 2.465）。在胆固醇部分未发现差异。考虑进行自测的消费者应该能够获取有关自测的独立信息，并被鼓励阅读这些信息。
