Given the potential advantages of online assessment of implicit alcohol-related cognitive processes, the goal of this study was to empirically validate the online administration of the implicit association test (IAT). First, we examined whether an Internet-delivered IAT programmed in Flash can be as effectively used to assess implicit alcohol-related associations as equivalent IAT versions that are programmed in local lab software, such as Inquisit. Second, participants performed the IAT versions once in the controlled laboratory setting and once on their home computers via the Internet. Findings with the alcohol IAT versions were robust and did not vary systematically with respect to setting (home or lab) or assessment software (Flash or Inquisit). Importantly, there were also indications that IAT versions performed at home were more strongly related to explicit measures and drinking behavior than were lab-based IAT versions. Together, these findings demonstrate that the alcohol IAT can be validly administered online via participants' home computers.
鉴于在线评估与酒精相关的内隐认知过程具有潜在优势，本研究的目的是通过实证验证内隐联想测验（IAT）的在线施测。首先，我们考察了用Flash编程的互联网版IAT是否能像用本地实验室软件（如Inquisit）编程的等效IAT版本一样有效地用于评估与酒精相关的内隐联想。其次，参与者在受控的实验室环境中进行一次IAT版本测试，并通过互联网在自己的家用电脑上进行一次测试。酒精IAT版本的测试结果很可靠，在测试环境（家中或实验室）或评估软件（Flash或Inquisit）方面没有系统差异。重要的是，也有迹象表明，在家中进行的IAT版本测试比基于实验室的IAT版本测试与外显测量和饮酒行为的相关性更强。总之，这些结果表明，酒精IAT可以通过参与者的家用电脑有效地在线施测。
