Researchers have traditionally studied the effects of psychoactive drugs such as Cannabis in controlled laboratory settings or relied on retrospective self-reports to measure impairment. However, advances in technology afford opportunities to conduct assessments remotely.
We considered whether objective click-stream data (time and number of clicks spent on a webpage) during an online survey could supplement self-reports of substance use problems.
The clickstream data of participants (n = 236) were examined as they completed an online study which included validated psychometric tests (Cannabis Use Disorders Identification Test-Revised, Grit-O, Kessler Psychological Distress Scale, and Brief Self Control Scale). Clickstream data were compared to self-reported Cannabis use.
People reporting Cannabis use within the last 4 weeks required more time and more clicks to complete the online survey, and this was specifically associated with reported frequency of use, duration of impairment, and problems with memory and concentration. Longer amounts of time and more clicks on the online questionnaire were associated with more recent Cannabis use rather than demographic factors or stimulant use.
These results imply clickstream data remotely detected indecision or other deficits associated with previous Cannabis use.
研究人员传统上在受控的实验室环境中研究大麻等精神活性药物的影响，或者依赖回顾性自我报告来衡量损伤。然而，技术的进步为远程评估提供了机会。
我们考虑了在在线调查期间，客观的点击流数据（在网页上花费的时间和点击次数）是否可以补充物质使用问题的自我报告。
在参与者（n=236）完成包括经过验证的心理计量测试（修订后的大麻使用障碍识别测试、坚韧-O、凯斯勒心理困扰量表和简短自我控制量表）的在线研究期间，检查了点击流数据。点击流数据与自我报告的大麻使用情况进行了比较。
在过去 4 周内报告使用大麻的人完成在线调查需要更多的时间和更多的点击，这与报告的使用频率、损伤持续时间以及记忆和注意力问题特别相关。在在线问卷上花费的时间和点击次数越多，与最近的大麻使用相关，而与人口统计学因素或兴奋剂使用无关。
这些结果表明，点击流数据远程检测到与以前的大麻使用相关的决策困难或其他缺陷。
