由于研究设计和统计方法的问题，关于物质使用的日常日记研究中是否存在测量反应性的争论仍然悬而未决。本研究提出了一种时变效应模型（TVEM），该模型用数据确定的非参数函数来表征物质使用行为的轨迹，而不是强加假定的参数函数。它还允许研究人员研究测量反应性不仅对使用物质的可能性而且对物质使用量的影响。 TVEM 用于分析从一项实验中收集的有关酒精和大麻使用的日记数据，该实验将 2014 年至 2016 年间密歇根州的 307 名参与者随机分为每日和每周评估计划。这项研究发现了酒精使用的短期测量反应性，但没有发现大麻使用的显着反应性影响。每日饮酒组在评估的第一周戒酒的几率较小，但预期饮酒量较低，但到第二周就消失了。结果表明，虽然日常自我监测可能会对几天内波动的物质使用行为（例如饮酒）产生短期反应，但它不会影响相当一致的物质使用行为（例如大麻使用）。我们的研究结果表明，虽然每日监测饮酒可能会促使人们在开始饮酒后减少饮酒量，但也可能会激起他们开始饮酒的欲望。然而，这两种效应往往只持续一周，因为参与者在第二周就适应了监测。
The debate about whether measurement reactivity exists in daily diary research on substance use is still unsettled due to the issues of study design and statistical methodology. This study proposes a time-varying effect model (TVEM) that characterizes the trajectory of substance use behaviors with nonparametric functions determined by the data rather than imposes presumed parametric functions. It also allows researchers to investigate the effect of measurement reactivity on not only the likelihood of using substances but also the amount of substance use. The TVEM was applied to analyze diary data on alcohol and marijuana use collected from an experiment, which randomized 307 participants in Michigan into daily and weekly assessment schedules during 2014-2016. This study found short-term measurement reactivity on alcohol use, but did not find a significant reactivity effect on marijuana use. The daily group had smaller odds of abstinence from drinking but lower expected drinking quantity in the first week of assessment, which dissipated by the second week. The results indicate that although daily self-monitoring could have short-term reactivity on substance use behaviors that tend to fluctuate across days, such as alcohol use, it does not affect substance use behaviors that are quite consistent, such as marijuana use. Our findings imply that although daily monitoring of drinking may motivate people to reduce the quantity consumed once they start to drink, it may also arouse their desire to start drinking. Yet, both effects tend to last only one week, as participants accommodate to the monitoring by the second week.
