Researchers have long recognized the utility of the diary method for studying variations in thoughts, feelings, and behaviors. Drawing on the idea that daily events have consequences that are realized both "in the moment" and prospectively over time, we describe a conceptual and statistical framework emphasizing the temporal aspect of diary data. Including temporal effects (i.e., Lagged and concurrent × Lagged terms) expands the scope of the hypothesis being tested by allowing the researcher to examine the association between prior day's event on the current day's outcome, as well as the extent to which a prior day's event makes an individual more or less responsive to an event today. Finally, we provide a detailed description of the procedures necessary to prepare the dataset, and secondary analysis of data from a recently published study illustrates our recommendations.
研究人员早就认识到日记法在研究思想、感觉和行为变化方面的作用。借鉴每日事件既有“当下”后果又有随时间推移的前瞻性后果的观点，我们描述了一个强调日记数据时间方面的概念和统计框架。包括时间效应（即滞后和同期×滞后项）通过允许研究人员检查前一天的事件与当前一天的结果之间的关联，以及前一天的事件使个人对今天的事件更敏感或不敏感的程度，扩展了正在测试的假设的范围。最后，我们提供了准备数据集所需的详细过程描述，以及对最近发表的一项研究数据的二次分析说明了我们的建议。
