The Micro-Randomized Trial for Developing Digital Interventions: Experimental Design and Data Analysis Considerations
开发数字干预的微随机试验:实验设计与数据分析考量
Just-in-time adaptive interventions (JITAIs) are time-varying adaptive interventions that use frequent opportunities for the intervention to be adapted--weekly, daily, or even many times a day. The micro-randomized trial (MRT) has emerged for use in informing the construction of JITAIs. MRTs can be used to address research questions about whether and under what circumstances JITAI components are effective, with the ultimate objective of developing effective and efficient…
